英国钢铁公司特种钢部的River Don工厂用一台90吨的真空电弧除气装置和一台90吨以及一台30吨的电弧炉,组合起来可以生产最大重量为210吨的钢锭。为了焙炼供浇注210吨钢锭用的钢水,其中90吨在一台电弧炉中焙炼,然后送入真空电弧除气装置中进行精炼。当真空除气装置进行工作时,90吨与30吨两台电炉又继续进行熔炼和精炼,这样二台电炉和一台真空除气装置所炼得的钢水,最后将通过滴流除气装置浇入钢锭模内。
River Don, a unit of British Steel’s Special Steel Division, used a 90-ton vacuum arc degassing unit and a 90-tonne and a 30-ton EAF to produce ingots up to 210 tons in weight. In order to bake the molten steel for the pouring of 210 tons of steel ingot, 90 tons of which are baked in an electric arc furnace and then sent to a vacuum arc degassing apparatus for refining. When the vacuum degassing device to work, 90 tons and 30 tons of two electric furnace and continue to smelting and refining, so that two electric furnace and a vacuum degassing device refining the molten steel, and finally through the drip degassing device pouring Into the ingot mold.
