Casting machine bed casting process production, should follow the high-temperature furnace pouring bucket wheel guard port, low temperature casting principle. Because raise the temperature of liquid metal in favor of completely melted baked inclusions, slag floating, easy slag and degassing, reducing machine casting slag and porosity defects; pouring a lower temperature, it will help to reduce the liquid metal The gas solubility, liquid shrinkage and high temperature liquid metal cavity surface for baking the wheel guard Hom harbor facilities, to avoid holes, sticky sand and shrinkage and other defects. Therefore, to ensure the full protection of the mold cavity round Hom harbor premise product, try pouring a lower temperature. During operation of the liquid metal from the ladle called injection mold casting. Improper operation will cause insufficient water pouring, cold shuts, porosity, shrinkage and slag machine casting defects, and cause personal injury. Market research casting products, allowing enterprises in the arrangements for the production of castings, castings fully understand the consumer market. As the demand for castings, demand type, demand vendor, product requirements and other information. In a lot of information, the casting producers can choose their own and consume vast areas of the market for the production; if there is no suitable, enterprises have enough time to adjust production, the production needs of the market casting products, so as to effectively prevent the casting capacity surplus.
