Method and system for automatically pouring slag in converter slag remaining process

Abstract

The invention discloses a method for automatically pouring slag in a converter slag remaining process. The method comprises the following steps of determining a target slag pouring amount based on the weight of the slag generated in a converter smelting process and a target slag remaining amount in smelting by adopting a slag remaining process; collecting and storing a real-time image of slag flow in a converter deslagging process, and determining a characteristic boundary of the slag flow; selecting a tracking area; calculating a slag area Si in the tracking area in real time, and detecting the weight Gi of the slag in a slag ladle in real time; when the area Si of the slag in the tracking area is larger than a set detection threshold value Smin, based on the weight Gi of the slag in the slag ladle, controlling the real-time tilting angular speed omega i of a converter, obtaining the real-time tilting angle of the converter according to the real-time tilting angular speed, and calculating the real-time walking displacement of the slag ladle, so that the slag ladle receives the slag poured out of the converter in real time; and when the weight Gi of the slag in the slag ladle reaches the target slag pouring amount G0 or the weight Gi and the target slag pouring amount G0 have an allowable deviation value, stopping the converter from tilting, and starting the converter to swing back. In addition, the invention further discloses a system for automatically pouring the slag in the converter slag remaining process.

Description

Technical field [0001] The present invention relates to a method and system of residue, and more particularly to a method and system for automatic apodulating. Background technique [0002] Currently, all major steel mills have basically adopted model steel making and implementation of one-button operation that is blown, and with the converter automatic steel technology has also been put into use, the process of the converter is also The manual operation is transformed into automatic operation. In converter smelting, there is a "converter ridge process" is widely used in converter steelmaking technology. The process uses the iron oxide and calcium oxide and calcium oxide of the previous furnace, reducing steel consumption and excipient consumption, and is conducive to the formation of the next furnace before the formation of the slag. The process is characterized by resembling the slag, but all the slag is poured out, but a certain amount of slag is retained for a furnace smeltin...
