  • Method for estimating geographical distribution of cohesive zone in blast furnace
    Patent number: 4378994
    Abstract: A method for estimating the geographical distribution of a cohesive zone in a blast furnace which is intermittently charged with an iron ore material to produce molten iron substantially in a continuous manner is disclosed. The method comprises altering the whole or part of the composition of the charging iron ore material at a certain time point, measuring variations in the composition of produced molten iron ore slag over a given time period, and estimating the shape of the cohesive zone in the furnace on the basis of a pattern of variation of one selected component and the speed of gravitational descent of the charged material through the furnace.
