What is 70KW Medium Frequency Induction Melting Equipment Advantages?
70KW medium frequency induction melting equipment uniform heating, high temperature control accuracy, uniform heating, to ensure that the temperature difference between the core and surface of the heated workpiece is small, and the temperature can be accurately controlled through the temperature control system to ensure product repeatability.
70KW medium frequency induction melting equipment has low energy consumption and high pollution-free heating efficiency. Compared with other heating methods, it effectively reduces energy consumption, has high labor productivity, no pollution, and equipment meets environmental protection requirements.
70KW medium frequency induction melting equipment induction furnace body is easy to replace according to the size of the workpiece to be processed, different specifications of the induction furnace body need to be configured.
Each furnace body is designed with water and electricity quick-change joints, so that the furnace body replacement is simple, fast and convenient.70KW medium frequency induction melting equipment, complete melting equipment protection, the whole machine is equipped with water temperature, water pressure, lack of phase, overpressure, overcurrent, pressure/current limit, start overcurrent, constant current and buffer start, so that the melting equipment starts smoothly and protects Reliable, fast, stable operation.
70KW medium frequency induction melting equipment heating speed is fast, oxidation and decarburization is less. Because the principle of induction heating of medium frequency furnace is electromagnetic induction, the heat is generated by the workpiece itself.
This heating method has a fast heating speed, very little oxidation, and high heating efficiency. The repeatability is good, the metal surface is only slightly decolorized, and a slight polishing can restore the surface to mirror brightness, thereby effectively obtaining constant and consistent material properties.
70KW medium frequency induction melting equipment heating method smelts precious metals with high melting points such as platinum, palladium and gold. The medium frequency power supply can quickly heat and electromagnetically stir the metal to obtain a high temperature and highly uniform molten metal.

Medium Frequency Induction Melting Equipment Working Principle
The working principle of medium frequency induction melting Equipment is to put a metal cylinder in an induction coil with alternating intermediate frequency current. The metal cylinder does not directly contact the induction coil. The temperature of the energized coil itself is already very low, but the surface of the cylinder is heated. To redness, or even melting, and this redness and melting speed can be achieved only by adjusting the frequency and the strength of the current.
A three-phase bridge-type full-control rectifier circuit is used to rectify the alternating current into direct current. After being smoothed by a reactor, it becomes a constant direct current source, and then through a single-phase inverter bridge, the direct current is inverted to a certain frequency (usually 1000 To 8000Hz) single-phase intermediate frequency current. The load is composed of an induction coil and a compensation capacitor, which are connected into a parallel resonance circuit.

The basic composition of the melting furnace?
High frequency power supply (integrated or split), induction coil, crucible.
The basic composition of the intermediate frequency melting furnace:
Including intermediate frequency power supply, compensation capacitor box and furnace body, etc. According to different application requirements, it may also include infrared thermometers, temperature controllers and other devices: melting furnaces are divided into three types: overturned melting furnaces, top-out melting furnaces and fixed melting furnaces. According to the tipping method, the tipping smelting furnace can be divided into mechanical tipping furnace, electric tipping furnace and hydraulic tipping furnace.
Induction heating machine can also use for melting platinum, silver crucible, etc. It’s simple and easy, together working with smelting crucible, especially the graphite crucible and quartz crucible.
