Corundum refractory bricks are refractory products with alumina
content greater than *0% and corundum as the main crystal phase.
High normal temperature compressive strength (up to **0MPa). High
load softening start temperature (greater than ***0 ° C). Very good
chemical stability, strong resistance to acidic or alkaline slag,
metals and glass liquids. Thermal shock stability is related to its
organizational structure. Corundum bricks can be divided into
sintered corundum brick and fused corundum brick. Sintered alumina
and fused corundum can be used as raw materials, or alumina clinker
with high Al2O3 / SiO2 ratio can be combined with sintered alumina
and made by sintering. It can also be made of non-burning corundum
brick with phosphoric acid or other binders. Mainly used in
iron-making blast furnace and blast furnace hot air furnace,
steel-making furnace refining furnace, sliding water heater, glass
melting furnace and petrochemical industry furnace.
As a professinal corundum refractory materials manufacturer, we
have exported different corundum refractory bricks to more than *0
countires.Please kindly read the following and make
