Abstract:

The effect of alkaline compounds on blast furnace operation is studied. It is shown that the main mass of alkaline compounds enters a blast furnace with sinter, coke ash, and pellets, and the main part of alkali emerges from a blast furnace with slag. A quantitative effect is established for an increase in the emergence of alkali with slag with a reduction in final slag basicity. The periodic nature of alkali removal with slag is established. It is found that it is necessary no less frequently that once every 4-5 days in each blast furnace to carry out two to three operating shifts with final slag reduced basicity (CaO/SiO2) (lower by 0.05-0.15 units than prescribed by the production chart). The technology proposed for alkaline compound removal is protected by an RF patent and implemented at the Magnitogorsk Metallurgical Combine since 2012.
