"Shenma" to rebuild 10 billion green low-carbon new material industry chain

In early summer, Guizhou xingren baling town heavy industrial park witnessed a new scene of the opening of a new bureau of Zhejiang-Guizhou key projects in east-west industrial cooperation: on June 2, Guizhou huajun aluminum technology co., ltd. invested by Ningbo shenma group, the project "construction of 300000 tons of copper-aluminum eutectic plate and strip production line in xingren city" was put into operation. only electrolytic aluminum liquid with high temperature of 700 was injected into the smelting into the smelting furnace, and copper strip was introduced synchronously during the conversion from liquid phase to solid phase, solid copper plate and semi-solid aluminum liquid through the casting roll of high temperature and high pressure rolling, the two metal interfaces for atomic co-penetration crystallization, and finally slowly "spit out" a unique copper-aluminum eutectic plate strip.

At this moment, Ningbo Shenma Group's "Xingren City Annual Output of 100000 Tons of Aluminum-based Alloy Plate and Strip Production Line and Deep Processing of Aluminum Products" project, which was put into operation in early winter three years ago, has achieved fruitful results and has formed an annual output of 80000 tons of series of aluminum wafers. The scale has stabilized the dominant position in the domestic cooking utensil base material market segment. And in 2021 into the field of new energy vehicle battery production, become a new growth point. Last year, the company generated an output value of 1.17 billion yuan, up 17% year on year. In the first quarter of this year, the output value exceeded 0.4 billion yuan, up 35% year on year.

Xu Yinchang, chairman of the company, said when talking about the investment value of the new project, "The existing traditional aluminum alloy plate and strip products have low technical threshold and fierce homogenization competition. Along with the green low-carbon economy, the company is committed to the development of low-carbon, lightweight, functional advanced basic materials as an effective path for high-quality sustainable development of enterprises, to achieve the company's aluminum-based new materials industry base leap."

Resolve into action, solve the "pain point" to find business opportunities. The original group found in the new energy vehicle battery shell for customers that the negative pole of its battery is copper-aluminum composite material, and most of them use friction welding technology. Its technology and equipment are imported from abroad, with high cost and low efficiency. Therefore, aiming at the new track of lithium battery, starting from October last year, based on the processing of aluminum-based alloy plate and strip, it extends to copper-aluminum composite plate and strip. Here, based on self-technology, carefully analyze the advantages and disadvantages of other processes to produce copper-aluminum composite plates, learn from and use, overcome difficulties, break through the technical problems of solid-liquid casting and rolling, and master the production of high-performance copper-aluminum eutectic plate and strip Independent intellectual property rights, the technology is becoming more and more mature, and 15 invention patents have been declared. It not only increases the added value, but also expands the larger blue ocean market space, optimizes the allocation of resources, and extends the application fields of the company's aluminum substrate strip from cookware, electrical appliances, new energy vehicle batteries to electrician, electrical, electronic, energy storage, photovoltaic, military industry, shipbuilding, rail transit, construction and other fields.

According to a recent inspection by an authoritative organization in China, the copper-aluminum eutectic plate strip produced by the company has a subversive upgrade in peel strength, current load, conductivity, tensile strength, shear strength, composition density and other properties compared with the copper-aluminum composite plate strip produced by the traditional process. The product to aluminum instead of copper, its performance is better than copper, can reduce the user's original pure copper application of about 35% of the material cost, to alleviate China's more aluminum less copper status quo, promote the national double "carbon" economy and national scarce resources reserve strategy has a great role in promoting.

In order to consolidate the achievements of poverty alleviation cooperation and devote itself to rural revitalization, Shenma Group will transfer energy and environmental protection to different places, and the final output marketing will be collected in Cixi headquarters. It will strive to build a seamless link between Guizhou and Cixi industrial chain. It is planned to implement the project of "construction of 300000 tons of copper-aluminum eutectic plate and strip intensive processing production line" in Cixi Binhai Economic Development Zone simultaneously. The project is planned to start construction in the second half of 2023, it is estimated that the output value will reach 25 billion yuan after reaching the production capacity, and the industrial chain of 10 billion green and low-carbon new materials will be rebuilt.
