模拟实验研究在攀钢Φ１１５０初轧机上采用连铸板坯切分轧制１２０ｍｍ方坯，为初轧机生产小方坯提供生产依据．充分利用Φ１１５０初轧机的辊身长度，科学地配置孔型，使其既能采用钢锭生产重轨坯，又能利用连铸坯切分轧制１２０ｍｍ方坯，满足现厂生产，证明采用初轧机切分轧制小方坯可行性 Simulated experimental study In the Panzhihua Φ1150 initial rolling mill continuous casting slab using 120mm billet, for the production of billet mill production basis. Take full advantage of the Φ1150 initial mill roll length, the scientific configuration of the hole, so that it can not only the production of heavy rail slab billet, but also the use of continuous casting billet 120mm billet, to meet the factory production, the use of the first rolling mill Cutting billet feasibility of rolling
