Abstract

The invention relates to a blast furnace spreading device, in particular to an uniform spreading device for blast furnace smelting. The technical problem to be solved by the invention is to provide the uniform spreading device for blast furnace smelting. In order to solve the technical problem, the invention provides the uniform spreading device for blast furnace smelting; the uniform spreading device for blast furnace smelting comprises left and right cylinders, left and right extension rods, motors, rotating shafts, a left disc-shaped grinding disc, a hopper, a belt conveying device, a right disc-shaped grinding disc and a fan; the left and right extension rods are arranged at the right sides of the left and right cylinders; the left and right cylinders are connected with the left and right extension rods; the motors are arranged at the right sides of the left and right extension rods; the left and right extension rods are connected with the motors; and the rotating shafts are arranged at the right sides of the motors. The uniform spreading device for blast furnace smelting, provided by the invention, rubs and crushes such raw materials as iron ores through grinding teeth of the grinding disc, improves the crushing degree of such raw materials as iron ores, and realizes uniform spreading.

Description

technical field [0001] The invention relates to a material spreading device for a blast furnace, in particular to a uniform material spreading device for blast furnace smelting. Background technique [0002] Blast furnace ironmaking is the main method of modern ironmaking and an important link in iron and steel production. This method was developed and improved by ancient shaft furnace ironmaking. Although many new ironmaking methods have been researched and developed by various countries in the world, due to the good technical and economic indicators of blast furnace ironmaking, simple process, large production volume, high labor productivity and low energy consumption, the iron produced by this method still accounts for the total iron production in the world. More than 95% of. [0003] During blast furnace production, iron ore, coke, and flux for slagging are loaded from the top of the furnace, and preheated air is blown in from the tuyeres located at the lower part of t...
