Abstract

The invention provides an automatic slag powder adding device and an automatic slag powder adding method of a continuous casting machine crystallizer. The automatic slag powder adding device comprises a slag bucket, a feeding regulation pipeline, a slag adding mouth, a linear drive unit and a controller, wherein the input end of the feeding regulation pipeline is connected with the slag bucket; the slag adding mouth is connected with the output end of the feeding regulation pipeline; the slag adding mouth is arranged on the linear drive unit and performs reciprocating motion on the linear drive unit; the controller is connected with the feeding regulation pipeline and the linear drive unit and is used for controlling the feeding regulation pipeline to be connected or disconnected and usedfor controlling the linear drive unit. In the slag adding process, the automatic slag powder adding device provided by the invention directly transports slag powder to the slag feeding mouth from theslag bucket via a feeding hose, and finally sprays the slag powder onto molten steel surface; granular slag powder is not broken by stirring in the transportation process, keeps the original shape ofgranule and ensures the motility of the granular slag powder, and thus the granular slag powder is evenly distributed on the molten steel surface. Meanwhile, the invention has the effect of less dust, pollution and the like and has the characteristics of high efficiency and low cost.

Description

technical field [0001] The invention relates to a slag adding device, in particular to an automatic mold slag adding device for a mold of a continuous casting machine. Background technique [0002] The mold slag on the molten steel in the mold of the continuous casting machine can absorb the inclusions in the molten steel, prevent the molten steel from being oxidized in contact with air, and play a lubricating role, which is very important for improving the quality of the billet. The traditional method of adding mold slag to the crystallizer is manual adding method. Compared with the traditional manual adding mold slag, automatic mold slag addition has the advantages of evenly adding slag, saving mold slag, and reducing labor intensity of workers. [0003] The existing device for automatically adding mold slag to the crystallizer has a slag feeding pipe swinging type, which has the disadvantages of large volume and too long slag feeding pipe, and the slag feeding pipe swings...
