目前苏联正在研究用电渣重熔法熔炼ШХ15,ШХ15СГ和18ХНВА钢,使金属就纯度而言,其非金属夹杂物含量达到滚珠轴承钢水平;而机械性能赶上主要的18ХНВА钢。全部熔炼试验是在结晶器内径为200和250毫米的P909设
Currently the Soviet Union is studying the use of electroslag remelting melting ШХ15, ШХ15СГ and 18ХНВА steel, the purity of the metal in terms of its non-metallic inclusions to ball bearing steel levels; and mechanical properties to catch up with the main 18ХНВА steel. All melting tests were performed on P909 molds with inner diameter of 200 and 250 mm
