Title: Method for manufacturing composite deoxidizer of molten steel and the composite deoxidizer by using the mothod thereof
Inventor: NAM CHUL WOO
IPC: C21C7/06
Filed: 2001-01-10
Abstract: PURPOSE: A complex deoxidizer is provided to obtain high-density and maintain lower melting point of pure aluminum by containing solid solution of metal pieces having a high specific gravity and a high melting point. CONSTITUTION: One or two metal with high melting point or metal hardening elements such as Fe are inputted into a melted liquid metal. A complex deoxidizer containing metal pieces as the hardening elements melted into an aluminum base metal has a density higher than a melted liquid different from a pure aluminum deoxidizer, and is diffused into a deep lower part of the melted liquid. Aluminum primarily melts and the metal pieces secondly melts into the melted liquid to maximize a deoxidizing effect of aluminum. Cost saving and steel quality are remarkably improved.
