1986年5月29日～6月2日在重庆由冶金部和航天部主持召开双真空冶炼34Si2MnCrMoVA 钢鉴定会。34Si2MnCrMoVA 钢是由冶金部钢铁研究总院、抚顺钢厂、太原钢铁公司,齐齐哈尔钢厂和航天部有关设计、研究所共同研制的。该项研究课题是在原电弧炉和电渣重熔冶炼的基础上,采用双真空冶炼工艺,从而明显地提高了钢的纯洁度、断裂韧度和应力腐蚀界限强度因子。经过实际应用考
May 29, 1986 to June 2 in Chongqing by the Ministry of Metallurgical and Aerospace Department held a double vacuum smelting 34Si2MnCrMoVA steel appraisal meeting. 34Si2MnCrMoVA steel by the Ministry of Metallurgical Iron and Steel Research Institute, Fushun Steel, Taiyuan Iron and Steel, Qiqihar Steel and Aerospace Department of Design, Research Institute jointly developed. The research project is based on the original electric arc furnace and ESR smelting, the use of double vacuum smelting process, which significantly improves the steel purity, fracture toughness and stress corrosion limit strength factor. After the actual test
