A bolt is a type of fastener consisting of a head and a screw (a cylindrical body with external threads), which needs to be mated with a nut. Its formation requires a series of complicated processes, such as heating, forging, grinding and so on. In this series of processes, the most important process is heating, which is the basis for other processes to be carried out. For bolt heating, many manufacturers now use super-audio frequency induction heating equipment, and the effect is very good.
In the past, people mostly used coal furnaces, resistance furnaces, etc. to heat and heat bolts. Not only the heating effect is not good, there are defects such as oxidation and decarburization, but also the operation process is very complicated, requiring a lot of manpower and material resources. Now, super audio frequency induction heating equipment is available. Once it came out, it has been favored by many heat treatment manufacturers for its good heating effect and simple operation.
The super-audio frequency induction heating equipment is used to heat and heat-treat the bolts. The heating speed is very fast, and the required temperature can be reached in a short time, which avoids the occurrence of oxidation and decarburization, ensures the heating quality, and prepares for the next forging work. A good foundation has been laid. What's better is that the heating method of the equipment is very flexible, which can be used for overall heating or local heating, which can meet different requirements of customers.
