Abstract: A tube exchange device for holding and replacing refractory nozzle comprises a frame with a casting opening. The frame is configured to be fixed to the lower side of a metal casting vessel. The frame is has an upper portion and a lower portion joining at a middle section plane in which an inner nozzle and an exchangeable pouring nozzle form a sliding contact. The lower portion of the frame contains a displacing element and a guiding element disposed for displacing and guiding the nozzle from a standby position to a casting position, and a pressing element pressing the nozzle at the casting position towards the upper portion of the frame. In a combination of the tube exchange device and a nozzle, the nozzle comprises bearing elements mating with the clamping elements of the tube exchange device.
