The standard TTI Integral Quench furnaces are designed for processes such as Annealing, Carburizing, Clean hardening and Carbon nitriding. Each furnace is equipped with a variable speed fan to conserve energy.
The casing of the furnace is cylindrical in shape and provides the following unique features.
- The circular flow path provides uniform atmosphere circulation over the work as well as the radiant tubes, ensuring superior temperature uniformity and carburizing rates.
- The round casing is structurally stronger than conventional square casing and is less susceptible to warping and distortion.
- The insulating refractory is 13 ½" thick to reduce heat losses and increase operating efficiency. The refractory is installed as a continuous arch with proper expansion joints. The arch is the strongest possible refractory shape. The volume of refractory is less compared to a rectangular wall construction, minimizing the heat storage that must be supplied as the furnace is brought to operating temperature.
- As well as providing uniform atmosphere circulation for convection heating, the cylindrical construction tends to focus the radiant energy stored in the refractory on the center of the work being heated.
