RECYCLING OF METALLURGICAL WASTES
Аннотация
This article presents the results of a research on the recycling of wastes from metallurgical plants in the city of Pavlodar at a steel smelting plant KSP Steel. The pellets were produced with aspiration dust and mixed with steelmaking (white) slag, ferrous sand, scale. The produced pellets were fired at a temperature of 600 ° C. The experience with the use of 20% white slag, 20% ferrous sand mixed with aspiration dust and 10% mill scale shows, after burning in a furnace, quite satisfactory strength, which is 80 kg / pellet. The principal possibility of steelmaking using pellets is shown. A positive effect on the recovery process of steelmaking has a carbonaceous reducing agent, which is in the composition of the charge. The pellets are fully capable of partially replacing iron and steel scrap, reducing the cost of metal.
