抄録

In order to investigate the effect of vacuum-melting on properties of a ball bearing steel (JIS SUJ 2), vacuum-melting under various conditions and air-melting were performed by using commercial steels or electrolytic iron as main material for melting. The experimental results obtained were as follows: (1) The dispersions of yield of C,Si,Mn and Cr in steel were smaller on the vacuum-melting than on the air-melting. (2) Without regard to the main material for melting, vacuum-melted steel contains less gases, less “sands”, less non-metallic inclusions than those in air-melted steel. (3) The effects of holding time in vacuum on the various factors such as the chemical composition, the gaseous contents, the sand amounts and the inclusion amounts were studied and also the mutual relation among the factors was made clear.
