    連鑄圓管坯熱送熱裝軋管的實(shí)踐及問題探討

    Practice of Hot-conveyance/Hot-charging of CC Round Billet to Pipe-rolling Process and Discussion on Related Issues

    • 摘要: 介紹了連鑄圓管坯熱送熱裝軋管工藝和設(shè)備，以及熱送熱裝軋管的試驗(yàn)過程，并由此提出了值得研究和探討的問題。分析認(rèn)為：連鑄圓管坯熱送熱裝軋管工藝節(jié)能效果顯著，適用于品種單一或少品種（1～4種）、年產(chǎn)量≥25萬t的軋管機(jī)組。在當(dāng)前我國鋼鐵工業(yè)產(chǎn)業(yè)升級和實(shí)現(xiàn)可持續(xù)發(fā)展、防止低水平重復(fù)建設(shè)的形勢下，研究和應(yīng)用連鑄圓管坯熱送熱裝軋管工藝，對淘汰傳統(tǒng)落后工藝具有借鑒意義。

       

      Abstract: Detailed in the article are the process of hot-conveyance/hot-charging of the CC round billet to piperolling and related equipment as well as the trial activities of the said process.Accordingly relevant issues need to be studied and discussed are put forward here.The analysis reveals that the round CC billet hot-conveyance/hot-charging process features remarkable energy-saving efficiency, being applicable to pipe-rolling mills with single pipe type or few pipe types(one to four types)and a yearly capacity ≥ 250, 000 tons.The author regards that research and application of the technology of hot-conveyance/hot-charging of CC round billet to pipe-rolling process are worth using as reference for eliminating relevant conventional backward technologies, particularly in the present situation of the domestic steel industry involving cutting excessive capacity, upgrading, realizing sustainable development, and preventing repeated low-level constuctions.
