Product Description

 

 

Induction furnaces are divided into two categories: induction melting furnaces and induction heating equipment. The former is used for melting or heat preservation of materials, and the charge is finally in liquid state; the latter is used for heating materials, including uniform heating of the whole material, surface heating or local heating.

An induction furnace is an electric furnace that uses the induction electrothermal effect of the material to heat or melt the material. The main components of an induction furnace are sensors, furnace body, power supply, capacitors and control system.

In addition to heating or melting in the atmosphere, induction furnaces can also heat or melt in vacuum and protective atmospheres such as argon and neon to meet special quality requirements.

Induction furnaces have outstanding advantages in heat permeation or melting of soft magnetic alloys, high resistance alloys, platinum group alloys, heat-resistant, corrosion-resistant, wear-resistant alloys and pure metals. Induction furnaces are usually divided into induction heating furnaces and melting furnaces.

The equipment consists of a 750KW intermediate frequency power cabinet for melting, a capacitor cabinet, two 1.0-ton steel shell induction furnaces, two 500 square meter water-cooled cables, a set of hydraulic tilting furnace devices, a tilting furnace operation console, a 900KVA rectifier transformer, a closed cooling tower, etc.

Our Advantages

Electrical section description
 This technical solution is a series connected one electric two furnace configuration, suitable for melting steel materials. The intermediate frequency power supply is configured with 6 pulse 300KW/1KHZ. The complete equipment consists of a 315KVA 3-phase 6-pulse rectifier transformer, a KGPS300KW/1KHZ single rectifier parallel inverter intermediate frequency power supply, two 0.5t steel shell electric furnace bodies, a set of compensating capacitor banks, two sets of hydraulic tilting furnace systems, a set of water-cooled cables, a set of enclosed water cooling systems, etc.
 

Rectifier transformer

  1. Power rectifier transformer (user provided):
The power rectifier transformer is used to reduce the high voltage 10KV to a suitable voltage of 380V for the intermediate frequency power supply. The intermediate frequency equipment adopts a dedicated rectifier transformer and oil immersed self cooling method.
The rectifier transformer adopts a 6-pulse form according to the rectification method of the intermediate frequency power supply.

 Parameters of rectifier transformer:

Electric furnace capacity(t)	Intermediate frequency power supply power(KW)	Transformer capacity(KVA)	Voltage combination		Connection group label	Impedance voltage(%)
			One side(KV)	Secondary side(V)
0.5	300	315	10	380	Y,d11	6~8

Note: There should be an no-load tap changer on the high voltage side of the original transformer, with voltage regulation in three levels: -5%, 0%, and+5%.
 

 Medium frequency power cabinet

 The rectification trigger circuit adopts a digital circuit, which is characterized by rectified pulses and particularly accurate trigger angles. Due to the use of three-phase synchronous signals and digital filters, the external power grid voltage and frequency phase sequence changes can be triggered without errors. If a single-phase signal divider is used, it is difficult to achieve trigger consistency for phase sequence changes, resulting in poor real-time performance and transformer heating. The given voltage for adjusting the pulse phase shift is controlled by a voltage controlled oscillation counter, ensuring the consistency of the phase shift positions of 6 pulses. At the same time, the speed of pulse phase shift blocking is increased from the original analog circuit phase shift speed of milliseconds to microseconds, ensuring the reliability and safety of the high-power intermediate frequency power supply device, current and voltage protection. Therefore, if the slot circuit short circuit or overvoltage protection is in operation, the reliability of our company's intermediate frequency power supply reaches 100%.
The digital scanning starting trigger is adopted, and the circuit adopts advanced phase-locked loop frequency and phase detection technology, which can ensure the reliability of the entire system's tracking and locking circuit operation. At the same time, it has good anti-interference ability against the strong electromagnetic waves and interference signals emitted by the frequency dependent intermediate frequency electric furnace, ensuring the normal operation of the inverter system.
The control system adopts advanced technology circuits with dual closed loops of current and voltage, making it particularly stable and reliable throughout the entire operation process. It can be reliably and stably used in response to changes in the power grid, severe changes in loads, and impact changes.
