High frequency induction hardening equipment
Working principle of high frequency induction hardening equipment quenching machine:
Variable frequency induction heating or induction heating is a method to transform the power frequency power supply into a specific frequency power source by using the electromagnetic induction principle to heat metal materials. It is mainly used for metal hot working, heat treatment, welding and melting. This heating technology also applies to the packaging industry (such as medicine, food and other aluminum foil seal), semiconductor materials (such as tensile monocrystalline silicon, automotive glass heating paste metal parts, etc.). The basic components of induction heating system include induction coil, AC power supply and workpiece. According to the different heating objects, the induction coil can be made into different shapes. The coil is connected to the power supply. The power supply provides alternating current for the coil. A alternating magnetic field passing through the workpiece is generated by alternating current of the coil. The magnetic field causes the workpiece to generate eddy currents to heat.
Disadvantages of traditional heating methods:
1 the traditional heating of coal, gas and oil is seriously polluted, and the working environment of employees is bad. 2, coal, gas and oil are slow, uneven, easily deformed, oxidized, and poor in quality. The surface is not smooth and the reject rate is high.
The advantages of induction hardening equipment and high frequency induction hardening equipment are:
It is easy to connect the power supply, the induction coil and the inlet and outlet pipes, and it can be learned in a few minutes. It can start heating when the water is switched on, and the power consumption is less than that of the old type electronic tube high frequency equipment. The power consumption is less than 70%. The smaller the workpiece, the less electricity consumption. The effect is good, the heating is very uniform (the temperature of the parts of the workpiece can be obtained by adjusting the induction ring's density), the temperature is fast, the oxide layer is small, and no waste after annealing. The protection has all the alarm instructions, such as overvoltage, overcurrent, overheating, water shortage, and automatic control and protection. The temperature can be controlled by setting the heating time to control the heating temperature of the workpiece, so that the heating temperature can be controlled to a technical point. The fastest heating speed is less than 1 second (speed can be adjusted). Heating can widely heat all kinds of metal workpieces.
Induction hardening equipment, high frequency induction hardening equipment, small size, good environment, energy saving, safety, no noise, waste gas and dust discharge.
