abstract the present invention relates to a cooled strand guide roller (1) mounted at more than one location for guiding a metal strand (s) in a continuous casting machine, and to a method for cooling a strand guide roller (1) mounted at more than one location. the problem addressed by the invention is to specify an internally cooled strand guide roller (1) mounted at more than one location, said strand guide roller (1) being configured in a simple, robust and operationally reliable manner. furthermore, the height of the strand guide roller (1) is intended to be adjustable easily and quickly. the solution is achieved by way of a strand guide roller (1) having a collecting bar (7) for supplying the strand guide roller (1) with cooling water, said collecting bar (7) comprising a plurality of brackets (10, 10a, 10b) and, in each case between two successive brackets (10, 10a, 10b), at least one coolant pipe (11) for fluidically connecting the brackets (10, 10a, 10b), wherein an outer bracket (10a) has in each case at least one first connection (8) for internal cooling of the cooled strand guide roller (1) and at least one second connection (9) for cooling the bearing blocks (4), and the first connection (8) is fluidically connected to the ducts (3) of the individual rollers (2a, 2b) and the second connection (9) is fluidically connected to the bearing blocks (4) via the brackets (10). tradução do resumo resumo patente de invenção: "rolete-guia de filamento resfriado montado em mais de um local" a presente invenção se refere a um rolete-guia de filamento resfriado (1) montado em mais de um local para guiar um filamento de metal (s) em uma máquina de fundição contínua, e a um método para resfriar um rolete-guia de filamento (1) montado em mais de um local. o problema abordado pela invenção é especificar um rolete-guia de filamento internamente resfriado (1) montado em mais de um local, em que o dito rolete-guia de filamento (1) é configurado de maneira simples, robusta e operacionalmente confiável. ademais, a altura do rolete-guia de filamento (1) se destina a ser ajustável de maneira fácil e rápida. a solução é alcançada por meio de um rolete-guia de filamento (1) que tem uma barra coletora (7) para abastecer ao rolete-guia de filamento (1) água de resfriamento, em que a barra coletora (7) compreende uma pluralidade de suportes (10, 10a, 10b) e, em cada caso, entre dois suportes sucessivos (10, 10a, 10b), pelo menos um cano de líquido refrigerante (11) para conectar de maneira fluida os suportes (10, 10a, 10b), em que um suporte externo (10a) tem, em cada caso, pelo menos uma primeira conexão (8) para resfriamento interno do rolete-guia de filamento resfriado (1) e pelo menos uma segunda conexão (9) para resfriar os blocos de rolamento (4), e a primeira conexão (8) é conectada de maneira fluida aos dutos (3) dos roletes individuais (2a, 2b) e a segunda conexão (9) é conectada de maneira fluida aos blocos de rolamento (4) através dos suportes (10). A cooled strand guide roller (1) mounted at more than one location for guiding a metal strand (S) in a continuous casting machine, and a method for cooling a strand guide roller (1) mounted at more than one location. An internally cooled strand guide roller (1) is mounted at more than one location. The height of the strand guide roller (1) is intended to be adjustable easily and quickly. The strand guide roller (1) has a collecting bar (7) for supplying the strand guide roller (1) with cooling water. The collecting bar (7) includes a plurality of brackets (10, 10a, 10b). Between two successive brackets (10, 10a, 10b), there is at least one coolant pipe (11) for fluidically connecting the brackets (10, 10a, 10b). An outer bracket (10a) has at least one first connection (8) for internal cooling of the cooled strand guide roller (1) and at least one second connection (9) for cooling the bearing blocks (4). The first connection (8) is fluidically connected to the ducts (3) of the individual rollers (2a, 2b) and the second connection (9) is fluidically connected to the bearing blocks (4) via the brackets (10).
