Casting equipment for continuous or semi-continuous direct chill casting of meta ls, in particular casting of slugs or billets of aluminium, comprising a cavity (4) wit h an inlet (2) which opens upwards, an intermediate overhang which extends along the mould and is thermally insulated (the hot-top 7) and an outlet with a support (5) whic h can be moved vertically, as well as means (10) for supplying water for chilling the molten metal. The wall of the cavity is comprised wholly or partially of a permeable ma terial and the oil and/or gas are/is designed to be supplied through the permeable mate rial so as to form an oil and/or gas layer between the metal and the mould wall, whic h prevents the metal from coming into direct contact with the mould wall. At least the part of the cavity wall (12) where the oil is supplied to the cavity is made of the same fireproof material as the hot-top (7) and constitutes an integrated part of the hot-top.
