Blast Furnace 85% Al2o3 High Alumina Brick For Fire Resistant
Product specifications
High alumina refractory is alumina silicate refractory with Al2O3
content above 48%.Generally divided into three categories, first
class: the content of Al2O3 is greater than 75%;Second class: Al2O3
content 60% ~75%;Third grade: Al2O3 content 48% ~ 60%.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.
