EFRS-250

Electrotherm develops and manufactures In-House Fluxless magnesium recycling solutions for the magnesium die casting industry. Recognising both the financial benefits in using recycled materials and the increasing industrial concern for environment welfare, Electrotherm offers an oppurtunity to benefit from a new recycling system. The system allows to employ a clean recycling process and to place the recycling operation adjacent to the die-cast machines. The process, enables high purity, chloride free primary quality material.

EFRS-250 successfully recovers 93% of Class A1 scrap with a prime material quality. 

Electrotherm Fluxless technology is a viable and effective recycling solution for both convrntional alloys such as AZ91D and AM60 as well as new alloys containing alkaline and rare earth elements.

The system includes the following components:

  • Preheating system
  • Melting furnace
  • Process furnace
  • Ingot casting conveyor
  • Shielding gas system

  • ASTM B93-94
  • GMw3035

​Preheating System

  • special low watt density high temperature tubular heating elements located in an external box
  • one centrifugal blowerblows the air upon the Mg scrap surface in the descending direction of the conveyor.

Melting Furnace

  • 7 panels of heating elements are located on both sides of the crucibles for easy replacement.

Process Furnace

  • 6 panels of heating elements located on both sides of the crucibles for easy replacement

Ingot Casting Conveyor

  • Casting capacity - 250 Kg/Hr
  • Ignotize - 6 or 8 Kg
  • Chain pitch - 184 mm
  • Overall size - 5550 mm
  • Moulds no. - 50

Shielding gas system

  • the choice of gas mixture option is subject to the customer's requirements. 

  • Minimum chlorine content
  • Assures high quality alloys 
  • Operation near the die cast m/c: short loop material supply 
  • Prevents environmental corrosion to plant structure and equipment 
  • Tight control on scrap
  • No outsourcing (saves workmanship and transportation).
  • Inventory reduction
  • Saving energy consumption
  • Lessens maintenance costs
  • Stabilizes process
  • Standard operation for high yield
  • No need for metallurgist intervention
  • Minimum alloying material
