A HYDRAULICALLY OPERATED LABORATORY FURNACE WITH RESISTANCE THERMOMETER TEMPERATURE CONTROL

Abstract

A high-temperature, rapid-loading furnace was constructed for study of small specimens in a controlled atmosphere. The furnace muffle consists of a vertical 36-in.-long, 1.5-in.-diam Zircotube; the tube is necked down at the upper end to fit the tubing for gas supply. This muffle is surrounded by 8 Globar heating elements placed in a circle inside an 8-in. fire-clay muffle which is surrounded by light MgO. These components are contained in a metal drum 21.5 in. high and 18 in. in diam. The furnace also has a hydraulic lifting device and an automatic temperature controller. Introduction of a sample at elevated temperatures does not affect the temperature of the furnace. The apparatus is easily and rapidly manipulated by 1 man.
