Abstract

The invention belongs to the technical field of steel refining equipment, and specifically discloses an environment-friendly steel refining furnace. The environment-friendly steel refining furnace comprises a furnace body, a bottom plate, a waste gas treatment box, a swing module, a stand column, an impurity-removal module and a telescopic gas exhaust bag, wherein the top of the furnace body communicates with the bottom of the waste gas treatment box through a gas guide tube; a connecting position of the waste gas treatment box and the gas guide tube is equipped with a solenoid valve; a pulling rope is mounted on the inner wall of the waste gas treatment box through a guide wire wheel; the stand column is fixedly connected to the centre position of the bottom of the waste gas treatment box; the swing module is arranged at the top end inside the waste gas treatment box; the telescopic gas exhaust bag is arranged inside the waste gas treatment box, so that one end of the telescopic gas exhaust bag communicates with the solenoid valve; the other end of the telescopic gas exhaust bag is fixedly connected to a connecting plate; an extrusion spring is fixedly connected between the connecting plate and the outer column surface of the stand column; and the top end of the connecting plate is fixedly connected to the other end of the pulling rope. The environment-friendly steel refiningfurnace can perform impurity removal on waste gas, and accelerates flow of treatment liquid, so that waste gas and the treatment liquid are sufficiently mixed, and therefore, waste gas treatment efficiency is effectively improved.

Description

technical field [0001] The invention belongs to the technical field of steelmaking equipment, in particular to an environment-friendly steelmaking furnace. Background technique [0002] Steelmaking refers to controlling the carbon content (generally less than 2%), eliminating harmful elements such as P, S, O, and N, retaining or increasing beneficial elements such as Si, Mn, Ni, and Cr, and adjusting the ratio between elements to obtain the best performance. The pig iron used for steelmaking is put into the steelmaking furnace and smelted according to a certain process to obtain steel. The emission of waste gas from iron and steel enterprises is very large, and the pollution area is wide; the temperature of the waste gas discharged from metallurgical kilns is high, and most of the waste gas discharged during the iron and steel smelting process is iron oxide dust, which has a small particle size and strong adsorption force, which increases the difficulty of waste gas managem...
