The paper presents results of measuring thermal conductivity of green-sand mould material and time of pure-copper plate castings solidification evaluated from cooling curves. During the experiments pure Cu (99,8 %) plate was cast into the green-sand moulds. Basing on the measurements it was stated that thermal conductivity of the moulding sand has complex temperature variability, especially during the water vaporization and the obtained dependence should be used in the numerical calculations to improve their accuracy.
