【Major Chemical Equipment】442 – Domestic N08120 material cold hydrogenation fluidized bed reactors from 2022

Thread Content

In September 2021, Lansi Heavy Equipment manufactured the first set of domestically produced cold hydrogenation reactors made from N08810 material; this achievement broke foreign companies’ monopoly on the materials used for such devices and led to new breakthroughs in the manufacturing of new energy equipment such as polysilicon in China. Compared to N08810, N08120 offers superior performance at a manufacturing cost that is similar; it has better high-temperature strength and oxidation resistance. This not only extends the service life of the product but also increases its tensile strength, allows for thinner wall thicknesses, and significantly reduces the weight of the equipment. As a result, the associated systems are less burdened, enabling widespread use in harsh working environments with high temperatures and pressures. Therefore, N08120 becomes a better choice as a material for manufacturing polysilicon production equipment. However, the long-term reliance on imports for N08120 material, coupled with limited import capacity, long delivery times, and high import prices, severely hinders the development of Chinese enterprises. Ten months later, LANSHI Heavy Equipment has once again stepped up its efforts to enhance its professional manufacturing capabilities and standards, overcoming yet another technical challenge that posed a bottleneck in the field of new energy equipment manufacturing. The domestically produced cold hydrogenation fluidized bed reactor made from N08120 material, which it is responsible for manufacturing, is set to be completed within the next month. This will be another innovative breakthrough following the first domestic use of N08810 thick plate in the manufacturing of key equipment for the photovoltaic polysilicon industry. Lanshi Heavy Equipment contributes to the development of the green industry through practical actions, advancing the progress toward the \"dual carbon\" goals.
