Gray Corundum 98% Shaped Refractories Vice White Fused Alumina 1-3MM 3-5MM For Refractory Brick

Gray Corundum 98% Shaped Refractories Vice White Fused Alumina 1-3MM 3-5MM For Refractory Brick

 

Description:

 

RS Brown fused alumina 98% is made by a special technique in electric arc furnaces with high temperature above 2300°C and refining with longer time. RS Brown fused alumina 98% is the ideal product which can substitute white fused alumina, compact fused alumina and tabular alumina in China .

 

RS Brown fused alumina 98% sand (Barmac production line) and powder (acid washing) produced by Rui Shi plant is characterized by without bursting, without pulverising and high bulk density, good flow property etc,
