1、滚筒面裂纹

裂(lie)纹(wen)可以(yi)分为企业(ye)正常(chang)进行裂(lie)纹(wen)及(ji)非(fei)正常(chang)裂(lie)纹(wen),正常(chang)水平裂(lie)纹(wen)也叫(jiao)热(re)裂(lie)纹(wen),是(shi)(shi)因(yin)为中(zhong)国屡次出现温度以(yi)及(ji)循环时间发作的(de)热(re)应力(li)所构(gou)成(cheng)的(de)滚筒面逐步(bu)决(jue)裂(lie),是(shi)(shi)发作于滚筒面上的(de)一(yi)种微外表(biao)层景象;非(fei)正常(chang)裂(lie)纹(wen)是(shi)(shi)在(zai)轧制进程中(zhong)因(yin)打滑、粘钢、卡(ka)钢、堆钢、甩尾(wei)等事故主要构(gou)成(cheng)热(re)冲(chong)击产(chan)生裂(lie)纹(wen),在(zai)滚筒面外表(biao)设计(ji)部分学生构(gou)成(cheng)一(yi)个必定需要深度和(he)延展度的(de)裂(lie)纹(wen)。

2、压痕

主要(yao)它是指在生(sheng)产过(guo)程中,用(yong)于清洁的(de)氧(yang)化皮因素,如(ru)(ru)外来物质如(ru)(ru)压(ya)配合,鼓(gu)或连续分布的(de)不规则形状的(de)凹(ao)陷的(de)系(xi)列等的(de)表(biao)面的(de)发(fa)作。

3、氧化膜掉(diao)落

轧(ya)制(zhi)开(kai)端,通过这样(yang)一段工作时间烫辊后,在(zai)滚(gun)(gun)筒(tong)(tong)外(wai)表可以构(gou)(gou)成(cheng)一层银灰(hui)色(se)或浅蓝(lan)色(se)较薄的氧(yang)(yang)(yang)化膜(mo)(mo),其对维护(hu)滚(gun)(gun)筒(tong)(tong)面(mian)、提(ti)高(gao)轧(ya)件外(wai)表以及质量(liang)问题(ti)十分具有(you)重要(yao),因为不同轧(ya)制(zhi)力的重复(fu)使用(yong)效果,构(gou)(gou)成(cheng)部分氧(yang)(yang)(yang)化膜(mo)(mo)沿碳化物周围发作微(wei)裂(lie)纹(wen);当(dang)滚(gun)(gun)筒(tong)(tong)冷(leng)却(que)系统(tong)才能发展不足,滚(gun)(gun)筒(tong)(tong)面(mian)很难实现构(gou)(gou)成(cheng)结构(gou)(gou)致(zhi)密的氧(yang)(yang)(yang)化膜(mo)(mo),即便(bian)企(qi)业构(gou)(gou)成(cheng)发生氧(yang)(yang)(yang)化膜(mo)(mo)也(ye)会(hui)很快就会(hui)恶化。在(zai)轧(ya)制(zhi)不合理,氧(yang)(yang)(yang)化膜(mo)(mo)在(zai)生成(cheng)教学(xue)进程(cheng)中敏(min)捷(jie)被(bei)破坏,会(hui)构(gou)(gou)成(cheng)直(zhi)接(jie)氧(yang)(yang)(yang)化膜(mo)(mo)掉落,在(zai)滚(gun)(gun)筒(tong)(tong)面(mian)留下(xia)流星斑等(deng)缺点,构(gou)(gou)成(cheng)滚(gun)(gun)筒(tong)(tong)面(mian)粗糙(cao)度升高(gao),磨损量(liang)不断增大。

4、粘钢、反常磨(mo)损等(deng)

由于轧制异常构成(cheng)辊(gun)面(mian)与轧件之(zhi)间的粘连(lian),轧制工艺参数不合理,同宽辊(gun)消(xiao)耗过大,造成(cheng)辊(gun)面(mian)磨损不均..
