Automatic converter lifting control method and system in converter tapping process

Abstract

The present invention discloses an automatic converter lifting control method and system in a converter tapping process. The method includes the following steps: mounting a camera on a proper position of a tapping side of a converter, and judging slag overflow conditions at a converter mouth and a tapping hole in a tapping process according to videos, shot by the camera, at the converter mouth and under the converter; processing a converter mouth slag overflow detection signal and an under-converter slag overflow detection signal to generate a converter lifting instruction; when the converter is in a waiting state, controlling the converter to be lifted up after receiving a converter lifting instruction, not lifting up the converter within a certain time after lifting up the converter once, and pressing down the converter after delaying for a period of time since the converter is lifted up. According to the automatic converter lifting control method provided by the present invention, the situation that slag overflows from the converter mouth in an automatic tapping process is remarkably reduced, the labor intensity of workers is reduced, and the automation degree and the intelligent level of converter tapping are improved.

Description

Technical field [0001] The present invention relates to the field of converter automatic control technology, and more particularly to a process of automatic lifting furnace control during the converter. Background technique [0002] The converter steelmaking is the most important steelmaking method in the world, and steel production accounts for more than 65% of the total number of world steel production. With the increase in the demand for high-quality steel, such as car board, high-end ship board, electrician steel, stainless steel, etc., the steel clean and cleanness requirements for converter steelmaking are also increasing, so the impurity element content of steel water should be as small as possible. In the end of the converter steelmaking, the steel water is poured into the steel bag from the converter, and the slag will also flow into the steel bag along with the steel water, affect the cleanliness of the steel water. Therefore, strictly controlling the steel process is a...
