Method of making steel shot

Claim 1

THE METHOD OF MAKING ROUND AND SOLID STEEL SHOT REASONABLY FREE FROM CRACKS AND HOLLOWS AND CONTAINING CARBON, MANGANESE, SILICON, AND IRON, WHICH COMPRISES MELTING THE ABOVE MATERIALS IN AN OPEN BATH FURNACE WHILE IT IS IN AN OXIDIZED STATE THROUGHOUT THE HEAT, BOILING THE MOLTEN BATH AT A TEMPERATURE OF APPROXIMATELY 2700-2750* F. TO REMOVE GASES AND INCLUSION OF METALLIC OXIDES, MAINTAINING THE SILICON CONTENT BELOW 0.10% UNTIL THE FINAL SILICON ALLOYING, CONTROLLING THE COMPOSITION OF THE SLAG, DEOXIDIZING THE BATH AND ALLOYING THE BATH TO 1.20 TO 1.40% CARBON, 1.00 TO 1.50% MANGANESE AND 0.40 TO 0.90% SILICON THEN ADDING AT LEAST ONE STRENGTHENING ALLOY METAL SELECTED FROM THE GROUP CONSISTING OF CHROMIUM NOT EXCEEDING 5.0% MOLYBDENUM NOT EXCEEDING 5.0% VANADIUM NOT EXCEEDING 0.4%, NICKEL NOT EXCEED ING 2.5%, AND COPPER NOT EXCEEDING 1.0% AND THE BALANCE SUBSTANTIALLY IRON, POURING THE METAL, DISINTEGRATING IT INTO PARTICLES OF LESS THAN 0.1 DIAMETER, INITIALLY QUENCHING THE DISINTEGRATED PARTICLES IN A MILD QUENCHING MEDIUM, DRYING THE DISINTEGRATED PARTICLES, AND THEN HEAT TREATING THE PARTICLES AT A TEMPERATURE CLOSE TO THE ACM LINE OF THE FEC DIAGRAM, TO PRODUCE A TEMPERED MARTENSITE MICRO-STRUCTURE.
