·不銹鋼角鐵圓法蘭的冷鍛和熱鍛有什么不同點(diǎn)當(dāng)前位置:首頁(yè)>新聞動(dòng)態(tài)不銹鋼角鐵圓法蘭的冷鍛是在低溫鍛造時(shí)，法蘭的尺寸變化很小。角鐵圓法蘭是軸與軸之間相互連接的零件，用于管端之間的連接；也有用在設(shè)備進(jìn)出口上的法蘭，用于兩個(gè)設(shè)備之間的連接，如減速機(jī)法蘭。在700℃以下鍛造，氧(Oxygen)化皮形成少，而且表面無脫碳現(xiàn)象。因此，只要變形能在成形能范圍內(nèi)，角鐵圓法蘭冷鍛容易得到很好的尺寸精度和表面光潔度。只要控制好溫度和潤(rùn)滑冷卻，700℃以下的溫鍛也可以獲得很好的精度。冷模鍛、冷擠壓、冷鐓等塑性加工的統(tǒng)稱。扁鐵圓法蘭指將角鋼或角鐵通過特制的設(shè)備進(jìn)行卷彎，加工后的角鋼仍然保持角鋼的兩條邊垂直為90°，不翻邊。且沒有褶皺。冷鍛是對(duì)物料再結(jié)晶溫度以下的成型加工，是在回復(fù)溫度以下進(jìn)行的鍛造。生產(chǎn)(Produce)中習(xí)慣把不加熱毛坯進(jìn)行的鍛造稱為冷鍛。冷鍛材料大都是室溫下變形抗力較小、塑性較好的鋁及部分合金、銅及部分合金、低碳(C)鋼、中碳鋼、低合金結(jié)構(gòu)鋼。冷鍛件表面質(zhì)量好，尺寸精度（精確度）高，能代替一些切削加工。冷鍛能使金屬?gòu)?qiáng)化，提高法蘭的強(qiáng)度。不銹鋼角鐵圓法蘭冷鍛技術(shù)的發(fā)展主要是開發(fā)高附加值的產(chǎn)品，降低（reduce)生產(chǎn)成本。北京鍍鋅法蘭法蘭，就選無錫雋發(fā)暖通設(shè)備有限公司。</p><div
