Introduction to Haitu Complete Induction Heating Automation Equipment

Induction heating equipment

The induction heating device is a three-phase power frequency alternating current, which is rectified into a direct current, and then the direct current is converted into an adjustable current, and an alternating current flowing through the capacitor and the induction coil is supplied to generate a high density in the induction coil. Magnetic lines and cut gold in the induction coil

It is a material that produces a large eddy current in the metal material. In the technology Shanghai European electrical technology put a metal cylinder in the induction coil with alternating intermediate frequency current, the metal cylinder is not in direct contact with the induction coil, the temperature of the energized coil itself is very low, but the surface of the cylinder

It is heated to redness or even melt, and the speed of redness and melting can be achieved by adjusting the frequency and current. If the cylinder is placed in the center of the coil, the temperature around the cylinder is the same, and the cylinder does not generate harmful gases when heated and melted.

Strong light pollutes the environment.



Brief introduction of complete induction heating automation equipment

Analog control induction heating equipment:

Main control circuit adopts, analog circuit control, 0~5V power adjustment, such equipment disadvantages: poor temperature control accuracy, IGBT zero-crossing control is not good, core power components consume large power, easy to damage, the main circuit often follows the workpiece Change device does not work in resonance state, output efficiency

low. It is only used in places where the heating temperature is not high, and it has been eliminated in the society.



Intelligent automatic induction heating equipment:

A new generation of intelligent induction heating equipment: digital circuit control, high temperature control accuracy, IGBT zero-crossing point is precisely controlled in the switching state, the main circuit resonance frequency is automatically tracked, and can automatically adapt to the load according to the change of the workpiece to ensure that the circuit is in resonance state, so that the whole device lose

Very efficient. Achieve fully automated biochemical processes.

Intelligent induction heating equipment has the following characteristics:

One: control core: generally adopts the world's most advanced high-speed digital signal processor (HDSP), and uses a dedicated chip as an auxiliary processor.

Second: Inverter devices generally adopt high-efficiency fast resonance control mode, the inverter efficiency is greater than 95%, and the host power factor is greater than 0.9.

Third: The equipment has a design structure combining air cooling and water cooling.

Four: Control mode: All-digital high-efficiency fast resonance, can adapt to various parameters of the sensor, smart device power supply generally built-in digital PID temperature control module.

Five: With IO interface: analog output, analog input, IO output and IO input interface, communication interface.

Six: The communication interface can be connected to a dedicated data logger.

Seven: Power adjustment adjustment mode: stepless adjustable, can be adjusted from 0% to 100%, resolution is 0.1% grade or 0.01% grade, output stability can reach 0.3% or 0.025%.


Intelligent automatic induction heating equipment features:

Constant power output, faster melting speed and more obvious power saving effect.

Zero-voltage sweep software is started, which is more suitable for frequent start-up requirements.

The protection measures are comprehensive, such as overcurrent, overpressure, current limiting, pressure limiting, water shortage, and lack of equal protection. Under the premise of ensuring the melting speed, the equipment is reliable.

Simple to operate, suitable for a variety of casting processes.
