本文总结了本厂利用现有真空冶炼设备,独创性地使用成本低廉的真空铬铁作原料,利用真空感应——电子束轰击熔炼法和独自研究成功使用真空感应——真空自耗电极重熔法,以工业规模冶炼出高质量的000Cr26Mo、000Cr26MoNb、000Cr28Mo4,000Cr28Mo4Ni2,000Cr28Mo2及000Cr30Mo2等超纯高铬铁素铁不锈钢的冶炼工艺、热加工过程和解决脆化等方面的情况。阐述了可将真空感应——电子束轰击熔炼工艺中,可将二次电子束重熔改为一次电子束重熔。用上述钢加工成的各类型材,经试验或实际应用,效果良好。
This paper summarizes our use of existing vacuum smelting equipment, originality using low-cost vacuum ferrochrome as raw material, the use of vacuum induction - electron beam bombardment smelting method and the successful use of vacuum induction - vacuum consumable electrode weight Melting, smelting high-quality industrial scale 000Cr26Mo, 000Cr26MoNb, 000Cr28Mo4,000Cr28Mo4Ni2,000Cr28Mo2 and 000Cr30Mo2 ultra-pure high-chromium iron ferritic stainless steel smelting process, thermal processing and solve the embrittlement and so on. It is described that the vacuum induction - electron beam bombardment smelting process, the secondary electron beam remelting can be changed to a e-beam remelting. With the above-mentioned steel processed into various profiles, the test or practical application, the effect is good.
