（1）生產(chǎn)效率高：用傳統(tǒng)的方法生產(chǎn)一根內(nèi)徑420毫米，12米長的缸筒需154小時(shí)，用冷拔方法生產(chǎn)只需4分鐘。 </p> <p> （2）成品率高：由于鏜孔的滾壓頭兼起導(dǎo)向作用，在切削過程中，毛坯管由于自重產(chǎn)生撓度，致使?jié)L壓頭和鏜刀走偏，造成廢品。成品率只能達(dá)到60%左右，而用冷拔方法生產(chǎn)，成品率可達(dá)95%以上。 </p> <p> （3）金屬利用率高：用傳統(tǒng)的鏜孔方法制造缸體，金屬利用率只有50-70%。用拉拔方法生產(chǎn)時(shí)，金屬不但不被切削成鐵末，反而可以得到30%的延伸，金屬利用率可達(dá)95%。 </p> <p> （4）能改善成品管金屬的機(jī)械性能：用拉拔方法生產(chǎn)，使毛坯得到30%以上的塑性變形，由于加工硬化而使成品管金屬的強(qiáng)度限大為提高。一般在成品管內(nèi)層強(qiáng)度限提高達(dá)60%。高精度冷拔管是用無縫熱軋鋼管、直縫焊管為坯料，經(jīng)過化學(xué)處理后在**冷拔機(jī)上，通過特種變形原理設(shè)計(jì)的模具進(jìn)行拉拔，生產(chǎn)出高精度管。其尺寸精度達(dá)H10～H8，直線度達(dá)0.35～0.5mm/m，表面粗糙度達(dá)Ra1.6-0.4。冷拔方鋼要如何存放堆積？河南冷拔方鋼報(bào)價(jià)</p><p style="text-indent:25px">康弘機(jī)械的冷拔鋼產(chǎn)品經(jīng)過合格檢驗(yàn)。新鄉(xiāng)冷拔鋼哪家便宜</p><p> 冷拔圓鋼外表面光滑，可塑性強(qiáng)，延展性能好，易于加工。冷拔圓鋼相比于市面上的其它鋼筋種類的區(qū)別主要體現(xiàn)在三個(gè)方面，通過以下內(nèi)容進(jìn)行說明：<span style="font-size:12px;">1、外型不一樣，圓鋼外型光圓，無紋無肋，其它鋼筋表面外型有刻紋或有肋，這樣就造成圓鋼與混凝土的粘結(jié)力小，而其它鋼筋與混凝土的粘結(jié)力大。</span><span style="font-size:12px;">2、成份不一樣，圓鋼(一級(jí)鋼)屬于普通低碳鋼，其它鋼筋多為合金鋼。</span><span style="font-size:12px;">3、強(qiáng)度不一樣，冷拔圓鋼強(qiáng)度低，其它鋼強(qiáng)度高，即直徑大小相同的圓鋼與其它鋼筋相比，圓鋼所能承受的拉力要比其它鋼筋小，但圓鋼的塑性比其它鋼筋強(qiáng)，即圓鋼在被拉斷前有較大的變形,而其它鋼筋在被拉斷前的變形要小得多。</span> 新鄉(xiāng)冷拔鋼哪家便宜</p><p
