In 2022, it provided N08120 forgings for equipment for a domestic polysilicon project, which has been successfully delivered and guaranteed in quality, breaking the previous situation that the material has long relied on imports.In January 2022, Jiangxi Baoshunchang Special Alloy Co., Ltd. undertook the first domestically produced flange forgings of N08120 cold hydrogenation reactor for a large chemical enterprise in China.
All departments of the company cooperated closely and worked together to tackle key problems, and finally completed the production and delivery tasks with high quality as scheduled, achieving a new breakthrough in material procurement in the field of domestic polysilicon and other new energy equipment manufacturing.
Under the new situation of "double carbon" superimposed with "localization substitution", the transformation and upgrading of China's traditional equipment manufacturing materials are facing huge challenges. The development of new energy materials industry needs to be broken through, and the implementation of core materials in key areas needs to be accelerated. Under the guidance of the "dual carbon" strategy, photovoltaic, hydrogen energy, new energy and other industries have developed at a high speed. Clean low-carbon new energy represented by photovoltaic has become the main force in the transformation of the energy industry.
Polycrystalline silicon is the main raw material for photovoltaic panels, and its core production equipment - cold hydrogenation reactor is mostly made of N08810 nickel base alloy. This material has strict requirements for high temperature and pressure resistance, high wear resistance, strong corrosion resistance and other properties, and has always relied on imports, it’s a key link in polysilicon production. In the new situation,The key to the development of new materials and equipment manufacturing lies in enterprises.
With the continuous increase of national policies and the continuous improvement of the industry's technical level, the supply of polysilicon materials used to manufacture photovoltaic panels also exceeds the demand. Many enterprises in the new energy industry have planned to build new polysilicon projects, and the requirements for polysilicon manufacturing equipment have gradually become larger and lighter. In order to solve such problems, many owners and design institutes prefer to use N08120 nickel base alloy materials to manufacture polysilicon production equipment.
Compared with N08810, on the basis of close manufacturing cost, N08120 has superior performance, high temperature strength and oxidation resistance. It not only extends the service life of the product, but also improves the tensile strength. It can be widely used in high temperature, high pressure and other harsh working environments.
Therefore, N08120 becomes a better choice for polysilicon production equipment manufacturing materials. However, N08,120 materials have been imported for a long time, with limited import capacity, long delivery cycle and high import prices, which have seriously restricted the development of Chinese enterprises.
At present, the homemade N08120 cold hydrogenation fluidized bed reactor flange forgings manufactured and successfully delivered by Jiangxi Baoshunchang Special Alloy Co., Ltd. are another substantial progress in the issue of "neck" of key materials in the field of new energy equipment manufacturing, and have made positive contributions to continue to promote the development and upgrading of nickel based alloys, realize the comprehensive replacement of imported materials and the development of China's new energy industry.
