L&L Special Furnace Ships an Agitated Heated Oil Quench Tank Used for Quenching Various Tool Steels
L&L Special Furnace has shipped a small model QTO1224 heated oil quench tank for quenching heat-treated tools used in the forging industry. The tools include various styles of equipment used in the forging industry. Tools such as nippers and ladles are very important parts of foundry and forging equipment. Forging is the heating of the steel to a malleable state or liquid and can be formed or poured into required shapes and tools. The tools are heat-treated in a furnace to the required hardness and then quenched in oil to set hardness.
The quench tank holds 65 gallons of oil and is ideal for quenching 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. There is also a safety lid with fusible links that closes automatically if the fusible links melt, dropping the lid and blocking exposure of the surface of the oil to air to prevent any potential fire.
The quench tank has a Eurotherm digital overtemperature protection. This shuts the heater off if the temperature is above a set level. The overtemp will not allow the heater to operate until the overtemp has been manually reset and the oil temperature is below the programmed setpoint.
This small, versatile quench tank is available in various sizes and can be equipped with quench coolers, baskets, and production elevators for pneumatic quenching as required. The quench tank can also be put on casters for portability.
All L&L furnaces can be configured with various options and be specifically tailored to meet your thermal needs. We also offer furnaces equipped with pyrometry packages to meet ASM2750 and soon-to-be-certified MedAccred guidelines.
Options include a variety of control and recorder configurations. A three-day, all-inclusive startup service is included with each system within the continental U.S. and Canada. International startup and training service is available by factory quote.
