Metal waste slag cooling device used for steel smelting

Abstract

The invention relates to the technical field of steel smelting, and discloses a metal waste slag cooling device used for steel smelting. The metal waste slag cooling device comprises a base, wherein the left side and the right side of the upper end of the base are fixedly equipped with rotary brackets; the left parts of the upper-end bases of the rotary brackets are fixedly connected to a fan-shaped plate; the left parts of the right-end bases of the rotary brackets are fixedly connected to a rectangular strip; the rear end of the rectangular strip is in sliding connection to a first slide block; the left parts of the rear-end bases of the rotary brackets are rotatably connected to a cooling barrel; the lower part of the front end of the cooling barrel is fixedly equipped with a fixed frame; and the inner cavity of the fixed frame is in sliding connection to a second slide block. According to the metal waste slag cooling device used for steel smelting disclosed by the invention, a drive rod drives a connecting rod, so that the cooling barrel deflects back and forth, and is matched with an ejector rod for being relatively extruded intermittently by the fan-shaped plate, and a secondary tube moves back and forth in a primary tube, and therefore, waste slag cooling effect is improved, water resources are sufficiently utilized, and cooling effect is better.

Description

technical field [0001] The invention relates to the technical field of iron and steel smelting, in particular to a metal waste slag cooling device for iron and steel smelting. Background technique [0002] Most of the traditional ironmaking uses blast furnace ironmaking. Blast furnace ironmaking is to reduce iron ore in the blast furnace and melt it into pig iron. It is easy to operate, low in energy consumption, and low in cost. Blast furnace slag and steel slag are produced in the blast furnace, which is a kind of solid waste produced in the smelting process. Since part of the molten steel will remain in the waste slag, this part of the waste slag can continue to be used after treatment. [0003] Because the temperature of the waste slag just out of the furnace is too high to be used directly, it needs to be cooled. The current cooling device directly uses cooling water to spray the waste slag, but the waste slag just out of the furnace is prone to clumping, so it is direc...
