Quenching is a heat treating process used to strengthen and harden metal by heating the material to a temperature above its recrystallization phase before rapidly cooling it down. There’s evidence of blacksmiths practicing quenching as far back as the Iron Age, but, as you can imagine, quenching methods have changed drastically over the years.
Keep reading to learn about advancements in quenching and how today’s integral quench furnace can benefit your metal.
Traditional integral quench furnaces feature atmosphere-tight heating chambers that keep parts in a controlled environment throughout the heat treating process. They have a low initial-investment cost and allow for high-volume output of metals.
However, these machines heat metals with an open flame, posing a significant fire hazard and presenting air-quality hazards from carbon monoxide. They also need to be run 24/7 to maintain the appropriate atmospheric levels, which can really run up the energy bills.
The next type of integral quench furnace eliminated oil in favor of high-pressured gas to quench the metals inside the furnace. Vacuum processing reduces impurities in the metal while optimizing metallurgical properties.
The biggest downside of vacuum processing is the high cost of the machinery compared to atmosphere furnaces. Vacuum processing is typically restricted to the medical and aerospace industries, where uncompromised quality is a must.
Today’s integral quench furnaces
The newest type of integral quench furnaces combine technology used in a traditional oil quench tank and a low-pressure vacuum-carburizing chamber. Today’s models are capable of annealing, neutral hardening, carburizing, carbonitriding or performing any other heat treating process much faster and more reliably.
Nowadays, an integral quench furnace doesn’t have an open flame, so there’s a reduced fire hazard and no environmental concerns. These machines feature strategically-located heat sources to provide rapid heat transfer with the lowest possible energy usage. With obstruction-free chambers, the latest integral quench furnaces are also capable of handling much larger workloads than their predecessors.
