Automatic line for coated metal mould casting

An automatic line comprises, arranged in series in accordance with the casting flowsheet and interconnected by conveyer means: a unit for applying a coating to the working face of the metal mould parts; a unit for assembling metal moulds from the coated parts thereof; a unit for pouring molten metal into the assembled mould; a unit for solidifying the casting inside the mould; a unit for disassembling the mould and removing the casting therefrom; a unit for cleaning the mould parts off the used coating; a unit for stabilizing the temperature of the cleaned mould parts prior to a re-coating cycle. Arranged along a section of the conveyer means intermediate the mould assembly unit and the pouring unit is a heater with the length thereof being equal to that of the conveyer, and arranged along the section of the conveyer means intermediate the pouring unit and the mould disassembly unit is also a heater with the length thereof being equal to that of the conveyer, which heater becomes operable after the whole automatic line is shut down.
