Physical Properties of Pressureless Sintered Silicon Carbide Ceramic Products
Silicon carbide ceramic burner sleeves are ideal flame-resistant kiln tools for roller kilns, tunnel kilns, shuttle kilns, etc., and are a suitable replacement for imported products. They are especially suitable for the ceramics, glass, chemical, and metallurgical industries. Available in two temperature ranges: 1650℃ and 1380℃. Used in conjunction with burners, they ensure complete combustion and effectively control kiln cross-sectional temperature differences, ensuring uniform temperature.
