Steel rods and pipes are mainly heat-treated using roller hearth furnaces. The high temperature consistency and low energy consumption of these furnaces, normally gas-fired, ensure reproducible quality and short treatment times. The processes used for heat treating non-alloyed and alloyed carbon steel pipes at temperatures between 450°C and 1050°C include stress relieving, recrystallizing, normalizing, soft annealing and spheroidizing in indirectly fired continuous roller hearth furnaces. For the spheroidizing of pipes made from high-carbon ball bearing steel, vacuum vestibules to completely isolate the furnace atmosphere from the surrounding air are essential, at least at the furnace entry. Vacuum vestibules are also needed at the entry and exit of continuous roller hearth furnaces for the bright solution annealing of high-alloy austenitic pipes. In the heat treatment of copper alloy bars and pipes, zinc, which can be easily oxidized, is the critical element in the alloy. Rapid cooling is essential to ensure that the zinc is kept in solution. This can be achieved using optional high-convection cooling chambers with a hydrogen atmosphere.

Wellman's broad experience in building Roller Hearth Furnaces includes direct-fired and atmosphere furnaces for temperatures to 2100°F (1150°C). Fuel-fired or electrically heated designs are available.
These furnaces are ideal for lamination annealing, tube annealing and many other processes. For example, a successful Roller Heath line was provided for reheating molybdenum and tungsten sheets for rolling. It features a unique pulse-fired combustion system.

Depending on the bloom size and capacity, either standard or special-design rotary hearth furnaces are available for heating large blooms.
|
|
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.
