Smelting Technology in Electric Furnace for Thick and Large Gray Iron with High Strength
Aiming at large and thick automobile die casting as well as combining with production practice, the main factors which influence the strength of gray iron in electric furnace are investigated and the smelting technology of electric furnace for thick and large gray iron with high strength is proposed in this paper. The result shows that the tensile strength of attached test specimen or hardness of casting can meet the application requirements greatly. This smelting technology provides reference for large and thick castings smelting under similar conditions.
