Quartz Non-stick Aluminum Casting Material

Quartz Non-stick Aluminum Casting Material

Our company has developed technology to add a-Al203 powder and silica fume to the fused quartz content (>60%) to increase the strength and density of the fused quartz castable, and add anti-aluminum liquid infiltration agent to improve the anti-aluminum liquid infiltration.
The refractory material in contact with aluminum liquid should have good chemical stability. The fused quartz castable has good thermal shock stability, small thermal expansion, low volume density, small thermal conductivity, easy to keep warm, and reduce heat loss. It is mainly used in aluminum flow troughs, gates and other parts.

Product features

Refractory materials for aluminum melting furnaces, quartz non-stick aluminum castables, are made of molten quartz as the main raw material, with an appropriate amount of impermeability agent added. They have a strong impermeability effect on Zn, Cu, Mg, and Al in aluminum alloys. The castable has the characteristics of good volume stability, good impermeability, and high strength. It is suitable for use in aluminum flow troughs and other parts that come into contact with aluminum liquid.

 

 

The quartz non-stick aluminum castable series of refractory materials for aluminum melting furnaces are made of molten quartz as the main raw material, with non-stick aluminum additives added. The products have low thermal conductivity, good thermal insulation performance, and excellent thermal shock stability and volume stability. The surface of the material after the castable is smooth, and the addition of non-stick aluminum agent makes the material have excellent non-stick aluminum performance. Quartz non-stick aluminum castables for aluminum melting furnaces are mainly used for aluminum chute, degassing box and filter box. Our company can produce quartz non-stick aluminum castables for aluminum melting furnaces with a density of 1.8-2.2 kg/cm3. According to the frequency of aluminum discharge, aluminum water flow rate and flow rate, we can design quartz non-stick aluminum castables for aluminum melting furnaces with corresponding body density for customers.
