Recovering and forming method for waste steel slag of steel smelting furnace

Abstract

The invention relates to a recovering and forming method for waste steel slag of a steel smelting furnace. Equipment for the method comprises a bottom plate, a fixed frame and a forming device, wherein the fixed frame is mounted at the upper end of the bottom plate, a cross section of the fixed frame is of a U-shaped structure, and the forming device is arranged in the fixed frame and mounted on the bottom plate. The recovering and forming method for the waste steel slag of the steel smelting furnace can solve the problems that when existing equipment carries out brick making processing on thewaste steel slag, generally, mixed aggregates fill a forming cavity manually, manual filling efficiency is low, labor intensity is high, besides, the filling aggregates cannot be accurately regulatedand controlled, forming processing of green bricks is affected, meanwhile, when the existing equipment carries out brick making processing on the waste steel slag, the green bricks formed by pressingcannot be effectively pushed out, as a result, the collecting effect of the green bricks is poor, the green bricks are prone to deformation, subsequent preparation effects of the green bricks are affected and the like.

Description

technical field [0001] The invention relates to the field of steelmaking processing, in particular to a method for recycling and forming waste steel slag from a steelmaking furnace. Background technique [0002] Steel slag is waste slag produced in the metallurgical industry. The amount of steel slag produced in China has increased rapidly with the rapid development of the iron and steel industry. The steel slag produced by domestic iron and steel enterprises cannot be disposed of in time, resulting in a large amount of steel slag occupying land and polluting the environment. However, steel slag is not an unusable solid waste, which contains a large amount of available components such as slag steel, calcium oxide, iron, and magnesium oxide. Therefore, in order to create economic and environmental benefits for iron and steel enterprises, it is very necessary and urgent to choose appropriate treatment processes and utilization methods to develop the reuse value of steel slag. ...

AI Technical Summary

Problems solved by technology

[0005] The invention can solve the problem that when the existing equipment is processing waste steel slag for brick making, the mixed aggregate is usually manually filled inside the forming cavity, the artificial filling efficiency is low, the labor intensity is high, and the filled aggregate cannot be processed Accurate control affects the forming and processing of adobes. At the same time, when the existing equipment is used to make bricks from waste steel slag, it cannot effectively push out the adobes after pressing and forming, resulting in poor collection of adobes and a phenomenon that the adobes are prone to deformation , affect the follow-up preparation effect of adobe and other problems
