Principle

In a coreless induction furnace, the cylindrical induction coils extend around the refractory crucible, covering 80% of its height. As the entire furnace volume is subjected to the electromagnetic field, the metal inside is heated and melted. Coreless induction furnace can work at higher power densities. A key advantage is that the metal within the furnace undergoes vigorous inductive stirring.

our metal induction melting success case

Medium frequency induction furnace project

The solution provided to our customer is a 1250 kW, 1.5 ton medium-frequency induction melting furnace, which includes the following parts:

1. One power supply : 1250 kW series-type medium-frequency power supply (6-phase, 12-pulse configuration).

2. Two furnace bodies, each with a rated capacity of 1.5 tonnes. The furnaces can operate simultaneously. one is for melting while the other maintains the melting temperature.

3. One 1500 kVA rectifier transformer is to supply power to the medium-frequency power supply.

4. One 300 L hydraulic station system is to power furnace tilting, as well as lid rotation and lifting operations.

5. Two closed-circuit water cooling towers: a 40 t/h unit is for cooling the medium-frequency power supply, and a 100 t/h unit is for cooling the two furnace bodies.

6. Open-type steel-shell furnace bodies are equipped with multiple leakage alarm system.

7. Local control console and furnace tilting control console include auxiliary equipment, such as a furnace lining push-out device, crucible form, and necessary safety devices.

8. A networked melting management system is consisted of a management computer, digital control boards, a main control PLC and a mobile app. The system supports expansion via industrial switches and interfaces with the plant-wide industrial IoT, enterprise management systems, remote diagnostics, engineering maintenance systems, and three-level network architectures.
