International Classification:

C21D 9/00

US Classification:

266249

Abstract:

A furnace heats through both infrared radiation and convective air utilizing an infrared/purge gas design that enables improved temperature control to enable more uniform treatment of workpieces. The furnace utilizes lamps, the electrical end connections of which are located in an enclosure outside the furnace chamber, with the lamps extending into the furnace chamber through openings in the wall of the chamber. The enclosure is purged with gas, which gas flows from the enclosure into the furnace chamber via the openings in the wall of the chamber so that the gas flows above and around the lamps and is heated to form a convective mechanism in heating parts.

Abstract:

A ring assembly manufacturing apparatus ( ) and method provides heat to a ring ( ) such as a polymeric ring from an infrared source ( ). A ring assembly ( ) includes a ring ( ) and a hub ( ) within the ring. The ring ( ) is traversed into a chamber ( ) such that the ring ( ) is exposed to infrared energy from the infrared source ( ). The infrared energy causes the ring ( ) to expand thereby facilitating assembly with the hub ( ).
