The problems of stainless steel precision casting technology are as follows:
Serious environmental pollution and harsh working environment
The main furnace materials used in foundry production are pig iron, scrap steel, coke, limestone, molding sand, and core sand. It mainly involves the transportation, sand mixing, molding, core making, baking, melting, pouring, cooling, sand dropping, cleaning, and post treatment of raw sand, clay, pulverized coal, resin, and other adhesives, curing agents, and used sand.
2. Low process level and poor casting quality
The design of the gating system is unreasonable. Due to improper design, defects such as air entrainment and inclusions exist, resulting in low yield and qualification rates of castings.
High energy consumption and raw material consumption
