Abstract
PURPOSE: To easily fine the casting structure by stirring the molten metal before pouring in casting a roll for rolling of adamite system or cast iron system.
CONSTITUTION: In the case of casting a roll for rolling of adamite system or cast iron system, its pouring molten metal is stirred within a vessel in the atmosphere such as ladle under a correct temperature range determined by its molten metal composition, after which this is cast at its predetermined pouring temperature. According to this method, high effect may be obtained in the uniform fining of its casting structure, particularly primary crystal austenite.
