METHOD FOR IRON-MAKING WITH FULL OXYGEN AND HYDROGEN-RICH GAS AND EQUIPMENT THEREOF

摘要

THE PRESENT INVENTION PROVIDES A METHOD OF IRONMAKING USING FULL-OXYGEN HYDROGEN-RICH GAS WHICH COMPRISES HOT TRANSFERRING AND HOT CHARGING THE HIGH-TEMPERATURE COKE, SINTER AND PELLET INTO THE IRON MAKING FURNACE (3) THROUGH TRANSFERRING AND CHARGING DEVICE, AND INJECTING OXYGEN AND HYDROGEN-RICH COMBUSTIBLE GAS AT A PREDETERMINED TEMPERATURE INTO THE IRON MAKING FURNACE (3) THROUGH THE OXYGEN TUYERE AND THE GAS TUYERE DISPOSED AT THE IRON MAKING FURNACE (3), RESPECTIVELY. IT ALSO PROVIDES AN APPARATUS FOR IRON MAKING USING FULL-OXYGEN HYDROGEN-RICH GAS WHICH COMPRISES A RAW MATERIAL SYSTEM, A FURNACE ROOF GAS SYSTEM, A COKE OVEN GAS INJECTING SYSTEM, A DUST INJECTING SYSTEM, A SLAG DRY-GRANULATION AND RESIDUAL HEAT RECOVERING SYSTEM AND AN OXYGEN SYSTEM (11). ADDITIONALLY, IT FURTHER PROVIDES AN APPARATUS AND METHOD FOR HOT TRANSFERRING AND HOT CHARGING OF IRON MAKING RAW MATERIAL. FIG. 1
