Principle of steel tube induction heating furnace

The sensor winding is carried out in accordance with the “Inductor Manufacturing Process Code” compiled by our company.

2. The furnace body of the steel tube induction heating furnace is divided into two sets according to different specifications of Φ95-130 steel tubes, each with 6 sets. Φ95-115 steel pipe is a group, Φ115-130 steel pipe is a group.

2.1 The principle of the steel tube induction heating furnace is a high power density heating device, the power density can reach several hundred or even several kilowatts per square centimeter. If no measures are taken, the highly concentrated power will generate a magnetic field leakage to the two ends, causing heating of the roller table; coupled with the dissipation of the magnetic field lines, these factors will increase the power consumption of the furnace body and make the heating effect of the two ends of the furnace body poor. In addition, heating is done by using three power supplies. If they are turned on at the same time, the six furnaces will interfere with each other; this will affect the increase of power supply. This is reflected in the similar equipment we provided for you in 2001. . To this end, we take the following measures:

2.1.1 Para reducir las fugas magnéticas, asegúrese de que el campo magnético no interfiera en la fuente de alimentación de frecuencia intermedia y que la mesa de rodillos y el marco de soporte entre el cuerpo del horno no se calienten, las placas delantera y trasera del cuerpo del horno están hechos de placas de cobre cerradas y el agua está especialmente diseñada para pasar agua en la circunferencia de la boca del horno.

2.1.2 Each set of furnace body is equipped with a powered, height-adjustable steel pipe centering guide structure, which makes the steel pipe easy to enter the furnace, avoids the impact of the steel pipe on the inductor, and effectively extends the service life of the inductor.

2.1.3 La invención de la estructura especial de la placa de la boca del horno antimagnético antes y después del cuerpo del horno pertenece a nuestra empresa.

2.2 The furnace lining adopts corundum tube, the service temperature can reach over 1700℃, and it has good insulation, heat insulation, chilling and heat resistance and impact resistance.

2.3 Hay un orificio de drenaje en la parte inferior del cuerpo del horno de inducción, que puede drenar automáticamente el agua condensada en el horno.

2.4 La longitud del cuerpo del horno es de unos 660 mm.

2.5 The structure of the induction furnace is shown in the figure
