More than 20 years ago, Germany has produced an aluminum-steel composite base pipe material. The power plant air cooling system made of it uses air as a cold source to reduce water consumption for power generation. However, the relevant technology is only available in Germany, and has formed a monopoly position in the global industry. Domestic aluminum and steel composite materials for air cooling systems in power stations can only rely on imports.
To fill the gap in the technology in China
R & D team
Independent research and development since 2008
5 years of intensive research and thousands of trials
Tens of thousands of tons of steel were used in trial production alone
Finally successfully developed Technology that can make steel and aluminum composite materials
The steel-aluminum composite fin heat pipe developed by this technology is applied to the air cooling system of the power station, which can increase the heat radiation area and increase the heat radiation speed. Under the same workload, the power station can save 75% of the average annual water consumption. This means that a 600 MW generating unit can save more than 11.25 million tons of water each year.
Since its introduction in 2013
This technology product is not only applied in China
And quickly opened up the international market
Global market share has reached 60%
Inventor of the patent——YB Metal Composite Materials Co., Ltd.
1. Higher cost performance
Based on the same performance, initially, domestic companies purchased about 30,000 yuan per ton of aluminum and steel composite materials for air cooling systems in German power plants, with a delivery period of 90 days. At present, the domestic sales price of our technical products is less than 10,000 yuan per ton. Delivery time is 15 days.
2. Break the monopoly completely
Reversed the situation that all aluminum and steel composite materials for air cooling systems in domestic power plants are dependent on imports, which reduces the domestic investment in power construction costs, at the same time, greatly reduces the consumption of water resources, and saves the relevant capital subsidy for the country.
on the basis of YB team further optimized, upgraded and Invented
"Large proportion of hot-rolled composite aluminum alloy materials
And its hot-rolled composite method "
And obtained the national patent authorization in 2016
This large proportion of hot-rolled composite aluminum alloy material not only has better performance than similar foreign products, but also can reduce the manufacturing cost by more than 20% when used to produce power station air cooling systems with the same performance. The invention patent provides guidance for the compounding of multiple metal materials, and allows many metals to be combined in proportion to display their respective optimized properties, thereby forming a composite material.
For example: 304 stainless steel is suitable for contact with food, but its magnetic permeability is poor and the cost is high; 430 stainless steel (commonly known as stainless iron) has better magnetic and thermal conductivity; aluminum alloy has fast heat transfer, large heat capacity, uniform heating, and poor magnetic permeability. Through this patented technology, the three metals can be combined to avoid weaknesses, thereby creating a safer and healthier, better heat transfer effect and more durable "composite pot", which is higher in performance and cost performance than foreign technology products.
The use of this technology to develop and produce lightweight and high-strength aluminum alloy composites for battery cooling systems in new energy vehicles makes new energy batteries more powerful and safer.
At the same time, other composite materials developed by this technology can also reduce the consumption of rare and precious metals while maintaining the original performance of the product.
At present, YB Company has taken the lead in the industry to expand this technology application area from the original power plant air cooling system to aerospace, defense military, marine engineering, new energy vehicles, electronics, household appliances and other fields, directly or indirectly becoming Huawei, Tesla, CATL, Midea, Panasonic, Supor and other domestic and foreign companies' raw material suppliers. Data show that the patented product has added 2.638 billion yuan in sales to enterprises.
Zhou Dejing said that the patent research and development cycle is long and the investment is large. The company's determination and motivation in terms of independent research and development are inseparable from the policies, funds and talents. Today, driven by the city's "mass entrepreneurship and innovation", the company pays more attention to scientific and technological innovation, actively cultivates high-value patents, invests more than 50 million yuan in scientific research each year, and has 62 invention patents around composite materials. Authorized by the state, there are more than 100 varieties of patent application products. Currently, it has the largest number and variety in the world, and is the first editor of two national industry standards related to composite materials.
