Embodiment approach
[0022] Preferably, as figure 1 As shown, the slag removal device also includes a walking device arranged on the vehicle body 4, so as to facilitate the movement of the slag removal device during the working process, for example, to move to the working position for slag removal operation, or to complete the slag removal Leave the work place after work. The walking device can be various walking devices known in the art, such as a sliding running device, a rolling running device, etc. As a specific implementation, the running device includes wheels 15 driven by a motor 13 .
[0023] The motors 11 and 13 mentioned above can adopt various motors known in the art, such as variable speed motors. A protective cover 12 may be provided above the motors 11, 13 to prevent the motors 11, 13 from being damaged by heat radiation from the molten steel vacuum treatment insertion pipe 14 and scattered steel slag.
[0024] The present invention also provides a slag removal method for vacuum tr...

The invention provides a slag removing device used for a molten steel vacuum treatment insert tube (14), wherein the slag removing device comprises a car body (4), two pairs of shovel blades (71,72,73, and 74) and a drive device. A pair of shovel blades (71 and 72) is oppositely arranged along the lateral direction (A) of the car body, and the other pair of shovel blades (73 and74) is oppositely arranged along the longitudinal direction (B) of the car body, so that the two pairs of shovel blades can form a slag removing space (20) suitable for the molten steel vacuum treatment insert tube to insert; the driving device drives the shovel blades to vibrate up and down along the height direction (C) of the car body. The invention also provides a method for removing slags by the slag removing device. Even the steel slags with high cohesional strength can be easily removed by using the slag removing device and method; moreover, since the slag removing speed is high, the working efficiency of a vacuum treatment device can be increased; in addition, as the motion path of the shovel blades of the slag removing device is relatively stable, the vacuum treatment insert tube can not be damaged.
Description
technical field [0001] The invention relates to a slag removal device and method, more specifically, to a slag removal device and method for vacuum treatment insertion pipes of molten steel. Background technique [0002] In order to improve the purity of the material, the molten steel needs to be vacuum treated before casting. A common practice is to insert a vacuum treatment insertion tube of a molten steel vacuum treatment device into the molten steel to perform vacuum treatment on the molten steel. When the vacuum treatment insertion tube contacts molten steel, steel slag will be bonded. Excessively bonded steel slag will affect the vacuum treatment operation, and the steel slag bonded on the vacuum treatment insertion tube must be removed in time. [0003] Existing slag cleaning devices are usually provided with a plurality of stationary elongated blades. The bonded slag is stripped off the vacuum treatment insert by pressing the vacuum treatment insert against the plu...
