Efficient Treatment Method and Apparatus for Multiphase Steel Slag

A high efficiency processing method for multiphase steel slag, where the steel slag is multiphase high temperature steel slag, comprising steel slag with high fluidity and highly viscous slag with poor fluidity or solid steel slag, wherein the method comprises the following steps:

• a slag tank with multiphase high temperature steel slag is held tightly by a tilting mechanism and moved to a slag feeding position, the slag tank is tilted so that the high temperature steel slag with high fluidity in the slag tank is poured through a feeding chute controllably at a set tilting speed, and into a storage bin that is placed at an inclined angle between a front part of a rotary drum and the feeding chute and rotates continuously with the rotary drum, the high temperature steel slag is separated from an inner wall of the storage bin with the rotation of the storage bin due to gravity, and slides controllably along a direction of inclination of the storage bin and moves into the rotary drum which is rotating, and is processed by a rotary drum processing;
• when the highly viscous slag or the solid slag remained in the slag tank cannot flow out because of its low fluidity, the slag tank is tilted continuously so that all the steel slag in the tank are poured into the feeding chute provided at the inclined angle, the highly viscous slag or solid slag slides into the feeding chute and the storage bin which is rotating through a funnel of the feeding chute due to gravity, and then slides slowly into the rotary drum with the rotation of the rotary drum and the storage bin due to gravity and the angle of inclination of the storage bin, and is processed by a rotary drum processing, where a speed of the highly viscous slag or solid slag sliding into the rotary drum is determined by the rotary drum.
