【Major Equipment in the Chemical Engineering Sector】The first domestically produced cold hydrogenation fluidized bed reactor made of N08120 material was successfully completed between 495 and 2022

N08120 is a solution-strengthened heat-resistant alloy with extremely high strength at high temperatures and good resistance to carburization and sulfidation; it is one of the materials chosen for the manufacture of cold hydrogenation fluidized bed reactors in the polysilicon industry. Compared to N08810, at a similar manufacturing cost, N08120 offers superior high-temperature strength and oxidation resistance. This material improves tensile strength, reduces wall thickness, significantly lowers the weight of equipment, and alleviates the burden on related components. It meets the demands for larger and lighter polysilicon manufacturing equipment, and is widely used in harsh working environments such as those with high temperatures and pressures. To break foreign companies’ monopoly on the raw materials for this equipment and achieve domestic substitution, Lansi Heavy Equipment has been continuously improving its specialized manufacturing capabilities. Based on the experience gained in manufacturing domestically produced N08810 cold hydrogenation reactors, it conducted numerous tests on the domestic N08120 material regarding both the base metal itself and its weldability, accumulating a large amount of data related to manufacturing processes. It successfully completed the development tests for simulated reactor cylinders, and was also able to take on the task of developing cold hydrogenation fluidized bed reactors made from N08120 material for the core equipment of the Inner Mongolia Daquan polysilicon project. Overcoming challenges such as the pandemic and adverse market conditions, Lanxi Heavy Equipment relied on its previous research and development efforts, adopted advanced welding techniques and refined management practices in China, and solved the difficulties associated with welding new materials. The performance of these reactors met all relevant standards and technical requirements. After more than 4 months of intensive effort, China’s first domestically produced N08120 cold hydrogenation fluidized bed reactor was successfully developed, making a positive contribution to further advancing the development and improvement of nickel-based alloy thick plates, achieving complete substitution of imported materials, and promoting the growth of China’s new energy industry.
