絞線(xian)(xian)(xian)中單線(xian)(xian)(xian)起(qi)槽(cao)或(huo)表面(mian)(mian)缺陷產生(sheng)原因：單線(xian)(xian)(xian)表面(mian)(mian)的麻坑，斑疤、三角裂(lie)，夾渣等缺陷，主要是(shi)材料帶(dai)來的，當然線(xian)(xian)(xian)芯表面(mian)(mian)有(you)碎裂(lie)現象，也不排除拉線(xian)(xian)(xian)模孔(kong)型不合理而產生(sheng)的，此時需具體情況具體分析(xi)，而線(xian)(xian)(xian)芯表面(mian)(mian)起(qi)槽(cao)呈(cheng)連(lian)續(xu)性，一般都(dou)是(shi)拉線(xian)(xian)(xian)時造(zao)成的，拉線(xian)(xian)(xian)潤滑條(tiao)件惡化(hua)，表面(mian)(mian)粘鋁而造(zao)成，不呈(cheng)連(lian)續(xu)性的起(qi)槽(cao)，有(you)可能(neng)是(shi)絞線(xian)(xian)(xian)壓(ya)模粘異物所(suo)致。

消除(chu)(chu)辦法：對于拉(la)(la)線(xian)時(shi)(shi)(shi)鋁線(xian)起槽，應首先檢(jian)(jian)查(cha)拉(la)(la)線(xian)潤滑效果是否(fou)能滿足拉(la)(la)線(xian)的要求(qiu)，需及時(shi)(shi)(shi)更換(huan)潤滑油，更換(huan)拉(la)(la)線(xian)模(mo)具，或排除(chu)(chu)粘在線(xian)模(mo)上的雜(za)物，認真(zhen)檢(jian)(jian)查(cha)進線(xian)，對不合格的進線(xian)要及時(shi)(shi)(shi)排除(chu)(chu)，同時(shi)(shi)(shi)檢(jian)(jian)查(cha)緊壓線(xian)模(mo)有無損傷，有無雜(za)物，要及時(shi)(shi)(shi)修理和更換(huan)，
