ANNEALING DEVICE FOR IRON CORE OF ELECTRIC APPARATUS

摘要

PURPOSE:To enable reduction in the length of a quartz furnace core on the inside of an induction heating coil and to reduce the size of an installation with a device for conveying an iron core in the furnace core pipe by a chain conveyor by supporting the furnace core pipe by the above-mentioned coil itself. CONSTITUTION:Quartz guide rails 6 consist of one piece each which has a large diameter and is symmetrical to the center line in the bottom of a furnace core pipe 2 and the rail having a small diameter in the central part thereof. An iron core 7 is placed on a chain conveyor 5 above said rails and is moved in a heating coil 1. All the rails 6 are fixed to the pipe 2 by welding at several points at prescribed intervals. The pipe 2 is continuously supported in the longitudinal direction in the bottom X of the coil 1. Since the need for an intermediate supporting table of the pipe 2 is eliminated, the disposition of the coils 1 in tight contact with each other in the longitudinal direction is made possible and the reduction in the size of the installation is possible.
