Processing method and device of high-temperature solid steel slag

Abstract

The invention discloses processing method and device of high-temperature solid steel slag. In the processing method, the front of the traditional working cylinder is provided with a feed cylinder capable of containing a sufficient quantity of the high-temperature solid steel slag; the side surface or the end surface of the feed cylinder is provided with an automatic opening and closing door; the feed cylinder and the working cylinder are on a same axial line and rigidly fixedly combined together to form a large cavity, and the axial line forms a certain tilt angle outwards with a horizontal plane; the high-temperature solid steel slag is poured into the feed cylinder for one time during feed; a sealing door is automatically closed and locked after the feed is completed, the feed cylinder rotates according to set direction and speed under the action of a transmission device, and the high-temperature solid steel slag inside the feed cylinder gradually moves downwards with the rotation of the feed cylinder and feeds spirally to sequentially enter the working cylinder; the high-temperature solid steel slag inside the feed cylinder is continuously cooled and smashed with the rotation of the working cylinder, and finished product slag reaching certain granularity is delivered out of the working cylinder through an output device. The invention can realize the cleaning and efficient processing of the high-temperature solid steel slag.

Description

technical field [0001] The invention relates to a processing method and a processing device for high-temperature solid steel slag. Background technique [0002] Steel slag is an inevitable by-product of the steelmaking process, accounting for about 10-15% of steel production. Therefore, the rapid and effective treatment of steel slag, especially high-temperature steel slag, directly affects the normal operation of the steelmaking process and the sustainable development of steel enterprises. Due to the differences in the steelmaking process of each steel plant, the composition and temperature of steel slag produced during the smelting process are not the same: some high-temperature steel slags have good fluidity and can be poured like water; It can be easily poured out from the slag tank (the container for holding and transporting high-temperature steel slag, also known as the slag bag), and it can only be poured out of the slag tank by means of mechanical external force or t...

AI Technical Summary

Problems solved by technology

The disadvantage is that the processing objects of this process are strictly limited, and it can only process steel slag with good fluidity, but it cannot process steel slag with high viscosity and poor fluidity.

The disadvantage is that the existing drum device cannot realize the cleaning treatment of tank bottom slag

Due to the large size of the tank bottom slag and its lack of fluidity, it cannot be poured directly into the existing drum device. It is also necessary to equip a special slag dumping field to dump the tank bottom slag and part of the high-viscosity slag remaining in the slag dumping Traditional cooling and crushing are performed in the field, so the efficiency is affected, and there is dust.
