When the slag removing operation is needed, the piston rod of the reverse-pull oil cylinder 6 is controlled to contract, the bottom support 4 can be driven to reversely overturn opposite to the overturning casting, and when the set angle is reached, the slag remover can be controlled to remove the floating slag in the water drum 5 into the slag groove. By adopting the structural arrangement of the reverse-pull oil cylinder, the acting force during slag skimming is mainly concentrated on one side, namely the rotating shaft, of the bottom support 4 hinged with the overturning support 2, so that the additional pressure generated on the reverse-pull oil cylinder 6 is avoided, the service life of the oil cylinder is greatly prolonged, and the problem that the lifting oil cylinder is damaged due to the fact that the lifting oil cylinder can generate large pressure when a conventional lifting oil cylinder drives a water drum to overturn for a certain angle for skimming is solved. When the pouring needs to be tipped, the reverse pulling oil cylinder 6 is controlled to reset, and then the lifting oil cylinder 3 is controlled to drive the overturning bracket 2 to drive the water drum 5 to integrally overturn and dump, so that the pouring is convenient and fast.

It should be noted that the tilting device is necessary to be divided into a structure for tilting forward and backward to respectively carry out slag skimming and casting, because the lifting cylinder is adopted to turn over the water drum 5 and then slag skimming causes great damage to the cylinder, while the cylinder adopting the reverse-pulling type alone is difficult to realize large-angle turning over of the water drum 5 due to the problems of installation and stroke of the reverse-pulling type cylinder, namely, casting work is difficult to complete.

Besides, in order to facilitate the precise control of the turning angle of the water drum 5 during actual operation, the present embodiment further arranges detection mechanisms for detecting the original angle, the rated turning angle and the maximum turning angle of the tilting bracket 2 on the base 1 or the tilting bracket 2, and arranges detection mechanisms for detecting the original angle, the rated turning angle and the maximum turning angle of the bottom bracket 4 on the base 1 or the tilting bracket 2 or the bottom bracket 4.
