摘要
针对CVC机型辊型曲线复杂、不利于生产的缺点,在利用原有CVC机型的工作辊横移与弯辊装置的基础上,提出一套以OWBCHCW新机型取代CVC机型的经济型轧机改造方案。通过工作辊轴向移动、液压弯辊、辊型优化等手段,在消除了工作辊与支承辊大于轧制板宽部分的有害接触区的基础上,达到任意控制板形、均匀辊间接触压力、降低辊耗的目的。该方案具有改造成本低、改造周期短的优势,非常适合中、小型冷轧企业的机型改造。
<Abstrcat>Against the shortcomings of roll shape curve being complication for CVC rolling mill, a set of economic-type mill modification scheme to replace CVC rolling mill with new type OWBC HCW rolling mill was put forward. By means of axial moving of work roll, hydraulic bending-roll and roll shape optimisation, the modified rolling mill could easily control sheet shape, uniform the contact pressure between rolls and reduce the roll consume since elimination the harmful contact zone of work roll and backing roll, which are greater than rolling plate width. The scheme has the advantages of low modification cost and short modification cycle, and very adapts to the rolling mill type modification of medium and small-sized cold-rolling enterprises.
