Description

Technical Field

[0001] The utility model belongs to the technical field of aluminum casting and rolling mills, in particular to a slag removal device for aluminum casting and rolling mills. Background Art

[0002] An aluminum casting mill casts molten aluminum into 6-10mm cast-rolled plates through a series of refining, filtering, cooling, and rolling processes. The molten aluminum cools and solidifies on the rolls, and then is hot-rolled into shape. The aluminum casting mill primarily consists of a static furnace, an automatic liquid level control system, a degassing tank, a filtration system, and casting rolls. The casting rolls are a core component, with circulating cooling water flowing through them to cool the molten aluminum. When the aluminum casting mill operates for extended periods, a large amount of melt debris is generated at the bottom. Any debris that falls must be cleaned promptly to prevent it from adhering to the rolls after cooling, making cleanup more difficult.

[0003] In contrast, the Chinese patent with announcement number CN207238760U discloses a slag removal device for an aluminum casting rolling mill, comprising an aluminum casting rolling mill, a slag removal shaft and a flywheel, wherein a motor is provided above the front surface of the aluminum casting rolling mill, a guide roller is provided below the motor, a cooler is provided at the middle position of the left surface of the aluminum casting rolling mill, and a regulator is provided at the lower left side of the aluminum casting rolling mill; a slag removal shaft is provided on the slag removal device in the aluminum casting rolling mill, when the upper casting roll and the lower casting roll are hot-rolled with each other, excess melt will be introduced into the slag collection box through the slag guide plate, so that the waste slag is effectively collected, when the collected waste slag is too much, the waste slag in the collection box is broken up by the rotation of the slag removal shaft, which is convenient for the brush to collect the waste slag, thereby reducing the situation where the waste slag adheres to the machine body, and a fan is provided on the slag removal device in the aluminum casting rolling mill, and when the brush is cleaning the waste slag, the airflow of the fan can effectively reduce the temperature of the waste slag surface.

[0004] However, the above patent cannot remove the waste slag at the transition point due to the fixed axis, the slag removal is not thorough, and there is only one-way slag removal, which easily leaves residue at the tail. Therefore, a new device needs to be designed. Utility Model Content
