Abstract Welcome to the 21st Century and the future of the integral quench furnace. The future means safer processing, simple, yet advanced automation, and environmental compliance, all with the proven performance of low pressure processed component parts. The future furnace combines the benefits of low-pressure vacuum carburizing (LPC) technology with atmosphere integral oil quenching. The future means less gas usage, tighter process control, better temperature uniformity, effortless hardening and increased productivity at a highly competitive price point. Added benefits are seamless annealing, normalizing, stress relief, and high temperature hardening processes.
