Abstract

The invention provides a slag adding method of a slab crystallizer slag adding robot. The slag adding method comprises the following steps: a slag adding robot with a slag adding spoon is mounted on a casting platform of a slab crystallizer; the slag adding robot determines a moving path of the slag adding spoon according to the size data of a section of the slab crystallizer and a water port; the slag adding robot controls a machine arm to drive the slag adding spoon thereon to perform a reciprocating motion according to the moving path; and protection slag is added on the surface of molten steel in the slab crystallizer. The slag adding method has such beneficial effects as smooth and uniform slag adding, keeping of initial shape of the protection slag and environmental protection, and solves such problems as slag blockage, nonuniform slag adding, crushing of the protection slag and easy generation of the dust pollution in traditional automatic slag adding.

Description

Technical field

[0001] The invention relates to the field of steelmaking and continuous casting, in particular to a slag adding method of a slag adding robot for a slab crystallizer. Background technique

[0002] The mold flux on the surface of the molten steel in the continuous caster mold can absorb the inclusions in the molten steel, prevent the molten steel from being oxidized with the air and act as a lubrication, which is of great significance for improving the quality of the billet. The traditional method of adding mold slag (referred to as adding slag) to the crystallizer is manual adding method. Compared with the traditional manual adding method, automatic slag adding to the mold has the advantages of uniform slag addition, saving mold slag and reducing labor intensity of workers. The existing automatic slag adding methods mainly include the following methods: First, the mold slag is transported from the high slag hopper to the low crystallizer by its own weight. The dis...
