淮钢炼钢厂电炉车间主要产品为150 mm×150 mm连铸方坯,铸坯定尺标准要求公差范围0~80 mm,通过精心控制,目前电炉连铸坯公差基本控制在0~30 mm,既符合标准要求又减少了轧制切头切尾产生量。电炉连铸工段结合生产实际和轧钢具体需求制定了《连铸坯定尺控制规定》,要求生产班火切工测量在线热坯长度、白班管理人员复测坯库冷坯长度进行校核,逐步摸索出不同钢种冷却收缩率,据此确定不同钢种热坯剪切长度。在热坯
The main product of Huai Steel Steel Furnace EAF workshop is 150 mm × 150 mm continuous casting billet. The slab size standard requires the tolerance range of 0-80 mm. With careful control, the tolerance of the continuous casting furnace of the electric furnace is basically controlled within 0-30 mm , Both in line with the standard requirements and reduce the amount of rolling cut tail. Electric furnace continuous casting section with the actual production and rolling the specific needs of the development of the “continuous casting slab length control requirements”, requiring fire class production line measuring the length of the online hot billet, day shift managers to re-measure the length of the blank library blank check, and gradually Sift out the cooling shrinkage of different types of steel, and thus determine the different types of steel billet shear length. In the hot billet
