Information

What is the necessity and principle of sprockets quenching? Follow the editor of duplxe roller chain wheel sprocket to understand it briefly!
Sprockets quenching is that some parts (including sprockets) are subjected to alternating loads such as torsion and bending, and impact loads during work, and its surface layer bears higher stress than the core.


In the occasion of friction, the surface layer is continuously worn. Therefore, the surface layer of some parts is required to have high strength, high hardness, high wear resistance and high fatigue limit. Only surface strengthening can meet the above requirements. Because surface quenching has the advantages of small deformation and high productivity, it is widely used in production. The purpose of sprockets quenching is to transform the supercooled austenite into martensite or bainite to obtain a martensite or bainite structure, and then temper it with different temperatures to greatly increase the strength, hardness, and resistance of the steel. Grindability, fatigue strength and toughness, etc., so as to meet the different use requirements of various mechanical parts and tools.
Place the workpiece in an inductor wound with a hollow copper tube. After passing in the medium frequency or high frequency alternating current, an induction current of the same frequency is formed on the surface of the workpiece, and the surface of the part is rapidly heated (the temperature can be increased by 800~ in a few seconds) 1000 degrees, the core is still close to room temperature), immediately spray water to cool (or immerse in oil for quenching) to harden the surface layer of the workpiece.
The above is the introduction of duplxe roller chain wheel sprocket editor: the necessity and principle of sprockets quenching.
