Induction furnaces use electromagnetic induction to heat and melt metal such as silver, gold,platinum, iron,steel,zinc, platinum, bronze, aluminum, copper, brass,and silicon for a variety of industrial purposes. These furnaces deliver clean, energy-efficient melting capabilities through controlled processes, and are capable of reducing production losses. Induction furnaces also reduce dust and other pollutants generated by industrial processes.
1, Fast Melting speed , melting temperature is uniform, the oxidation loss is less, and the metal composition is uniform.
2, Strong adaptability , flexible usage in melting. In the medium frequency induction furnace, the molten steel can be completely pour out of the furnace, change the melting material is convenient.
3,Adopt Excellent coil design and high quality thick wall copper tube, the reasonable optimization of design parameters which make the induction coil conversion efficiency the highest, the minimum resistance, more energy can be used in smelting, and our induction coil is not easy to cause damage due to the arc and expansion force.
4, The solid coil support system makes every coil tightly locked, eliminating inter turn short circuit, and overcoming the driving force of electromagnetic force, which can greatly prolonging the service life of lining.
5, The lining leakage alarm system is installed in the bigger capacity furnace, not only to detect the leakage of the furnace, but also can connect the high pressure to the ground to ensure the safety of the operation.
6,Aluminum Shell furnace body , reasonable structure, low cost;steel shell furnace furnace body with The magnetic yoke which can concentrate the magnetic field around the coils to generate thgreat melting efficiency. Steel Frame Furnace Body:
1), Cooldo Induction Melting Furnace are available in capacities ranging from 1.0T to 60 Tons. 2), These Induction furnaces are ruggedly built with heavy structural steel for trouble free operation under harsh melt shop conditions. 3), Thick walled rectangular coil sections are used to minimize coil losses. The higher coil efficiency ensures energy savings and higher productivity. 4), Special coil insulation prevents inter turn sparking. Coil supports maintain inter turn gap and enhance the rigidity of The coil assembly
The Supply Scope Of the Steel Frame Induction Melting Furnaces:

PLC–controller(OPTIONAL) This censor digital-controller should be additionally installed into the frequency thyristor converter in order to improve general work process, providing dozens programs storage, keeping archives up- to-date.The display reflect in a real-time-mode all processes information: power (kW), voltage loose (A), cranking voltage (V), capacitor voltage (Hz).
Capacitors Big volume capacitors interconnected and adjust to the equipment power source; Maid of metal frame with capacitors installed above, including terminal blocks and pipes for the cooling liquid.
Melting unit (hydraulic) Compose of steel frame with the hydraulic bias and induction coil. The coil is installed upon the steel frame and insulated with high-temperature materials that protect the coil from the concrete lining and overheating of the material.
Exhausting fan (OPTIONAL) It is installed upon melting units with hydraulic, and has additional hydraulic fluid power with the control panel. It is used to exhaust gases and steams (toxic).
Hydraulic station Compose of pumps, valve system and control panel, connected with the hydraulic bias control panel.
Hydraulic bias control panel of the melting unit Manages the bias angle of the melting units and provide smooth movement of the hydraulic system of the melting units
Lining displacing/changing mechanism (OPTIONAL) It is used to change the lining quickly; it is compose of hydraulic pushing cylinder. This mechanism drastically reduces lining change process.
Water cooling cable Flexible and firm cable to connect melting unit with the capacitors batteries that power up the coil and cooling it with the liquid simultaneously.
Power Supply Features Of Induction Melting Furnace:
1), The power start-up way adopts frequency scanning zero-voltage soft start mode 2), The constant power control board which can monitor the variation of voltage and current automatically improves melting efficiency! 3), There is only one turn on/off switch and one power adjustment knob for easy operation. 4), Power supply is designed with reliable circuit protection, the electrical components work in a safe range,decrease the damage rate and increase the life obviously
Furnace Body Feature:
Mainly comprises a furnace body frame(steel structure)、furnace mouth、operation table、hydraulic cylinder、induction coil、magnetic yoke、bricks, etc. with the advantage of the following:
1), The steel furnace is popular for foundry and steel plant, The melting capacity range is from 1T—60T
2), The structure is welded by the high strength steel. It prolongs the working life of system.
3), The magnetic yoke of the steel shell can concentrate the magnetic field around the coils to generate the great melting efficiency.
4), The induction coil is not easy deformed in the protection of the magnetic yoke. 5), The hydraulic titling system supports the furnace body to let them more reliable with the fixed pouring position.
