Abstract: The invention relates to a device for strip guidance in a hot medium, comprising a deflection roller (3, 38) which has two roller pins (23, 39) and is mounted to supporting arms (1, 2, 34, 37, 54, 57) by means of ceramic journal bearings (20, 31), wherein the journal bearings (20, 31) are in each case arranged in a bearing receptacle (45, 55) of the associated supporting arm (1, 2, 34, 37, 54, 57). The invention is characterized in that at least one of the journal bearings (20, 31) in its associated supporting arm (1, 2, 34, 37, 54, 57) is fixed in the bearing receptacle (45, 55) by means of a force-fit that engages on the outer edge of the journal bearing (20, 31) and balances the different heat expansion coefficients of the journal bearings (20, 31) and the bearing receptacle (45, 55).

Abstract: The invention relates to the field of materials science and to a device for reducing pressure in cavities in media at higher temperatures, such as those devices which can be used for devices for hot-dip coating metal materials in the metal processing industry for example. The aim of the invention is to provide a device by means of which pressure can be reduced in the cavity of the hollow bodies in a reliable and controlled manner and simultaneously the penetration of the media can be delayed or completely prevented at the higher temperatures. This is achieved by a device for reducing pressure in hollow bodies in media at higher temperatures, wherein at least one opening to the cavity of the hollow body is provided in hollow body regions which are not used for the intended application, said opening being closed from the medium surrounding the hollow body by at least one component made of a gas-permeable metal or ceramic material.

Abstract: The invention relates to a device for strip guidance in a hot medium, comprising a deflection roller (3, 38) mounted on supporting arms (1, 2, 34, 37, 54, 57) and a carrier device holding the supporting arms (1, 2, 34, 37, 54, 57). The device is characterized in that one of the supporting arms (1, 2, 34, 37, 54, 57) is mounted on the carrier device by means of a floating bearing (5), wherein the floating bearing (5) allows the mounted supporting arm on the carrier device to move parallel to the longitudinal direction of the deflection roller (3, 38), and in that an elastic counter element (12), which acts parallel to the longitudinal direction of the deflection roller (3, 38) upon the supporting arm (1, 2, 34, 37, 54, 57) mounted on the floating bearing (5), is present and counteracts an increasing distance between the supporting arms (1, 2, 34, 37, 54, 57).
