• Choosing the right technologies for reverb furnaces

    The first successful appliion of oxygen in aluminum melting was on a rotary furnace. This appliion used a combination of airfuel and oxyfuel through Air Products' EZFire™ airoxyfuel combustion technology, which was developed in the late 80's. The first commercial installation was in 1989 on a 25,000 pound single pass rotary furnace

  • High Efficiency Furnace with OxyFuel Combustion and Zero ...

    Oxyfuel combustion is the process of burning a fuel using pure oxygen instead of air as the primary oxidant. Since the nitrogen component of air is not heated, fuel consumption is reduced, and higher flame temperatures are possible. Therefore, it is applied to melting furnace such as glass melting tank and cast iron melting furnace.

  • The Manufacture of Steel

    produces a slag which blocks conventional blast furnaces as it has a high melting point. The iron produced in this way always contains high levels of impurities making it very brittle. Steel making is mainly concerned with the removal of these impurities. This is done by oxidising the elements concerned by blowing pure oxygen through a lance
