Refractory Silicon carbide kiln shelves for pottery pot and ceramic
1. Description
We are a special manufacture of producing refractory products.Utilizing the character of silicon carbide,such as high temperature tolerable,solid strength,good heat conductivity, shock resisting,high thermal radiation,we produce high grade silicon carbide kiln shelf.
The thin silicon carbide kiln shelf not only compress the volume of the kiln but also increase the capacity of kiln and the quality of the products and shorten the production circle.They distinguishes clearly from the other products both on appearance dimension and inner quality of carborundum board in China at present.The products can endure long time without deforming,cracking,dusting.They are especially used for high-grade sanitary ware and detailed ceramic products because of not polluting the color of the products.
The carborundum board are ideal materials for producing sanitary ware,Ceramic products,Porcelain insulators,Abrasive,Glass,Chemical industry,Cement,Electricity factory and so on.
2. Application
Our Silicon carbide kiln shelves can offer high mechanical strength at high temperature, excellent heat stability, good distortion resistance at high temperature and oxidization resistance. It can be used in high class washing basin, high-class bowl and bowl urinal. Through the burning of 1300° C, it provides high enamel and high abrasion resistance. It can keep gloss and quality for 10 years. Our brand enjoy good reputation in this trade. We are improving our product and introducing green into our sales activity.
