目前國內軸承(cheng)鋼(gang)管(guan)(guan)的生(sheng)(sheng)產工藝(yi)未發生(sheng)(sheng)實質性的變化,常見(jian)的軸承(cheng)鋼(gang)管(guan)(guan)生(sheng)(sheng)產方法主要(yao)有兩(liang)(liang)種(zhong):(1)穿(chuan)孔(kong)(kong)+冷(leng)軋(拔)工藝(yi);(2)穿(chuan)孔(kong)(kong)+三輥軋管(guan)(guan)(或二輥軋管(guan)(guan))+定(ding)徑(張減機)或+冷(leng)軋(拔)工藝(yi)。在這兩(liang)(liang)種(zhong)工藝(yi)中,坯(pi)料采用軋制(zhi)坯(pi)或連鑄坯(pi),鋼(gang)管(guan)(guan)(從(cong)坯(pi)料到成品)的壓縮比應(ying)大于15。


  其中,以穿孔+冷軋(拔)工藝生(sheng)產(chan)的軸承(cheng)鋼(gang)管,多為中小直(zhi)徑精密的軸承(cheng)管,生(sheng)產(chan)規格(ge)為Φ(14~120)mm×(2~15)mm,鋼(gang)管材(cai)質(zhi)為GCr15或GCr15SiMn。該(gai)生(sheng)產(chan)工藝相對簡(jian)單,裝(zhuang)備少,流(liu)程短,投資少,產(chan)量低。


  以穿孔+三輥(gun)(gun)軋(ya)(ya)管(guan)(guan)(或(huo)二輥(gun)(gun)軋(ya)(ya)管(guan)(guan))+定徑(張(zhang)減徑)或(huo)+冷軋(ya)(ya)(拔)工(gong)(gong)藝生產的(de)(de)鋼(gang)管(guan)(guan),是(shi)目前國際上(shang)主流(liu)的(de)(de)生產軸(zhou)承(cheng)(cheng)鋼(gang)管(guan)(guan)的(de)(de)熱(re)軋(ya)(ya)方法,可實現控溫控軋(ya)(ya)。其(qi)生產規格為(wei)(wei)(wei)(wei)Φ(48~200)mmx(5~30)mmm,多為(wei)(wei)(wei)(wei)規格范圍較寬泛(fan)的(de)(de)軸(zhou)承(cheng)(cheng)鋼(gang)管(guan)(guan),鋼(gang)管(guan)(guan)材質為(wei)(wei)(wei)(wei)具備(bei)不同淬透性的(de)(de)高碳鉻軸(zhou)承(cheng)(cheng)鋼(gang)。該生產工(gong)(gong)藝復雜,裝備(bei)多,流(liu)程長,投(tou)資大,但產量(liang)高。目前,三輥(gun)(gun)軋(ya)(ya)管(guan)(guan)機被(bei)公認為(wei)(wei)(wei)(wei)最(zui)適(shi)宜的(de)(de)軸(zhou)承(cheng)(cheng)鋼(gang)管(guan)(guan)和精密中厚壁(bi)鋼(gang)管(guan)(guan)生產機組。
