When molten aluminum comes into contact with refractories, it can react and cause sticking, build-up, and erosion on the refractory surface. Non-stick aluminum castable is formulated to minimize these issues and provide a smooth, non-reactive lining that resists adhesion and build-up of molten aluminum.
This type of castable typically contains a combination of refractory aggregates, binders, and additives that provide a low-wettability surface for molten aluminum. The formulation may include materials such as high-alumina aggregates, silicon carbide, or other specialized additives that enhance the non-stick properties.
Key characteristics:
Non-reactivity: It resists chemical reactions and adhesion between the castable and molten aluminum, preventing sticking and build-up.
Low porosity: Non-stick aluminum castable has low porosity to minimize molten metal penetration into the lining, reducing the risk of adhesion.
Thermal shock resistance: It can withstand rapid temperature changes and thermal cycling, which are common in aluminum processing operations.
Erosion resistance: Non-stick castable resists erosion caused by the movement and flow of molten aluminum.
Non-stick aluminum castable is typically installed as a lining or coating in various aluminum processing equipment, including furnaces, ladles, crucibles, and transfer systems. It helps to prolong the service life of the refractory lining, improve process efficiency, and reduce downtime associated with refractory maintenance and cleaning.
The way castables are used also determines the quality of the project. Our company has a professional engineering team, welcome to consult.
