Hebei FOREVER electric furnace specialized in providing complete equipment for induction heating

The medium frequency electric furnace manufactured by FOREVER Electric Furnace in Hebei Province can be heated by 300-8000Hz power supply according to the geometric shape and heating technology of the workpiece of different materials. It is mainly used for the heat permeability, reheating and blue quenching of bar, round steel, square steel, steel plate, and so on. On-line heating, local heating, transient, extrusion, hot rolling, pre-shear heating of metallic materials, as well as overall tempering, annealing, tempering of metallic materials, etc.

Hebei FOREVERelectric furnace meets and surpasses customer’s demand and expectation is our forever pursue, when carries on the induction heating, when the temperature is fixed, the relative permeability decreases with the magnetic field intensity increase, the magnetic field intensity inside the conductor is not uniform. From the surface to the center, the relative permeability increases from the surface to the center. In the heating process, because the surface temperature of the heated metal is high and the center is low, the resistivity and the relative permeability of the point on the cross section are also different. Moreover, the current penetration depth of the steel, such as steel after the local point, is increased by seven times compared with that before Curie point. The induction heating equipment produced by the company in order to achieve a higher electrical efficiency of the inductor, reduce the magnetic flux leakage in space, and minimize the gap between the induction coil and the blank. Due to the heat insulation layer and heat resistance layer lined in the induction coil, the gap between the heat resistant layer and the blank is very small, and the heat of the blank is transmitted to the cooling water in the pure copper tube of the coil through the heat resistant layer and the heat insulation layer.
