    Characteristics

    —High Bulk Densitybetter, high temperature volume stability.

    —Low Water absorptionreduce the water addition for castable and bonding agent for shaped refractory;

    —Low Apparent porosity and impuritiesincrease the slag corrosion resistance at severe working conditions

    —Better grain shapelittle flaky grainincrease the  fluidity of the castable

    — high thermal thock resistance, reducing  the cracks and damage as a result of temperature change.  


         


    Higiant Tabular Alumina TAS apply to the production of purging plug, slide gate plates, tundish function refractory, castable lining for big induction furnace. TAS can improve the thermal shock resistance, slag corrosion resistance and high temperature volume stability,increase service life and reduce consumption.
