PGM | Protection-Gas-Mixing-Unit

In order to avoid any reaction of molten Magnesium and ambient air, melting furnace is designed and performed with a tight crucible cover and melting bath is protected by gas, which is mixed in the protection gas unit. There, carrier gas as Nitrogen, CO2, Argon is mixed with the

protection gas as SF6, R134a, SO2 in an adjusted quantity and concentration and then supplied to the dosing furnace. An accurate/precise mixture ratio is even guaranteed on fluctuating input pressure, what is an important fact for ensuring safety.
