10 Ton Induction Furnace

There are two main types of 10 ton induction furnaces, the 10-ton parallel induction furnace, and the 10-ton one-tow-two induction furnace.

1. 10 Ton One-driven-two Induction Furnace

The 10-ton two-driven medium-frequency furnace system is used for the production of steel castings and iron castings. It is composed of a set of no less than 6000KW dual-power variable frequency power supply, two 10-ton coreless steel shell medium-frequency furnaces, and auxiliary equipment required for the normal operation of the system.

A series resonant double output power supply with two electric furnaces can work simultaneously (commonly known as one driven by two), that is, the output power can be randomly distributed between the two furnace bodies in a stepless manner, and the power can be transmitted to the two furnace bodies at the same time, one for heat preservation and the other for smelting.

The power cabinet and furnace body use their own closed-circuit circulating water system, including a closed-circuit cooling tower, heat exchanger, etc. The rectifier transformer uses the primary high voltage to reduce to the input voltage suitable for the medium frequency power supply, the primary voltage is 10KV, and the secondary voltage is DY11, d0 wiring 12-pulse rectifier.

1.1 Working Mode of 10 Ton Induction Furnace:

1.1.1 One set of furnace body smelting production, the other set of furnace body standby.

1.1.2 One set of the furnace body is smelted and produced, and the other set of the furnace body is insulated at the same time.

2. 10t Parallel Induction Furnace

One set of 12-pulse medium-frequency power supply with the power of 6000 kW is equipped with two 10-ton medium-frequency induction heating furnaces, one for use and one for standby. A 6300KVA special rectifier transformer is used for a 6000KW medium-frequency power supply for the smelting of cast steel smelting furnaces.

Adopt a 6-phase 12-pulse intermediate frequency power supply control system. Eliminate the 5th and 7th higher harmonics, greatly reducing the harmonic interference of the power grid.
The use of a fully enclosed cooling tower can improve the cooling effect of the system and the service life of the equipment, without the need to build a pool.
