Oxy-fuel process for melting aluminum
Abstract
Abstract CASE, THE OXY-FUEL BURNERS ARE DISPOSED TO CREATE TURBULENCE WHICH SUBSTANTIALLY ENHANCES THE HEAT TRANSFER IN THE FURNACE, THEREBY VASTLY INCREASING THE MELTING RATE. PROCESS FOR MELTING METALS IN A FUEL-FIRED FURNACE, MORE SPECIFICALLY, FOR THE REMELTING OF SECONDARY ALUMINUM. THE PROCESS, WHICH MAY BE APPLIED IN A FURNACE OF THE REVERBERATORY TYPE, EMPLOYS ONE OR MORE OXY-FUEL BURNERS TO SUPPLEMENT THE HEATING OPERATION OF CONVENTONA AIRFUEL BURNERS. THE OXY-FUEL BURNER FLAME IS CAREFULLY CONTROLLED AS TO LENGTH, DIRECTON, VELOCITY, TEMPERATURE, AND FLAME CHEMISTRY SO THAT AT LEAST 90 PERCENT OF THE COMBUSTION IS COMPLETED BEFORE THE COMBUSTION PRODUCTS COME IN CONTACT WITH THE CHARGE OR THE BATH. SEVERAL ALTERNATIVE FURNACE BURNER ARRANGEMENTS ARE DISCLOSED WHICH RESPECTIVELY EMPLOY OXY-OIL BURNERS OF THE SELF-ATOMIZING TIPMIX TYPE, AND OXY-GAS BURNERS OF THE ROCKET TYPE. IN EACH
