Abstract
PURPOSE: To make it possible to cast a steel ingot bloom which contains much hydrogen by flowing high-temperature gas through a passage for molten steel during casting prior to the casting of molten steel in a mold in a bottom pouring method.
CONSTITUTION: In the bottom casting machine consisting of injection pipe 2, pouring gate 3, molten-metal ascent nozzle 4, surface plate 5, mold 6, and feeder head sleeve 7, high-class Killed steel and other molten steel are cast from the bottom. In this case, the hot blast blower consisting of fan 8, hot blast heater 9 and blast pipe 10 heats gas, such as air and nitrogen, up to 150W500°C and then blows in from injection pipe 2 before the casting. After fire brick of injection pipe 2 and pouring gate 3 and moisture in mortar are perfectly removed with the hot blast, the fused steel is cast in mold 6 from injection pipe 2 via the bottom. Thus, the steel ingot bloom which contains hydrogen every much can be cast without a hydrogen pickup due to the moisture in injection pipe 2 and pouring gate 3.
