CN101658860A 一种薄板坯连铸连轧生产线 无效 - 驳回

一种薄板坯连铸连轧生产线
摘要：
本发明涉及薄板坯连铸连轧生产线。主要解决现有生产线存在产线刚性强以及生产薄板表面质量差的技术问题。本发明的技术方案为：一种薄板坯连铸连轧生产线，生产线设备布置依次为：连铸机—摆动剪—辊底式隧道炉—除鳞装置—立辊—粗轧机—热卷箱—超快水冷装置—飞剪机—精轧机—层流冷却和超快水冷装置—卷取机。在飞剪机和精轧机之间可设二次除鳞装置。连铸机采用两台双流，两座辊底式隧道式加热炉，通过一台横移机，使2台连铸机的2流并为1流，并与轧线相连。本发明主要用于薄板坯连铸连轧。
摘要（英）：

The invention relates to a sheet billet continuous casting and rolling production line and mainly solves the technical problems of high rigidity and low surface quality of produced sheet billets of the prior production line. The invention adopts a technical scheme that: the sheet billet continuous casting and rolling production line is sequentially provided with the following production line equipment: a continuous casting machine, swinging shears, a roller-hearth tunnel furnace, a descaling unit, a vertical roll, a rough mill, a coil box, a ultrafast water-cooling device, flying shears, a finishing mill, a laminar flow-cooling and ultrafast water-cooling device and a coiling machine, wherein a secondary descaling unit can be arranged between the flying shears and the finishing mill; and the continuous casting machine adopts two double flow roller-hearth tunnel heating furnaces, combines two flows of the two continuous casting machines into one flow through a transverse moving machineand is connected with a rolling line. The invention is mainly used for continuous casting and rolling of sheet billets.
