Filter box

Our customer had huge difficulties in maintaining temperature of aluminium (at 720 °C) when pouring through its ceramic filter box. This filtration stage couldn’t be done in continuous without seeing aluminium congeal. This compelled him to have important periods of inactivity.

Constraints :

■ Calculation of the additional power necessary to ensure the

maintain of aluminium at 720 °C taking into account the

losses via the ladle radiance.

■ Analysis of the customer’s drawings and characterization of

the right immersion heater to install according to the

application requirements (requisite power, bath level, ladle

dimension).

■ Design of the immersion heater with its heating length, the

appropriate power supply, then manufacture in our workshop.

Gain for the customer :

Continuous filtration of aluminium is now possible, leading to a considerable gain in time and in production cost.
