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 120~180mm 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.
