Problems solved by technology

Such a structure and working process lead to poor stability of the slag flow passing through the front of the granulator, and it cannot fall evenly. In this way, the granulation effect of the steel slag cannot be guaranteed, and it is also very easy to cause the liquid steel slag to fall directly into the pool and cause blasting. , affecting safety

Abstract

The invention provides an air chopped slag treatment device for steelmaking slag treatment applied to the energy-saving and environment-friendly steel slag technical field. A middle slag ladle (2) ofthe air chopped slag treatment device for steelmaking slag treatment is located below a large slag ladle (1), the lower portion of the middle slag ladle (2) communicates with a deslagging launder (3),a granulator (4) is located below the deslagging launder (3), a middle slag tank passing pipeline (5) is located in the middle slag ladle (2), the inner wall of the middle slag tank passing pipeline(5) is provided with slag launders (6) which are vertically arranged, and each slag launder (6) extends to the lower portion of the middle slag tank passing pipeline (5) from the upper portion of themiddle slag tank passing pipeline (5). The air chopped slag treatment device for steelmaking slag treatment can effectively guide the flowing state and the flowing speed of the steel slag in the middle slag tank, it is ensured that the slag flow is uniform and stable before passing through the granulator, the stability of the slag flow in front of the granulator can be improved, the slag flow evenly passes through the position in front of the granulator, and the steel slag granulation effect is ensured.

Description

technical field [0001] The invention belongs to the technical field of energy-saving and environment-friendly steel slag, and more specifically relates to a device for treating wind-broken slag of steelmaking slag. Background technique [0002] Converter slag air crushing technology In the slag treatment technology, the air crushing method for processing liquid steel slag has the characteristics of low cost, little impact on the environment, and good comprehensive benefits. It is a green and environmentally friendly slag processing method. Wind crushing slag treatment is to use the crane to lift the large slag tank containing the slag liquid to the top of the middle slag tank, open the granulator to compress the air, and then direct the crane to pour the slag liquid into the middle slag tank at a uniform speed, and the slag liquid is buffered by the middle slag tank Finally, the slag flow flows out from the slag discharge chute at a uniform speed, falls from the front of the...
