ABSTRACT:
A high temperature long life thermocouple assembly for measuring continuous molten metal temperatures is made from thermocouple protection tube of insulating materials fabricated by rolling to form an open ended tube which resists attack of molten metals by dissolution and oxidation. The tube is plugged from one end, which is the sensing end of the thermocouple, with a plug made of a different material than the tube body and is cemented to the tube. The cement used is a special high temperature mortar which adheres to the plug and the tube. The plug is made of special graphite by infiltrating into it certain corrosion salt inhibitors. When assembled the tube encases the thermocouple protecting it from dissolution and failure upon immersion in molten metal. This device makes it feasible to monitor continuously for days the temperature of molten metals and alloys, in corrosive atmospheres at temperatures as high as 2820.degree. F. The durability and life of the tube is attainable because the tube's resistance to molten metals and its light weight.
