The invention embodiment provides a rough rolling and descaling control method used to improve the descaling effect. The method comprises the steps of obtaining control parameters including codes of a steel family to which a slab to be rolled roughly and descaled belongs, a band steel target width, a band steel target thickness and a preset rough rolling mode; determining a target descaling mark of descaling equipment in the rough rolling and descaling process based on the control parameters, the descaling mark represents the working state of the descaling equipment; controlling the descaling equipment to descale the slab to be rolled roughly and descaled based on the target descaling mark. 本发明实施例提供了种粗轧除鳞的控制方法，用于提高除鳞效果。所述方法包括：获得控制参数，所述控制参数包括待粗轧除鳞的板坯所归属的钢种族代码、带钢目标宽度、带钢目标厚度和预先设置的粗轧轧制模式；基于所述控制参数，确定粗轧除鳞过程中除鳞设备的目标除鳞标志，除鳞标志表示所述除鳞设备的工作状态；基于所述目标除鳞标志控制所述除鳞设备对所述待粗轧除鳞的板坯除鳞。
