Abstract
A strand guide for a continuous casting plant includes rollers supporting and guiding the strand. Each roller has a cavity through which a coolant flows and which is connected with a coolant supply duct and a coolant discharge duct. The coolant discharge duct is aligned in duct-like manner with at least one tuyere or a set of tuyeres of an external cooling device. In order to combine the advantages of an external cooling device with the advantages of an internal cooling of the rollers, the external cooling device includes tuyeres or sets of tuyeres arranged between the rollers. Each tuyere or set of tuyeres is arranged adjacent the roller end that includes the coolant discharge duct. The jet direction of the tuyere or tuyeres of the set of tuyeres is directed opposite to the flow direction of the coolant through the roller.
