Analysis of the behavior of alkalis in a blast furnace

  • Published:
Metallurgist Aims and scope

The average monthly alkali balances for a 3200-m3 blast furnace are used to evaluate the effect of the furnace’s intake of alkalis on its performance indices. A method is proposed for evaluating the amount of alkalis removed from a furnace with the sludge and water from the gas-cleaning system. The effect of the main parameters of the smelting operation on the rate of removal of alkalis from the furnace is examined, and it is shown that all of the alkalis which enter the furnace can be removed if it is operated with a well-developed central gas flow and low-basicity slags.
