The main factors determining whether a material is resistant to wear: the hardness of the substrate and the bond strength inside the material

The hardness of the metal is naturally much lower than the hardness of the inorganic non-metallic material, especially when the temperature is raised, the hardness and the bonding strength of the metal material are drastically lowered.

SUPAMIC series of wear-resistant materials, the aggregate is made of silicon carbide, corundum and other materials, has a very high hardness, the base part is made of internationally renowned raw materials, high hardness and high strength.

The traditional cone-expanding flame ring is made of cast steel. The taper and the stabilizing tooth ring are separately manufactured. The taper is composed of four pieces. The main function is: primary air diffusion, which promotes the recirculation zone. However, the expanded cone and the stabilizing toothed ring of the cast steel are not wear-resistant, corrosion-resistant, high-temperature resistant, and have a short service life, resulting in great economic loss.

The silicon carbide hood has high strength, wear resistance, corrosion resistance and high temperature resistance. The hood is uniform in airflow and has a service life of 3 to 5 times that of the cast steel hood, which improves boiler efficiency, energy saving and environmental protection. Our company can produce various types of silicon carbide hoods according to customer's drawings.
