The Uses of Manganese ore for burls removal from blast furnace In a blast furnace, manganese ore is used for washing the furnace lining. One of its main functions is to adjust the chemical composition ofthe slag.

Manganese combines with other impurities such as sulfur and oxygen. When added to the furnace during the operation, it helpsin the formation of manganese - rich slag. Thisslag can effectively absorb sulfur, which is a harmful impurity in steel - making. By reducing the sulfur content in the steel, the quality of the final steel product is significantly improved. Manganese- containing slag also helps in protecting the furnace lining. It forms a protective layer that reduces the erosion of the refractory materials of the furnace wall by the hot metal and slag, thus prolonging the service life of the furnace.
