INTRODUCTION

Principles of Operation

1. 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.
