Abstract:
The invention concerns the use of a reactive refractory mortar which is self-extinguishing beyond a predetermined penetration depth. The mortar consists of a mixture of 11 to 17 dry wt % aluminium powder, 18 to 31 dry wt % iron oxide, 8 to 18 dry wt % magnesium sulphate dissolved in water and 44 to 60 dry wt % magnesium oxide. The mortar is used for pointing refractory kiln linings consisting of refractory bricks, in particular for rotary kilns.
Abstract:
The invention concerns a lining for furnaces, mills or containers, said lining comprising at least one cover layer and at least one carrier layer which are interconnected such that they adhere firmly by ceramic bonding as the result of the burning down of a reactive exothermic mortar. The invention further concerns a method of producing a lining for furnaces, mills and containers by arranging layers of this type.
