Method for cutting water quenching slag ladle

The invention discloses a method for cutting a water quenching slag ladle; the method is to arrange cutting tools on the left and right sides of the water quenching slag ladle, and then cut the water quenching slag ladle by horizontally moving the cutting tools. A suspending method is used for the working parts of the cutting tools, the cutting tools at the left and right sides are distributed asymmetrically, and inserted in the water quenching slag ladle from the side bottom. The left and the right cutting tools can move synchronously, so as to cut eight openings in a crossed form at one time, and the length of each opening is greater than the semi-diameter of the water quenching slag ladle. The method is simple in operation and facilitates maintenance, and can implement a remote operation in cooperation with a small portable type remote controller, so that the accident potential caused by a close-range manual operation is eliminated, and meanwhile, the dust pollution is reduced, and the requirement of safet
