The cold hydrogenation reactor, which is part of the 60,000-ton/year polycrystalline silicon project undertaken by Dongfang Boiler for Xinjiang Dongfang Hope New Energy Co., Ltd., has been successfully shipped. For the first time, this reactor was manufactured using domestically produced nickel alloy N08810. The cold hydrogen reactor is a key device for the production of silicon-based photovoltaic materials, and the localization of this equipment has resolved the technical bottlenecks in the manufacturing processes for such materials. The localization of this equipment represents not only the first device to be manufactured locally in the southwestern region, but also a significant achievement for Dongfang Boiler as it enters the field of equipment manufacturing for the solar photovoltaic industry. The cold hydrogenation reactor is one of the core equipment in the polysilicon production facilities within the solar photovoltaic industry chain. Imported materials have been used in all cold hydrogenation equipment currently in operation in the country; this marks the first time that thick-walled nickel alloy N08810 steel plates are utilized domestically. The successful manufacturing and shipment of the first domestic cold hydrogenation reactor made from the N08810 nickel alloy marked a significant achievement, receiving high praise from the project owner and the supervision party. This success demonstrates that Dongfang Boiler has mastered the core technologies required for manufacturing large-scale pressure vessels made from high-grade nickel alloys. By helping the polysilicon industry break free from foreign monopolies over this material, it also showcases Dongfang Boiler’s capabilities as a leading manufacturer in China, as well as the company’s commitment to fulfilling its responsibilities as a state-owned enterprise.
