双辊薄带连铸技术(TRC)已发展到产业化的初级阶段,如日本新日铁、德国Eurostrip、美国Castrip、韩国Postrip等公司的薄带连铸生产能力已达30～50万t/a,多炉连浇时间超过10h。介绍了多种特种合金,如髙硅电工钢(w(Si)为4.5%～6.5%)、高速钢、Invar合金、Inconel合金、TWIP钢等可用双辊薄带连铸,一次性形成毫米级薄带。由于高速冷凝,晶粒细化,成分偏析极少,生产成本低,成材率高,TRC是当前双辊薄带连铸产业化的新途径之一。
Two-roll strip casting technology (TRC) has been developed to the industrialization of the initial stage, such as Japan’s Nippon Steel, Germany Eurostrip, the United States Castrip, Postrip and other companies in the strip casting production capacity has reached 30 to 500,000 t / a, multiple furnace pouring time more than 10h. A variety of special alloys are introduced, such as 髙 silicon electrical steel (w (Si) 4.5% ~ 6.5%), high speed steel, Invar alloy, Inconel alloy, TWIP steel can be double- Thin band. Due to high-speed condensation, grain refinement, composition segregation is very small, low production costs, high yield, TRC is the current two-roll strip casting industrialization of new ways.
