Properties of Products: These Products are made from super andalusite ores, corundum and mullite, being pressed with high pressure and sintered in high temperature. The mullite that formed at the temperature 1350℃ connects the products surface like”welding”, which makes the products in a position of steady, high R-U-L, excellent creeping result and thermal shock resistance. They are special refractory bricks for hot-blast stove of Netherland style.
