L&L Special Furnace Co., Inc. QT Series QT 7272

The QT Series quench tanks are used for the uniform quenching of hot steels. They may be used with water, light weight polymer, or oil. They are not designed for use with brine. Water or polymer must have rust inhibitors (or else tank must be stainless steel.) Special versions are available for very viscous polymer. They feature proper agitation which insures uniform quench temperatures and disperses the bubbles of vaporized quenchant that form on the surface of the hot parts being quenched. These bubbles, if not dispersed, can cause uneven quenching times which would result in a poorly quenched part. The agitation also prevents localized overheating which, in the case of oil quench media, could cause a fire. The QT Series quench tanks also feature integrated controlled heaters and large inlet and outlet taps for optional cooling systems. An optional hinged lid provides a means to extinguish any potential quench oil fires and to keep quench media clean.
