METHOD OF PRODUCING NON-METAL CASTING

摘要

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 670-950C 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 10-600C 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. ^ 1 ex
