Marine crankshaft forging is an important part of Marine power system, its wear resistance is of great significance to ensure the normal operation and prolong the service life of the ship. This paper will discuss the wear resistance improvement methods and practical exploration of Marine crankshaft forgings, in order to provide useful reference for enterprises.
Wear resistance improvement method
Material selection: Select materials with high strength, high hardness and high wear resistance, such as high carbon steel, alloy steel, etc., to improve the wear resistance of crankshaft forgings.
Heat treatment process: Through a reasonable heat treatment process, such as quenching, tempering, etc., adjust the structure of the material, improve the hardness and wear resistance of the material.
Surface strengthening treatment: The use of surface strengthening technology, such as carburizing, nitriding, shot peening, etc., to treat the surface of the crankshaft forgings to improve its surface hardness and wear resistance.
Structural design optimization: Optimize the structural design of crankshaft forgings, reduce stress concentration and friction and wear, and improve its wear resistance.
In the production process of a ship manufacturing enterprise, the following practical exploration was carried out to improve the wear resistance of Marine crankshaft forgings:
Material selection: The company chose high carbon steel as the material of crankshaft forgings, and optimized its composition to improve the wear resistance of the material.
Heat treatment process: The enterprise adopts advanced heat treatment process, quenching and tempering treatment for crankshaft forgings, adjusting the organizational structure of the material, improving the hardness and wear resistance of the material.
Surface strengthening treatment: The company uses carburizing treatment technology to treat the surface of the crankshaft forgings, improving its surface hardness and wear resistance.
Structural design optimization: The company has optimized the structural design of crankshaft forgings, reducing stress concentration and friction and wear, and improving its wear resistance.
The wear resistance of Marine crankshaft forgings can be effectively improved through the practical exploration of material selection, heat treatment, surface strengthening treatment and structural design optimization. The application of these methods can not only extend the service life of crankshaft forgings, reduce maintenance costs, but also improve the power and economy of ships, and bring economic and social benefits to enterprises. Therefore, enterprises should pay attention to the research and application of wear resistance improvement methods, and constantly improve and optimize the relevant technology and management measures to adapt to the changing market environment and enterprise development needs.
