Anti Corrosion High Alumina Refractory Brick For Furnace Lining
Good price high alumina refractory brick for furnace lining
Product specifications
High alumina refractory is alumina silicate refractory with Al2O3 content above 48%.Generally divided into three categories.It can also be classified according to its mineral composition.The proportion of each mineral phase depends on the type and quantity of Al2O3/SiO2 and the impurity contained in the product, and also on the production process conditions.
We bring forth high quality High Alumina Bricks, which is manufactured to meet the requirements of neutral refractoriness where safe working temperature is more than 1300 degree centigrade. We offer high Alumina Bricks in different specifications as per customer requirements.
