Chapter 2409
Electric welding is a metal processing technology that emerged with the development of the electric power industry. In its original history, the electric welding technology that could really be used for production was only invented at the end of the 19th century. Although Haihan's travelers have long mastered this technology, they have not been able to apply this technology to current industrial production because the welding materials required for electric welding cannot be manufactured by themselves. Yu Feng's breakthrough in this area is of great significance to Haihan's industrialization process. The Executive Committee also attaches great importance to it. Not only did Bai Kesi, who is in charge of industry, come to today's technical verification session, but even the Minister of National Defense Yan Chujie also specially Come join in the fun.
Yu Feng's machinery factory has military production tasks all year round, so he has dealt with the Ministry of National Defense a lot, and he is familiar with Yan Chujie. Of course, he understands why the other party is interested in this technology - if the electric welding process can be widely used If applied to industrial production, ordnance technology will also be greatly improved. For example, the ironclad ship that the Navy has always dreamed of may be released much earlier.
"You two, please come to my office and sit for a while. The process test will have to wait a little longer." Yu Feng raised his wrist to check the time on his watch, and said to the two senior executive committee officials: "It won't be too long, just wait for another half." Just hours.”
Yan Chujie asked in confusion: "Lao Yu, you are testing the technology. Do you have to wait for a good time before taking action?"
Yu Feng explained with a smile: "It's not that troublesome for me. Do we have to wait for the power transmission from the hydropower station? I applied for an hour at noon, so I have to wait until twelve o'clock to use the electricity."
The power generation capacity of this hydropower station built on the upper reaches of Tiandu River is relatively limited, and part of the power must ensure the power consumption of Victory Fort. In particular, the big data center set up in Fort Victory must give priority to ensuring stable power supply 24 hours a day. The various production units in Tiandu Industrial Zone can only share the remaining electric energy equally, and in order to ensure efficiency, they must arrange peak-shifting use.
Although Yu Feng's machinery factory has also pulled transmission lines, in fact, the machinery used in daily production has basically been replaced by steam-powered equipment, so it is not among the fixed transmission objects of Tiandu Hydropower Station, and it is necessary to conduct welding process testing. Only temporary electricity can be applied for.
As the Minister of Industry, the production and transmission of electricity are naturally within his scope of work. He coughed and said, "If the welding process is verified to be qualified, your electricity consumption arrangement can be adjusted according to production needs in the future. ”
Yu Feng said: "Minister Bai, there will only be more and more projects that require electricity in the future. Digging up the east wall to make up for the west wall is not an option after all. We still have to find ways to increase power generation!"
Bai Kesi nodded and said: "The flow in the upper reaches of Tiandu River is limited, and it is difficult to increase the scale of power generation. However, we have surveyed several places in the upper reaches of Linchun River and Sanya River. If everything goes well, we will Two new hydropower stations have started construction simultaneously. Once completed, they will basically solve the current power supply problem in Tiandu Industrial Zone.”
What restricts the development of Haihan's power system is not just the natural environment and engineering capabilities. In the final analysis, it still comes back to the reserve of professional talents. From a long-term perspective, whether it is the most basic electrician or an engineer who can manage power transmission and transformation equipment, it is not enough to rely solely on the technical personnel in the group of time travellers. Therefore, the training of professional talents has always restricted Haihan's ability to Some achievements have been made in this regard. Now more than ten years have passed, Haihan has finally accumulated a certain amount of talent in this area, and can finally put the expansion of power generation scale on the agenda.
Yu Feng invited Bai Kesi and Yan Chujie to sit down in his office. Although there was inevitably oil and soot everywhere in the machinery factory, Yu Feng's reception room had a dedicated person responsible for cleaning it, and it was always kept very clean. He asked the two The apprentice brought hot tea and planned to discuss some scientific research matters with Bai Kesi and Yan Chujie.
"In addition to welding, I have been tinkering with diesel engines recently. If this thing can be built, it will be of great benefit to us whether it is used as a generator or power equipment." After Yu Feng sat down, he said Straight to the point, he informed the two of his other research.
Baikes said: "But our refining process is not ideal at present. The quality of mass-produced fuel is limited and the damage to the engine will be greater. Maybe you need to talk to someone in the chemical industry department to understand the current crude oil refining process. Technology and fuel details, see if they can prepare some high-quality fuel separately for you.”
Regarding the development of fuel engines, Haihan's industrial department has actually been conducting it for several years. Design principles, materials, structures, and manufacturing processes are actually all ready-made. There are many plans in the big database, and officials have been conducting research and development work in this area. However, limited by the refining process, progress in this field is still very limited. Even if Yu Feng has the ability to build a fuel engine, Bai Kesi believes that the actual application effect will still be affected by the fuel currently available, and it should be consistent with The research and development work organized by the Ministry of Industry is not much different.
Of course, Bai Kesi will not stop Yu Feng from doing this kind of research. He is willing to spend his own money to engage in scientific research activities. Just like when he sponsored refugee orphans to study, it is a long-term investment that will more or less have a certain return in the future. If Yu Feng can really produce some good results, it will also be a good thing for Haihan.
The purpose of Yu Feng's initiative to bring this up was to report it to Bai Kesi. He only needed a nod from the Ministry of Industry. As for the specific development plan, he had his own plans and would not conflict with the officially organized development project.
Everyone chatted for a while, and soon the scheduled time came. Yu Feng's two apprentices had already prepared all the relevant equipment, but the specific operation still had to wait until Yu Feng did it himself. After all, electric welding is still a metal processing technology that is difficult to understand for people in this era, and it requires a long period of training before it can be actually operated.
"Master, a call has been sent." Huang Zhichang knocked on the door and entered the office, reporting the situation outside to Yu Feng.
"Let's go, let's get the business done first, and then we'll go have lunch!" Seeing that everything was ready, Yu Feng stood up and invited him. Bai Kesi and Yan Chujie didn't waste any time and immediately followed him out of the office.
The area used for welding tests is an area specially used for various tests. It is separated from the outside production area factory building, so there are no workers nearby at this time. Of course, even if someone wanted to join in the fun, the accompanying guards of Bai Kesi and Yan Chujie would keep them all away.
Yu Feng had prepared several bright light masks and asked his two apprentices to deliver them to Bai Kesi and Yan Chujie. After everyone present put on their masks, Yu Feng also put on his mask, turned on the power of the welding machine, picked up the welding gun and welding rods, and started operating.
The welding rods tested by Yu Feng today have two specifications: 2mm and 2.5mm. They are used to weld several 5mm thick square steel plates and several 10mm diameter steel bars that have been cut in advance, and then verify the bonding strength and strength of the welded materials. tenacity.
Yu Feng had not performed welding operations for a long time, and at this time, two senior officials from the executive committee were observing. In order to avoid mistakes, he consciously slowed down the operation speed in order to achieve the ideal result in one go. Welding effect.
However, he used the cut small square steel plates to weld two square containers, which took almost forty minutes, and then welded two steel bars. Yin Dezhi reminded him that the temperature of the welding machine was already too high and he had to pause and wait. Let the machine cool down slightly. Yu Feng stopped and looked at the time. It was about to reach the limited time for turning on the welding machine, so he decided to stop there, turned off the welding machine, and asked his apprentice to take out several welded samples for inspection one by one. After the welded square containers were naturally cooled, liquid was poured into them for sealing testing. However, one of the containers had a leak in a small place. The three of them took a magnifying glass and carefully inspected it, and finally confirmed that the leak was actually leakage. It was Yu Feng's craftsmanship problem, not the quality of the welding machine or welding rod, so the sealing test still ended in passing.
Then conduct a toughness test on the welded steel bars. First, place the welded joint of one of the steel bars on a hard material and hit it with a hammer to observe whether there are cracks in the welded joint. Huang Zhichang and Yin Dezhi took turns hammering for a long time, beating the round steel bars into square bars before cracks finally appeared. They hammered them for nearly a hundred times before the welding joint was completely broken. By this time, the fractured area had basically been hammered into iron sheets. .
The next bending test with an iron bender on the welding joint of another steel bar was also ideal. After several bending operations, there were only minor cracks in the welding joint. This is already a pretty good performance under the current conditions.
"Fortunately, I lived up to my fate!" Yu Feng finally breathed a sigh of relief after seeing the test results. After such long preparations, he was just waiting for today's acceptance process. If anything went wrong, all the previous work might be in vain, which naturally made him very nervous. Fortunately, the process and results were pretty good, and the welding effect was better than he expected. I guess Bai Kesi couldn't fault it.
"Can we only use these two specifications of welding rods at present? Can we weld larger things?" Bai Kesi was not as easy to deal with as he thought, and immediately raised a question that Yu Feng could not avoid.
Yu Feng had no choice but to respond honestly: "The specifications of the welding rods used are limited by the power of the welding machine. If we want to weld larger parts, then we will have to build a more powerful welding machine and also make a matching welding machine." Only the welding rods of the specified specifications will do.”
"Then what are the current manufacturing difficulties?" Baikes continued to ask.
Yu Feng responded: "The difficulty in making welding rods at the beginning was mainly in the raw materials. We spent a lot of time looking for the origin of these materials. If there is sufficient supply of raw materials for welding rods in the future, this stuff can be made in Changhua and Tiandu, and the production capacity will increase. The cost will naturally be lower. The manufacturing principle of an electric welding machine is not difficult, but making this thing requires a lot of copper wire, and our supply of copper wire is very unstable. For example, when I built this electric welding machine, I had to wait for the corresponding specifications of copper. I have to wait for almost three months. Therefore, the manufacturing period of the welding machine may be longer, and the corresponding cost will also increase. I think you can understand.”
"For the supply of copper wires and other materials, please make a separate list for me later so that I can coordinate these things for you." Bai Kesi was very happy and immediately said that he would solve the problems raised by Yu Feng.
"Then I'd like to thank Minister Bai first!" Yu Feng said happily.
"Don't thank me too much. If you want to order four welding machines of this specification and a batch of welding rods, how long will it take you to produce them? How will the cost be?" Bai Kesi asked.
When Yu Feng heard this, he knew that Bai Kesi was going to place an order with his factory on behalf of the Ministry of Industry, and he immediately admired his decisiveness. However, Yu Feng was not in a hurry to reply. He was very aware of the production capacity of his factory. This time he would produce four welding machines, and he had to calculate the construction period and cost. Then he said to Bai Kesi: "I have been busy all morning. I don't know if you two are hungry. Anyway, I am very hungry. Why don't we change places and talk while eating?"
"That's fine. Let's talk about it in another place." Bai Kesi was actually not in a hurry to use the welding machine. Of course, he also wanted to test Yu Feng to see if the other party had any hidden skills.
Yu Feng ordered his two apprentices to clean up the place, and he accompanied Yan Chujie and Bai Kesi to leave the machinery factory. Although there was a cafeteria in the factory, since he had to talk about business and he would need to ask Bai Kesi for some help in the future, Yu Feng felt that it was not easy to wrong these two pampered people, so he decided to go back to the city to have this meal.
The three of them took a carriage back to the city. Yu Feng found a restaurant he was familiar with and opened a secluded private room. The three of them all had their own business in the afternoon, so they didn't let the store serve wine.
"There is a more important coordination meeting in the afternoon. People from all departments are coming, and Lao Yan and I are also going to attend, so we won't drink at noon." Bai Kesi was afraid that Yu Feng would be too preoccupied, so he took the initiative to explain the reason.
Yu Feng asked curiously: "What kind of coordination is this?"
"Things in Shandong." Since Yu Feng took the initiative to ask, Bai Kesi had no intention of hiding it from him. Anyway, the relevant news could be read in the nearest newspaper.
Yu Feng suddenly said: "Are we going to transport refugees into the country again?"
Bai Kesi nodded and said: "Fushan County has already hosted tens of thousands of refugees, and more refugees will flow into the area in the future, so we must quickly allocate transportation capacity and materials and try our best to send these refugees to domestic resettlement."
Yan Chujie said: "This work involves too many regions and departments, so people from various departments have to be called together for a meeting to allocate tasks. If the operation goes smoothly, the population should be increased by tens of thousands this year."
