What is the main point of silicon carbide production
Silicon carbide abrasive usually quartz, petroleum coke as the main raw materials. They are processed mechanically in the material preparation process to become the appropriate particle size, and then silicon carbide manufacturers according to chemical calculations, mixed into the charge. The abrasive adjusts the permeability of the charge, and the appropriate amount of wood chips should be added when the charge is distributed. When producing green silicon carbide, the charge should be added with salt.
Silicon carbide manufacturers in the process of producing silicon carbide, the above various materials are taken out in different operation stages of electric furnace. Sometimes the order of removal is not consistent with the above order, and it is not collected exactly according to the above classification. The usual operation classification is, spent material and a part of silicon carbide unified as spent material collection; A part of silicon carbide and amorphous, two - grade product collection, generally known as the return charge. The adhesive is sometimes collected in the return charge, and sometimes a part of the larger and more tightly bonded, containing more impurities to abandon it.
