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 final results.

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 shop.

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.
