Abstract
A lance thermocouple of the type used for immersion in molten metal baths is provided with means for cooling by passage of low pressure air through the interior of the thermocouple connector. Radial passageways intersecting with a central bore are provided. Optionally the air or other cooling gas is cooled further by flow through a conduit wrapped with a cooling coil containing cooling water. In accordance with the invention a supply of cooling gas at a pressure less than about 10 PSI is provided to the interior of the lance pole. The hot junction end of the thermocouple is immersed in molten metal while a stream of the cooling gas is caused to flow through the interior of the thermocouple connector, radially outward from the passages and subsequently vented to the atmosphere.
