                                                                    今朝我国冶金轧辊非正常行使的耗损占整个轧辊耗损量的30%阁下,增强企业现场打点、严酷轧制工艺、确保轧机正常运转、镌汰轧制事情,对低落轧辊耗损是极为重要的。

                                                                    当棒线材轧机行使高速钢轧辊呈现卡钢或堆钢时,该当即停水,敏捷将上辊抬起,,使轧材分开辊面,并同时将会萃在下辊上的轧材当即移开,使受热的轧槽在氛围中迟钝冷却。事情处理赏罚后从头出产时,必需换槽,并且要隔2个~3个槽,绝对不应承冷却水冲到或流到受热的轧槽上。假如确实无法停止而又不能换槽,则必需换辊,待其天然冷却后再从头上机行使。不然将冷却水直接浇到过热的轧槽上,轧槽易呈现裂纹。

                                                                    当板带材轧机行使高速钢轧辊呈现卡钢或堆钢时,该当即停水,敏捷将上辊抬起,并同时将轧辊卸下换上新轧辊,待轧辊在氛围中天然冷却后再从头上机行使。假如辊面状况较好,可以不消修磨直接上机行使。假如不换辊,那么从头开机后,冷却水直接浇到过热的辊面上,辊面极易呈现裂纹,出格是下辊更为严峻,从而造成轧辊破坏。
