4) Easy to operate, suitable for all casting process.
Single furnace melting time can be as fast as < 40 minutes! power factor of the furnace is always reached the highest state (≧0.96)!
During the smelting, no matter how the furnace condition changes, the medium frequency power supply always full power output. That is to say, without the operator manual adjustment, the whole process from smelting to the end , the intermediate frequency power supply will always be able to deliver the maximum power to the furnace.
Extremely competitive energy consumption index (cast iron about 530 kwh/T)! Compared with common parallel inverter power energy saving about 20%.
Achieve international harmonic current and voltage allowable value!
Using full-wave rectifier power supply series, in the whole working process of the rectifier is always in a state of full open (equivalent to a diode rectifier), do not produce higher harmonic, basic no pollution to power network, does not affect the operation of substation reactive power compensation capacitor.
firs-class induction coil design can effectively reduce coil losses.
The induction coil loss of medium frequency coreless melting furnace accounts for 25% of the total power, so the scientific and rational design of the coil is particularly important. When designing the coil, we adopts the high quality TU1 anoxic copper in aluminum copper, and the coil joint adopts high silver brazing, which has high conductivity and small loss. To Ensure the best spacing of turns, the insulation materials are implanted between turns, the insulation level is improved and the maximum electric thermal efficiency is obtained.
Stable & Environmental Protection
High standard component selection to ensure the stability of the equipment.
①Imported high pressure carbon-free hose and 304 stainless steel clamp: durable!
②Optical fiber transmission inverter trigger pulse signal plate: strong ability of anti-interference and stable operation
③The high quality special heavy platform Thyristor、square type water cooling radiator(HengYang Patent No. ): use more convenient ！
④Customized capacitor: horizontal structure, safer insulation outer shell, using the high strength of the magnesium aluminum alloy, more anti-corrosion and more durable.
⑤Conductive copper bar: Large, thick copper can reduce heat loss and save energy! Copper sandblasted surface and anti-oxidation coating, the contact surface is more conductive, the appearance does not fade and makes more beautiful!
⑥Isolation (exchange) switch : when the furnace is replaced or overhauled, it is possible to control the power failure of one furnace without affecting the normal operation of another furnace. The design of safety and humanization.
⑦Plate heat exchange system (HengYang Patent No. ): to ensure the cooling water temperature in the equipment, and to prevent the external hard water from entering the power . Care to minimize equipment failure.
Medium frequency coreless melting furnace using whirlwind and side suction heat- preservation furnace cover, dust hood (ring) through a certain air absorb dust, waste gas generated in smelting, reach and improve the effect of exhaust emissions, to meet the requirements of environmental impact assessment design.

※ The capacity of the medium frequency coreless melting furnace is based on the density of steel 7.8 (the density of aluminum is 2.7, so the aluminum of equal weight: the matching power is the same, and the capacity needs x 3 times the furnace body)
※ The melting time and tons of power consumption have important relationship with the equipment matching power, raw material shape, raw material density, worker proficiency,
※ In the form above,the “ton power consumption (kwh/T)” is a new series of power consumption, which will consume 15% or more of the power supply in Common parallel IF power supply
※ Equipment configuration: medium frequency power supply, capacitor cabinet, furnace body (steel shell or aluminum shell), hydraulic station (or reducer) tilting system, water cooling cable etc;
※ The Above is the standard product data, can design different power according to the user demand, non-standard product with different melting speed .
