2. Characteristics of the new sintering process

(1) Rapid heating and uniform temperature

New sintering processes often use medium frequency induction furnaces for sintering. The medium frequency induction furnace has the distinctive feature of fast heating speed and can reach the required sintering temperature in a short period of time. This not only improves production efficiency but also reduces energy consumption. At the same time, the internal temperature of the material in the medium frequency induction furnace is uniform. This is because the principle of induction heating causes the molecules inside the material to be heated by electromagnetic induction at the same time, thereby avoiding the temperature gradient that may occur in traditional heating methods. Uniform temperature distribution helps the material form a more uniform and dense crystal structure to avoid stress concentration, thereby improving the magnetic and mechanical properties of permanent magnet materials.

(2) High efficiency and energy saving

The new sintering process excels in terms of efficiency. Due to the fast temperature rise and short sintering time, it can complete the sintering process in a shorter time than traditional sintering furnaces. This not only improves production efficiency but also reduces energy consumption. The characteristics of high efficiency and energy saving enable enterprises to reduce costs and improve competitiveness in the production process. At the same time, this is also in line with the current development trend of energy conservation and environmental protection and contributes to sustainable development.

(3) Combination of rapid cooling and tempering

In the new sintering process, the rapid cooling and tempering processes after sintering play a key role in improving product quality. Rapid cooling can quickly cool down the material and inhibit grain growth, thereby obtaining a finer and more uniform grain structure. Tempering can eliminate residual stress inside the material and improve the toughness and stability of the material. Through the combination of rapid cooling and tempering, the comprehensive performance of permanent magnet materials has been significantly improved. Hangzhou Magnetic Juli Technology Co., Ltd. makes full use of this process feature to continuously optimize the production process and provide customers with high-quality permanent magnet material products.

3. Key factors of permanent magnet material quality

(1) Effect of temperature

Temperature plays a crucial role in the performance stability of permanent magnet materials. The magnetic properties of permanent magnet materials change with temperature. When the temperature increases, the remanence and coercive force of permanent magnet materials usually decrease. This is because rising temperature will cause changes in the magnetic domain structure inside the permanent magnet material, thus affecting its magnetic properties. In addition, temperature changes may also cause thermal expansion and contraction of the permanent magnet material, causing stress, which further affects its performance stability. Therefore, during the production and use of permanent magnet materials, the temperature must be strictly controlled to ensure stable performance.

(2) Magnetic field and mechanical stress

Magnetic field strength, direction and mechanical stress also have an important impact on permanent magnet materials. The strength of the magnetic field directly determines the degree of magnetization of the permanent magnet material. When the magnetic field intensity increases, the degree of magnetization of the permanent magnet material also increases, thereby improving its magnetic properties. However, too high a magnetic field intensity may cause irreversible changes in the magnetic domain structure of the permanent magnet material, reducing its performance stability. The direction of the magnetic field also affects the performance of permanent magnet materials. Different magnetic field directions will cause the magnetic properties of permanent magnet materials to show different characteristics. Mechanical stress also affects permanent magnet materials. When a permanent magnet material is subjected to mechanical stress, its internal crystal structure may deform, thus affecting its magnetic properties.

(3) Oxidation and impurities

The impact of oxidation and impurities on the quality of permanent magnet materials cannot be ignored. Oxidation causes an oxide layer to form on the surface of the permanent magnet material, reducing its magnetic properties. In addition, the presence of impurities will also affect the performance of permanent magnet materials. Impurities may damage the crystal structure of permanent magnet materials, causing a decrease in their magnetic properties. Therefore, in the production process of permanent magnet materials, strict anti-oxidation measures must be taken and the purity of raw materials must be ensured to improve the quality of permanent magnet materials.

(4) Magnetization process and aging effect

The magnetization process and aging effects also play an important role in the performance of permanent magnet materials. The choice of magnetization process will directly affect the magnetization degree and magnetic properties of the permanent magnet material. Different magnetization processes will cause the magnetic properties of permanent magnet materials to show different characteristics. The aging effect means that the properties of permanent magnet materials will change after a period of use. Aging effects may cause the residual magnetism and coercive force of permanent magnet materials to decrease, thus affecting their performance stability. Therefore, when selecting the magnetization process and using permanent magnet materials, the influence of aging effects must be considered to ensure stable performance.
