Low creep high alumina bricks for hot blast stoves

Low creep high alumina bricks are widely used as lining materials for hot blast furnaces, because low creep high alumina bricks have excellent high temperature resistance and creep resistance. As a kind of high-temperature equipment, the internal temperature of the hot blast stove often exceeds 1500 degrees Celsius, so the refractory material needs to have extremely high temperature resistance. Low creep high alumina bricks can withstand thermal stress at high temperatures, are not easy to break, and ensure the stable operation of the furnace.

At the same time, low-creep high-alumina bricks also have excellent creep resistance. Under the action of high temperature and pressure, many materials will creep, resulting in shape deformation and destruction. However, low-creep high-alumina bricks are specially formulated and manufactured to effectively resist thermal and physical creep while maintaining their original size and shape. This characteristic enables the hot blast furnace to operate stably for a long time and prolong the service life of the equipment.

In conclusion, the choice of low-creep high-alumina bricks as the lining material for hot blast furnaces is due to the requirements for high temperature resistance and creep resistance. The material is able to withstand thermal stresses at high temperatures while resisting creep, ensuring stable operation of the furnace and a long life of the equipment.
