The industrial robot 20 is mainly used for driving the slag dragging device 30 to move, and the slag dragging function and the slag removing function are achieved. Specifically, the industrial robot 20 is installed on the side of the aluminum ingot casting machine 10, and includes a controller 22 and a robot 21, and the controller 22 controls the operation of the robot 21.

The slag salvaging frame body 33 is a strip-shaped structure and is mainly used for installing a slag salvaging blade 39. The slag salvaging frame body 33 is fixedly connected with the other end of the connecting arm 31. The connecting arm 31 can be connected to the slag salvaging bracket body 33 through a bolt and a stop ring. In other embodiments, the connecting arm 31 may be welded directly to the slag holder body 33.
