Product Overview
Professional Aluminum Melt Refining, Degassing And Powder Injection Station
The SNJL5000 aluminum melt purification treatment station is designed for aluminum foundry workshops that require efficient hydrogen removal, inclusion separation, powder injection and automated furnace-side refining control.
Efficient Degassing Principle
The machine injects preset inert gas into molten aluminum through the rotating graphite shaft and graphite wheel. The rotor breaks the inert gas into a large number of fine dispersed bubbles, allowing them to mix evenly with molten aluminum. These bubbles absorb hydrogen and oxide inclusions and carry them upward to the melt surface.
Fine bubble dispersion improves contact area with molten aluminum.
Hydrogen and inclusions float to the melt surface with rising bubbles.
Spiral slow-rising bubbles help extend contact time and improve purification effect.
Stable Industrial Design
The machine adopts Siemens PLC S7-200 SMART control system. It is stable, reliable, easy to operate and convenient to maintain. The whole machine has strong rigidity, stable high-speed operation and convenient graphite rotor replacement.
Electric lifting baffle prevents vortex formation during degassing.
Manual and automatic operation modes are available.
Ideal for aluminum casting factories requiring reliable melt purification.
Working Principle
How The Degassing And Purification Process Works
01
Gas Injection
Preset high-purity nitrogen or argon is injected into molten aluminum through the rotating graphite rotor system.
02
Bubble Dispersion
The graphite wheel breaks inert gas into fine bubbles and disperses them evenly into the molten metal.
03
Hydrogen Removal
Fine bubbles absorb hydrogen and oxide inclusions through gas partial pressure difference and surface adsorption.
04
Floating Separation
Bubbles rise slowly in a spiral path and carry impurities to the melt surface, improving refining efficiency.
