"Spending money is like running water!"

In the real room of Anhe Institute of Technology, Li Linguang pointed to a strange-looking device in front of him and sighed to Qin Hai.

"Lao Li and I both underestimated the difficulty of this technology, alas, ashamed to say, more than a dozen prototypes were built, and the most expensive one cost more than 500,000 yuan, and in the end it proved that we took a detour." An old professor standing with Li Linguang also said to Qin Hai with an apologetic face, this person is Professor Yue Kun of the Department of Mechanical Engineering, and he is a big expert in mechanical design.

Qin Hai handed over the task of developing the thermal spraying process to Li Linguang, and allocated 200,000 research funds in the early stage. Who would have thought that at the beginning of the research, Li Linguang found that money was really a useless thing. The 200,000 yuan in the early stage was all spent in a few days, and Song Hongxuan urgently allocated 2 million yuan, and it didn't take long for it to be spent cleanly, so that Li Linguang didn't know how to explain to Qin Hai.

In fact, Qin Hai was fully prepared for the expenses required to study this process. The development of thermal spraying technology abroad is based on tens of millions of dollars to smash in, Qin Hai has the advantage of foresight, can avoid some senseless waste, but some necessary steps still have to go through again, just this time down, without millions of yuan can not be stopped.

Regarding the principle of thermal spraying process, Qin Hai explained it very clearly to Li Linguang. What Li Linguang has to do is to cooperate with Yue Kun to manufacture a spraying equipment and turn the principle into actual production capacity.

Huge expenses are spent on the manufacture of equipment, thermal spraying is the use of high temperature and high pressure generated by the combustion of fuel in a closed container to promote the spraying material onto the substrate to form a coating. Therefore, the spraying equipment must have the ability to withstand high temperatures and high pressures, and it needs to be able to control the spraying jet finely, and its complexity is self-evident.

Li Linguang and Yue Kun were originally based on the principle of spending less money and doing more. I tried to use ordinary materials to make the spray gun, but it turned out that the spray gun was deformed after a few uses, and even almost caused a burst accident. Later, they began to use high-end alloy materials and processed them with the help of imported precision machining equipment, and the cost of equipment rose linearly.

When Li Linguang spent the first 200,000 yuan. I was very uneasy in my heart, and explained to Qin Hai repeatedly on the phone. Qin Hai just laughed and told Li Linguang, this is all expected, and the actual cost is probably 10 or 20 times higher than this figure, so let Li Linguang do it.

If it was left a year ago, Qin Hai would not have had the confidence to let Li Linguang spend his money freely. In the past year, due to the continuous development of the production of Pingyuan Special Steel Plant and North Second Iron and Steel Enterprise, Qinhai has earned tens of millions of yuan in profits. It already has the ability to tackle certain technical difficulties. Li Linguang's real yàn cost millions of yuan, but Qin Hai was not nervous, he knew that the return on these real yàns was far greater than the initial investment.

Qin Hai's other enterprises, including Qujiang Cement Factory, Quwu Industrial Ceramics Factory, Dongyao Plastic Factory and Haijie Technology Company, are still in the early stages of development, and although they have some profits, they are only enough for their own expansion and reproduction, and cannot provide financial support for Qin Hai. But. Qin Hai has enough patience to wait for these companies to grow slowly, and what he will do in the future is far more complicated than designing a thermal spray equipment. The amount of money needed is also hundredfold or even a thousand times the current scale of investment.

With Qin Hai's support, Li Linguang was a little bolder and began to manufacture the second and third equipment. Costs are rising, but progress is also very noticeable. The durability of the equipment has increased, and the spraying results have been improved. Qin Hai asked Leng Yuming to send a large number of rotary tillage blades from Qingfeng Factory for Li Linguang to carry out the practice.

After the real yàn. Li Linguang found that after spraying the titanium nitride coating, the wear resistance of the rotary tillage blade was greatly improved, reaching more than three times that of the surfacing process. That is to say, if the original process can make the durable life of the blade reach 1200 acres. Then the spraying process can at least make it reach more than 3600 acres.

"Xiao Qin, we succeeded!" Li Linguang excitedly said to Qin Poster on the phone.

"How uniform is the coating? Is the stable performance of spraying quality guaranteed? Can the cost per piece be compressed to no more than 150% of the overlay process? How is the durability of the spraying equipment...... Qin Hai was not moved by Li Linguang's news, and he put forward a series of new requirements to Li Linguang.

"This ......" Li Linguang was a little wilted, and the questions raised by Qin Hai were their weaknesses. The quality of the workpiece they process is not stable, and the difference between the wear resistance of good quality and poor quality is several times, almost a bit of relying on the sky to eat.

"Xiao Qin, if you want to improve the stability of high quality, the spraying equipment needs to be improved, and the equipment cost will probably increase by more than 100,000 ...... if you want to add a module that automatically adjusts the workpiece," Li Linguang reminded timidly.

"I'll ask Lao Song to allocate another 2 million to you." Qin Hai said loudly.

Qin Hai knows that in the field of materials science, the application of a technology is not complicated, and the most difficult part is to transform the results of the real laboratory into production technology. The principle of thermal spraying is known to Qin Hai, and it is not surprising that it can increase the wear resistance of the blade by 3 times in the real room. If their research is limited to this stage, they may be able to produce a few world-class academic papers, but they will not be able to form a money-making industry. For papers, at least Qin Hai is not uncommon, he wants the huge business opportunities brought by this process.

Li Linguang couldn't remember how much money he spent, he only knew that his concept of money was becoming more and more indifferent. 50,000, 100,000, 200,000, 400,000...... The manufacturing cost of the equipment has doubled, but the process requirements proposed by Qin Hai are getting closer and closer. This time, he invited Qin Hai to Hongze, which was to let Qin Hai see the latest equipment they had made.

"This equipment, the 22nd version we designed, can adapt to a variety of shapes of workpiece surface spraying, the coating is firm, the uniformity is good, the spraying speed can reach 4 seconds for a workpiece, and the service life is more than 1 million pieces......" Li Linguang introduced the technical performance of the new thermal spraying machine to Qin Hai.

"What about the cost?" Qin Hai asked.

"About 600,000, but if mass production can be realized, the cost can be reduced a little more." Yue Kun interjected on the side, he is engaged in machinery, and he knows the cost of equipment best.

"It's too ugly......" Qin Hai said as he stared at the device and shook his head. The equipment used in this kind of real yàn room is simple because of ugliness, and there is no pursuit of appearance at all. However, this also seems to be in line with a common saying in later generations: the turtle is not the soil, and the combat effectiveness is five. The cutting-edge equipment developed by Chinese enterprises is all full of a strong smell of turtles.

"Xiao Qin, the equipment is just for use, what's the use of looking good or not?" Li Linguang was very dissatisfied with Qin Hai's views. In his opinion, this device is full of rugged beauty, and the performance is so good, what is not to be satisfied with?

Qin Hai didn't pay attention to Li Linguang, but directly instructed Yue Kun: "Professor Yue, please continue to improve this machine, improve its automation level, and find someone to design the appearance, especially to meet the needs of factories in European and American countries." ”

"European and American countries?" Yue Kun was stunned for a moment, "Xiao Qin, do you mean that you plan to sell this equipment to European and American countries?" ”

"Why not?" Qin Hai asked with a smile, "Professor Yue, at present, we are already at the forefront of the world in terms of thermal spraying, and once this news spreads, manufacturers from all over the world will have to buy equipment from us." I can't just take a device like this and ask someone for $1 million, right? ”

"$1,000,000!" Li Linguang stuck out his tongue out of the elder, "Xiao Qin, do you really dare to quote, Lao Yue said just now, this equipment is 600,000 yuan, even if we add a cover to it and make it beautiful, you can't sell it for 1 million US dollars, right?" Bid $200,000, I think it's a huge profit. ”

Qin Hai hated the iron and said with a grudge: "Mr. Li, you just calculated the cost of the equipment, isn't our patented technology valuable?" You know very well how useful thermal spraying is, and it's not an exaggeration to describe it as a little gold, right? As the owner of the patent and the only equipment manufacturer, we will not sell at a high price at this time, when will we wait? ”

"I think it makes sense." Yue Kun came back to his senses first, he patted Li Linguang on the shoulder, and said: "Lao Li, think about it, let's buy real equipment from abroad, a small analyzer, it is also tens of thousands of dollars, how many materials can be used?" Why, isn't it because people have technology? Now that we have the technology, wouldn't it be a loss if we didn't turn around and sell them for one or two hundred dollars? ”

Qin Hai clapped his hands and said, "That's right, Professor Yue's words are to the point." We've always been buying other people's things and letting others slaughter them, and now that we have the skills, it's time to cut the meat of others. Mr. Li, Professor Yue, the two of you will work hard for a few more days, continue to improve the equipment, and then organize the students to draw the drawings, and I will be ready to find a company to carry out mass production. When the International Farming Equipment Expo is over, our thermal spraying process will definitely be a hit, and at that time, we will wait for foreign manufacturers to snap up our thermal spraying machines. ”

"Good!" Li Linguang came to love, "Hearing Xiao Qin say this, I'm down-to-earth." I was a little distressed by spending so much money in front. If our equipment can be sold for 1 million US dollars, sell two or three units, the initial investment will all be earned, and the rest is the net money, which is too easy to earn! (To be continued......)

PS: I had a day of meetings and I didn't get home until 10 p.m....... There will be another day tomorrow during the day.

No way, people are in the rivers and lakes.
