1.Low thermal conductivity,
2.Good thermal insulation performance.
3.Good integrity with furnace lining

Tyical Features:

High compressive strength in normal temperature, high ability for anti-abrasion during work, low shrinkage degree under high temperature so as to maintaining an integrity of the furnace lining; low apparent porosity, and fe2o3 content to reduce the carbon deposit in the blowhole and avoid the bricks broken in case of expansion; seldom melting point settings shape.

Fireclay bricks are divided into different kinds which are mainly as below:
(1) Normal Purpose Fireclay Bricks
(2) FireClay bricks for coke oven
(3) FireClay bricks for blast furnace
(4) FireClay bricks for Hot-blast Stove
(5) Glass furnace Bottom Fireclay Blocks
(6) Lower porosity Fireclay bricks
Application:
Fireclay bricks are widely used in coke oven, balst furnace, hot-blast stove, reheating furnaces, ladle furnace, glass furnaces, refining furnces ,carbon baking furnace etc.
