How does vacuum quenching technology improve the quality of bimetal screws?

In the manufacturing process of bimetal screws, vacuum quenching technology is a crucial process. This technology significantly improves the material structure and performance of screws and enhances overall quality by heating and rapidly cooling the screws in a vacuum environment.

First, vacuum quenching technology enables precise control of the material's processing temperature and time. In the vacuum furnace, by precisely regulating the heating and cooling process, it is possible to ensure that all parts of the bimetal screw are heated and cooled evenly, avoiding temperature unevenness and distortion problems that may occur in conventional heat treatment. This precise control allows the screw's properties to be precisely tuned, increasing its strength and toughness.

Secondly, vacuum quenching technology helps reduce quenching distortion. During the heating and cooling process, conventional quenching methods often cause distortion of the workpiece due to factors such as its own weight, mutual extrusion, and vibration. However, in a vacuum state, since heat can only be transferred through radiation, the heating speed is slow and the temperature difference between various parts is large, which greatly reduces the possibility of distortion. In addition, by taking process measures such as slow heating, preheating, and low cooling rates, quenching distortion can be further reduced and the dimensional accuracy and shape stability of bimetal screws can be ensured.

In addition, vacuum quenching technology can also improve the corrosion resistance and wear resistance of bimetal screws. The surface of the screw after vacuum quenching treatment is brighter, reducing oxidation and decarburization, thereby improving its corrosion resistance. At the same time, due to the rearrangement and strengthening of the material structure, the wear resistance of the screws has also been significantly improved, extending the service life.

Combined with the company introduction mentioned above, we can further understand the importance of vacuum quenching technology in the manufacturing of bimetal screws. For example, a company may focus on producing high-performance bimetallic screws and employ advanced vacuum quenching technology to ensure the quality of its products. Through this technology, the company is able to produce bimetallic screws with high strength, high toughness, high corrosion resistance and high wear resistance to meet the needs of various harsh working environments.
