川崎公司水岛厂第二炼钢车间5号双流板坯连铸机,从今年2月2日至2月25日,共计559小时连浇了625炉,刷新了今年1月6日新制钢公司吴厂同类连铸机所创铁345炉世界记录。铸坯长达83.6千米。该连铸机创连浇世界记录的原因:①确立了高速改变结晶器宽度的技术,在热轧采用定宽转力机,使炼钢和热轧完全同步;②通过改进结晶器铜板冷却技术,大幅度延长了结晶器寿命;③扩大铁水预处理量,提高了钢水清洁度;④在二次精炼确立了升温及
Kawasaki Corporation Shuidao Plant No.2 Steelmaking Plant No.5 Shuangliu Slab Continuous Casting Machine, from February 2 to February 25 this year, a total of 559 hours with a pouring 625 furnaces, set a new 6 January this year, the new steel company Wuchang continuous casting machine created by the same Iron 345 world record furnace. Billet up to 83.6 km. The continuous casting machine continuous casting world record of reasons: ① established a high-speed changes in the width of the mold technology, the use of fixed-width hot rolling machine, so that steel and hot rolled completely synchronized; ② by improving the mold cooling technology , Greatly extending the life of the mold; ③ expand the amount of hot metal pretreatment, improve the cleanliness of steel; ④ established in the secondary refining temperature and
