ABSTRACT:
A plant for producing enameled wire using an inline process has, placed in order a wire pay-off system, a wire drawer, an annealer, an enameled dope coater, an enamel processing unit and an enameled wire take-up unit. The annealer and the dope coater are placed together in a single oven housing, which has a drying space, a curing space and a return shaft in which a circulating air blower, a heating unit and a catalyst are placed. The blower is responsible for producing a heated air current moving through the heating unit of the annealer and through the catalyst, the air current furthermore moving in the opposite direction to the direction of the wire through the curing space and the drying space. The wire makes its way through an annealing tube and the return shaft into waste gas pipe joined therewith and through a wire cooler, which is full of inert atmosphere as produced by a unit. After coming out of the wire cooler the wire is moved into the enamel dope coater from which it makes its way into the drying space and the curing space, it coming out of the curing space through a wire outlet and then makes its way into a wire cooler which is right next to the oven housing. From the wire cooler the wire makes its way to the wire take-up system, after being run through plant a number of times. The cooling air for the wire cooler is preheated by a heat exchanger before going into the curing space under gage pressure. Control of air circulation is undertaken by adjustment of the speed of the blower and adjustment of the door, while the temperatures for drying and baking are controlled by the waste gas door.
