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
