METHOD OF PRODUCTION OF FOUNDRY CERAMIC MOULDS ON INVESTMENT PATTERNS Russian patent published in 2014 - IPC B22C9/04 

Abstract RU 2536130 C2

FIELD: metallurgy industry.

SUBSTANCE: prepared fire-resistant suspension is applied in layers on a model by the method of immersion and the cushion layer is applied. To form on the model of the second and subsequent layers after immersion of the model in the suspension the exposure is carried out for 5 seconds, and the exposure of the mould-casing with the model in the suspension to form the fifth and subsequent layers, besides the securing one, is carried out for 2 seconds. The fire-resistant layers are dried and cured. The model is removed, the mould-casing is dried and calcinated.

EFFECT: increased efficiency of the manufacturing process of the ceramic moulds, and obtaining stable values of strength of ceramics.
