China Suppliers Factory In-Furnace Rotary Flux Injector for Enhanced Metallurgical Processes
Introduction
Purpose
The HO-2000 in-furnace rotary flux Injector is primarily used for degassing and refining molten aluminium in melting and holding furnaces. Compared with artificial pipe refining method, it can reduce labor intensity and ensure the refining effect. Through automated operation, the equipment effectively removes hydrogen and inclusions from the molten aluminum, improving the physical properties and machinability of castings. It is an essential refining device for achieving high-quality molten aluminium refining.
Refining Principle
Hydrogen has high solubility in molten aluminum. If not removed in time, it will significantly affect the performance of the castings. The equipment uses a high-strength rotating rotor to evenly disperse inert gas into fine bubbles, which are evenly dispersed and buoyed in the molten aluminum. Since the hydrogen partial pressure in the aluminum liquid is higher than in the bubbles, and the hydrogen will diffuse into the inert gas and float up to the liquid surface with the bubbles, thereby effectively reducing the hydrogen amount in aluminum liquid. At the same time, the floating air bubbles will bring the fine inclusions in the molten aluminum to the surface of the molten aluminum, which will be captured and removed by the covering agent.

Frequently Asked Questions (FAQ)
What is the primary function of the HO-2000 Injector?
The HO-2000 in-furnace rotary flux Injector is mainly designed for degassing and refining molten aluminium in melting and holding furnaces, replacing manual pipe refining methods to improve efficiency and safety.
How does the refining process remove hydrogen?
It utilizes a high-strength rotating rotor to disperse inert gas into micro-bubbles. Because the hydrogen partial pressure in the molten aluminum is higher than in the bubbles, the hydrogen diffuses into these bubbles and floats to the surface to be removed.
What kind of cost savings can be expected?
The system reduces refining flux usage by 20%, minimizes temperature loss to save 1-2 m³ of natural gas per ton of aluminum, reduces oxidation and burning losses by 40%, and reduces labor requirements by up to 95%.
What type of gas is required for operation?
High-purity nitrogen or argon gas is required, with a purity level of ≥99.996%. The working pressure is adjustable between 0.1 and 0.6 MPa.
Can the rotor speed and refining time be adjusted?
Yes, the rotor speed is frequency-conversion adjustable from 100 to 400 r/min, and the refining time can be set anywhere from 0 to 99 minutes.
