Quench Systems
Extrusion Water Quench’s
Water-Wall Style
The Belco Flood Quench is a standing wave-style water quench located at the press exit between the leadout table and the runout table. The standing wave-style quench allows the extrusions to be fully immersed as they travel through the trough. Spray nozzles are also located along the sidewalls of the trough to allow spray quenching on small, lightweight extrusions instead of running the full water wall. The independently controlled spray zones allow the operator to adjust the amount of spray based on the extrusion being quenched.
Intensive Quench
The Belco Extrusion Spray/Flood/Mist/Intensive Air Quench is a combination fully enclosed high-pressure water spray/low pressure spray mist quench unit located at the press exit for cooling the aluminum extrusion profiles. The quench allows multiple types of quench media to be applied as needed for the variety of extrusion profile shapes and speeds for excellent control of cooling on sides, top and bottom.
Extrusion Air Quench’s
Duct Cooling
Duct Cooling
The Belco Duct Cooling System consists of a main run of duct, outlet nozzles and a supply fan which blow high volumes of cooling air onto the extrusions.
Under Table Fans
The Belco Under Table Cooling Fans are designed for high-velocity air on hot extrusions. The fans have a propeller-type blade and are designed to tilt in two (2) directions. The fans have a personnel guard on each side. Allen-Bradley variable speed drive will control the fan output air volume.
Frequently Asked Questions
What types of quench does Belco build?
Water quenches, in water-wall (flood) and intensive styles, and air quenches, using duct cooling or under table fans.
How does the flood quench work?
The Belco Flood Quench is a standing wave-style water quench sitting at the press exit between the leadout table and the runout table. The standing wave allows extrusions to be fully immersed as they travel through the trough, and spray nozzles along the sidewalls allow spray quenching on small, lightweight extrusions instead of running the full water wall.
Can quench intensity be adjusted for different profiles?
Yes. The spray zones are independently controlled so the operator can adjust the amount of spray based on the extrusion being quenched.
What is the intensive quench used for?
It is a fully enclosed combination high-pressure water spray and low pressure spray mist unit at the press exit. Multiple types of quench media can be applied as needed for the variety of profile shapes and speeds, giving control of cooling on the sides, top and bottom.
What air quench options are available?
The duct cooling system uses a main run of duct, outlet nozzles and a supply fan to blow high volumes of cooling air onto the extrusions. Under table cooling fans deliver high-velocity air, use a propeller-type blade, tilt in two directions, carry a personnel guard on each side, and have fan output air volume controlled by an Allen-Bradley variable speed drive.
