Regarding how to maintain stable output power of induction heating equipment during the heating process, Zhengzhou Gou's has a unique trick

When we use induction heating equipment to heat treat workpieces, how to maintain a more stable output power during the heating process is a common concern for us. Zhengzhou Gou's has been engaged in the production and sales of induction annealing equipment for more than ten years. It can be said that it is quite familiar with the heat treatment of equipment and workpieces. Today, we will tell you how to maintain stable output power during the heating process.

During the induction heating process, due to the increase in temperature, the workpiece loses its magnetism after passing the Curie point, the load changes, and the heating power will decrease. In this regard, we adopt the following measures to maintain the stability of the output power:

1) The measure taken for the intermediate frequency generator is to add a capacitor during the heating process. Generally, this method is used for large workpieces with long heating times, such as large gears, flywheel ring gears, etc. The method is to add an additional capacitor and a corresponding contactor with an arc extinguishing cover to the quenching machine. When the workpiece is heated to the magnetic transition point, the generator current and power decrease, and the pointer turns in the inductive direction. At this time, the matched capacitance is added, and the generator electricity and power increase by a certain value. This method is called the additional suppressing capacitance method.

2) The measure taken for high-frequency induction heating equipment is to change the load inductance during the heating process. The method is to add an auxiliary inductor. For example, when heating starts, the auxiliary inductor and the inductor are connected in series. After reaching the Curie point, the copper shunt controlled by the spiral coil is inserted into the original bus bar, and the auxiliary inductor is short-circuited. The load matching status changes and the output power can be increased. Before short-circuiting the auxiliary inductor, the heating should be disconnected first.

This is the method we came up with after many experiments, we hope it can help you. The induction heating equipment produced by Zhengzhou Gou's has many advantages such as high working efficiency, environmental protection and energy saving. It is your must-select equipment for heat treatment of workpieces. Moreover, we also have rich theoretical knowledge and practical experience and can provide you with the most reliable assure.
