HIGH TEMPERATURE, AIR ATMOSPHERE, CONTINUOUS FURNACES TO 1700°C (3100°F)

The CM 700 Series furnaces are typically used for air atmosphere applications. However, they are also available for use in pure oxygen or inert atmospheres. The base model includes an external stoker, entrance section, high heat section, a cooling section, and cross feeds with return conveyor. Depending on application requirements other features are added such as preheat sections, binder removal sections, and multiple zone controls.

The furnaces are constructed of heavy gauge steel that is welded and reinforced. All power components and controls are located on the main frame assembly. A very efficient block graded brick insulation package is utilized with high purity alumina brick on the hot face. The hanging  molydisilicide heating elements are easy to replace through the roof section.

When automated the pusher plates (carrier trays) form a train and are pushed through the furnace by an external stoker device. All automation is located outside the heat envelope for ease of maintenance and long life.

Temperature control is by microprocessor based setpoint controllers operating in conjunction with phase angle-fire SCR power controllers and type “B” thermocouples. Independent overtemperature instrumentation is standard.
