LOCKED BY SERIES

Description

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 quench tank 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.

Additional Features

NEMA 4 ELECTRICAL CONNECTION BOX
All electrical connections are made at one NEMA 4 liquid tight box. An on/off switch is included for the heater and a stop and start button for the agitator. Complete fusing is inside this box. Control voltage is transformed to 120 volts. All interconnections are liquid tight. Customer must connect fused power supply to single point on panel.
WARRANTY
The furnace is warranted for one year except for elements and thermocouples which are warranted for six months. See warranty sheet Q12W.
DRAIN AND COOLING INLET AND OUTLET PIPE
An NPT fitting is welded near the bottom to drain and clean the tank. NPT fittings are welded at opposite corners for future attachment of a quench cooler.
TEMPERATURE GAUGE
A dial type temperature gauge is immersed in the tank through an NPT fitting to read quench temperature. This is angled upward for convenient viewing.
IMPELLER TYPE AGITATION
An impeller type agitator insures proper agitation of the quench media. The horsepower and impeller of the agitator are generously sized for vigorous agitation.
STANDARD AGITATOR MOTOR IS TEFC
The standard agitator motor is a TEFC motor. This is specified for water or polymer quench media. Oil quench media requires the optional explosion proof motor.
THERMOSTATICALLY CONTROLLED HEATER
A removable heater is included to heat the quench media to proper quenching temperatures. Typically this is in the 120F (50C) to 140F (60C) range. The smaller tanks feature a screw-plug heater while the larger units (above 11 K.W.) feature a flange mount heater. The thermostat is integral to the heater.
SEPARATE CHAMBER FOR IMPELLER
The agitation impeller is located in a separate area from the working space. This is separated by a perforated screen to prevent damage to the impeller and as a safety precaution. This section has a bolt on cover.
EPOXY PAINT FURTHER SEALS THE TANKS
A base coat of zinc chromate primer is covered with heavy duty epoxy paint.
HEAVY DUTY DOUBLE WELDED CONSTRUCTION
The tank is made from 3/16” steel (1/4” on Model QT 3648 and above) and completely reinforced. All seams are welded on both sides. Includes lifting provisions.
HIGH WORK CAPACITY
Without optional external cooling these quench tanks are capable of quenching as many pounds per hour as there are gallons capacity in the tank. There is 6” extra in height above the nominal fill level to allow for fluid rise. There are 3” above, below and to each side of the working dimensions to allow for good agitation.

Additional Options

ELEVATORS
The quench tanks can be fitted with a pneumatically operated elevator for lowering the work into the tank. The elevator platform can have rollers to accept cast alloy trays directly from a furnace.
EXPLOSION PROOF MOTOR
Specified if the quench tank is going to be used with oil.
FUSED DISCONNECT SWITCH
Mounted on the NEMA 4 control box.
HINGED SAFETY LID
With fusible link for automatic closing in event of fire.
OVERTEMPEPATURE CONTROL
This shuts off heater. Preset for 175F (80C).
QUENCH MEDIA COOLERS:
A cooler allows greater work load throughput per hour by getting rid of the work load heat more quickly. Two types are available. A pump with a water-to-water heat exchanger is the least expensive and is fine for water or polymer. A oil-to-air heat exchanger is recommended for oil.
SPECIAL AGITATORS
The standard agitator/mixer is designed for water, light polymer and light oil. Special low RPM, large diameter impellers are used for very viscous media.
STAINLESS STEEL CONSTRUCTION
The quench tank is available in 304 stainless steel for use with water without rust inhibitor.
