METHOD TO MANUFACTURE LIGHT-WEIGHT HEAT INSULATION ITEMS FOR LINING OF THERMAL AGGREGATES

摘要

FIELD: construction.SUBSTANCE: method may be used to manufacture light-weight silica-alumina items of normal dimensions and simple cuts, designed for lining of thermal aggregates in zones with temperature of up to 1250°C, not exposed to action of melts, wear forces and mechanical shocks. The method includes preparation of a charge from chamotte, a binder and additives, shaping, drying and baking of items.EFFECT: higher strength of light-weight heat insulation items for lining of thermal aggregates with preservation of low density and heat conductivity.1 ex, 4 tbl
