By using the principle of electromagnetic induction, a strong current is introduced into the induction coil to generate an induction current inside the charge in the alternating magnetic field, thereby heating the charge to an induction heating device.
1. Medium frequency power supply KGPS-160KW-2.5KHz
2. Water-cooled furnace body
Note: The water-cooled furnace body is divided into inner and outer cylinders, which are made of a whole piece of steel plate. The inner cylinder body is made of stainless steel, and the outer cylinder material is Q235 . The head is made of standard head, the inner head is stainless steel, and the outer head is Q235 . The manufacturing methods and requirements are all in accordance with the provisions of GB150-89

1. Water quality parameters.
Water pressure ≥ 0.2-0.4Mpa.
Effluent temperature < 55 °C
Inlet water temperature < 5-35 °C
Hardness CaO < 10mg equivalent
Acid-base ph = 7-8.5
Suspended solids < 10mg/L
Water resistance > 2.5K Ω
Iron containing < 2mg
2. Pool volume
Multiplied by the total power 4-0.05 take . If space is limited, when the small tank volume, can be added cooling towers. When the volume can be guaranteed, it is better to add a cooling tower to the south of the Yangtze River. North of the Yangtze River, may not be considered properly.
3. Water lift
It should be 1.5 times the distance from the pool to the equipment .
4. Water flow
Multiply the total power by 0.04 .
Induction billet furnaces can heat billets to temperatures ranging from room temperature to over 1200°C.
After the Slab is pulled out from the continuous casting machine,Surface temperature is 750 ~ 850℃.
The melting furnace mainly melting the steel, iron and metal. The equipment is mainly composed of power control cabinet and melting furnace body.
