Depending on the type of charge loading and workpiece geometry, there may be dead zones around the charge not seeing any flow or surfaces exposed to most of the cooling gas. To solve this problem, Ipsen has designed a rotary hearth for vertical furnaces whose speed of rotation can be adjusted in line with cooling requirements. This eliminates uneven gas flow distribution.

Wellman Rotary Hearth Furnaces are useful for a number of processes including forging and forming, hardening, tempering, stress relieving and annealing. Units can be direct-fired or engineered for a controlled atmosphere with your choice of gas or electric heating. Temperature range to 2300°F (1260°C).
Precise indexing of the rotary hearth on Wellman designs is accomplished through a rack and pinion system and variable speed drive. Manipulators or custom designed load/unload equipment can be supplied.
