Abstract:

Results are given for analysis of agglomerate and pellet physicochemical properties. It is shown that with transfer of blast furnace smelting into an operating regime with a high proportion unfluxed pellets in a charge requires changing the main slag regime parameters, and also the furnace charging regime. It is established that due to the difference in agglomerate and pellet physicomechanical properties, and also as a result the high corrosiveness of primary slag obtained using unfluxed pellets, it is necessary to change the regime for material charging into a furnace. With an increase in the proportion of Sokolovo-Sarbaiskii Ore Mining and Processing Combine pellets in Magnitogorsk Metallurgical Combine blast furnace charge, there is a reduction in amount of magnesium in final blast furnace slags. This is accompanied by an increase in molten slag viscosity, a reduction in its sulfur absorbing capacity, and also an increase in the temperature range for iron ore mix melting with an increase in bottom gas pressure drop and limiting melt blast force.
