mold precision alloy steel casting

Product Details


Mold precision alloy steel casting has high dimensional accuracy, generally up to CT4-6 (sand casting is CT10~13, die casting is CT5~7). Of course, due to the complicated process of alloy steel castings, there are many factors affecting the dimensional accuracy of castings, such as shrinkage of the molding material, deformation of the investment mold, variation of the amount of the shell during heating and cooling, shrinkage of the alloy, and solidification and deformation of the casting during the process. These factors are points that require special attention during the manufacturing process to ensure the quality of the mold.

Melting period control

The main task of the melting period is to rapidly melt the solid charge into a homogeneous liquid with minimal power consumption. At the same time of melting of the charge, various physical and chemical reactions occur in the molten pool, mainly including volatilization and oxidation of elements, inhalation of molten steel, transfer and loss of heat, and floating of inclusions. Therefore, the mold precision alloy steel casting melts the slag on the molten steel surface in advance, which can reduce heat dissipation, reduce the amount of molten steel, and promote the floating of inclusions.

The correct operation of the melting period can remove about 60% of the phosphorus in the steel. For low alloy steels, phosphorus is a harmful element in steel. In the smelting process, the phosphorus content in the steel should be minimized. Generally, p<0.030% is required for high-quality steel, and p<0.015% for high-quality steel, and p<0.005% for very special requirements.
