Automatic slag adding system and method for H-shaped blank continuous casting crystallizer

Abstract

The invention discloses an automatic slag adding system and method for an H-shaped blank continuous casting crystallizer. The automatic slag adding system comprises a linear driving unit, connection devices, slag adding pipe fixing devices, a slag adding pipe component, a slag adding nozzle component and a controller which are arranged along the web direction of the H-shaped blank continuous casting crystallizer, wherein the slag adding nozzle component is connected to the outlet end of the slag adding pipe component. The automatic slag adding method for the H-shaped blank continuous casting crystallizer comprises the following steps: the automatic slag adding system for the H-shaped blank continuous casting crystallizer is provided; automatic slag adding is performed when a left side slag adding pipe and a right side slag adding pipe enter wing plates of the H-shaped blank continuous casting crystallizer along with slag adding nozzles which are separately connected with the corresponding slag adding pipes; slag adding is automatically stopped when the left side slag adding pipe, the right side slag adding pipe and the slag adding nozzles which are separately connected with the corresponding slag adding pipes leave the wing plates of the H-shaped blank continuous casting crystallizer; and a slag adding nozzle which is connected with a middle slag adding pipe moves along the web direction of the H-shaped blank continuous casting crystallizer for continuous automatic slag adding. An automatic slag adding technology which is uniform in slag adding is realized on the H-shaped blank continuous casting crystallizer, and the blank in the technical field is filled up.

Description

technical field [0001] The invention belongs to the field of automatic slag adding to continuous casting crystallizers, in particular to an automatic slag adding system and method for H billet continuous casting molds. Background technique [0002] The mold slag covering the surface of the molten steel in the continuous casting crystallizer is used to lubricate the molten steel, prevent secondary oxidation of the molten steel in contact with air, and absorb inclusions in the molten steel. Therefore, mold slag plays a very important role in improving the quality of continuous casting slabs. The traditional method of adding mold slag to the crystallizer is manual adding method. In recent years, some automatic slag adding devices have appeared. Compared with manual adding method, these devices can add slag evenly, improve the quality of continuous casting billet, and reduce labor labor. Strength and saving mold slag and other advantages. However, the existing continuous casti...

Problems solved by technology

However, the existing continuous casting crystallizer automatic slag adding system is only suitable for continuous casting molds such as square billets, round billets and slabs with regular shapes, but not for H-shaped billets with irregular shapes and complex structures. Therefore, it is urgent to develop an automatic slag adding technology for the H-shaped billet continuous casting mold. It is planned to achieve uniform slag addition on the H-shaped billet continuous casting mold, improve the quality of the H-shaped continuous casting billet, and reduce the labor intensity of workers. And saving mold slag, etc.
