Выявление закономерностей поступления агломерата различной крупности из бункера БЗУ лоткового типа

Abstract

Проведением физического моделирования на лабораторной установке БЗУ лоткового типа исследовали действие расхода и последовательности размещения в бункере крупной и мелкой фракции агломерата на коэффициент равномерности его поступления в колошниковое пространство.

By conducting the industrial tests on the blast furnaces of OJSC"MMK" volume 1370 m3 the role of the ratio of consumption of natural gas and blowing to tuyeres to the course of blast furnace melting was investigated. With increasing uniformity coefficient from 0.91 to 0.95, conditions were created to increase natural gas consumption by 500 m3/hr with replacement ratio them coke equal to 0.72 kg/m3. The effect of the consumption and sequence of the placement in the hopper of the large and fine fraction of sinter by a factor of uniformity of its revenues into the throat space was investigated by the physical modeling conduct in the laboratory bell-less charging device of a gutter type.
