【Abstract】 The formation on hot charging process crack of low alloy steel ingot has been investigated. The change regularities of temperature field and stress field in the hot charging steel ingot process and reheating process were analyzed and calculated, measuring high temperature strength and plasticity of steel ingot. According to this, the formation mechanism on hot charging process crack of steel ingot is concluded, thus offering a theoretical basis for preventing hot charging process crack in production.更多还原
