A method for realizing high-efficiency thermal stuffiness of liquid steel slag

Abstract

The invention discloses a method for achieving efficient hot disintegration of liquid steel slag. According to the method, an intelligent robot which is provided with an infrared temperature measuring gun is used for cooling high-temperature steel slag by water, and the temperature of the high-temperature steel slag ranges from 900 DEG C to 1100 DEG C; and after the red hot high-temperature steel slag is poured into a slag basin, the robot continuously conducts water spraying operation on the steel slag according to the infrared temperature measuring result until the temperature of the steel slag meets the requirement of hot disintegration. The method can achieve the operation of cooling the high-temperature steel slag by water and improve the operation efficiency of slag hot disintegration.

Description

technical field [0001] The invention relates to a process technology for continuous spraying of liquid steel slag in a converter to achieve high-efficiency hot stuffiness, in particular to a method for realizing high-efficiency hot stuffiness of liquid steel slag. Background technique [0002] The process of hot stuffy slag is as follows: After the converter slag is discharged, the slag tank is filled with converter liquid steel slag, and the canned converter liquid steel slag (or solid steel slag with a temperature greater than 300°C) is hoisted by a crane to the stuffy slag pit to dump the slag ( Sometimes it is also used to transport high-temperature steel slag by car and dump it directly into the slag pit). Every time high-temperature steel slag is poured, water is manually drawn to cool down to below 800°C, and then the next tank of steel slag is poured. When the slag in the slag pit meets the requirements (the upper free space is more than 500mm), cover the slag pit c...

[0012] According to the above literature retrieval and the inventor's on-the-spot investigation, it can be seen that in the steel mills that adopt the hot stuffy slag process in the whole country, in the process of using the hot stuffy process to process the converter steel slag, the control of the amount of water pumped manually is based on experience, and the amount of water is controlled by visual inspection. The water fetching operation is carried out by hot stuffy workers holding the high-pressure hose water pumping device, standing by the hot stuffy pool, and fetching water from the red slag in the pool. There are many safety hazards such as high temperature roasting and steam burns during operation.
