As manufacturing plants modernize, one goal is to reduce the impact of atmosphere heat treating on the surrounding working environment with respect to ambient temperature, exhaust fumes and vapors. Atmosphere heat treat cells are uninviting to work around because batch integral quench furnaces emit smoke and flames.
A newly introduced Allcase® batch integral quench furnace with a flameless design improves the appearance and environment around atmosphere heat treating equipment. This batch furnace has a vacuum purge in the vestibule and an oil quench to process commercial materials. This design can be integrated into a manufacturing cell at a captive plant since it is cleaner with the absence of flame screens, effluent flames, and smoke.
Vacuum carburizing and high pressure gas quench equipment eliminates flame screens also, but the capital cost is greater, training costs are high, not all materials can be processed with gas quenching, and this equipment does not fit into traditional batch lines.
Details of the new Allcase furnace with flameless design operation and typical cycling of the equipment will be reviewed.
Commercial heat treaters who evaluated low pressure carburizing technology to improve the shop’s environment but don’t like the associated costs should plan on attending this talk.
