提出了炉卷轧机支持辊辊形设计的理论和方法,并根据韶钢热轧宽板厂的实际轧制工艺情况,开发了3 450 mm四辊炉卷轧机的变接触支持辊辊形VCR,并进行了工业试验。试验效果表明:新支持辊技术明显改善了轧机的板形控制性能,提高了薄规格钢板的横向同板差水平和成材率,工作辊换辊周期延长,消除了轧辊剥落现象。 The theory and method of roll shape design for the support roll of the coiler are presented. According to the actual rolling process of the hot rolling mill in Shaoguan Iron and Steel Co., The variable contact roll roll VCR of 3 450 mm four - And conducted an industrial test. The test results show that the new support roller technology significantly improves the plate shape control performance of the rolling mill, improves the horizontal plate height difference and the yield rate of the thin gauge steel plate, prolongs the roll changing period of the work roller and eliminates the roller spalling phenomenon.
