Graphitization refers to the high temperature heat treatment process of transforming amorphous carbon into three-dimensional ordered planar hexagonal mesh laminated graphite by heating carbon products to 2300℃ or above in a high temperature electric furnace. The graphitization of carbon materials is carried out at a high temperature of 2300 ~ 3000℃. Because the combustion of fossil fuels is difficult to obtain such a high temperature, it can only be achieved by electric heating roasting in industry.
The products of Hexi have passed ISO9001 quality management system certification and obtained the export qualification of graphite electrode authorized by Chinese government. With good quality and excellent after-sales service, our products are in great demand in the world market.
