Product Description
Mixed Hertz induction stirring furnace(MHIS):
steel framed induction furnace body full items include: steel shell induction stirring furnace body, furnace frame, furnace cover, tilting furnace oil cylinder, dust cover with furnace cover and hydraulic cylinder, inductor, yoke, high-pressure carbon-free rubber pipe, furnace mouth and bottom pouring fixed material, a complete set of stainless steel water inlet distributor, backwater collector and clamp, etc., including wall-mounted water inlet and outlet.
Description
Complete steel frame structure design, easy for routine maintenance, large size high thickness H-beam constitute the basic structure of the furnace frame, the overall structure is simple, strong, maximum inclination 95 degrees.
The refractory on the surface of the platform, can protect the furnace and platform will not be deformed when in foundry.
Welded complete steel structure, equipped with appropriate support and clamping parts to fix induction furnace coil and yoke; induction furnace upper end parts can be removed, replace coil more convenient.
Pillars - both sides of the load section steel components, become the furnace's solid support, with a hydraulic tilt axis, the axis moved out, up. Ensure minimum tapping trajectory and reduce energy loss of tapping.
Induction stirring furnace coil
Mixed Hertz induction stirring furnace induction coil specially uses copper bar and tube mixed make.The bars and tubes integrated to one unit together.
Unique Design for melting furnace uniform heating, stirring, resonance effect.
In order to improve inter-turn insulation, temperature resistance and eliminate inter-turn intermediate frequency vibration, etc.
Multi-layer winding of polyimide film, mica tape, and alkali glass filament, and the exterior is potted with organic paint.
It can realize 4 states of positive sequence, reverse sequence, inner stirring and upper leveling, and 1200Hz-2200Hz oscillation. The same furnace and dual frequency can work at the same time.
Alloying induction stirring furnace vibrate coil adopt rectangular copper tubes twisted with copper bars, the coil flat twist type only used in top manufacturer industry.

Yokes
Pohang, or WISCO, Baosteel's silicon steel sheet. Uniformly applied to the brace bolts and provide maximum pressure to the coil to ensure the lining long working life. The yoke is made of high-quality cold-rolled silicon steel sheet. The tolerance of the shearing edge of the silicon steel sheet after processing <±0.1mm. The bending degree after assembly meets the requirements of TB/T4280-93 to ensure the coil and the yoke arc shape precision fit. At the same time, multiple sets of yoke fastening devices are firm and reliable, easy to adjust, and evenly distributed along the circumference; the liner between the yoke and coil is made of multi-layer high-quality insulation material, including multi-layer mica board, multi-layer Ceramic fiberboard.
Formed insulation panels and shorting rings are placed on the top and bottom of the furnace.
The composite leak-proof probe is safe and reliable. When metal liquids invades or is about to penetrate the refractory material and the coil, it automatically cuts off the power and alarms. The composite leak proof probe is an important part of the overall leak protection system. At the same time, it also ensures that the molten iron is grounded to ensure the safety of the operator.
The bottom structure satisfies the requirement of removing the furnace lining by using the lining pushing mechanism. Easy to install and easy to operate.

Power Supply Unit
Induction stirring power supply:
Alloying induction furnace under induction stirring melting working conditions, operate power can be adjusted between 20-450KW, working at the scope of 35-70HZ, under heating situation, three phase power supply switch into single phase working, working power can adjust at the scope of 20-800kw, to achieve uniform heating for the metal liquid.
Cabinet
Single phase vibrate power supply designed operate independently, working frequency 1200～2200HZ,
The single-phase oscillating power supply and the stirring power supply work simultaneously and independently, and the operating frequency is changed by the capacitance. High-order harmonics are often generated during conventional intermediate frequency operation. In order to deal with high-order harmonics, the rectification part of the power cabinet adopts a fully open design and an uncontrollable rectification mode. Under the condition short-circuit capacity of the line is not less than 25MVA, the high-order harmonic components of this system meet the requirements of the relevant voltage level in the national standard GB/T14549-93D. The power factor of the incoming power supply of the alloying furnace in the range of 0 to 100% full power is ≥95%.
