Low Creep Low Apparent Fireclay Refractory Brick for Nonferrous Metal Smelting
The Description:
On the basis of the production of general clay bricks, using homogenizing material as the main raw material, adding an appropriate amount of auxiliary materials and some additives, after fine grinding, mixing, high pressure molding, in the appropriate firing temperature into mullite crystal phase, the use of residual products with good mineral composition, Thus, the product has high refractoriness, compact volume density, low porosity, excellent high temperature creep performance and good volume stability.
Carbon roaster refractories, including general clay bricks and low creep clay bricks. In recent years, in order to reduce the collapse of the furnace wall in the process of use, the carbon furnace brick has a transition trend from general clay brick to low creep clay brick.

Product feature:
Low creep fireclay brick has the advantages of high heat storage capacity, low creep rate, good thermal shock resistance and corrosion resistance to acid slag. Especially in the middle and upper part of the reheater chamber, this area bears the load of the upper lattice brick. If the high aluminum brick of ordinary material is used, the periodic temperature fluctuation will lead to the cracking and crushing of the lattice brick, and in serious cases, the lattice brick will collapse. The replacement of low creep clay lattice brick can avoid such problems and reduce the material selection cost of the project.
