连铸推广以来,已显示了它的优越性。为了保证连铸的顺利操作和连铸坯质量,连铸坯断面不要小于120mm方。我国的小型线材轧机大都是横列式,使用60～90mm方坯,连铸坯不能直接轧成材。因此,这些轧机需经改造后才能用连铸坯一火成材。改造小型轧机的方式很多,但建设连续小型轧机是改 Since the promotion of continuous casting, it has shown its superiority. In order to ensure the smooth operation of continuous casting and slab quality, continuous casting cross-section not less than 120mm square. China’s small wire rod rolling mill are mostly horizontal type, the use of 60 ~ 90mm billet, continuous casting can not be directly rolled timber. Therefore, these mills need to be reformed before they can use the slab to start a fire. There are many ways to transform a small mill, but the construction of a continuous small mill is a change
