Medium Frequency Furnace

1.The mechanical part of the medium frequency furnace consists of the furnace body, water and electricity introduction system, furnace tilting device, etc.

2.The water-cooled cable is crimped with copper stranded wire using cold pressing process.

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

4.The controller is a single-board integrated control board, which adopts digital triggering, has high reliability, high accuracy and easy debugging, and few relay components.

5.Advanced sweep-frequency type excitation and zero voltage starting technology, with a startup success rate of 100%.

6.Automatically follow the load changes, and have non-fault automatic restart function and power automatic adjustment function during operation. It has ideal current limiting, voltage limiting, unique off time or inverter angle control to ensure reliable operation of the equipment.

7.It has a complete multi-level protection system (water pressure, phase loss, undervoltage, overcurrent, overvoltage, off time, direct pass, operation interlock, etc.).

8.It has a high frequency conversion efficiency of 1000Hz and below, greater than 96%.

The medium frequency furnace consists of a furnace body, a furnace shell, an induction coil, a furnace lining, a water and electricity introduction system, a mechanical tilting device (or a hydraulic tilting device), a medium frequency power supply cabinet, a compensation capacitor, a water cooling cable, a connecting copper bus, a reducer, etc.

Furnace body (including furnace frame, furnace cover, sensor, yoke, crucible mold refractory clay, etc.)

Hydraulic system (including furnace tilting hydraulic cylinder, pump, motor)

Water cooling pipe

Water cooling cable

Furnace lining material (quartz sand)

Rectifier transformer Medium frequency power supply cabinet, reactor and capacitor rack

Furnace tilting operation table

Furnace leakage alarm device

Furnace vibration tool

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.
