Induction Melting Furnace

1) Medium frequency power supply
Highly reliable with several protection levels site fault, excluding any human error factor. It is the main managing element of the whole system, equipped with the timer, heating elements temperature control.

PLC–controller(OPTIONAL)
This censor digital-controller should be additionally installed into the frequency thyristor converter in order to improve general work process, providing dozens programs storage, keeping archives up- to-date.The display reflect in a real-time-mode all processes information: power (kW), voltage loose (A), cranking voltage (V), capacitor voltage (Hz).

Capacitors
Big volume capacitors interconnected and adjust to the equipment power source; Maid of metal frame with capacitors installed above, including terminal blocks and pipes for the cooling liquid.

Furnace body (steel frame or aluminum frame)
Compose of steel frame with the hydraulic bias and induction coil.
The coil is installed upon the steel frame and insulated with high-temperature materials that protect the coil from the concrete lining and overheating of the material.

Exhausting fan (OPTIONAL)
It is installed upon melting units with hydraulic, and has additional hydraulic fluid power with the control panel. It is used to exhaust gases and steams (toxic).

Hydraulic station
Compose of pumps, valve system and control panel, connected with the hydraulic bias control panel.

Hydraulic bias control panel of the melting unit
Manages the bias angle of the melting units and provide smooth movement of the hydraulic system of the melting units

Lining displacing/changing mechanism (OPTIONAL)
It is used to change the lining quickly; it is compose of hydraulic pushing cylinder. This mechanism drastically reduces lining change process.

Water cooling cable 
Flexible and firm cable to connect melting unit with the capacitors batteries that power up the coil and cooling it with the liquid simultaneously.

1:Universal circuit breaker:

Installed in front of the electric cabinet, plays the  role as the Isolation switch funtion  in the power supply line, Equipped with a manual switch, automatic switch, voltage-loss protection, over-current protection function.Can display the current through the digital, can have the function of the  real-time monitoring,if any problems with the equipment,it can cut off the current at once, thus can protect the safety of the transformer.

Safety protection function

1:The main circuit and short circuit protection  2;SCR overvoltage protection 3. Main circuit phase fault protection4 The main circuit phase loss protection5Low water pressure protection 6. SCR overcurrent protection 7: furnace leakage alarm 8 :water temperature  system

Double Control Design

Control lines are completely isolated in a separate area.Effectively reduce electromagnetic interference,which can Keep control room clean and keep in a cool temperature , which Greatly improve the life of the circuit board and system reliability.

Furnace Leakage System

Adopt the Most Advanced Furnace Leakage System in china, In the following circumstances the system will  make judgments, and cut off the power supply1:The Molten Liquid Come through the crucible lining and close the induction coil2:the lining is too wet3:furnace body or the power supply has a low resistance to the ground

Remote control system

The remote control system is placed far away from the furnace body, which can be convenient and safe  for workers, this system with the function of the power control, current control, temperature control , voltage control..etc

Safety earthing switch

Isolate the  rectifier and inverter,Provide security protection for maintenance,In the ground position, both the inverter and the furnace body coil are in a safe place.
