FIREPROOF MATERIAL FOR MOUNTING AND REPAIR OF BRICK-LINING OF THERMAL UNITS Russian patent published in 2013 - IPC C04B35/66 C04B35/42 

FIELD: chemistry.

SUBSTANCE: fireproof material for mounting and brick-lining of thermal units can be applied as fireproof unmolded material for mounting and repair of brick-lining of steel-melting converters, electroarc, open-hearth furnace, and heating and quenching furnaces, scoops, for mounting and repair of brick-lining of copper-melting and zinc converters, reverberatory and bath furnaces, rotary Waelz kilns, as well as for mounting and repair of rotary furnaces for burning concrete clinker, and for brick-lining of rotary and tunnel furnaces. Material has the following composition wt %: fireproof filler 39.0-84.0; fireproof clay 0.5-7.0; natural alkaline alumosilicate 0.01-5.0; hydraulically active aluminate 0.05-1.0; organic thixotropic component 0.1-1.0; organic structure-forming component 0.1-1.0; inorganic structure-forming component 0.1-1.0; dry soluble binding agent 0.1-10.0; aluminium powder 2.0-15.0; mixture of bi-and trivalent iron oxides 10.0- 35.0.

EFFECT: technical result, which is reached by claimed invention, consists in increased durability of solution cohesion with brick-lining, reduction of porosity, increase of cold strength and terms of mass setting, as well as increase of agglomeration rate.
