Silicon carbide non-stick aluminum casting material is a high-performance refractory material specifically developed for aluminum and aluminum alloy smelting and casting processes. Its core feature is that it can effectively prevent the wetting and adhesion of molten aluminum or aluminum melt, while also possessing excellent high-temperature resistance, corrosion resistance and mechanical strength.
Non-stick Aluminum
Silicon carbide non-stick aluminum casting material exhibit low surface wettability, resulting in a large contact angle between molten aluminum and the surface, reducing aluminum adhesion and penetration, simplifying cleaning, and preventing aluminum contamination. They possess strong anti-penetration capabilities due to their dense structure and low porosity, effectively preventing molten aluminum from penetrating into the material's interior and avoiding the formation of an aluminum-refractory interface reaction layer, thus reducing nodule formation and adhesion at the source. They are easy to clean; even small amounts of molten aluminum residue can be removed through simple mechanical cleaning or high-temperature melting, reducing maintenance complexity.
High Temperature Resistance
Silicon carbide non-stick aluminum casting material can withstand long-term service temperatures above 1400℃, and can withstand the high temperatures during aluminum smelting and intermittent high-temperature shocks. They have a low coefficient of thermal expansion, and through matrix design, can reduce cracks caused by sudden temperature changes, ensuring structural integrity.
Corrosion Resistance
It can resist the chemical corrosion and physical erosion of molten aluminum and aluminum slag, extending its service life. Silicon carbide has high chemical stability and does not easily react with aluminum or aluminum oxides at high temperatures, preventing the material from being dissolved. Molten aluminum can erode refractory materials during transportation or stirring. This castable, due to the high hardness of silicon carbide aggregate, dense matrix, and excellent wear resistance, can reduce erosion losses.
Convenient Construction
As a castable, it can be constructed by pouring, vibration and other methods, adapting to complex furnace shapes, and has a dense structure after hardening.
