Two units of filtration of aluminium melt (filter box) with the size of 12 inches with combined heating UFP 12M

Task:

Filtration of aluminium melt from non-metallic inclusions through the ceramic foam insert in the line of aluminium ingot production

Customer:

RUSAL Krasnoyarsk JSC, Krasnoyarsk, Casthouse No.1, conveyors No.1 and No.2

Project Year:

2015

Issues prior to implementation:

  • Complicated casting start-up with filter porosity more than PPI20

Key Features:

Power of the radiation heaters is 10 kW (900°С)

Power of the convection heater is 8 kW  (550 °С)

Pneumatic lifting drive

SIEMENS automatic equipment

Result:

Warming-up of the filtration chamber cartridge up to 600°C and warming-up of the ceramic foam insert prior to casting

Possibility of quick start with filter porosity up to PPI50

Change over to SiO2 based concrete

Improvement of production process automation
