Heat treatment technology is a crucial link in the manufacturing process of locomotive crankshaft forgings, which directly affects the mechanical properties and service life of products. Although the traditional heat treatment method can meet the requirements to a certain extent, there are some problems such as low efficiency, large energy consumption and easy oxidation. With the continuous progress of science and technology, some advanced heat treatment technology is gradually applied in the manufacture of locomotive crankshaft forgings. This paper will discuss the application and advantages of advanced heat treatment technology in locomotive crankshaft forgings.
Types of advanced heat treatment technologies
Vacuum heat treatment technology: Vacuum heat treatment technology refers to the heating and cooling of metal materials in a vacuum environment to obtain the required properties of a technology. Vacuum heat treatment technology can avoid the oxidation and decarbonization of metal materials and improve the purity and surface quality of products. At the same time, it can also realize rapid heating and cooling, and improve the efficiency of heat treatment.
Laser heat treatment technology: Laser heat treatment technology refers to the use of high energy laser beam to rapidly heat the metal surface, so that it reaches a molten state after the rapid cooling of a technology. Laser heat treatment technology can form a hardened layer of high hardness and high wear resistance on the metal surface, improve the wear resistance and fatigue resistance of the product.
Induction heat treatment technology: induction heat treatment technology refers to the use of high frequency alternating current in the metal to generate induction eddy current inside the metal for rapid heating of a technology. Induction heat treatment technology can realize local heating, improve the flexibility and efficiency of heat treatment. At the same time, it can precisely control the structure and properties of the metal by controlling the heating temperature and time.
