The next morning, Duan Yun went to the workshop to continue the debugging of the heating furnace, during which he drew a simple modification drawing according to his own modification ideas.

At present, the technology of these two stoves is old, the only good thing is that the shell is relatively thick, and the heat preservation effect is not bad, but the heating and temperature control parts are already backward, Duan Yun plans to start from this aspect to modify.

It takes a lot of time to modify this heat treatment furnace, but once the furnace modification is completed, it will greatly improve the hardness and other mechanical parameters of the gear, and the product quality will be greatly better than the gear products of the main factory, so it is worth spending a lot of time and money to do such a modification, after all, this is an important technical process that can enhance the market competitiveness of the product.

If there is more funds in the future, Duan Yun also plans to convert these two furnaces into advanced carburizing furnaces in China, so that Duan Yun can process gear products that meet international standards step by step, and cooperate with well-known domestic and even foreign automobile manufacturers to expand broader sales channels.

However, this is Duan Yun's long-term plan, and the current thing that Duan Yun wants to solve is to make gearbox products that meet domestic standards as soon as possible, first win the order of Daxing local automobile factory, and turn the enterprise into a profit, with enough capital and technology accumulation, and then start the next plan.

After drawing the modification drawings at the workshop site for a morning, Duan Yun drove out of the factory directly after work at noon and went to Daxing No. 2 Power Plant.

Duan Yun wants to buy cheap second-hand equipment, and Qian Deqiang has a very good channel.

Now the first company undertakes the construction of the second power plant in Daxing, the state investment is very large, and the other company is responsible for the maintenance and modification of the equipment of the Daxing plant all the year round, and there are many replaced equipment, many of which are still in use on the parts on the second-hand equipment, and the most important thing is that it is very cheap to buy things from Qian Deqiang, and it saves a lot of money than buying from regular manufacturers.

Duan Yun had bought things from Qian Deqiang twice before, and knew that he usually set up a stall near the construction site of the No. 2 Power Plant.

Located on the outskirts of the city, the Daxing No. 2 power plant is surrounded by vast farmland separated by a wall.

As the saying goes, relying on the mountains and the sea to eat the sea, relying on the construction site of the power plant, the local villagers have also gained a lot of benefits.

In addition to the regular workers in the establishment, the company also hired a large number of local farmers after contracting the project.

Since these farmers do not have the relevant technical skills, they are generally able to do some manual work, and there are also a large number of rural women who work as cleaners on construction sites, and the wages are not high, but they are certainly much better than farming.

For a power plant project with an investment of hundreds of millions of yuan, there are a lot of various scraps and garbage generated on the construction site every day, the most valuable of which is the waste produced by boiler pipes and steel frame gas welding and cutting, a few are alloys, most of them are general carbon steel, and there are many stainless steel scraps.

Generally speaking, these scrap iron scraps are to be recycled by the power construction project department according to the regulations, but in fact, since the construction site was opened, the recycling rate of metal scrap is not high, and some of them are quietly intercepted by the work area, such as the electrical work area will quietly cut off the installation of extra cables every year and sell them, and the money sold will be given benefits to the employees, while the boiler and plumbing work area will also intercept the large pieces of waste as the welfare of the workers of each team.

During the day, they wandered around the construction site, picking up scraps and small pieces of scrap metal, hiding them in the corners of the construction site, and many local workers working in the boiler and steam engine room would also secretly cut some steel with gas welding, and then tie it around the waist with a string of wire, and take it out of the construction site when they came home from work.

The huge construction site of several thousand people is like ants moving mountains, quietly emptying the huge amount of waste generated by the project, and these waste materials are basically purchased and digested by the nearby scrap yard.

In the past two years, the scrap yards were basically state-run, but Qian Deqiang basically monopolized the waste recycling business near the No. 2 power plant by virtue of his local connections.

There have also been state-owned scrap stations around trying to snatch this big cake from Qian Deqiang's side, but Qian Deqiang's relationship is hard, and the relevant departments don't care at all, and they are more flexible in the purchase price.

At the entrance of a simple earthen house built not far from the power plant construction site, Duan Yun stopped the car and walked down.

"Where's your boss. Seeing an old man in a padded jacket walking towards him, Duan Yun asked.

"I'm the boss. ”

"I'm talking about your money boss. ”

"Boss Qian went out just now and will be back in a while, what are you looking for him?" the old man asked.

"I'm his friend, and I'm talking to him about business. Duan Yun said with a smile.

"Ah, you're a friend of Boss Qian. When the old man heard this, he glanced at the jeep parked outside the courtyard, and immediately took out a cigarette from his pocket and handed it to Duan Yun, and then helped him light the fire.

"You're not bad business. Duan Yun asked casually when he saw all kinds of waste products piled up like a hill in the yard.

"It's okay, Boss Qian opened two stalls elsewhere after the New Year, and the business is okay when he goes back and forth this day. The old man in the padded jacket said.

"Two more stalls? It seems that Lao Qian has really become a rag king now. Duan Yun said with a smile.

"I just want to make a little money while building a power plant in the past few years, and I ...... to eat."

"Little money?" Duan Yun shook his head with a smile when he heard this, and didn't continue to ask.

In the eyes of later generations, the scrap collection station is not eye-catching, but in fact, the water is very deep, the profit is also very large, and backed by the power plant site, there is a large number of copper, iron and stainless steel waste products flow in every day, the profit is considerable, the old man in the cotton jacket said that it is just a small business, must not want to attract attention to the rhetoric.

Judging from the fact that Qian Deqiang has opened two stalls in a row, this kid must have made a lot of money in the past six months, and maybe it is more profitable than Duan Yun's antenna business, and he is no longer the little boss who just wanted to make ends meet.

Duan Yun walked around the courtyard, and as soon as the cigarette butt in his hand was thrown down, he heard a sudden sound of motorcycles outside the courtyard, and the next moment, he saw Qian Deqiang riding a motorcycle into the courtyard.
