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.
