The invention relates to the technical field of iron and steel smelting, and discloses a metal waste slag cooling device for iron and steel smelting, which includes a base, and a rotating bracket is fixedly installed on the left and right sides of the upper end of the base, and the upper end base of the rotating bracket The left part of the rotating bracket is fixedly connected with a fan-shaped plate, the left part of the right end base of the rotating bracket is fixedly connected with a rectangular bar, the rear end of the rectangular bar is slidingly connected with a first slider, and the left side of the rear end base of the rotating bracket A cooling cylinder is rotatably connected to the upper part of the cooling cylinder, and a fixed frame is fixedly installed at the lower part of the front end of the cooling cylinder, and a second sliding block is slidably connected to the inner cavity of the fixed frame. The metal waste slag cooling device used in iron and steel smelting drives the connecting rod through the driving rod to make the cooling cylinder deflect back and forth, and cooperates with the ejector rod to be relatively intermittently squeezed by the fan-shaped plate, so that the sub-tube reciprocates in the main tube, thus increasing the cooling capacity. The cooling effect of the waste residue and the full use of water resources make the cooling effect 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...
