Rebirth 2008: I Can Make Money Reading Chapter 77

The office location of the newly established Naixue Catering Management Company in H City, Jiangnan Province is temporarily set in the Xinghai Machinery Office Building, with a registered capital of 5 million yuan. Song Xuelu is helping Muyang prepare the company's articles of association, system, recruitment and training materials and other matters. Not a single soldier.

Mu Yang didn't want Song Xuelu to do things that were too tiring.

When two people do things together, they don't feel so irritable, and they talk about light and interesting topics in their free time.

Song Xuelu also faced a lot of things. Sometimes she didn't want to disturb Mu Yang, so she had to ask the employees of Xinghai Machinery Co., Ltd., or check the information herself, or consult a consulting company.

The shop is still under investigation, and the recruitment process will start immediately after the shop starts to decorate.

Song Xuelu usually has classes at school, but she has to learn to drive on weekends. She has no classes or at night to come to the company to learn how to set up a company. She is a little busy, but she enjoys it and feels that she is growing every day.

The roommates in their dormitory saw that she was busy all day long, but did not know what to do.

Tired, Song Xuelu went to Mu Yang's office for a walk.

On the weekend morning, she saw Mu Yang drawing pictures in front of the computer desk, and after a while, she couldn't see any clues.

Seeing that there was almost no boiling water in Muyang's cup, he poured her a cup of hot water.

After Muyang stopped painting, she asked curiously, "Yangyang, what are you painting?"

Muyang replied: "Xinghai's next plan is to build hot wire TIG welding equipment for nickel alloy 625."

"I have to redo the equipment. Can't the company's plasma surfacing weld nickel alloys?"

"The difference is that the heat energy of plasma surfacing is too dissipated, and nickel alloys are prone to thermal cracks, which crack during welding."

Muyang explained to her that surfacing nickel alloy 625 is different from surfacing welding STL6. Cobalt-based alloy surfacing is for wear resistance and requires high hardness, while surfacing nickel alloy is for corrosion resistance.

Alloy 625 is an austenitic superalloy with nickel as the main component, about 22% Cr and 59%-63% Ni.

It has excellent properties of broad oxidation and corrosion resistance.

Why do nickel alloys have such properties?

For example, stainless steel 304, which is common in life, contains more than 13% Cr chromium, which will form a protective film of chromium oxide on the metal surface, so it has corrosion resistance, but it will also rust in seawater, while 625 alloy is in seawater. will not rust.

The corrosion resistance equivalent PREN value of nickel alloy 625 is 40.3, while the PREN value of common stainless steel 304 is 18.0.

More than twice as much!

The corrosion resistance may be exponential, and it can be seen that the corrosion resistance of 625 alloy is many times stronger than that of stainless steel 304.

Valves in some working conditions have anti-corrosion effects on chloride-contaminated media such as seawater, neutral salt and salt water. Using 304 will not work, but using nickel alloy to cover the surface can achieve corrosion resistance.

However, because the price of nickel alloy is very expensive, one kilogram can reach hundreds of yuan, the whole valve is very heavy, several inches can reach hundreds of kilograms, and the large size is more than one ton, so it is impossible to use nickel alloy to manufacture, generally the matrix is ​​made of nickel alloy. For cheap carbon steel, the surface of the circulating medium is surfacing and covered with nickel alloy, which can reduce the use of expensive nickel alloy.

Song Xuelu listened carefully to Mu Yang's explanation and probably understood something.

But there are some issues that I still don't understand.

For example, what are the advantages of Muyang's new equipment?

Muyang also explained: "In fact, it is similar to the advantages of surfacing STL6, that is, the surfacing layer can be well controlled, which can save 35% of welding materials.

Of course, the traditional MIG welding efficiency is higher, reaching 3KG/hour in one hour, and the hot wire automatic TIG welding I am going to use, the efficiency is only 1.2KG/hour.

However, labor and equipment costs are nothing compared to expensive welding consumables.

For example, for a ball valve with a diameter of 10 inches, the surfacing area of ​​the sphere, channel and inner valve body cavity is about 24,000 square centimeters. The thickness of conventional MIG surfacing nickel alloy is 6 mm, the surfacing weight is 112 kg of welding material, and the welding time is about 37 hours.

The unit price of nickel alloy 625 including tax is 250 yuan/KG, which is not much different from STL6, and the cost of light welding material is 28,000 yuan.

If you use hot wire TIG automatic welding, you only need to stack 4 mm thick to meet the requirements, which can save 35% of welding materials and save nearly 10,000 yuan!

Although the welding time is about 60 hours, which is 1.62 times that of conventional MIG welding, one person can take care of two equipment, the efficiency is not slow, and other costs are not much different. "

Mu Yang said a bunch of technical data, Song Xuelu probably understood it, but some knowledge points were difficult to understand.

In short, one word!

Hot wire TIG welding can save 35% welding material!

Muyang's new equipment makes money by saving welding consumables, because nickel alloy welding consumables are too expensive.

"Hee hee, our current OEM STL6 price is 600 yuan/KG, how much is the OEM nickel alloy 625?"

"It is lower than the surfacing STL6, and the conventional foundry fee is 500 yuan/KG, which gives a gross profit space of 250 yuan/KG. If it is hot wire TIG welding..."

Mu Yang took out the calculator, did the math, and said:

"Actually, there is a gross profit margin of 337.5 yuan/KG."

Song Xuelu also thought about it: "Compared to the profit of surfacing STL6, it is not much, and the welding efficiency is not high."

Mu Yang smiled and said, "The profit margin cannot be compared with that of surfacing STL6, but the situation is different."

A self-made hot wire TIG automatic welding equipment costs 80,000 yuan. According to ten hours a day and 330 days a year, it can process about 4000KG of welding materials a year. In fact, according to the order of MIG, the OEM of 6153KG of welding materials, gross profit 2.07 million yuan!

However, one welder can manage 2 sets of equipment, and the annual pre-tax profit is about 3.95 million yuan, excluding labor and electrical costs.

At present, the annual pre-tax profit of a plasma surfacing STL6 is about 3.62 million yuan.

The above calculations are based on the case that the order quantity is sufficient.

The profit of a single hot wire TIG welding is not as good as that of the surfacing STL6, but the per capita profit is higher.

And, but this is to expand the business on the original partner, there is no need to spend any effort to expand. UU reading www.uukanshu.com

A welder can create a profit of 3.62 million yuan a year for the company, which is very profitable.

This is also due to the large amount of surfacing welding of a single valve, and most of the valves are more than 8 inches, so the profit of a single valve OEM is high.

At present, the domestic market for surfacing nickel alloy 625 is also 23 billion yuan. Muyang plans to make 30 hot wire TIG equipment first. If the order volume is sufficient, it is not a problem to earn 50 to 60 million yuan a year.

If there are more orders, it is possible to break through 100 million profit a year.

This profit is purely to expand the business on the basis of the original partner.

Compared with plasma spray welding equipment, the equipment and process are not complicated, but compared with China, the current hot wire TIG welding for surfacing nickel alloy is the first.

Muyang has already drawn the 3D drawings, and is now producing the drawings for the workshop to process, and giving the Purchasing Department a list to help purchase standard parts.

For this piece of equipment, he personally took workers and welding engineers to install and debug one, and after the employees learned it, the latter equipment would be assembled and debugged for the employees.

This kind of equipment has been available in China for a long time. It is more troublesome to debug the process. It can be transferred out after some time. It is not easy to keep secret, but the patent application is applied.

the most important is,

Others have this equipment, but they don't have the strong cooperation channels of Xinghai Machinery Company, so they can't get so many orders.

It can no longer compete with Xinghai Machinery!

"Xuelu, I have already drawn a picture of this hot wire TIG welding equipment, and the staff of the company will be responsible for the rest of the work. I will continue to inspect the store with you tomorrow, rent the store as soon as possible, and open it for decoration." Muyang has been busy recently. Regarding the new equipment, the tea shop was delayed.

"Well, okay, I'll be happy if I can help you." Song Xuelu smiled.
