一、概况 连铸技术在国内、外发展很快,目前先进工业国的连铸比已达到90％以上,连铸板坯最小厚度大于150mm,但还需进一步热轧,才能达到所要求的规格。若采用双辊式薄带坯连铸工艺则可直接铸轧成冷轧带坯,从而减少热连轧设备,节约能耗,降低成本。双辊式薄带连铸机是利用转动的双辊式代替常规连铸的固定结晶器。由于铸带与结晶器之间作同步运动,不产生磨擦,形成的带坯容易脱离,铸带速度从6米/分～100米/
I. Overview Continuous casting technology has developed rapidly at home and abroad. At present, the continuous casting ratio in advanced industrial countries has reached more than 90%. The minimum thickness of continuous casting slabs is more than 150mm. However, further hot rolling is required to achieve the required specifications. If the double-roll thin strip continuous casting process can be directly cast into cold-rolled strip, thereby reducing the hot rolling equipment, saving energy and reduce costs. Twin roll strip casting machine is the use of rotating double roll instead of conventional continuous casting fixed mold. As the casting belt and the mold for synchronous movement, does not produce friction, the formation of the strip easily detached, belt speed from 6 m / min ~ 100 m /
