擠干輥質(zhì)量不理想、蒸汽壓力偏低。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)極易發(fā)生過酸洗，直接影響到帶鋼表面大面積發(fā)黑現(xiàn)象?？赡芷髽I(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)必須時(shí)間更換擠干輥。而為了能夠提高烘干環(huán)節(jié)的質(zhì)量水平，就必須保證蒸汽供應(yīng)壓力達(dá)到嚴(yán)格的行業(yè)要求。像某地區(qū)企業(yè)，采用二級(jí)烘干、一級(jí)熱風(fēng)、二級(jí)冷風(fēng)進(jìn)行酸洗烘干操作，面對(duì)較低的蒸汽壓力，不僅無法保證充足的熱風(fēng)溫度，而且也很難作帶鋼表面多余的漂洗水進(jìn)行多方面烘干。 </p><p

我廠酸軋車間由于產(chǎn)量大，任務(wù)重，并且是冷軋板的第- -道工序,如果不是軋冷硬卷的話，可以靠后幾道工序改善板形質(zhì)量，因而沒有使用破磷機(jī),帶鋼邊浪嚴(yán)重，擠干輥被劃得遍體鱗傷。擠干輥在服役過程中,整個(gè)輥身受到周期性載荷作用。</p><div style="width:100%;text-align: center;"><img

style="text-indent:25px">擠干輥調(diào)質(zhì)處理的組織和性能。鍛件冷軋工作輥的比較終熱處理形式通常是感應(yīng)加熱淬火。在感應(yīng)加熱淬火時(shí)，加熱速度很快，奧氏體化時(shí)間較短，對(duì)淬火組織要求很高。所以，必須做好組織準(zhǔn)備才能得到理想的淬火組織。大多數(shù)鍛件冷軋工作輥制造者是采用調(diào)質(zhì)熱處理，以回火索氏體作為預(yù)備組織，這時(shí)綜合力學(xué)性能十分優(yōu)良。調(diào)質(zhì)處理即淬火+高溫回火，淬火馬氏體在高溫回火時(shí)充分分解，析出顆粒狀碳化物，組織為細(xì)的回火索氏體。這種回火索氏體是很好的預(yù)備組織，在感應(yīng)加熱的短時(shí)奧氏體化條件下，它可以迅速轉(zhuǎn)變?yōu)榫鶆驃W氏體，同時(shí)細(xì)顆粒狀碳化物在加熱時(shí)又有一定的穩(wěn)定性，保留部分未溶碳化物，提高耐磨性。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。上海擠干輥生產(chǎn)線</p><p style="text-indent:25px">擠干輥采用不同的擬合方法，既可滿足要求，又可減少機(jī)床程序運(yùn)算量，盡可能提高工作效率。上海擠干輥生產(chǎn)線</p><p style="text-indent:25px">每天印刷結(jié)束后，應(yīng)認(rèn)真清洗擠干輥，將其表面油墨清洗干凈，清洗時(shí)要選用專業(yè)的清洗劑，對(duì)擠干輥有腐蝕作用的溶劑是不能使用的，還要檢查擠干輥表面是否有紙毛、紙粉等停留，如果有應(yīng)用布擦拭。清洗時(shí)一定要清洗干凈，否則長此以往，表面會(huì)出現(xiàn)凹凸不平、變形和龜裂等問題，會(huì)影響印品質(zhì)量和印刷速度。待擠干輥清洗干凈后，應(yīng)用塑料薄膜把膠體封包起來，放置在輥架上，放置時(shí)為避免膠體受損傷，不能放置在靠墻周圍，膠體要分開放，不能堆放在一起。上海擠干輥生產(chǎn)線</p></p><br
