ArticleName Estimation of extension and shape of cavities in tuyere areas of a blast furnace
ArticleAuthor G. Yu. Kryachko, R. V. Avdeev, Yu. V. Belyaev, Yu. K. Lebed’
Abstract Analysis presented in the paper shows on inexpedience of one-relationship generalization of experimental data about extension of sub-tuyere areas, formed during smelting of different kinds of iron at different operating conditions. Analysis of relation between variables reflecting direct and indirect measurements of extension of loosed area has confirmed substantiation of estimation of dimensions of the area for varying CO2 concentration in the hearth gas.
keywords Blast furnace, iron, hearth, tuyere, blowing, hearth gas, oxygen.
