    (57) A continuous casting mould apparatus is provided which includes a liquid reservoir (30) for holding lubricating agent, the agent being applied through channels (29) over the surface of the mould walls (11) by passage from the reservoir (30). The reservoir (30) is adapted to hold a body of lubricant in a lower region thereof with the lubricant covering all of a plura­lity of outlets (29) from the reservoir (30) to the mould walls (11). A gas cushion is provided above the body of lubricant whereby a uniform lubricant flow is discharged through all outlets (29), this gas cushion being generated by feeding lubricant into the reservoir under pressure.
