Blast furnace is a continuous unit of shaft-type. The charging of burden is conducted from above‚ through the typical charging unit‚ which is the gas damper of the blast furnace. It is reduced rich iron ore (at present time resources of rich iron ore are preserved only in Australia and Brazil)‚ sinter or pellets in the blast furnace. Sometimes granular pellets are used instead of crude ore. Blast furnace consists of five constructive elements: top cylindrical part is top throat‚ that is necessary

Silicon Control in Blast Furnace Hot Metal is one of the most critical problems in today’s Iron Making. With deterioration in quality of iron ore day by day‚ silica load in the burden material has a steady increase. The same story is with the Coke ash‚ which passes good amount of silicon in the hot metal. Every 0.1% reduction in silicon in the hot metal gives rise to 1.5 % increase in hot metal production. In the competitive scenario of today’s Iron Making hence it is necessary to reduce every bit
