On September 11, 2008, this was an exciting and memorable day for all employees of Seiko Technology. At 8:08 am on this day, the first JJL500 solar polycrystalline silicon ingot furnace, which has received wide attention from the industry, was successfully developed in Seiko Technology. This is the special equipment for polycrystalline silicon ingots with the highest weight of standard ingots at home and abroad. The research and development technology of China's solar photovoltaic core special equipment has leapt to the international leading level.
JJL500 polycrystalline silicon ingot furnace is based on the successful development of JJL240 solar polysilicon ingot furnace by Seiko Technology. With its strong technical R&D and manufacturing strength, it has been extensively and meticulously demonstrated by more than one year. Success, the product condenses the wisdom of Jinggong people, is the crystallization of the joint efforts, mutual coordination and cooperation of all parties. The product has been tested by ingot casting, and the technical indexes such as crystal growth rate, furnace vacuum degree and single furnace energy consumption have reached the design requirements. It has large production capacity, short production cycle, leading technology, and greatly reducing energy consumption. The characteristics will definitely have a strong impact on the existing domestic and international similar products and photovoltaic special equipment market structure. In the later stage, the company will enter the stage of mass production and marketing application of JJL500 solar polysilicon ingot furnace. According to the company and user unit signing, the first batch of JJL500 solar polysilicon ingot furnace will be delivered to users in December 2008.
According to authoritative data, the world's most advanced 450KG solar polysilicon ingot furnace is based on the original 240KG solar polysilicon ingot furnace production technology, and JJL500 polysilicon ingot furnace (standard ingot weight is 500KG) is Seiko A new high-tech product with independent intellectual property rights, the successful development of this product can be said to be a new milestone in the history of solar photovoltaic industry, and is of great significance to promote the development of solar photovoltaic industry at home and abroad. At the same time, the successful development of this product will also change the situation that domestic solar photovoltaic core special equipment has been relying on imports in the past, indicating the coming of the era of localization of solar photovoltaic core special equipment.
