Speech by Mr. Wu Haixiang, Executive Deputy General Manager of Jinggong Technology

Jinggong Technology is the only company in China and abroad that can simultaneously produce three core equipments, such as polycrystalline silicon ingot furnace, splitting machine and multi-wire cutting machine, from ingot to slicing. The company has successfully developed the first domestic one since 2007. Since the JJL270 solar polycrystalline silicon ingot furnace, through continuous research and development investment and independent technological innovation, the special photovoltaic equipment represented by solar polycrystalline silicon ingot furnace has been highly recognized by the market and is in the leading position in the domestic similar product market, which can completely replace Imported, JJL series ingot furnace products have been upgraded from the original JJL270 (G4) to JJL500 (G5), JJL800 (G6) and JJL1200A (G7). At present, the company is carrying out the technology development and upgrading of the fifth generation JJL1500 (G8) products. It can be said that Jinggong Technology directly participated in and witnessed the development and technological progress of the core photovoltaic special equipment such as domestic solar polysilicon ingot furnace.

Mr. Shi Limin, Executive Deputy Secretary General of the New Energy Chamber of Commerce of the All-China Federation of Industry and Commerce

The JJL1200A polysilicon ingot furnace introduced at this conference is the latest generation of the company's products, representing the highest technical level of the industry, and has begun to enter the market. Compared with the previous generation, JJL1200A ingot furnace mainly has hexahedral heating and three temperature zone control, combined heat insulation screen with vertical lifting and horizontal opening and closing, bottom cooling copper plate device, large diameter furnace body which can be upgraded to G8 size, etc. Four innovation points, in addition to the technical interface of the machine, the process interface has also been upgraded. Through the aforementioned innovations and upgrades, the production efficiency of the new generation JJL1200A polysilicon ingot furnace has been greatly improved. The size of the silicon ingot has been increased from G6 to G7, and the weight of the charging has increased from 800 kg to 1200 kg, which is 40% higher than that of the G6 ingot furnace. The cycle and corner crystal orientation are further optimized; the unit energy consumption and the splitting cost are greatly reduced, and the power consumption per kilogram per spindle is less than 6.5 degrees.

Visit the scene

JJL1200A polycrystalline silicon ingot furnace is actually used by Shandong Dahai New Energy Co., Ltd., and the performance of the whole machine is stable. The average data of one month operation shows that the annual production capacity of single-layer polycrystalline silicon ingot can be increased by 35%. The yield of ingots can be increased by 6%, the unit power consumption can be reduced by 10%, and the space for further upgrading of G8 can be greatly reduced, which can greatly reduce the production cost of enterprises.
