A N08810 cold hydrogenation reactor, the first one of this kind made in China was recently shipped from Lan Zhou LS Heavy Equipment Co., Ltd. The reactor belongs to a project of Asia Silicon Industry. The key material used to build the reactor, namely N08810 nickel-based heavy plates, were supplied by TISCO, who leads the industry by successfully delivering the key material for photovoltaic polycrystalline silicon industry. The home-made material, replacing the imported one, provides substantial support to China’s green industry and promotes the achievement of dual carbon goals.

Clean and low-carbon new energy has become the backbone energy amid the nation’s “dual carbon” targets. Supported by government policy, Chinese photovoltaic industry has made leading achievements in technological capability, generated power volume and total installed power, with a promising prospect. The main raw material for the cell panel of a photovoltaic unit is polycrystalline silicon, which is produced by cold hydrogenation reactor made from N08810 nickel-based heavy steel plates. The steel material requires extreme resistance to high temperature, high pressure, high wear and high corrosion, making it technically difficult to be made. Besides, Chinese steel producers were also stuck by the dead cycle of “no order reference – no market permits – no order reference”. Therefore, the steel used to be imported from overseas market, making it a bottleneck for China’s production of polycrystalline silicon.

Since TISCO sales team discovered the demand at the beginning of 2018, numerous communication and tests had been organized. Under the common effort from production plants, technical department, designing department, with repeated discussions with potential customers and equipment manufactures in polycrystalline silicon industry, and relying on TISCO’s remarkable R&D capability, the company finally decoded each and any puzzle and successfully delivered the N08810 Ni-based ultra-thick steel plate to China’s first home-made cold hydrogenation reactor. In the future, TISCO will actively push forward the development and upgrade of Ni-based thick steel plates, strive to replace all the imported high-end material, contribute its power to China’s new energy industry and the “dual carbon” target.
