High alumina wear resistant castable
High strength high alumina wear-resistant castable refractory is made of high grade bauxite and mullite, and nanoscale material formulated in proportion scientifically.
High strength high alumina wear-resistant castable refractory produced by our company has excellent wear resistant performance, the wear resistant coefficient is better than the ordinary market high alumina wear resistant castable more than 1 times, and has good thermal shock stability which is suitable for wear resistance of different high temp kilns.
High strength high alumina wear-resistant castable features:
1.With good molecular structure strength, the wear resistant coefficient is 1 times higher than the industry standard.
2.With good construction performance, can be applied to the construction needs of different temp sections.
3.With good slag resistant performance, strong erosion resistance, can be used in harsh operating environment and not easy be damaged.
4.With low high temp creep rate, small thermal expansion, and good rapid cooling and thermal resistance.
