YUFENGREC® Refractory Sagger Kiln Furniture can be made of top quality alumina , corundum,mullite , Silicon Carbide ,
Fused Silica ,applied with advanced ultrafine powder adding technology. by mixing, drying and forming, and fired in a high-temperature shuttle kiln.
* Mullite Cordierite
It has high thermal-sho
ck property, which allows high speed firing and rapid cooling. It offers high purity and porosity, and is capable of dealing with special shapes.
*Alumina
The high heat resistance characteristic makes operations in high temperature zones possible. The high bending strength is also suitable for stacking.
*Silicon Carbide
Great heat-conductivity corresponds to rapid heating/cooling of products. The great bending strength is suitable for high-loading products.
We offers a wide range of compositions designed to meet customer specific needs. All of our silicon carbide refractories are extremely thermal shock resistant.Please contact us for advice on which silicon carbide composition would be best suited for your particular application.
*Fused Silica
While fused silica refractories do not have the high operating temperatures as alumina refractories, it does provide superior thermal shock resistance in both kiln furniture and molten metal applications. In addition to its high thermal shock resistance, fused silica refractories also have an extremely low coefficient of thermal expansion, making it an excellent choice in applications that require dimensional stability.
Feature of sager
*Available in a range of materials and shapes
*Excellent thermal shock resistance
*Shape stability and strength
*Defined flatness and surface finish
*High chemical stability
*High corrosion resistance
Applications
The sagger has the characteristics of compact structure, high compressive strength, good thermal shock resistance, acid and alkali corrosion resistance, anti-flaking, anti-powdering and long service life. The products are widely used in the melting of rare earth magnetic materials, alloy materials and the sintering of ceramic powders.
*Special shapes can be customized as per the requirements of customers.
