Product Description

Low-Creep  Heavy Weight High Alumina  Refractoy Brick for Hot Blast Furnace
The description:
Low creep high aluminum brick is a kind of high aluminum refractory brick, because of its low creep rate, it is also called low creep high aluminum brick, which is used in high temperature industrial kiln under long-term high temperature environment. Compared with ordinary high alumina bricks, high quality bauxite is used, with blue stone, andalusite, sillimanite these high-end "three stone" refractory raw materials fired, three stone components can complete two mullite crystallization in the firing process, and finally form a stable mullite phase, so that it has very good creep resistance. Products according to physical and chemical indicators can be divided into DRL-155, DRL-150, DRL-145, DRL-140, DRL-135, DRL-130 six brands.

Product category:

According to different furnace type design, hole brick has 7 holes, 19 holes, 37 holes, wall brick according to the furnace type design and production, pipe and hot air outlet brick, support customization.

Product features:

1, Low creep rate, high temperature volume stability. Under the action of constant temperature and constant load, the high aluminum brick changes with time, its internal has small changes, the volume is stable in high temperature environment, and it is not easy to occur such as furnace lining falling off.

2, Gas erosion resistance, good erosion resistance. In high temperature environment, low creep high aluminum brick not only volume is not easy to change, good resistance to gas erosion, long service life.
