轧辊横移式轧机的出现为板带生产带来了新的活力,为人们提供了一个新的、有效的板形调整手段。根据我国的国情和国外的改造经验,实现四辊轧机改造的主要机型应当是:热轧带钢轧机:工作辊横移+双阶梯支撑辊+工作辊弯曲;冷轧带钢轧机:CVC+双阶梯支撑辊+工作辊弯曲。我国板带钢轧机实现由传统四辊轧机向工作辊横移式轧机的过渡势在必行。
The emergence of roll traversing mill has brought new vitality to the production of the strip and provided a new and effective adjustment method for the strip shape. According to China’s national conditions and foreign experience in transformation, to achieve four-high rolling mill transformation of the main models should be: hot-rolled strip mill: work roll shift + double-step support roll + work roll bending; cold strip mill: CVC + Step support roller + work roll bending. China’s strip mill to achieve from the traditional four-roll mill to the work roll shifting mill transition is imperative.
