Three heat treatment methods for screws
Anchor Bolt , the role of this bolt is to fix the machine on the ground. Because of its strong stability, it is often seen in bridges, mines, railways, highways, power companies, cement plants, automobiles, motorcycles, tower cranes, boiler steel structures, large-span steel structures and large buildings. Screws are one of the important components of the Railway Fastening System , and the hardness of the screws often determines the quality of a mechanical device. The determination of the hardness of the screw is the heat treatment of the screw. There are three kinds of heat treatment methods for screws. Today, I will tell you about the three heat treatment methods of screws. Anchor Bolt 1. Tempering heat treatment: The tempering heat treatment is mainly carried out by induction heating or flame heating. You can use two hardness testers to check the hardness of the screw, and then decide which standard heat treatment to use. The two hardness testers are Vickers hardn...
