鍛制圓(yuan)(yuan)(yuan)鋼(gang)用在一些特殊性能要(yao)(yao)求的配(pei)件(jian)加(jia)(jia)工(gong)(gong)(gong)(gong)上。圓(yuan)(yuan)(yuan)鋼(gang)這三(san)樣加(jia)(jia)工(gong)(gong)(gong)(gong)方式都(dou)比較普遍，應該面都(dou)很廣。熱軋圓(yuan)(yuan)(yuan)鋼(gang)，用在建筑和普通(tong)五金(jin)(jin)配(pei)件(jian)加(jia)(jia)工(gong)(gong)(gong)(gong)方面很常(chang)見(jian)。冷拉圓(yuan)(yuan)(yuan)鋼(gang)(不(bu)知(zhi)道指的是不(bu)能冷撥(bo)(bo)圓(yuan)(yuan)(yuan)鋼(gang)。但我按冷撥(bo)(bo)圓(yuan)(yuan)(yuan)鋼(gang)理解。)主要(yao)(yao)也是應用在五金(jin)(jin)配(pei)件(jian)加(jia)(jia)工(gong)(gong)(gong)(gong)生產(chan)方面。如合(he)頁軸芯(xin)或(huo)其它對表面和直(zhi)徑準度有要(yao)(yao)求的生產(chan)加(jia)(jia)工(gong)(gong)(gong)(gong)場合(he)。

　　圓(yuan)(yuan)鋼(gang)分為熱軋、鍛制和冷(leng)拉三種。熱軋圓(yuan)(yuan)鋼(gang)的規格為5.5-250毫米。其中：5.5-25毫米的小圓(yuan)(yuan)鋼(gang)大多以直(zhi)條成(cheng)捆的供(gong)應(ying)，常用作鋼(gang)筋、螺栓(shuan)及各種機械零(ling)件;大于(yu)25毫米的圓(yuan)(yuan)鋼(gang)，主要用于(yu)制造機械零(ling)件、無縫鋼(gang)管(guan)的管(guan)坯等(deng)。
