Process for refining ferrous materials

Claim 1

IN A PROCESS FOR REFINING A HOT FERROUS MELT WITHIN A REACTION CHAMBER, IN WHICH A GAS STREAM RICH IN OXYGEN IS INJECTED INTO CHAMBER AT A LOCATION CLOSE TO THE IS INJECTED INTO SAID CHAMBER AT A LOCATION CLOSE TO THE SURFACE OF THE MELT TO BURN CARBON MONOXIDE DEVELOPED SURFACE OF THE MELT TO BURN CARBON MONOXIDE DEVELOPED WITHIN SAID CHAMBER, THE IMPROVEMENT WHICH COMPRISES THE STEPS OF DIVIDING SAID GAS STREAM INTO A FIRST PORTION THE STEPS OF DIVIDING SAID GAS STREAM INTO FIRST PORTION WHICH IS INJECTED INTO SAID CHAMBER ABOVE SAID SURFACE WHICH IS IBJECTED INTO SAID CHAMBER ABOVE SAID SURFACE AND A SECOND PORTION WHICH IS INJECTED INTO SAID CHAMBER BELOW SAID SURFACE, AND ADMIXING WITH SAID GAS STREAM A CONTINUOUS CHARGE OF A GRANULAR, HEAT-ABSORBENT SOLID CONTINOUS CHARGE OF A GRANULAR, HEAT-OBSORBENT SOLID MATERIAL OF SLAG-FORMING CHARACTER AT A RATE SUFFICIENT TO LOWER THE COMBUSTION TEMPERATURE OF THE CARBON MONOXIDE TO A MAXIMUM OF SUBSTANTIALLY 1800*C. IDE TO A MAXIMUM OF SUBSTANTIALLY 1800*.
