Embodiment approach

[0022] Preferably, as figure 1 As shown, the slag cleaning device further includes a walking device arranged on the body 4 to facilitate the movement of the slag cleaning device during the working process, for example, to move to a working position to perform slag cleaning operations, or to complete slag cleaning Leave the work position after the job. The walking device may be various walking devices known in the art, such as a sliding walking device, a rolling walking device, etc. As a specific implementation, the walking device includes wheels 15 driven by a motor 13.

[0023] The above-mentioned motors 11 and 13 can be various motors known in the art, such as variable speed motors. A protective cover 12 may be provided above the motors 11 and 13 to prevent the thermal radiation of the molten steel vacuum treatment insertion tube 14 and the scattered steel slag from damaging the motors 11 and 13.

[0024] The present invention also provides a slag removal method for the vacuum t...

Abstract

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 ofa 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 present invention relates to a slag cleaning device and method, and more specifically, to a slag cleaning device and method for vacuum processing 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. The usual practice is to insert the vacuum treatment insertion tube of the molten steel vacuum treatment device into the molten steel to vacuum the molten steel. The vacuum treatment insert tube will adhere to the steel slag after it contacts the molten steel. The excessively bonded steel slag will affect the vacuum processing operation. The steel slag adhered to the vacuum treatment insert tube must be removed in time. [0003] The existing slag cleaning device is usually provided with a plurality of stationary long blades. By pressing the vacuum treatment insertion tube against the plurality of stationary long blades, the bonded steel slag ...
