Characteristics of low creep clay firebrick:
1, Low creep rate, high temperature creep becomes smaller.
2. High softening temperature under load.
3, Good impact resistance.
4, High temperature compressive strength.
5, High temperature volume stability, good wear resistance.
6, Good erosion resistance.
Low creep clay refractory brick application:
It can be used in the hot blast furnaces supporting large and medium blast furnaces, mainly used in the low temperature parts of hot blast furnaces such as the middle and lower wall of the regenerator chamber and the lower lattice brick. It can also be used in blast furnace, cupola, heating furnace and coke oven and other thermal equipment.
Company profile and main products:
Our total annual production capacity is about 100,000 tons of dense-shaped refractory product, and 100,000 tons of monolithic refractory product.
We have three tunnel kilns for silicon-aluminum dense bricks and one new plant for the monolithic refractory.
We're sure our custom-made products and professional services will bring you a stable quality supply and more profit.
