Castables for aluminum melting furnaces are suitable for different parts of aluminum melting furnaces in the aluminum alloy industry. They are resistant to aluminum liquid corrosion, anti-penetration, non-sticky to aluminum, and erosion-resistant. Our company's products are made of high-quality silicon carbide, fused corundum, and selected bauxite as the main raw materials, and are refined through scientific proportioning with high-quality additives. This product is comparable to similar products in Japan and has a good response in the domestic aluminum alloy industry.
