Development of a gas-fired high temperature (2350f) heat treating furnace. Phase 1. Final report, December 1988-November 1990

Based on input from earlier work, the objective of Phase I, the current phase, is to develop the critical subsystems for a high-temperature gas-fired furnace, capable of processing work now done in electrically-fired vacuum furnaces. Computer heat transfer modeling techniques have been utilized to develop the proposed ceramic radiant tube arrangement in the heating chamber which will provide rapid heating rates with military specification temperature uniformity. A test furnace has been constructed and is currently being used to run ceramic radiant tube performance characteristics.
