Problems solved by technology

Steel slag is hard, large, and not easy to break. If these waste slags are piled up, it will cause environmental pollution. Moreover, a large amount of land acquisition and investment will be required to build or expand the slag yard, which will bring a great burden to society and enterprises.

Embodiment Construction

[0010] The invention comprises the following steps: 1. The steel slag is turned over from the slag tank to the slag pool, and after being heated by water pumping, the steel slag is pulverized in the steam. After 24 hours of water pumping, the steel slag becomes particles and powders with very small particle size. The car is loaded on the car and pulled to the slag raw material factory, and the large pieces of iron in it are directly returned to steelmaking; 2. The steel slag is poured into the raw material warehouse by a forklift, and the sieve above the raw material warehouse sends the large pieces of slag iron to steelmaking. The lower material enters the raw material warehouse; 3. The raw material warehouse enters the jaw crusher through the belt and two magnetic separations, and the large pieces of steel slag are crushed. After four magnetic separation and screening buildings, the fine material enters the ball mill, and the coarse material enters the Cone crusher grinding, ...

Abstract

The invention relates to a steel slag treatment method, which comprises the following steps: 1, the steel slag is poured from a slag ladle into a slag stewing pool, pulverized in steam by water-drilling stewing, loaded onto an automobile by a forklift and transported to a slag raw material factory, and the large iron in the steel slag is directly returned for steel making; 2, the steel slag is poured from the forklift to a raw material cabin; a sieve above the raw material cabin conveys the large iron for steel making; and the sieved steel slag enters the raw material cabin; 3, the raw material cabin is subjected to twice magnetic separation and enters a jaw crusher through a belt; the large steel slag is crushed and then subjected to four times of magnetic separation and screening; the fine steel slag enters a ball mill, and the coarse steel slag enters a cone crusher for milling; subsequently, twice magnetic separation is performed and then all steel slag enters the ball mill; aftercrushed by the ball mill, the steel slag is treated by two magnetic separators, and the separated refined powder flows into a refined powder pool through a water channel; the remaining tailing slurryflows into a tailing slurry pool through another water channel; and the remaining tailings are all discharged to the slag hill for paving. The invention can quickly treat the steel slag, make waste profitable, recycle the steel material to the great extent and realize zero emission.

Description

technical field [0001] The invention relates to a method for treating steel slag, which can recover steel materials to the greatest extent and realize zero discharge. Background technique [0002] In steelmaking production, about 0.1t of steel slag is discharged for every 1t of steel produced. Steel slag is hard, large, and not easy to break. If these waste slags are piled up, it will cause environmental pollution. Moreover, a large amount of land acquisition and investment will be required to build or expand the slag yard, which will bring great burdens to society and enterprises. Invention content: [0003] In order to overcome the shortcomings of the prior art, the present invention provides a steel slag processing method, which can quickly process steel slag, turn waste into treasure, recycle steel materials to the maximum extent, and realize zero discharge. [0004] The invention comprises the following steps: 1. The steel slag is turned over from the slag tank to th...
