1、Tabular Alumina
Product introduction：
The product appears in white color and is available in various grain sizes and ground mesh powers. These products in which the Tabular Alumina is used have an excellent performance in their high grade refractory applications. Therefore it is suitable for applications in refractories and abrasives. It is used in many industries such as high-temperature engineering equipment, metallurgical and chemical fields , ceramics and construction materials.
Benefits：
High refractoriness
Excellent thermodynamic properties
High volume stability
High density, low permeability
High thermal shock resistance
High chemical resistance
High purity
High mechanical stability
High wear-resistance
Applications：
Tabular Alumina is the material of choice in unshaped and shaped high performance refractories used in a variety of industries (steel, foundry, cement, glass, petrochemical, ceramic and waste incineration). Other common non-refractory applications include its use in kiln furniture and for metal filtration.

2、Functional Refractory for Steel Continuous Casting
Purging Plugs
Well Block and Mortar for Plugging Plugs
Zirconic Metering Nozzles
Ladle Shroud，Submerged Entry Nozzle and Monolithic Stopper
Functional Refractory for Steel Continuous Casting has muti-functions, excellent properties and extended service life. Al2O3-C shroud (ZrO2-C compound for slag line), submerged entry nozzle and monolithic stopper have high strength, good corrosion resistance and thermal shock resistance. Shroud can be used directly without per-heating due to its excellent thermal shock resistance; submerged entry nozzle has reasonable materials composition and structural configuration design made it can ensures to from even and stable steel stream in con-casting.
