The rotary hearth furnace is used primarily for gear hardening type applications that require process quenching, hardening, pre-heating, normalizing.

Rotary Hearth Furnace

Application Range:

In the aerospace industry and automotive industry, drop-bottom furnaces are typically utilized because of the need for very tight temperature control, fast quench times and rapid heat-up. 

Quick quench drop bottom furnace is electrically heated and designed for installation above the floor level.

Drop Bottom Furnaces are used where transit time to the quench is very short.

These furnaces meet stringent MIL specs and aerospace requirements.

Structure description:

Rotary Hearth type heat treatment equipment, variable speed hearth. Silicon carbide heating elements are utilized electrically heated version.

The heating elements are mounted vertically around the outer wall of the furnace. Terminal connections in an enclosed box below the furnace. Elements are removable from the top of the furnace.

Manual or electric operated door(s).

Temperature control and Recorder

Carbon control with oxygen probe.

Gas flowmeters for dissociated ammonia or exothermic atmospheres.

Nitrogen-methanol atmosphere system.
