style="text-indent:25px">兩種鋼管工藝流程詳解冷拔鋼管用熱軋鋼卷為原料，經(jīng)酸洗去除氧化皮后進(jìn)行冷連軋，其成品為軋硬卷，由于連續(xù)冷變形引起的冷作硬化使軋硬卷的強(qiáng)度、硬度上升、韌塑指標(biāo)下降，因此沖壓性能將惡化，只能用于簡單變形的零件。軋硬卷可作為熱鍍鋅廠的原料，因為熱鍍鋅機(jī)組均設(shè)置有退火線。軋硬卷重一般在6~13.5噸，鋼卷內(nèi)徑為610mm。一般冷連軋板、卷均應(yīng)經(jīng)過連續(xù)退火（CAPL機(jī)組）或罩式爐退火消除冷作硬化及軋制應(yīng)力，達(dá)到相應(yīng)標(biāo)準(zhǔn)規(guī)定的力學(xué)性能指標(biāo)。冷拔鋼要按照正確步驟進(jìn)行加工。新鄉(xiāng)冷拔鋼銷售</p><p
