ข้อดี:

1. Through magnetic stirring, the alloy composition of the metal melt can be achieved to be uniform.

Usually, stirring for 20 minutes can meet the composition uniformity index.

It solves the contact pollution caused by mechanical stirring and the instability of alloy composition uniformity caused by manual stirring due to factors such as skill, physical strength or work attitude.

2. Through non-contact stirring, “contamination” of the melt is reduced.

โดยเฉพาะอย่างยิ่ง, it provides reliable quality assurance for the production of high-purity aluminum and other alloys that require strict control of trace elements.

3. Stirring can be carried out when 1/3 of the melt is in the furnace, which enhances the heat exchange between the melt and unmelted solid materials. It increases the melting speed of solid materials.

Through non-contact stirring, it can increase melting efficiency by 20%, reduce energy consumption by 20%, and reduce metal burning loss by 3-5%.

4. Through stirring, the melt temperature during smelting can be made uniform, and the surface and bottom temperatures of the melt are <4 degrees, which solves the problem of overburning and oxidation caused by local overheating of the melt.

5. Stirring can make non-metallic inclusions and gases escape and improve the purity of the melt.

6. It can reduce the generation of oxidized slag because when the melt reaches above 760, the oxidation and suction of the metal intensify.

Permanent magnetic stirring can make the temperature in the melt uniform and improve the conditions for generating oxidized slag, which can generally be reduced by 20%.

It can reduce the frequency of furnace cleaning and help extend the furnace’s life.

7. The directional flow of the magnet stirrer is conducive to the accumulation of oxidized slag on the melt surface and facilitates slag removal, thus reducing the labor intensity and conditions of workers.

8. Under strong magnetic stirring, the melt is forced to flow, which increases the nucleation energy and nucleation simultaneity of crystal grains in the liquid phase, making the crystal nuclei increase uniformly, which is conducive to the refinement of the alloy structure.

9. The rotating magnetic field generated by the permanent magnet can better solve the problem of uniformity of the chemical composition of the solution.

From the principle of electromagnetic force induced by an alternating magnetic field on metal, it is known that when the rotating magnetic field of the bottom-mounted permanent magnet aluminum-liquid mixer acts on the molten aluminum, there is both a horizontal force and a vertical force;

The rotating stirring effect generated by the magnetic field can fully mix the alloy components of different specific gravity at different liquid levels in the molten aluminum liquid.

The low power consumption of the permanent magnetic stirrer and the long-time stirring mode during the melting process can ensure the uniform chemical composition of the solution.

10. As a high-tech product integrating magnetic, electrical, mechanical and hydraulic technologies, the permanent magnet stirrer adopts an extremely simple and compact overall structure.

The entire equipment consists of only two parts: the main machine and the automatic control system.

The air cooling system on the main unit of the equipment realizes automatic control and requires no maintenance, which greatly facilitates users.
