Large carbon steel precision castings can be cast, but the cost is higher. If the demand side does not consider cost, precision casting can be used. Generally speaking, there are more common small castings in the market.
During the casting process of large carbon steel precision castings, sand holes and pores often appear. This article summarizes the following solutions:
1: The formation of sand holes can be controlled through methods such as spray painting, improving sand mold strength, strict shaping, and box fastening technology.
2: Thoroughly deoxidize the molten steel before pouring, control the moisture content of the formed material, prevent slag from entering during the pouring of carbon steel precision castings, ensure smooth exhaust of the mold cavity and core, control the pouring temperature, speed, and time, and develop a reasonable process to control the formation of pores.
