REFRACTORIES

PROCESSES:

• Firing: Temperatures from 750°C (1,380°F) to 1,850°C (3,360°F). Attention paid to temperature uniformity as well as fuel consumption.
• Curing: Temperatures from 150°C (300°F) to 350°C (660°F). Air movement and volatile removal are essential and exhausts generally need to be treated with afterburners or RTO units.
• Tempering: 350°C (660°F) to 750°C (1,380°F). Air movement and volatile removal are essential and exhausts generally need to be treated with afterburners or RTO units.
• Nitriding: Special conditions are created around the product within a refractory retort mounted on the kiln cars.
