Pig iron castings are hygroscopic materials that easily absorb moisture in the atmospheric environment. During the extrusion process, this material often undergoes hydrolysis, which seriously affects the mechanical properties of the extrudate. Therefore, in the traditional extrusion process, a corresponding drying device will be added to dry the material. This process often consumes a lot of energy. In general, during the entire extrusion process of pig iron castings, the energy consumption of dry raw materials accounts for about 40% of the total energy consumption. When pouring, the principles of high temperature baking and low temperature pouring should be followed. Increasing the tapping temperature of the molten metal is conducive to the complete melting of inclusions and slag floating, which is convenient for slag removal and degassing, and reduces the slag inclusion and porosity defects of machine tool pig iron castings. Using a lower pouring temperature is benefici...
