Heat Treated Forging Tools Get New Quench Tank

HTD Size-PR Logo

A forging tool manufacturer will receive an agitated heated oil quench tank to be used post-heat treatment in order to set hardness. Tools such as nippers and ladles -- critical components in the foundry and in forging equipment -- are heat treated to the required hardness and then quenched in oil to set that hardness.

The L&L Special Furnace Co. small model QTO1224 heated oil quench tank holds 65 gallons of oil and can quench parts from 50 to 75 pounds. The quench tank oil is agitated by an impeller with a ½ HP explosion-proof motor and is heated with a 4.5 kW immersion heater to maintain the oil at a slightly elevated temperature to help eliminate oil flashing and fire potential.
