为了发展我国优质合金钢的生产,冶金部为抚顺钢厂从西德引进了30/60吨VHD真空精炼电炉。这套设备采用了一系列较为先进的技术:电子计算机控制;真空脱气;氩气搅拌;电炉操作采用液压传动;电极升降调节采用以乳化液作为工作介质的电液伺服控制系统。该设备投产以来,为我国生产了大量优质合金钢。
In order to develop the production of high quality alloy steel in our country, the Ministry of Metallurgy imported 30/60 ton VHD vacuum refining electric furnace from West Germany for Fushun Steel Plant. The device uses a series of more advanced technology: computer control; vacuum degassing; argon stirring; electric furnace operation using hydraulic transmission; electrode lift adjustment using emulsion as the working medium of the electro-hydraulic servo control system. Since the equipment was put into production, a large number of high-quality alloy steel has been produced for our country.
