As one of the carbon products, electrode paste products have the common points and special features of carbon products. The reason why electrode paste products are special is mainly determined by product performance. The electrode paste is the raw material of self-baking electrodes. The roasting process is completed in calcium carbide and ferroalloy ore thermoelectric furnaces, that is to say, the burning speed and time of electrode paste are variable, which is determined according to the furnace type, smelting variety, geometry and electrical parameters of the ore thermoelectric furnace. The variability of firing speed and time makes the volatile content of electrode paste products much higher than that of ordinary carbon products. This determines that electrode paste is difficult or unnecessary to use vibration forming and isostatic pressing, mainly by compression molding And extrusion. The performance of extrusion molding is basically the same as that of general carbon products, but due to the continuity and mass production of electrode paste products, domestic well-known electrode paste manufacturers basically use similar molding.
The so-called compression molding refers to the characteristics of molding, which is not the traditional molding. The pressure is not transmitted by the external pressure head, mainly relying on its own gravity to pressurize the lower electrode paste product, and the model is constantly at the bottom. Move to form molded blocks.
The advantage of this molding method is that the equipment is simple and easy to repair, the continuous performance is good, and the size of the molding block is stable and uniform, but the shortcomings are also inevitable. The main disadvantage is that the upper part has a certain connection due to the elastic aftereffect between the model blocks Due to the poor wear and release of the model, there will be a certain amount of slush in the production. During small batch production, due to the replacement of the product formula, the pressure cannot be continued, and the last batch of products will have poor molding due to the gravity of the upper product itself.
