Mold for the continuous casting of metal and a process for producing such a mold

A mold (10) for continuous casting of metal, the mold comprising a coolable running surface (11) and a guide (12) for molten metal, the guide comprising a refractory material, wherein the guide (12) is disposed upstream of the running surface (11) in a direction of flow, wherein the guide (12) is radially prestressed and comprises a nozzle plate (12a) disposed substantially perpendicular to the direction of flow and a projection (12d) provided at an outer end of the nozzle plate (12a) and extending toward the direction of flow, wherein the guide (12) is press-fitted to a holding element (13) which comprises a fastener (13a) and a clamp (13b), wherein an outer circumferential surface (14) of the guide (12) and an inner circumferential surface (15) of the holding element (13) are each conical in design and the fastener (13a) and the clamp (13b) are prestressed in the mold's axial direction, wherein the prestress between the clamp (13b) and the fastener (13a) acting in the axial direction of the mold (10) has a radial component in a region of the guide (12), such that the guide (12) is loaded with a radial prestress.
