100kg200kg500kg electrotherm induction crucible melting furnace for aluminium, copper melting

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).
2) 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.
3) Melting unit (hydraulic)
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.
4) Exhausting fan 
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).
5) Hydraulic station 
Compose of pumps, valve system and control panel, connected with the hydraulic bias control panel.
6) 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
7) Water cooling cable 
It should be flexible and firm cable to connect melting unit with the capacitors batteries that power up the coil and cooling it with the liquid simultaneously.
8) Crucible for concrete lining 
9)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.

Description:

Cooldo Steel Scrap Melting Furnaceare available in capacities ranging from 1.0T to 60 Tons.

• These furnaces are ruggedly built with heavy structural steel for trouble free operation under harsh melt shop conditions.
• Thick walled rectangular coil sections are used to minimize coil losses. The higher coil efficiency ensures energy savings and higher productivity.
• Special coil insulation prevents inter turn sparking.
• Coil supports maintain inter turn gap and enhance the rigidity of The coil assembly

Power supply parameters

Power Supply Features Of Steel Melting Furnace:

• The cabinet adopts the GGD structure from German

• The power start-up way adopts frequency scanning zero-voltage soft start mode 
• The constant power control board which can monitor the variation of voltage and current automatically

•     improves melting efficiency!
• There is only one turn on/off switch and one power adjustment knob for easy operation. 
•  Power supply is designed with reliable circuit protection, the electrical components work in a safe range,
•    decrease the damage rate and increase the life obviously

Safety Protection Function:

•   The main circuit short circuit protection
•   SCR overvoltage protection
•   Main circuit phase fault protection
•   Cooling water temperature protection
•   The main circuit phase loss protection
•   Low water pressure protection
• SCR over-current protection
•  Furnace leakage protection
•  Intermediate frequency power failure protection
•  Intermediate frequency electric furnace fault protection

Furnace Body Feature:

Mainly comprises a furnace body frame(steel structure),furnace mouth,operation table,hydraulic cylinder,induction coil,magnetic yoke,bricks, etc.  See below.

 About the steel furnace for foundry and steel plant, The melting capacity range is from 1T—60T

  The structure is welded by the high strength steel. It prolongs the working life of system.

  The magnetic yoke of the steel shell can concentrate the magnetic field around the coils to generate the 

    great melting efficiency.    

  The induction coil is not easy deformed in the protection of the magnetic yoke.

  The hydraulic titling system  supports the furnace body to let them more reliable  with the fixed pouring 

    position.
