Product Description

Clay brick                                                                                                                                                         

Clay brick Al2O3 content is generally more than 40%, Fe2O3 content of less than 2.0 to 2.5%. Ingredients in the clinker for the 65 ~ 85%, combined with 35 ~ 15% clay. The crushed clay and ground clinker are milled and then mixed with the clinker to prepare semi-dry mud, which is sintered at about 1400 ° C and has good performance. Clay brick at high temperature was weak acid, alkali resistance slag erosion ability slightly worse, but with the increase in Al2O3 content and enhanced. Thermal stability than silica bricks, magnesia brick (see magnesia brick), etc. as well.

Qualified blast furnace clay brick after drying treatment of vacuum phosphoric acid impregnation, secondary low temperature firing phosphoric acid impregnated products for masonry blast furnace furnace lining.
