1 ton steel shell induction scrap iron smelting furnace

Product Description
Medium frequency coreless melting scrap metal induction furnace working principle
No core is provided in the coreless induction furnace. A crucible of more convenient shape can be employed.
In this case, also the charge to be melted is made the secondary of the transformer. The primary is wound over the crucible itself. The eddy currents produced in the charge not only heat it up but also account for the stirring action. It is the basic coreless induction furnace principle.
Iron laminations are provided outside the primary winding to create a low reluctance path for flux and also contain the stray field which may otherwise induce the heavy current in supporting steel structure.
The frequency employed depends upon the size of the coreless induction furnace. For lower capacities of furnaces higher frequency of the order of 3000Hz are employed whereas for higher capacities frequencies are down to 600Hz. To reduce copper losses, hollow copper tubes are used in which cold water is circulated.
The operating power factor of such furnaces is very low (between 0.1 and 0.3). Therefore, static capacitors are used to improve the power factor of the installation.
Since the power factor does not remain constant during the operation of the furnace, the capacitance in the circuit during heat cycle is varied to maintain power factor approximately unity.
The coreless induction furnace is chiefly used for melting of steel and other ferrous metals. The capacities available vary from 250kg to about 20 tons. The initial cost is more as compared to arc furnace.
Advantages of our 1 ton steel shell melting scrap metal induction furnace:Strong and durable, especially for large capacity furnace body, which needs a strong rigid structure from the perspective of tilting furnace safety. The yoke made of electrical steel shields the magnetic lines generated by the induction coil, reduces the magnetic flux leakage, improves the thermal efficiency, increases the output, and safes 5-8% energy;The existence of cyclone dust removal furnace cover reduces the loss of heat and improves the safety of equipment;The cyclone type smoke hood has excellent dust absorption and heat preservation effects and occupies less space. Can be tilted back and forth and can also stay at any position;The cyclone dust hood can effectively absorb dust during the spheroidization process in front of the furnace, which cannot be achieved by the traditional dust hood;Long service life. Aluminum is easy to cause metal toughness fatigue under the high temperature and strong magnetic field environment;The safety performance of the steel shell furnace is much better than that of the aluminum shell furance. The aluminum shell furnace is easy to deform and has poor safety due to high temperature and heavy pressure during smelting. Steel shell furnace uses hydraulic tilting furnace, which is safe and reliable.
