style="text-indent:25px">如果擠干輥裂口或劃傷比較深，已露出鐵芯，這種輥不能再上線使用，酸液會(huì)從裂口進(jìn)入，腐蝕鐵芯，致使整個(gè)擠干輥折斷在酸槽中。這種輥?zhàn)蛹词怪睆竭€很大，也要直接掛膠，否則鐵芯損壞，不能重復(fù)使用，只好增加新輥補(bǔ)償備件，得不償失。因此裂口或劃傷是否深至輥芯，決定輥?zhàn)幽ハ鬟€是掛膠，而磨削與掛膠費(fèi)用相差很多，又直接影響到成本。裂口或劃傷寬度一般都很窄,其深度*憑目測(cè)很難判斷，并且切口方向不是垂直于輥面，多為斜切口。從帶鋼表面酸的存留程度進(jìn)行分析可以發(fā)現(xiàn)，與擠干輥的擠干效果有著必然的聯(lián)系。基于較多表面酸殘留，就會(huì)易發(fā)生過酸洗，直接影響到帶鋼表面大面積發(fā)黑現(xiàn)象。可能企業(yè)在短時(shí)間內(nèi)沒有操作酸洗，那么經(jīng)過時(shí)間的推移，也會(huì)引發(fā)銹蝕的現(xiàn)象?；谠O(shè)計(jì)角度下，一般的擠干輥完成4～4．5 萬噸生產(chǎn)工作后即可淘汰。但是大多數(shù)企業(yè)違背了這一原則，往往將其進(jìn)行超過1800t 的生產(chǎn)量，**終對(duì)其造成了嚴(yán)重的損壞，此時(shí)必須立即更換擠干輥。擠干輥跑偏調(diào)整：輸送機(jī)開動(dòng)后，運(yùn)輸帶之所以跑偏，主要是跟運(yùn)輸帶相關(guān)聯(lián)的部位。</p><div
