METHOD FOR MANUFACTURING OF CERAMIC MOLDS ACCORDING TO MELTED MODELS FOR OBTAINING PRECISE CASTINGS FROM CHEMICALLY ACTIVE AND HEAT-RESISTANT ALLOYS Russian patent published in 2021 - IPC B22C9/04 B22C9/12

Abstract RU 2757519 C1

FIELD: foundry production.

SUBSTANCE: method for manufacturing of ceramic molds based on melted models for casting chemically active alloys includes layer-by-layer application of a ceramic suspension based on alumosol and corundum filler with sintering additives and sprinkling with corundum granular material on the model block. After applying each layer, the model ceramic block is exposed to vacuum treatment to a residual pressure of 0.506⋅10⁴-5.065⋅10⁴ Pa for 10-20 minutes.

EFFECT: acceleration of ceramic shell form formation on model block is provided.
