【摘要】 針對攀長鋼公司滲碳軸承鋼G20CrNi2MoA采用¨電爐 真空處理 電渣¨生產試制的工藝中控制鋼中的[O]、高倍夾雜及碳化物帶狀組織等問題進行了生產工藝的探討,對該鋼形成批量生產,以滿足鐵路用滲碳軸承鋼的要求具有積極的意義。 更多還原
【Abstract】 Focusing on the problems such as how to control [O],inclusions and carbide banded structures in the steel,and so on,which occurred in the process of trial-producing G20CrNi2MoA carburizing bearing steel by using ¨EF VD ESR¨,this paper studied the production process of the steel so as to meet the requirements of carburizing bearing steel for railway.This research has an obvious positive significance for the batch production of the steel. 更多還原
