精密鋼管是一種通過冷拔或熱軋處理后的一種高精密的鋼管材料。由于精密鋼管內外壁無氧化層、承受高壓無泄漏、高精度、高光潔度、冷彎不變形、擴口、壓扁無裂縫等優點,所以主要用來生產氣動或液壓 元件的產品,如氣缸或油缸,可以是無縫管,也有焊接管。 熱軋精密鋼管用(yong)連(lian)鑄圓(yuan)管坯(pi)板(ban)坯(pi)或初軋(ya)(ya)(ya)(ya)板(ban)坯(pi)作原料,經步(bu)進(jin)式加(jia)熱(re)(re)爐(lu)加(jia)熱(re)(re),高壓(ya)水除鱗后(hou)(hou)進(jin)入粗軋(ya)(ya)(ya)(ya)機,粗軋(ya)(ya)(ya)(ya)料經切(qie)(qie)(qie)頭、尾(wei)(wei)、再進(jin)入精軋(ya)(ya)(ya)(ya)機,實(shi)施(shi)計算機 控制(zhi)軋(ya)(ya)(ya)(ya)制(zhi),終軋(ya)(ya)(ya)(ya)后(hou)(hou)即(ji)經過(guo)層流冷(leng)卻和卷(juan)(juan)取(qu)機卷(juan)(juan)取(qu)、成為(wei)直(zhi)發卷(juan)(juan)。直(zhi)發卷(juan)(juan)的(de)頭、尾(wei)(wei)往往呈舌狀及魚尾(wei)(wei)狀,厚度(du)、 寬度(du)精度(du)較差,邊部常存在浪形、折邊、塔形等(deng)缺陷。其(qi)卷(juan)(juan)重較重、鋼(gang)卷(juan)(juan)內(nei)徑為(wei)760mm。將(jiang)直(zhi)發卷(juan)(juan)經切(qie)(qie)(qie)頭、 切(qie)(qie)(qie)尾(wei)(wei)、切(qie)(qie)(qie)邊及多道次的(de)矯直(zhi)、平整(zheng)(zheng)等(deng)精整(zheng)(zheng)線處理后(hou)(hou),再切(qie)(qie)(qie)板(ban)或重卷(juan)(juan),即(ji)成為(wei):熱(re)(re)軋(ya)(ya)(ya)(ya)鋼(gang)板(ban)、平整(zheng)(zheng)熱(re)(re)軋(ya)(ya)(ya)(ya)鋼(gang)卷(juan)(juan)、縱切(qie)(qie)(qie)帶等(deng)產品。熱(re)(re)軋(ya)(ya)(ya)(ya)精整(zheng)(zheng)卷(juan)(juan)若經酸洗去(qu)除氧(yang)化皮并涂油后(hou)(hou)即(ji)成熱(re)(re)軋(ya)(ya)(ya)(ya)酸洗板(ban)卷(juan)(juan)。
