The long bar heat treatment machine controls the heating temperature and improves the quality of the workpiece.
Now, most of the heat treatment manufacturers begin to choose the long bar heat treatment machine for quenching, tempering, annealing, quenching and tempering, and so on. How do you control the heating mode and heating temperature during induction heating? Today, the technicians of Forever will tell you how to control it?
1. Quenching with long bar heat treatment machine–Selection of cooling method. The quenching surface is heated at the same time. After heating, the parts are sent out of the inductor and placed in the cooling system for quenching and cooling. In order to cool well, the quenching medium should be in the state of agitation, and the parts should be rocked at the same time. It is suitable for small batch production.
2.Quenching with long bar heat treatment machine–Selection of heating method. The basic methods of induction heating can be divided into two kinds: Simultaneous heating method and continuous heating.Simultaneous heating means that all the parts surface will be placed in the induction heaters for heating. The continuous heating method refers to the relative motion between the induction heater and the parts during the heating process, and the surface of the part is heated again and again. The selection of heating method is closely related to the power and production mode of the long bar heat treatment machine besides the shape, size and technical conditions of the parts. In mass production, in order to improve the productivity, the method of simultaneous heating should be used as much as possible when the power of the equipment is large enough. 
In single and small batch production, when shaft and rod and large size plane are heated, even if the power of the long bar heat treatment machine is surplus, the continuous heating method is often adopted considering the convenience and versatility of inductor. The determination of the specific cooling scheme depends on the characteristics of the parts, technical requirements and production conditions, which are often considered at the same time as the design of the inductor.
If the power of the long bar heat treatment machine is not enough, or even if the power of the equipment is redundant, continuous heating method can be used in order to make the hardened layer evenly distributed. In order to make the inductor more versatile and convenient to make in the small batch production, the continuous heating method is also adopted.
