INSTALLATION AND METHOD OF STABILISATION AND INERTISATION OF SLAG, OBTAINED WHEN PRODUCING STEEL AT STEEL WORKS AND IN BLAST FURNACES Russian patent published in 2017 - IPC C04B5/00 C04B18/14 

Abstract RU 2633456 C2

FIELD: metallurgy.

SUBSTANCE: method for stabilising and inerting the slag includes the phases of introducing the components into the mixing device and the steps in which the slag is ground in a grinding device to produce particulate slag as particulate matter. The mixing means of the mixing device are activated. Pour the first amount of water into the mixing device. Waiting for the first period of time T1, beginning with the completion of the first water filling. Load crushed slag into the mixing device. Waiting for a second period of time T2, starting with the completion of slag loading into the mixing device. A hydraulic binder is introduced into the mixing device. Waiting for the third period of time T3, beginning with the completion of the loading of the hydraulic binder. A fluidifying additive is added to the mixing device. Waiting for the fourth time period T4, beginning with the completion of the loading of the fluidifying additive. A second amount of water is poured into the mixing device. Waiting for the fifth period of time T5, starting with the completion of pouring the second amount of water. The mixed product is withdrawn from the mixing device and the mixed product is maintained for a sixth period of time T6 or ripening time in a storage vessel with possible continuous or intermittent vibration to obtain an inert and mature product based on the slag. An inert and mature product is withdrawn from the storage container. Grind in a crushing device in order to achieve certain sizes of inert and mature product. In this case, a total amount of water corresponding to the sum of the first and second amounts of water is introduced relative to the total amount of components charged to the mixing device. Introduce slag, hydraulic binder and the fluidifying additive.

EFFECT: obtained product quality improvement.
