Abstract
PURPOSE: To manufacture the blast furnace raw material pellets of economizing energy and resource and of no enviromnental pollution, by adding portland cement and mixing MgO powder making allowance and then, granulating and curing after blending iron sand etc. for regulating grain size and moisture to the iron source, such as collected dust or sludge etc. of iron factory.
CONSTITUTION: Iron sand or fine ore for grain size and moisture regulation, is blended with the main raw material composed of collected dust, sludge or scale powder etc. of iron factory. Next, MgO clinker powder or serpentine powder for MgO component regulation, is mixed, granulated and cured. By the above method, non-calcined pellets having desired solftening or melting temperature, are obtained by changing mixing quantity of MgO component.
