There are two types of scrap steel recovered by scrap companies. A large piece of steel, such as some steel pipes, I-beams, etc., such steel needs to be cut into small pieces with a shearing machine to facilitate transportation and smelting. The other is crushed steel, including steel shavings, steel scraps, iron wire, broken iron sheets, etc., this kind of scrap steel needs to be pressed into a cube or cuboid with a side length between 20 cm and 70 cm with a baler, which is the briquetting that Mao Yaguang said, and its purpose is also to facilitate transportation and smelting.

The material composition of shear scrap is relatively simple, and the quality can be seen at a glance. Briquettes are made up of a variety of different scrap steel mixtures, which have a complex composition that affects the quality of the finished steel. More importantly, in recent years, some illegal private scrap recycling enterprises in order to seek profits, in the briquetting mixed with a variety of sundries, some steel mills spend the price of buying scrap, but buy in the cement block, which can not help but make steel mills have doubts about briquetting.

Some steel mills explicitly state that as long as the steel is sheared, no briquetting is required. Other steel mills require scrap recycling companies to label the briquetting with the name of the company, production date and other information, so that they can be held accountable when adulterated briquettes are found. As a result of such an option, the price of briquetted steel is much lower than that of shear steel. Of course, even so, the production of briquetting steel is still profitable, and Mao Yaguang's miserable sales are just a bargaining strategy.

"It's not like this problem can't be solved, right?" Han Weichang interjected again. He's still a technician at heart, and as a craft technician, he's better at creative problem-solving than anyone else, or in other words, he's a few centimeters bigger than the other technicians.

"Can Han Gong solve this problem?" Mao Yaguang looked at Han Weichang in surprise and asked.

Han Weichang walked up to a pressed steel block and kicked it with his foot. Of course, this is just a symbolic action, and the weight of a lump is about a ton, which is not something that Han Weichang can kick. He said:

"Manager Mao, look, our briquette, the cross-section is half a meter square, what is inside, no one can see, and it is not a problem to hide a cement pier, so the steel mill does not like to want such a briquette, is it so?"

"Exactly. Mao Yaguang said.

"So, if we flatten it a little bit, let's say it's only 50 millimeters thick, like a board, can we still hide a cement block in the middle?"

"You mean, pressed into flakes?" Mao Yaguang's eyes lit up. It's a great idea, and no one can tell what is hidden in a big iron lump. But if it's just a 5-centimeter-thick iron plate, it's not easy to hide something inside. The scrap steel ladle is not a complete piece like an iron plate, but there are countless gaps in the middle, with a thickness of only 5 centimeters, which can almost be seen through at a glance, and the director of the steel mill no longer has to worry about what cannot be seen in the bag.

"It's going to be a hassle to crush scrap steel into sheets, right?" asked Mao Yaguang.

Han Weichang said: "Just pressed into 50 mm sheet mass, there is no difficulty in the design of the model. However, the original thickness was 500 mm, now changed to 50 mm, each time the loading must be compressed to the original 1/10, the original pressure can be completed the work, now need to press 10 times, the work efficiency is reduced. ”

Mao Yaguang nodded: "That's right, that's what I want to say." ”

Han Weichang said: "To improve work efficiency, it is necessary to change manual loading to automatic loading, and use electromagnetic chucks to speed up loading and unpacking." Also, the original side-thrust pressurization is no longer suitable and should be changed to top-pressurized ......"

As he spoke, he took out a drawing pencil from his pocket, squatted down, and drew a schematic diagram for Mao Yaguang on the concrete floor. He draws very quickly, but the pen is very accurate, and when he pulls it, it is a straight line, and Tang Zifeng does not necessarily draw straighter than him when he takes the triangle. What he drew was not a complete mechanical design drawing, but just a schematic diagram, but in a few strokes, even Tang Zifeng understood what he wanted to express.

This old Han really has two brushes.

Tang Zifeng said silently in his heart.

Before today, Tang Zifeng always felt that Han Weichang was just a second-rate engineer who was messing around, and it was estimated that he had worked hard to get out of his current title, and then he became a sinkhole and was abducted. In the process of contact between Tang Zifeng and Han Weichang, Han Weichang has always been a character teased by Tang Zifeng, and Tang Zifeng does not have any conscience uneasiness about this, and the root cause of this is also this.

But at this moment, Tang Zifeng felt that he should be impressed by Han Weichang, this old Han was able to come up with ideas to solve the briquetting dilemma in such a short period of time, and he was also able to propose technical solutions, which was enough to prove his level. Well, shouldn't I be a little more respectful to Lao Han in the future, for example, I have to apologize after teasing him, and save some face for Lao Han.

"Good! great!"

Mao Yaguang's cheers interrupted Tang Zifeng's thoughts, Tang Zifeng turned his head to look, only to see that Han Weichang had already stood up and put away the drawing pencil, Mao Yaguang patted Han Weichang's shoulder, praised repeatedly, and a thin face faintly glowed red, which should be a sign of excitement.

"Han Gong, what you just said, can you do it all in one machine?" asked Mao Yaguang.

Han Weichang puffed up his chest and said, "There is no problem. The technical strength of our Linyi machine, can Manager Mao still believe it?"

"Trustworthy, trustworthy. Mao Yaguang said repeatedly, "The Changying brand machine tool you produced was also used when I was in the factory, and the quality is simple." ”

This is called the name of the person, the shadow of the tree, Linyi machine as the eighteen Arhat factory of the year, in the machinery industry was also famous. Over the years, the market share of the machine has been shrinking, but like Mao Yaguang's generation, their youth is associated with the "Changying" machine tool, when recalling the past, it is inevitable to attach some beautiful halo to the past. Just like many people talk about the snacks they ate when they were young, they always think that they taste the best, but in fact, it is just a kind of nostalgia.

Of course, the strength of the machine is indeed there, so many years of old enterprises, formed a set of strict production process and quality control system, as long as the good use of it, the quality of the product is still guaranteed.

"About the price ......"

After praising the technology of the Linyi machine, Mao Yaguang returned to the original problem, and he set his sights on Tang Zifeng.

Tang Zifeng didn't answer immediately, but said to Han Weichang: "Old Han, Manager Mao put forward a new request just now, isn't our original design enough?"

Han Weichang understood and replied: "That's for sure, according to Manager Mao's request just now, we have to add a lot of content on the basis of the original design." The cost should be increased by at least 1/2. ”

"What? 1/2 increase?"

Without waiting for Tang Zifeng to say anything, Mao Yaguang jumped up first: "Han Gong, you can't open your mouth like this, right? Isn't it just to change a PLC control, plus a pushing hydraulic device, by the way, there is also an automatic feeding, it's not difficult, how much can it cost?"

Tang Zifeng said with a straight face: "Manager Mao, you can't count it like this. The idea put forward by Han Gong just now can be regarded as an innovation in the international metal recycling community, right? By the way, we must immediately apply for patent protection. Think about it, just this one idea, how much profit can it bring you, and the price of your briquetting steel can be immediately raised to the level of shear steel. Even if you earn an extra 50 yuan for 1 ton, 10,000 tons is 500,000, 100,000 tons is 5 million, and 1 million tons is ......"

"Stop, stop!" Mao Yaguang couldn't listen anymore, I, a city-level scrap company, collects 1 million tons of scrap steel a year, do you think it's sand? Even if it's sand, 1 million tons a year is scary enough.

"That's it, the fixed price, 400,000 units, 4 units 1.6 million, how about it?" Mao Yaguang bid directly.

Tang Zifeng glanced at Han Weichang quickly, and Han Weichang shook his head slightly, indicating that the price was a bit low. The changes he proposed would indeed increase costs. According to Qin Zhongnian's original design, the cost of a baler is about 300,000 yuan, and after modification, the cost of one will reach about 350,000 yuan, and then maintain a quotation of 400,000 yuan, the profit will be too thin, which is unacceptable.

Tang Zifeng got the answer from Han Weichang's expression, and he said: "Lao Mao, according to our original design, there are more than 400,000 units, and now we have added PLC and automatic feeding, and you have only reached 400,000, which is completely insincere." Let's do it, we will suffer a loss, and one will count you as 600,000. ”

"600,000! You can keep it for yourself!" Mao Yaguang said loudly.

"Or, 550,000?" Tang Zifeng looked at Han Weichang, as if to ask for his opinion.

"Up to 450,000!" Mao Yaguang raised the price. He also knew that his previous offer was a little lower, you know, the price of similar products of Puji and Luoji has also reached 400,000, and the design is far from being as good as Han Weichang said.

"530,000!"

"470,000!"

"...... like this" Tang Zifeng had a wit, he looked at Mao Yaguang and said, "Old Mao, I won't bargain with you anymore." Didn't you say 470,000 units? I can promise you, but I have one condition. If you do it, I'll build you 4 units at 470,000 units. If you can't do it, then you can only buy it for 530,000 units, I am a fixed price, do you like it. What do you think?"

"What conditions?" asked Mao Yaguang.

Tang Zifeng said: "Didn't you just say that there are at least five or six cities in Xiahai Province that have a similar scale of metal recycling to your Jinyao? I supply them at 500,000 units. But you're going to have to sell me at least 20 units. ”
