Some Concrete Achievements

Holding Furnace           
2 chambers, total 2T to maintain in temperature Heaters close to wall and need in power : 200kW
 • 5 immersion heaters dia 55, 40kW each, sheath 1050mm long
 • Lifetime more than 2 years
 • Piloted by a dedicated control cabinet


 Melting Furnace                            
Large industrial melting furnace in term of molten aluminium and immersion heaters smelt solid aluminium and temperature to hold at 750°C while smelting
 • 13 immersion heaters dia 32, 13kW each
 • Innovative industrial electric melting furnace
 • Fully environmental friendly


 Crucible with Dynamic Reheating                    
 • 400 kgs liquid aluminium
 • 4 heaters dia 28mm, 15kW each
 • Reheating from 750°C to 800°C in 10 minutes : confirmed
 • A sensor detecting position of lid turning off heaters power
 • The relevant piloting cabinet
 • Quality of aluminium maintained

Filtration Unit
Flow rate of aluminium at 4T/h and need in maintaining and reheating
 • 3 immersion heaters in horizontal position, offering 9kW each
 • Physical and thermal dimensioning of heaters
 • Proven tightness solution
 • Relevant piloting cabinet

 Furnace with low bath level


Transfer ladle
A ladle of 1200 kgs of aluminium
Temperature losses during transfer furnace/ladle and pouring ladle/mould
Necessity to reheat before pouring into a mould
Keeping quality of aluminium
 • well insulated lid with holes for heaters
 • 3 heaters ø28, 15kW each
 • Reheating from 700°C to 760°C within 6  
minutes - relevant piloting cabinet


 Holding Road Transport Ladle
 • 6T
 • Need in reheating 10°C/h up to 830°C
 • heaters ø32mm, 1400mm long, 15kW each 3


 Replacement of Vault Resistances by Heaters
 • High dynamic
 • Homogeneous temperature
 • 40% less energy consumption
 • 6 immersion heaters, 15kW each
 • Quality of aluminium unchanged, no corundum


Retrofit of Degassing Unit
Replacement of inefficient and expensive graphite heating blocks
Rotors creating high temperature losses & a significant aluminium vortex
Possibility to have chloride and other additives
 • Implementation of 1 heater per chamber, dia 55mm, standing additives
 • Thermal, financial and qualitative efficiency of the solution
 • Small heating length fitting bath level, 11kW each
 • Good dynamic


Upholding During Maintenance
28 vault furnaces  45kW each, with corundum
Aluminium temperature at 665°C
4 hrs to reheat before production restart when temperature falls down to 630°C
 • 1 mobile station « Heat Pack »
 • 1 heater 32 & Ø 55 12,5 kW each
 • Gain 2 hours of maintenance on each 28 ovens, 2 times a month


Maintaining Aluminium Temperature in Launders
 • Low aluminium level
 • Horizontal mounting

Continuous Casting
Heating plugs, furnace for preheating of the plugs
