摘　　要：本文详细介绍了特种合金长材开坯轧机的组成、布置及轧机本体结构的几种型式,通过优缺点对比,明确三辊轧机将逐步被淘汰,二辊可逆轧机由于自动化程度高、人工劳动强度低将得到广泛应用。对于120~180 mm方断面坯料,采用二辊可逆移动式轧机作为开坯轧机,更适合产量不高的特种合金长材轧制,轧出的产品精度高、表面质量好。This paper detailly introduce the breakdown mill several pattern in composition,layout and mill body structure for special alloy long product rolling,by contrasting their advantage and disadvantage,confirm that 3-high rolling mill will be sifted out step by step,2-high reversible mill will be used widely due to it's high automation and low labour intensity.For 120~180 mm square billet,adopting 2-high reversible moving mill as breakdown mill,it is suitable for low production special alloy long product rolling,the product size precision is higher,and surface quality is better.
