Metal smelting liquid recovery device based on steel smelting machining and use method thereof

Abstract

The invention discloses a metal smelting liquid recovery device based on steel smelting machining and a using method thereof, in particular to the field of steel smelting machining. The metal smelting liquid recovery device comprises a base, a supporting column, a vertical rod and a box body, a top plate is fixedly installed at the top end of the box body, a residue inlet hopper is fixedly installed at the top end of the top plate, and the bottom end of the box body communicates with a heating furnace. According to the device, a partition plate and a heat dissipation net are arranged, metal waste residues are partitioned in the residue inlet hopper through the partition plate, so that the metal waste residues rotate along with the residue inlet hopper under the condition that the metal waste residues are equally divided, the metal waste residues are not prone to adhering to one another, heat on the surfaces of the metal waste residues is dissipated through the heat dissipation net inside the residue inlet hopper, the metal waste residues meet the requirements of separation and cooling under the condition of constant-speed rotation, metal smelting liquid which is not recycled cannot adhere to the surfaces of the metal waste residues, the problem that the temperature of the waste residues just coming out of a boiler is too high, and the waste residues are prone to being adhered together under the temperature change of metal smelting liquid, namely molten steel, in the waste residues is avoided, and recovery of the metal smelting liquid is accelerated.

Description

technical field [0001] The invention relates to the technical field of steel smelting and processing, more specifically, the invention relates to a metal smelting liquid recovery device for steel smelting and processing and a method for using the same. Background technique [0002] Iron and steel smelting is the general term for steel and iron metallurgical processes. Industrially produced iron is divided into pig iron and steel according to the carbon content. Most modern ironmaking uses blast furnace ironmaking, and some use direct reduction ironmaking and electric furnace ironmaking. Among them, steel smelting mainly uses pig iron smelted in blast furnaces, sponge iron smelted by direct reduction ironmaking, and steel scrap as raw materials, and is smelted into steel by different methods. The basic production process is to convert iron ore Stone is smelted into pig iron, and pig iron is used as raw material to smelt into steel by different methods, and then cast into ingo...

Problems solved by technology

[0003] However, in the process of steel smelting in the prior art, a lot of metal waste slag will be generated, and direct disposal will not only cause environmental pollution, but also cannot recycle the metal smelting liquid in the metal waste slag, which cannot meet the requirements of environmental protection , and caused a waste of metallurgy; and because the temperature of the waste slag just coming out of the boiler is too high, the metallurgy in the waste slag, that is, the molten steel, is easy to make the waste slag stick together under the change of temperature, which affects the recovery of the metallurgy ; and in the process of recycling the metallurgy, it is necessary to separate the metal waste slag from the metallurgy in order to achieve the recycling of the metallurgy; in the process of recycling the metallurgy, the metallurgy is easy to solidify without heat treatment It is difficult to obtain liquid metallurgy
