Introduction: The Significant Position of Super Teeth
Elaborate on the crucial role of super teeth in crushers, introduce the significance of surface hardening treatment processes in enhancing their durability, and attract readers’ interest.
First, the working principle and challenges of super teeth
(1) Brief description of Working principle
Introduce how the super teeth of the crusher come into contact with and crush the materials during operation, and clarify its working mechanism.
(2) Common Failure Forms
This paper analyzes the failure problems such as tooth surface wear and tooth root fracture that occur during the operation of super teeth due to wear, fatigue, impact, etc., laying the groundwork for the subsequent discussion on surface hardening treatment.
Second, in-depth analysis of surface hardening treatment process
(1) Detailed Explanation of Traditional Craftsmanship
1.Carburizing process
This paper introduces the principle of carburizing process, explaining that it enhances the hardness and wear resistance of the tooth surface by penetrating carbon atoms into it at high temperatures. However, it elaborates that it has disadvantages such as uneven hardened layer and large internal stress.
2. Nitriding process
This paper explains that the nitriding process allows nitrogen atoms to integrate into the tooth surface to form a hardened layer, demonstrating that it can enhance the hardness, anti-seizing property and corrosion resistance of the tooth surface. At the same time, it points out the problems of the shallow hardened layer and high brittleness.
3. High-frequency quenching process
This paper expounds that high-frequency quenching uses induced current to rapidly heat the tooth surface and then cools and hardens it. It introduces its fast heating speed and high production efficiency, and analyzes its limitations such as uneven distribution of the hardened layer on the tooth surface and large deformation.
(2) Exploration of New Processes
1. Laser phase change hardening
This paper introduces laser phase transformation hardening, which rapidly heats and self-cools the tooth surface by scanning with a high-energy laser beam, demonstrating that it can enhance the hardness, wear resistance and fatigue strength of the tooth surface. It also analyzes the shortcomings of high equipment cost and relatively shallow hardened layer.
2. Shot peening combined with rapid cooling
This paper explains that in shot peening, high-speed shot colliding with the tooth surface causes plastic deformation, introducing residual compressive stress to enhance fatigue life. It also demonstrates that combining rapid cooling with liquid nitrogen can reduce internal stress and lower the risks of deformation and cracking.
Third, the principle of enhancing durability through surface hardening treatment
(1) Increased hardness
It is indicated that surface hardening increases the hardness of the tooth surface, enhances its resistance to material wear, and prolongs its service life.
(2) Residual compressive stress effect
It is expounded that the residual compressive stress offsets part of the working tensile stress, enhances the fatigue strength, and reduces the possibility of fatigue crack generation and propagation.
(3) Grain refinement effect
The rapid heating and cooling during the surface hardening process refine the grain size of the tooth surface, enhance the comprehensive mechanical properties, and increase the wear resistance and toughness.
Fourth, key factors for optimizing surface hardening treatment
(1) Optimization of process parameters
Analyze the influence of parameters such as shot blasting pressure, time, distance, laser power and scanning speed on the hardening effect, and emphasize the importance of reasonable parameter selection.
(2) Synergy between pretreatment and post-treatment
Elaborate on the functions of pretreatment such as cleaning and preheating, and explain the significance of post-treatment such as secondary cleaning, inspection, and tempering in ensuring the quality and performance of super teeth.
Fifth, the industry application prospects of surface hardening treatment
Looking forward to the application prospects of surface hardening treatment technology in the crusher industry and other related industrial fields, emphasizing its significant value in improving equipment performance and reducing costs.
Sixth, Conclusion: Surface hardening initiates a new era of durability for super teeth
Summarize the significant role of surface hardening treatment process in enhancing the durability of super teeth, call for attention to and application of advanced processes, and promote the development of the industry.
