Two units of filtration of aluminium melt
12.07.2018Task:
Filtration of aluminium melt from non-metallic inclusions through the ceramic foam insert in the line of aluminium wire production
Customer:
Krasnoyarsk Metallurgical Plant LLC, Krasnoyarsk, melting and casting unit No. 2
Project Year:
2017
Problems prior to implementation:
- Lack of filtration chamber
- Application of asbothermosilicate plates for lining
- Open melt overflows
Key Features:
Power of the radiation heaters is 10 kW (900°C)
Power of the convection heater is 16 kW (550°C)
Pneumatic lifting drive
SIEMENS automatic equipment
Warming-up of chambers alternately by moving cover
Result:
- Warming-up of the filtration chamber cartridge up to 600 °C with radiation and warming-up of the ceramic foam insert prior to casting
- Reduction of non-metallic inclusions
- Change over to SiO2 based concrete
- Improvement of production process automation
