Features:
1.Saving Features
As the heating temperature fast, so very little oxidation, oxidation frequency heating forging burning only 0.5%, gas furnace heating oxidation loss of 2%, 3% of coal-fired furnace, intermediate frequency heating technology and materials, each ton forgings and burning stove saves at least compared to 20-50 kg of steel materials. Its material utilization up to 95%. Since the heating uniform heating, the temperature difference between the minimum core table, so in terms of forging also greatly increases the life of forging dies, forging surface roughness is less than 50um saving technology, frequency heating oil heating proportion of 31.5% ~ 54.3% energy saving, gas heating energy than 5% to 40%. Good heating quality, reduce scrap 1.5%, increase productivity by 10% to 30%, extend tool life by 10% to 15%.
2.Environmental Features
Working environment is superior, to improve the working environment of workers and the company's image, no pollution, low energyInduction furnace and stove,, workers will no longer be compared to the hot sun baked and smoked coal stove, but can reach the targets environmental protection departments, while the external image of the company and establish a future with the forging industry trends.

Copper bar outside induction coil will connect with water-cooling cable. The lining closes to induction coil, which made by burden, the method you can find in related parts below.
Why Choose us?
1,Low power consumption
Large current system made of pure copper as conductive medium, the whole circuit with less resistance. Electrode arm shaped as copper-clad box type, resistance and heat can be reduced efficiently. Reasonable arrange of all conductive systems to minimize the resistance of every circuit.
2,Safety & Stability
Full set of hydraulic driving system equipped with accumulator to ensure stability of facilities in the operation process. Whist, equipments can go on the motion when there any emergency accidents happen.
3,High Power Factor
Our power factory could reach over 98%, which could greatly reduce the capacitor box quantities. However we still equip enough capacitor box quantities, which mean your furnace is much much more efficient.
4.High flexibility & Maximum simplicity of operation
HMI used in electrical automation control, interface simulates the real form of furnace, which make the operation more convenient. Mixing feedstock, charging feedstock, melting, tapping all the commands can be implemented by computer.
5.More Durable
We get 6 thyristors on the left, 8 on the right, so even if one thyristor is damaged, our furnace still could be continued use. But many other factories only get only 4 on the right,the whole equipment cannot be used anymore when one thyristor is damaged.
