At present, the raw materials used in the production of electrode paste are basically calcined anthracite, metallurgical coke powder, and medium temperature coal pitch; it should be updated to use electric calcined anthracite, calcined petroleum coke, and modified coal pitch. The specific resistance of ordinary calcined anthracite is 70% higher than that of electrically calcined anthracite; the specific resistance of metallurgical coke powder is 2.5 times that of calcined petroleum coke, and the toluene insoluble matter and coking value of modified coal tar pitch are higher than that of medium temperature coal tar pitch. After the replacement of the raw materials, the quality of the electrode paste has improved to a higher level.
Although the replacement of raw materials will increase the cost of electrode paste and increase the price of electrode paste, it will inevitably reduce the production cost of electrode paste manufacturers and improve the stability and product quality of the manufacturers. The total cost of using the manufacturer will not increase or increase little. Some electrode paste manufacturers update one or two kinds of raw materials, but they do not update all of them. It feels that there is no effect or the effect is not obvious. In fact, the overall integration effect has not been reflected, especially the use of modified coal pitch still has technical problems, which require professional technical personnel to guide.
Equipment to be “renewed”
Equipment is the hardware produced by the enterprise. In today’s advocating technological advancement, if the hardware is not hard, it means that the competitiveness is not strong. Although some companies have also updated some of their equipment, the overall equipment is not good enough. It must be fully equipped from crushing, screening, grinding, batching, kneading, and molding. Especially paste molding machines are indispensable. The paste forming machine can not only produce large lumps of paste into small lumps, but also increase the plasticity of the electrode paste, and solve the voids that are easily formed when the large lumps are melted in the furnace during use. Improve the use effect of electrode paste.
