Slag stopping bar feeding device

Abstract

The invention discloses a slag stopping bar feeding device which is applied to a slag stopping bar. A circular ring is welded on the thick end of the slag stopping bar. The slag stopping bar feeding device comprises a slag stopping rod, a guide wheel and a supporting frame, wherein one end of the slag stopping rod is provided with a hook, and the circular ring is arranged on the hook in a sleeving mode and used for connecting the slag stopping bar with the slag stopping rod; the guide wheel is in sliding connection with the slag stopping rod and used for moving the slag stopping rod; and the supporting frame is connected with the guide wheel, and the guide wheel can swing on the supporting frame to drive the slag stopping rod to swing. The device solves the technical problems of complicated slag stopping feeding operation, easy slag stopping failure and low success rate in the prior art. The device has the advantages that the structure is simple and efficient, the use is convenient, the maintenance cost is low, the failure rate is low, the phenomenon that the front end of a feeding arm holding mechanism easily sticks steel and the use failure rate is high when a traditional slag stopping and feeding vehicle is used is avoided, and the technical effects of steel tapping and slag stopping efficiency and slag stopping success rate of a converter are improved.

Description

technical field [0001] The invention relates to the technical field of converter tapping slag blocking technology, in particular to a slag blocking bar feeding device. Background technique [0002] The working principle of the slag blocking rod: the slag blocking rod is a refractory product similar to a gyro with a guide rod with a small diameter. During the tapping process, use the feeding device to insert the slag blocking rod into the tapping hole. Because its density is between the molten steel and the slag, the slag blocking rod can float between the steel and slag interface, and block the tapping when the molten steel is discharged. mouth, so as to achieve the purpose of blocking slag and tapping. [0003] At present, the slag-stopping stick throwing vehicle is generally used to drop the slag-stopping stick. Its core component is the throwing arm with a clamping mechanism. The throwing arm of the slag rod extends into the furnace, and after reaching the predetermined...
