Filter Principle

◆ According to the quality requirements of molten aluminium, the lining prefabricated parts of the filter box are made of corresponding high-quality castables. After high temperature pre-sintering, they have the characteristics of high strength, scour resistance, erosion resistance, no slag formation, and no sticking to aluminium.

◆ Here are multiple layers of thermal insulation materials with good thermal insulation between the steel structure and the lining prefabricated parts. 

◆ The Deep Bed Filtration Box uses alumina balls and grit sintered by a special process as the filter medium.
