process parameters are crucial to a magnesium delivery system. At Metamag our
products incorporate all of the critical functions of the delivery system into
one main processor and operator interface. Besides the fact that much needed floor
space is saved, we are not able to see how a system could be call “Turn
Key” if each component of the melt cell has its own control panel. This
latter would make communication between the equipment practically impossible,
and would tend to become confusing when problems would arise.
Metamag
controls are located in one cabinet, which uses an operator interface with a function
key pad. All data, temperature parameters, pump outputs, and cell monitoring are
made simple and are in one location. The sophisticated program, that is the heart
of the integration, controls the anticipative portion of the program that allows
the bath temperature to increase before an ingot is charged, eliminating temperature
swings. The program controls the functionality of the Preheater to ensure proper
sequencing of all the components.
The Metamag Transfer Pump is
also controlled with the cells PLC program. This ensures proper communication
between the die cast machine, furnace, and pump controls. In order to guarantee
repeatability, we designed our pumps to utilize a vector drive and dynamic braking.
These make the response time between pour time and pour speed almost immediate.
The operator interface also provides a trouble shooting guide that pin points
the problem and instructions the operator how the fix the problem.
