Product Description

High Alumina Refractory Brick for Blast Furnace
The Description:
High alumina refracotry brick for hot blast stove refers to the refractory products made of high bauxite clinker or sillimanite mineral with an Al2O3 content of not less than 48%, which is used for masonry hot blast stove. Hot blast furnace is a huge brick structure built entirely of refractory materials, which provides blast furnace hot air for blast furnace smelting equipment. The internal masonry is subjected to high temperature and its own load for many years, and is eroded by various oxide dust in the gas.
