Steel smelting device

Abstract

The invention belongs to the field of iron and steel smelting, and relates to an iron and steel smelting device which comprises a shell, four supporting columns are fixedly arranged on the lower side of the shell, an upper cover is arranged on the upper side of the shell in a sliding mode, an exhaust hole is fixedly formed in the upper side of the upper cover, and a gas tank is fixedly arranged on the right side of the shell. A gas output pipe is fixedly arranged on the upper side of the gas box, an oxygen box is fixedly arranged on the left side of the shell, and an oxygen output pipe is fixedly arranged on the upper side of the oxygen box. In the steel smelting process, the smelting vessel can be rotated through the rotating device, so that raw materials in the smelting vessel can be uniformly heated, meanwhile, the materials in the smelting vessel can be stirred through the stirring device, it is guaranteed that the raw materials can be continuously overturned in the smelting process, it is guaranteed that the raw materials can be uniformly heated, and the production efficiency is improved. And meanwhile, harmful gas generated in the smelting process can be effectively treated.

Description

technical field [0001] The invention belongs to the field of iron and steel smelting, and in particular relates to an iron and steel smelting device. Background technique [0002] As we all know, iron and steel smelting is a general term for steel and iron metallurgical processes. Industrially produced iron is divided into pig iron (more than 2% carbon content) and steel (less than 2% carbon content) according to the carbon content. Most modern ironmaking uses blast furnace ironmaking, and some use direct reduction ironmaking method and electric furnace ironmaking method. Steelmaking mainly uses pig iron smelted in blast furnaces, sponge iron smelted by direct reduction ironmaking, and scrap steel as raw materials, which are smelted into steel by different methods. The basic production process is to smelt iron ore into pig iron in an iron-making furnace, then use pig iron as raw material to smelt steel by different methods, and then cast it into ingot or continuous casting...

AI Technical Summary

Problems solved by technology

[0003] 1. At present, smelting needs to use blast furnace with low combustion rate, and the heat loss of blast furnace is large;

[0004] 2. The discharge of harmful substances after smelting and combustion is relatively high, which will have an impact on operators and the environment;

[0005] 3. At the same time, the temperature inside the blast furnace is relatively concentrated, and the metal cannot be heated evenly, which affects the smelting effect and reduces the smelting efficiency
