Mill coolant system design
What kind of coolant system you construct for your tube mill or roll forming operation is just as important as what type of coolant you use.
Coolants are used to wash away oils, oxides, slivers, and dirt generated during the forming, welding, and sizing of tubes and roll-formed profiles. These coolants are a mixture of water and refined chemicals that help cleanse the process, protect part finish, extend tool life, and inhibit rust and corrosion on the profile and machine.
Typical applications of these coolants include pre- and postpunch operations, roll forming, weld zone flushing, impeder rod cooling, weld scarf removal, profile cooling, sizing, and saw-type cutoff.
The high-volume, medium-pressure, continuous flow of water and chemicals over tools and workpieces creates large volumes of impurities such as sludge and oil that must be removed to prevent contamination of the coolant and tool/profile interface. These contaminants are removed continuously by batch purification processes.
By knowing a variety of mill specifications and production parameters, you can design a flood coolant purification system to meet or exceed the necessary requirements. Such a system could include a pump; fluid transfer hardware; a fluid containment reservoir; water purification, filtration, and oil skimming equipment; temperature controls; and dilution control (as necessary).
