style="text-indent:25px">關(guān)于擠干輥方面的資料很少，還沒有看到過相關(guān)的書籍，因而無從借鑒，采用何種修復(fù)手段，只能憑經(jīng)驗判斷。輥面缺陷的處理辦法1)經(jīng)常與廠家聯(lián)系，發(fā)現(xiàn)問題及時與廠家溝通。如果發(fā)現(xiàn)產(chǎn)品質(zhì)量問題，如大面積掉塊、裂紋等，與廠家結(jié)合，返修輥子，提出改進(jìn)辦法，如要求改進(jìn)橡膠成分、增加涂層韌性等，共同改進(jìn)制造工藝，解決產(chǎn)品質(zhì)量問題。2) 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,帶鋼邊浪嚴(yán)重，擠干輥被劃得遍體鱗傷。上海擠干輥行業(yè)前景廢舊擠干輥在運送加工澆鑄的運輸過程中，為保持輥芯不偏芯、不彎曲，切勿隨意亂扔亂放亂壓或重壓。</p><div

style="text-indent:25px">擠干輥進(jìn)程刀具進(jìn)給加速度a=2s/t2，式中s為刀具進(jìn)給距離，即孔型工作段兩端點處工件的回轉(zhuǎn)半徑之差，也即孔型半徑之差（注：此處計算忽略了孔型圓弧中心相對于輥縫中心的變化值及輥縫）。代入數(shù)值，計算出刀具以比較小相同數(shù)值的勻加速和勻減速進(jìn)給加工AB段孔型時的加速度值為a1=2.44m/s2。由此做出AB段孔型的變化曲線（見圖6），結(jié)果為二次曲線。由于AB段實際只是管坯送進(jìn)的入口位置，對形狀要求不高，因此該曲線可滿足功能要求，且符合加工過程中沖擊比較小的優(yōu)化要求。</p><p> 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?；谳^多表面酸殘留，就會極易發(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)在短時間內(nèi)沒有操作酸洗，那么經(jīng)過時間的推移，也會引發(fā)銹蝕的現(xiàn)象。基于設(shè)計角度下，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，**終對其造成了嚴(yán)重的損壞，此時必須時間更換擠干輥。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)，采用二級烘干、一級熱風(fēng)、二級冷風(fēng)進(jìn)行酸洗烘干操作，面對較低的蒸汽壓力，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。擠干輥損壞，只能是制造環(huán)節(jié)出了問題。</p><div

也可以減少膠輥膠圈的損壞和損傷,這也是棉紗質(zhì)量保持穩(wěn)定、減少棉紗疵點的重點。牽伸和卷繞部件隨著每天清潔次數(shù)的增加,飛花附入牽伸和卷繞部件的幾率降低,膠輥膠圈纏繞幾率下降,膠輥膠圈損傷、損壞的程度明顯下降;隨著紡紗號數(shù)的增加和棉紗質(zhì)量要求提高,膠輥膠圈纏繞、損傷、損壞的程度更加明顯,增加牽伸和卷繞部件的清潔頻次是行之有效的。在生產(chǎn)普通號數(shù)棉紗時,牽伸和卷繞部件每班清潔兩次膠輥膠圈的損傷、損壞只有牽伸和卷繞部件每天清潔一次的10%~20%。實踐證明,牽伸和卷繞部件合理的清潔頻次和適當(dāng)增加清潔頻次,是保證膠輥膠紡紗完整的重要環(huán)節(jié)。
