Medium Frequency Aluminum Melting Furnace

1.The mechanical part of the intermediate frequency aluminum melting furnace is composed of the furnace body, water and electricity introduction system, tilting furnace device, etc.

2.Water-cooled cable shall be crimped with copper stranded wire through cold pressing process.

3.The fifth-generation intelligent controller developed for parallel inverter has been widely used in the power supply control of various metal smelting, insulation and induction heating equipment.

4.The controller is a single-board integrated control board with digital trigger, high reliability, high accuracy, easy commissioning and less relay components.

5.Automatically follow load change, with non-fault automatic restart function and power automatic regulation function during operation. It has ideal current and voltage limiting and special turn-off time or inverter angle control to ensure reliable operation of equipment.

6.Perfect multistage protection system (water pressure, phase loss, undervoltage, overcurrent, overvoltage, closing time, straight-through, operation interlocking, etc.).

7.Medium frequency melting has a good electromagnetic stirring effect, which is conducive to the uniform temperature and structure of molten metal, scum and impurities reduction;

8.The frequency range is wide, from 1KHZ to 20KHZ. The induction coil and matched compensation capacitor can be designed by comprehensively considering the melting amount, electromagnetic stirring, heating efficiency, noise during operation and other factors to determine the output frequency;

9.Silicon controlled IF power supply is adopted, with energy conservation of at least 20%;

The intermediate frequency aluminum melting furnace is composed of intermediate frequency furnace rectifier transformer, intermediate frequency power supply, steel shell with magnetic conductor electric furnace body (or aluminum shell furnace body), high-purity graphite crucible, capacitance compensation device, hydraulic device (double-pump hydraulic system, hydraulic tilting furnace oil cylinder) (or reducer furnace), tilting furnace console, water distributor, power supply and capacitance water cooling device, induction coil, furnace lining, water cooling cable, connecting copper bar, reducer, etc.

1.Compact power cabinet design saves land resources and reduces customers' initial investment costs.

2.The yoke is configured on the periphery of the coil to prevent magnetic flux leakage, reduce energy consumption and achieve energy saving.

3.The yoke provides strong support for the coil from the periphery of the coil, thereby stabilizing the life of the furnace lining.

4.The oxygen-free copper tube with a special profile is used, and the melting efficiency is increased by about 2% compared with round and square copper tubes.

5.Cyclone dust hood or annular dust hood for flexible selection and configuration.

6.Acidic, alkaline and neutral furnace materials all use dry powder furnace materials. Cast iron is suitable for acidic furnace materials, cast steel is suitable for alkaline furnace materials such as magnesium oxide, and non-ferrous metals are suitable for graphite crucibles and high-purity alumina furnace materials.

7.The furnace body adopts an earthquake-resistant (Lee 7 standard) structural design, equipped with a special structure yoke and special-shaped coil conductors to achieve safe and efficient operation of the furnace body.

8.Built-in fault detection monitor: Multiple sensors collect equipment operation data at all times, and alarm in time when abnormal conditions occur and cut off the power supply. The human-machine interface automatically pops up the fault content and guides maintenance personnel to troubleshoot and repair the fault.
