FIELD: process engineering.
SUBSTANCE: proposed process comprises preparation of aqueous slip containing refractory fibres, production of fibrous blank by vacuum forming of aqueous slip and forming of green blank at pressure by rolling followed by drying. Aqueous slip is prepared by aeration homogenization at gas pressure of 0.8-4.0 atm.
EFFECT: higher flexibility, lower density of fibrous heat insulator.
