Title:
IMAGE RECOGNITION-BASED AUTOMATIC DESLAGGING METHOD AND SYSTEM USING CONVERTER SLAG REMAINING PROCESS
Document Type and Number:
WIPO Patent Application WO/2021/197168
Kind Code:
A1
Abstract:
Disclosed in the present invention is an image recognition-based automatic deslagging method using a converter slag remaining process, comprising the steps of: determining a target deslagging amount on the basis of the weight of slag generated during converter smelting and a target amount of remained slag during smelting using a slag remaining process; acquiring and storing a real-time image of a hot-state slag stream during converter deslagging; determining characteristic boundaries of the hot-state slag stream; selecting a tracking area; according to image recognition, calculating, in real time, the volume Vi of slag in the tracking area and the total weight Gt of the slag poured out at a deslagging time t; when the volume Vi of the slag in the tracking area is greater than a set measurement threshold Vmin, controlling, on the basis of a weight change rate dGt/dt, a converter to tilt in real time at an angular velocity ωi, and obtaining a real-time tilting angle of the converter; calculating a real-time position of a slag ladle trolley, so that a slag ladle receives the slag poured out from the converter in real time; and when a difference value between a total deslagging weight Gt and a target deslagging amount G0 is a preset deviation value, stopping the tilting of the converter and starting the shaking-back of the converter. Also disclosed in the present invention is an image recognition-based automatic deslagging system using a converter slag remaining process.
