1 The furnace part should have leakage alarm, cooling water pressure loss and cooling water over-temperature alarm and protection measures.

2 The furnace body design must have a furnace lining device with the function of quickly removing the furnace lining.

3 The inductor must be wound on a special tool with a copper tube of the brand T2, and subjected to insulation treatment such as overall dipping, vacuum drying, etc., and the wall thickness of the induction coil is greater than or equal to 5 mm;

4 The tilting system adopts hydraulic type, the oil inlet requires a limited speed shut-off valve, the furnace body tilting trunnion should have a good lubrication device, and provide the first production oil (lubricating oil, hydraulic oil).

5 Hydraulic components Hydraulic parts are made by American company PARK.

6 IF power supply should have protection measures such as overcurrent, overvoltage, phase loss, water temperature and water pressure.

7 The main circuit of the IF power supply should meet the output power knob and can be started at any position, and the startup success rate must not be lower than 99%.

8 Inverter thyristor tubes used in IF power supplies must be manufactured by the British company Sima, and the operating current must not exceed 50% of the rated current of the components.

9 The furnace frame must ensure sufficient strength to prevent a series of problems such as short life of the lining due to deformation. The lower part of the furnace shell is provided with a fixing bracket of the furnace lining mechanism.

10 The yoke is made of high quality cold-rolled silicon steel sheet imported from Japan, δ=0.30mm, low magnetic loss, clamped with stainless steel, and has a good water cooling device.

11 Water-cooled cable connections should be strong and durable, and easy to replace and repair.

12 The die is rolled from a thick steel plate of 6mm or more to ensure concentricity and flatness of the welded surface.

13 The hydraulic pump adopts two-machine dual-pump unit (one set of work, one set of spare). It must have oil filter, electric heater and hydraulic operation console. It can control the tilting of the furnace body in the range of 0-95 degrees and the lining of the furnace. The system works reliably and smoothly, without impact and creeping, the speed is adjustable and can stay at any position.

14 Induction melting furnace body closed circulating water cooling system with water temperature water pressure control and monitoring device and flow monitoring function.

15 Cooling water system: The power closed circulating water cooling system consists of water-water heat exchanger, internal circulating water pump, pressure regulating device, temperature, pressure monitor and water purification interface. Pipes, valves and other devices must be made of stainless steel and copper. production. The internal circulating water pump is two (one for one), which meets the requirements for electrical cooling. A quick shut-off valve is provided at the inlet of the cooling water.

16 The equipment is required to clearly specify the requirements for the cooling water system and the emergency external circulation water supply scheme, the treatment plan in case of power loss in the factory and the required matching requirements.
