What is the purpose of limestone in a blast furnace? - Quora
limestone is used to remove impurities in the furnace and the main impurity of the blast furnace is silica (sand and rock) which is silicon dioxide. silicon dioxide is a solid at furnace temperatures so it reacts with calcium oxide from the decomposition of limestone (CaCO3). this result into the formation of calcium silicate (CaSiO3) or slag which is a liquid. slag flows to the the bottom of the furnace where it floats on top of molten iron and is easly removed
