Problems solved by technology

[0003] Yet existing blast furnace ironmaking slag has the following problems when processing, one, blast furnace ironmaking slag passes through air cooling solidification after blast furnace slag discharge, needs the condensed slag to be pulverized, and existing blast furnace ironmaking slag treatment equipment crushing effect Poor; 2. When the existing blast furnace ironmaking slag processing equipment crushes the slag, it does not handle the smoke and dust and the high temperature in the process well, causing certain pollution to the environment

Abstract

The invention relates to a treatment method for blast furnace ironmaking slag, which uses a blast furnace ironmaking slag treatment equipment. The present invention can solve the following problems existing in the treatment of the existing blast furnace ironmaking slag: 1. After the blast furnace ironmaking slag is discharged from the blast furnace, it is cooled and solidified by air, and the condensed slag needs to be pulverized, while the existing blast furnace ironmaking slag The crushing effect of the processing equipment is poor. When the existing blast furnace ironmaking slag processing equipment crushes the slag, it fails to properly handle the dust and high temperature generated during the process, causing environmental pollution. The invention can effectively crush the slag, and improves the efficiency of crushing the slag. During the process of crushing the slag, the remaining temperature in the slag can be cooled in time, and the dust generated in the process of crushing the slag can be filtered and discharged. protect environment.

Description

technical field [0001] The invention relates to the technical field of slag treatment, in particular to a treatment method for blast furnace ironmaking slag. Background technique [0002] A method for continuously producing liquid pig iron in a vertical reactor—a blast furnace—using coke, iron-containing ores (natural rich lump ore, sinter and pellets) and flux (limestone, dolomite). It is an important link in modern steel production. Modern blast furnace ironmaking is transformed and developed from the ancient shaft furnace ironmaking method. Although many ironmaking methods have been researched and developed by countries all over the world, blast furnace ironmaking is still the main method of modern ironmaking because of its relatively simple process, large output, high labor productivity and low energy consumption. Its output accounts for the world's total pig iron production. More than 95% of the The waste slag produced when the blast furnace smelts pig iron is slag. ...
