General Information of Fireclay brick UNF42
Our corporation produces a comprehensive range of Fireclay bricks, with 30% to 55% alumina content, all of these bricks exhibit excellent performance.
Our Fireclay bricks are the final result of blending excellent fused alumina and silicon as the main raw materials with cutting-edge technology, adding superfine powder, after mixing, drying, forming, in the high temperature shuttle kiln. We ensure you that the Fireclay Bricks made by us possess high quality standard and have gone through all the complicated quality control parameters. Their durability and strength adds life to the structure and they have the capacity of bearing high temperature.

Feature of Fireclay Brick UNF42
Resistant to thermal shock, abrasion, chemical attack
High ability for anti-abrasion during work
Low shrinkage degree under high temperature so as to maintaining integrity of the furnace lining
Low apparent porosity, and low Fe2O3 content to reduce the carbon deposit in the blowhole and avoid the bricks broken in case of expansion.
