1. Introduction of Silicon carbide kiln shelf
We are a special manufacture of producing refractory
products.Utilizing the character of carborundum,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.
Silicon carbide kiln shelf is combined with high purity silicon
carbide and ultra fines. Shaped by vibration, made by high
sintering. The SiC platesare oxide bonded silicon carbide based
products, which are used in Kiln Furniture. It is featured with
high bending strength at elevated temperature, good abrasion
resistance, Resistance to thermal shock, high thermal conductivity
and offers a good life.

3. Features of Silicon carbide kiln shelf
Silicon carbide kiln shelf has Excellent Thermal Shock
Characteristics and Corrosion Resistance,it has high strength and
it can keep no bending when firing.
Also it has High Creep Resistance and Superior Wear Resistance.At
the same time, it has High strength, extreme hardness,wear
resistance, high temperature tolerance, corrosion resistance,
oxidation resistance,thermal shock resistance, high thermal
conductivity, low coefficient of thermal expansion.
WE HAVE PROFESSIONAL DETECTING EQUIPMENT
We are aimed to improve R&D and production process and
equipment. Moreover, we cooperate with famous university such like
Liaoning University of Science and Technology, Beijing University
of Science and Technology.
4. Package
We use plywood box & pallet to pack Refractory Silicon carbide kiln
shelf, it is very safe. We have professional logistic company, they
can deliver to any port in the world and they can offer very good
price.
