FIELD: metallurgy.
SUBSTANCE: invention relates to metallurgy, particularly, to production of casts based on removable (melted, burnt out, gasified) models. Method involves layer by layer deposition on a model of shells by immersing model in a suspension of refractory filler and binder solution and subsequent dusting with granular material. In dusting material of each layer, except last, coacervate is introduced in an amount of 0.5-1.5 wt%. Models are removed and shells are calcined. Coacervate used is alum.
EFFECT: reduced drying time of each layer of shell mold.
