Continuous roller hearth furnaces are typically designed to process high volume products that require the same
process time and temperature. Parts are loaded in containers that are specifically designed for the furnace, and
in many cases the parts being processed. The heat treat containers travel through the furnace via a conveyor
which is PLC controlled. Continuous furnaces have multiple zones of control, which typically consist of
entry/heat-up zones, soak zones and an exit zone. The furnace controls are set at a specified cycle time and
solution temperature.
