style="text-indent:25px">擠干輥用于除去帶鋼表面多余的液體，在酸洗、鍍鋅彩涂等車間都有使用，一般都成對數(shù)組使用。它可以防止堿洗/酸洗槽中的液體被帶入下-一個水槽中，所經(jīng)過的水槽中的液體濃度依次降低，以便于對各水槽的濃度進行控制。由于擠千輥在酸洗、鍍鋅等車間都使大批使用，一般都多達28根，因此也是占用一筆不小的資金，因而擠干輥使用得恰當與否，也是影響成本的一-大要素，現(xiàn)就酸洗車間的擠干輥使用中出現(xiàn)的問題作下分析。擠干輥平時使用要注意保養(yǎng)的。上海擠干輥價格擠干輥跑偏調(diào)整：輸送機開動后，運輸帶之所以跑偏，主要是跟運輸帶相關(guān)聯(lián)的部位。</p><div

m與0337mm之間時，每次下線都可以磨削，重復(fù)使用。到337m以下，如果輥子內(nèi)部的鐵芯沒有損壞，就可以將涂層扒掉，重新上膠，再次使用.擠千輥在使用中出現(xiàn)的各種缺陷1)制造工藝缺陷及處理辦法橡膠成分的影響:在使用中，我廠1酸軋車間曾有20多根新掛膠的擠干輥，同時發(fā)生了大面積地掉肉現(xiàn)象。這批擠干輥要求橡膠耐酸，氯離子濃度為200g/1,鐵離子濃度為130 g/l,溫度為95C.如此大規(guī)模的不正常損壞，只能是制造環(huán)節(jié)出了問題。我們及時與廠家溝通，發(fā)現(xiàn)原來廠'家在生產(chǎn)過程中，將兩批不同成分的橡膠弄混了，正是由于橡膠成分不符合我廠的使用環(huán)境，才造成了擠干輥大批損壞。</p><p style="text-indent:25px">擠干輥工藝采用不同的擬合方法，既可滿足要求，又可減少機床程序運算量，盡可能提高工作效率。為了使各段之間圓滑過渡，可以在段端點附近設(shè)計適當曲率的過渡曲線。但要注意過渡曲線要設(shè)計在AB、CD這些軋制工藝的過渡段，減少對BC、DE這些工作段。DE與EA段的過渡段可以設(shè)計在DE段的A點附近。用數(shù)控車削方法，可以實現(xiàn)對大型周期冷軋輥孔型的高效率加工，需要采取的措施有：（1）加工孔型采用弧形段面的徑向進給路徑，減少運算和累積誤差。（2）對各段孔型進行曲線優(yōu)化，減小刀架運動沖擊和進給電機功率。（3）選用合適的曲線擬合方法，提高機床工作效率。新鑄制的擠干輥內(nèi)部結(jié)構(gòu)由于不穩(wěn)定。</p><div

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，提出改進辦法，如要求改進橡膠成分、增加涂層韌性等，共同改進制造工藝，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,帶鋼邊浪嚴重，擠干輥被劃得遍體鱗傷。擠干輥經(jīng)特殊定性工藝，以滿足不同工藝的需要。上海擠干輥廠家定制</p><p style="text-indent:25px">對擠干輥存在缺陷的原因分析，并采取相應(yīng)的措施，在很大程度上降低了成本。上海擠干輥廠家定制</p><p style="text-indent:25px">擠干輥使用一段時間后，磨削加工輥面時，氣孔暴露出來。表現(xiàn)在輥上就是發(fā)現(xiàn)有四壁光滑，形狀不規(guī)則的輥身缺肉現(xiàn)象。側(cè)面橡膠開裂:有的擠干輥在使用中輥身完好，輥子直徑還很大，遠遠不到掛膠的尺寸，但輥子側(cè)端面有局部位置橡膠開裂，露出鐵芯。由于端面涂層只有5m厚，涂層太薄，并且輥子側(cè)端面的橡膠成分與輥身橡膠成分不同，硬度比輥身硬度大。材質(zhì)不同，在液壓缸壓力的擠壓下造成開裂，見照片一。這種情況下只能掛膠。正常情況下，擠干輥應(yīng)保證我們用到比較小尺寸再掛膠時，側(cè)端面的涂層始終完好。上海擠干輥廠家定制</p></p><br
