Factory supply porous foam ceramic alumina ceramic

Foam ceramic filter disc (CERAMIC FOAM FILTER):

Alumina foam ceramic filter applicable tempure1000℃ , suitable for filtration and purification of aluminum and alloy solutions

In order to meet the increasing quality requirements of aluminum castings, alumina foam ceramic filters are used.(Plate)It is becoming more and more important. Filters are also widely used in the casting of ordinary sand-type casting, cleaning, tide-type casting and fixed-type casting, such as automobile aluminum parts casting

The filtration process is mainly based on the following considerations,On the one hand, filtration makes the flow of aluminum orderly and relatively calm. , on the other hand, the solid in the metalThe slag is effectively removed and the casting quality is rapidly improved

Alumina foam ceramic filter products can effectively remove the fixed inclusion in the culture metal, so aluminum alloy can be successfully forged, aluminum foil manufacturing extrusion processing and other processes, and the quality products can be obtained. Products include10ppiCoarse porosity40ppi

1. Foam ceramic filter disc efficacy:
Purified metal melt   Simplified gating system    Improving metallographic structure of castings    
Casting qualification rate  

2. The classification of foam ceramics:

Foam ceramics can be divided into silicon carbide foam ceramics, Alumina foam ceramics, zirconia foam ceramics, magnesia foam ceramics and so on according to their Material.

3. Guide for selection of foam ceramics:

It is very important to correctly select and design the filter type and filter seat according to the casting type and pouring weight. The general principle is that the whole gating system is a pressure-free system to ensure the smooth filling of molten metal. The points are (the ratio of cross-sectional area):

F sprue: F filter front end: F filter rear end: F runner: F inner runner = 1: 4: 1.75: 1.1: 1.2.

4. Storage method:

Store in a dry and ventilated place, free from rain and heavy pressure.

5. Main technical indicators of ceramic foam filter:
