Furnace: The furnace chamber is heated by four
electric resistance heaters which are embedded in a
refractory material. The chamber is insulated with a
ceramic fiber insulation. The temperature is con-
trolled by an automatic proportioning controller using
a platinel thermocouple to feed back information. The
control is located under the furnace chamber and is
well insulated from the heat generated in the furnace
chamber. The temperature is controlled by one of
three types of controllers.
