Abstract:Through the analysis and balance calculation on content of kalium, sodium and zinc of blast furnace raw fuel, it was summarized that the sinter and pellets are the main source; the slag is the important way for alkalis removal and the bag dust and the gravity dust is the main way for zinc removal. The measures to reduce alkalis and zinc enrichment were introduced, such as less using of high alkali and zinc content of raw materials, removing alkali and zinc in waste material, reducing the basicity of slag, reducing the block adsorption,etc. to reduce the harm of alkalis and zinc to the blast furnace.
