Non-Ferrous Melting

Hangzhou Star Electric Furnace has been of the competent leadership in variety applications of induction melting furnace (Iron & steel melting induction furnace, copper melting induction furnace, aluminum melting induction furnace, silver melting induction furnace, gold melting induction furnace and so on) throughout the foundry industry, supplying the induction furnace body from capacity of 50kg to 90MT and also the solid state power supply system from 50kW to 40000kW.  

As a leader induction furnace manufacturer in China, Hangzhou Star has exported the induction furnace to Europe, South America, Middle East, Latin America and Asia markets. and we are also the biggest induction furnace manufacturer in China.

In 2001: China first 12-pulse 6000kW/8t MF induction furnace.

In 2003: China first 12 pulse 8000kW/12t MF induction furnace.

In 2006: China first 12-pulse 5000kW/10t induction melting furnace..

In 2007: China first 24-pulse 18000kW/40t MF furnace..

In 2008: China first 50kA automatic hydraulic furnace-change switch.

In 2009: China first 15,000kW/40t nickel-chromium alloy melting furnace..

In 2011: China first 24-pulse 27000kW/70t MF induction furnace.

In 2017: China first 24-pulse 36000kW/90t MF induction furnace.

  

Features:

The stable working performance for the SCR inverter with parallel circuit;

The 24-pulse or 12-pulse design control systems for large-capacity power supplies for low harmonic interference;

Power supply with a max. capacity of 36000 kW (the first invention in China);

Advanced design of filter inductor has ensured the safety of SCR safety;

The power factor is 0.95 under all operating conditions;

All-digital control system with high accuracy and self-diagnostics;

Leak detection system with alarm and shutdown function to ensure the safe operation of the power supply;

Easily start and stop the entire control system;

Special rectifier furnace transformer is matched with suitable solid state power supply;

Safety control of the water circuit flow and temperature;

Steel shell furnace body is the best design for induction furnace in the world;

Steel structure design is used for solid furnace body from 50kg to 90MT, with easier access due to the open frame;

Thicker high temperature top and bottom blocks can last longer and stay shape suitable for the furnace;

Low loss water cooled shunts;

Desk type furnace platform;

Lining push-out system can be installed (optional);

Maintenance friendly arrangement.

With the improving energy-saving power requirements of induction furnace, our company has gradually explored the improvement on energy-saving, the features of new energy-saving DC Chock are as follows:

All conductive wire packages adopt aluminum foil winding structure, with no water, no oil cooling, and they are cooled by air (fan is added), commonly known as dry-type smoothing DC Chock. This type of smoothing reactor is used in large-tonnage induction melting furnaces, and the reaction effect is very satisfactory, the energy saving is relatively large, and the energy saving per ton of steel is 20 ~ 40 kWh/t. The dry-type DC Chock has simple structure, no oil, safe and reliable operation, large inductance, good linearity, low noise and small loss, and maintenance-free. However, it is bulky, covers a large area, and has a large magnetic flux leakage range, and large electromagnetic interference to the surrounding electrical equipment and it has high power loss. This DC Chock is particularly suitable for high-power melting customers.
