The invention discloses a method for preparing steel
smelting furnace materials from a
phosphorus-containing globulitic
hematite. The method comprises the following steps: adding adhesives with certain proportion into a globulitic
hematite which is broken and grinded to the
granularity smaller than 0.074mm and has the
mass percentage of 50% to 60%, mixing evenly, then, agglomerating, reducing and
sintering dried blocks with
coal as
reducing agent with the
sintering temperature of 1000 to 1050DEGC and with the time of 2 to 1.5h, breaking and
grinding cooled reduced blocks to smaller than 0.074mm with the
mass percentage of 80% to 90%, magnetically selecting and separating the blocks with the
magnetic field intensity of 0.1 to 0.12T, and obtaining the
metal iron powder, wherein the
adhesive is mixed by
sodium sulfate powder, solubor, natrium humate and
sodium xanthonate, the
mass percentage of
sodium sulfate powder in the
hematite is 5% to 8%, the mass percentage of solubor in the globulitic hematite is 1% to 2%, the mass percentage of natrium humate in the globulitic hematite is 0.5 % to 1%, and the mass percentage of sodium xanthonate in the globulitic hematite is 0.5 % to 1%. The method has high utilization efficiency, excellent dephosphorization effect, excellent product quality, high iron
recovery rate, low cost and low environment
pollution.
