Abstract

A roller treatment process and a treatment device suitable for a total-amount steel slag treatment. The treatment process is: firstly, a slag tank (2) with the molten slag is tightly held by a slag tank tilting mechanism and moved to a slag inlet position, the slag tank (2) is tilted to pour the molten slag with good fluidity into a rotary roller device (5) through a feeding chute (51), so that a roller treatment is achieved; secondly, when the steel slag (3) without fluidity in the slag tank (2) cannot flow out, a slag removal machine (4) is used for pushing the high-viscosity slag or the solid slag into the roller device (5); and thirdly, the slag tank (2) is reversed by a large angle tilting to make the slag at the bottom of the tank drop into the roller device (5), so that the total-amount steel slag treatment of the same roller device (5) is achieved. The treatment device comprises a feeding system, the roller device (5), a particle slag conveying and storage system (7), a tail gas emission and purification system (6), a cooling water circulation system (8), a cold steel cleaning mechanism (10) and an electric control system (9); and the feeding system comprises the slag tank tilting mechanism (1), the slag tank (2), the molten slag (3) and the slag removal machine (4).
