电渣冶金(包括“电渣重熔”和“有衬炉电渣熔炼”)是冶金工业上的一项新技术。它的原理,是利用电流通过特种熔渣(萤石及氧化铝粉等)时产生的电阻热,作为热源来将金属自耗电极熔化的一种冶炼方法。电渣重熔法虽然最早出现于美国,但真正能够初步用于生产,是苏联在58年实现的。美、英、法、日、德等资本主义国家,六十年代先后向苏联购买专利,并大力发展和研究。据资料报导,美帝苏修已将“电渣重熔的高级合金钢,用于火箭、导弹和核技术方面”。从 Electroslag Metallurgy (“ESR” and “Lining Electroslag Remelting”) is a new technology in the metallurgical industry. Its principle is to use the current through the special slag (fluorite and alumina powder, etc.) generated when the resistance heat, as a heat source to melt the electrode metal melting a smelting method. Although ESR first appeared in the United States, it could be initially used in production, which was achieved by the Soviet Union in 58 years. The capitalist countries such as the United States, Britain, France, Japan and Germany purchased their patents from the Soviet Union in the 1960s and vigorously developed and studied them. According to the information reported, the US imperialism Su repair has “advanced slag electroslag remelting steel, used in rockets, missiles and nuclear technology.” From
