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.
