What is Furnace-Side Rotary Refining Equipment？

The furnace-side rotary refining equipment is installed on the side or rear of the molten holding furnace and can be used in a one-to-one or one-to-two configuration. It employs a rotary spray method, using a combined purification process of "gas + flux or mixed gas" to remove gases and impurities from the molten aluminum, reduce alkali metals and impurity content, and enhance the purity of the aluminum melt. This improves stirring efficiency, facilitating metal homogenization (alloying and homogenization) and reducing the generation of aluminum dross. Simultaneously, it reduces the consumption of gas and refining agents, minimizes smoke emissions, and enhances the safety and environmental friendliness of the operating environment.

The Economics of Furnace-Side Rotary Refining Equipment

The furnace-side rotary refining equipment boasts strong cost-effectiveness, serving as a valuable aid in energy conservation and emission reduction for aluminum melting and casting workshops. According to customer estimates, the initial investment can be recovered in approximately one year

1.Save 20% on refining agents.

Furnace-side refining utilizes the high-speed rotation of a graphite rotor to disperse nitrogen gas into fine bubbles, ensuring extensive contact with the molten aluminum. This increases the contact time, enhances refining effects, and reduces refining time.

Refining agents are injected into the molten aluminum through the central hole of the graphite rotor. The rapidly rotating impeller disperses the refining agents in the molten aluminum, allowing them to react thoroughly. This significantly improves the efficiency of refining agents, concurrently reducing the overall consumption

2.Save 20% on refining time.

Compared to traditional manual lance refining, the refining time of the rotary furnace-side refining equipment can be shortened by 20% while achieving the same refining effect.

Typical refining time control can be referenced as follows:

-Melting furnaces below 20 tons: Refining time ≥ 20 minutes

-Melting furnaces between 20 and 60 tons: Refining time ≥ 20 to 35 minutes

-Melting furnaces between 60 and 100 tons: Refining time ≥ 35 to 50 minutes

-Melting furnaces above 100 tons: Refining time > 50 minutes

(Note: Due to factors such as furnace type and electromagnetic stirring, the specific time may vary based on experimental results.)

3.Save about 30 RMB per ton of aluminum in gas consumption.

Compared to traditional lance refining, each casting cycle can save approximately 30 yuan in gas consumption per ton of aluminum.

Furnace-side refining has minimal temperature loss due to its full sealing, while manual lance refining involves significant heat exchange when opening the furnace door, leading to additional gas consumption for reheating after each temperature drop. As an example, for a 35-ton furnace at a specific site, the gas consumption may vary depending on local gas prices, refining processes, and furnace types.
