TEMPERATURE CONTROL DEVICE FOR OVEN FOR CONTROLLING HEATING AND CURING OF RESINOUS INSULATING MATERIAL

摘要

A temperature control system for an oven for heating and curing a powdered coating of a heat hardenable resinous material that has been applied to coil windings of a magnetic core, including a heating panel on each of two opposite sides of a core, the panels being movably mounted on an oven frame for placement of the panels at suitable distances from the core, the panels having a plurality of infrared radiation lamps adapted to be turned on and off for predetermined portions of the preheating and curing periods, an infrared radiation thermometer mounted on each panel for detecting the temperature of a selected portion of the coating and for controlling the on and off status of the lamps, and the thermometers being pivotally mounted in the corresponding panel for enabling direction of the thermometer to the selected portion of the coating.
