Dense Density High Temp Fire Brick , Cement Kiln Refractory Bricks Alkali Resistant
Introduction:
High strength alkali resistance brick is made by adding additives to improve the compression strength on the basis of the ordinary. The product has high strength, good volume stability, alkali erosion ability, etc. It is applicable to the cement kiln preheater and decomposing furnace, air duct, etc.
Feature:
Dry pressed
Burned under tunnel kiln
Accurate dimension
High strength
Application:
High strength alkali resistance brick is widely used in steel furnaces, iron making furnaces, glass kiln, ceramic tunnel kiln, cement kiln.
