Heat treating involves three distinct steps
- high temperature heating or austenizing, rapid cooling or
quenching to harden, and tempering for final hardness and
physical properties. Each step is significant in its effect on
To fill the need of quenching equipment for
the general shop, MIFCO has developed industrial type units
for tool room, vocational education and metals technology.
They have powerful agitator circulating pumps, separate quench
chamber with catch basket, and electric heaters and
temperature controller as optional equipment.
The shop rule for calculating quench-tank
capacity is one gallon of quench media, for each pound of
steel quenched at 1500°F per hour. The sixty gallon capacity
of the powered units provides ample volume for the average
Standard quench oils give best results when
heated to 120° F to 140° F. The oil quench tanks are immersion
electrode heated and have automatic temperature control.
Special high temperature oil can also be used at 300° to 400°
for hot oil quenching. Water quench tanks are usually
maintained at 60° to 70° by addition of tap water and are
built with tap inlet and overflow.
A Jominy Hardenability Test End Quench
Fixture is available for vocational and metallurgical
laboratory work. It is a portable, integral unit and is used
with the QT-200-A system or comparable size tank. The support
stand, end quench chamber, flow nozzle and support ring are
rust resistant stainless steel or brass. The pump is 110 volt,
60 cycle with flow adjusting valve and cord.
