class="box"><p><p style="text-indent:25px">不銹鋼方管變形造成拉縮與起槽因素：拔制方法：將長芯櫸拔制法與短芯櫸拔制法相比，長芯棒拔制時減輕了不銹鋼方管內(nèi)孔表面的軸向張應力，因此戒輕了拉縮與起槽現(xiàn)象，在變形系數(shù)相同的條件下，短芯櫸拔制有明見的相痕，而長芯掙拔制則無。減徑量：當減徑量較大時，一方面不銹鋼方管在減徑區(qū)內(nèi)處于空拔狀態(tài)，容易失穩(wěn)，使管壁彎曲而加深內(nèi)槽深，另一方面，不銹鋼方管焊管生產(chǎn)，由于在成徑過程中，薄壁部分的壁厚有所增加，不銹鋼方管焊管生產(chǎn)，增加了減壁區(qū)的不均勻變形，也增大了拉縮和起槽。因此，不銹鋼方管焊管生產(chǎn)，在拔制異壁異型管時，應盡量采用較小的減徑量。不銹鋼方管在進行軋制的過程中材質(zhì)比較容易受到各方面的影響。不銹鋼方管焊管生產(chǎn)</p><div
