<p>It is disclosed a method of casting a directionally solidified (DS) or single crystal (SX) article with a casting furnace comprising a heating chamber (4), a cooling chamber (5), a separating baffle (3) between the heating and the cooling chamber (4, 5). The method comprises the preheating a shell mould (12) within a separate preheating chamber (22), loading the shell mould (12) into the heating chamber (4), where liquid metal (6a) is fed into the shell mould (12), withdrawing the shell mould (12) from the heating chamber (4) through the baffle (3) to the cooling chamber (5) thereby directionally solidifying the liquid metal (15), and finally unloading the mould (12) to a separate cool-down chamber (23). <IMAGE></p> |
