METHOD OF PRODUCING NON-METAL CASTING Russian patent published in 2012 - IPC C04B35/653 C04B41/87 

FIELD: process engineering.

SUBSTANCE: proposed method relates to production of non-metal components for construction structures, heat engineering assemblies and chemical hardware with aggressive working media. Non-metal materials are fused and melt is poured into mould. Produced cast is cooled by sprinkling with water to 670-950°C for solid particles of aluminium to be charged on cast surface. Aluminium on cast surface is fused by cast heat to create 1-9 mm-thick aluminium melt layer on cast surface. Then, said melt is blown by air at melt temperature of 10-600°C unless complete oxidation of aluminium and production of component. Air temperature is decreased at aluminium layer smaller thickness and increased at larger thickness.

EFFECT: higher homogeneity, chemical and heat resistance.
