Gas Injection

Users see improved results such as faster processing and better shearing of gas for smaller bubbles.

The gas injection tube has a short tip that minimizes breakage.

An expansion in the base creates a low pressure area which draws the gas into the melt.

When melting a wide range of scrap material, customers may look to directly inject nitrogen, argon or chlorine into their melt to remove elements such as magnesium.

This process can improve furnace productivity by increasing the melt rate by removing magnesium.

By incorporating MMEI’s gas injection method while circulating molten metal, users see improved results such as faster processing and better shearing of gas for smaller bubbles. It’s considered the method of choice when removing magnesium. Utilizing a unique expansion chamber, the pump outlet creates a low pressure area which pulls gas into the metal flow.  Gas enters from bottom into expansion chamber, allowing full flow of metal to shear the gas. Complete mixing of gas occurs inside the pump for maximum metal treatment and optimum efficiency. A tight seal and “pulling effect” is created by the expansion chamber eliminating any gas leakage.

The MMEI patented process has no parts obstructing flow path to be broken by debris.  In the event a service is needed, the tube design makes it easy and fast to replace. Thus limiting downtime and saving overall costs in the gas injection process.
