Wear and friction are always crucial factors in machines and systems, which can have a major impact on their service life, running costs and efficiency. Every machine has at least one moving component, i.e. a so-called tribological contact, which causes friction and wear. Nowadays, the requirements placed on machines are becoming ever greater. Conserving resources and costs, minimizing downtime and increasing environmental friendliness are just a few examples. Optimizing a tribological contact in the machine can have a major impact on these points. However, the degree of wear often depends on the material pairing and other parameters such as the load, temperature and relative speed. As wear is therefore a system variable and not a material property, it is almost impossible to make a statement about the wear that may occur without carrying out tests. One such highly stressed tribological contact is found in a hot-wire rolling mill. Relative speeds of over 110 m/s at temperatures of up to 1000 °C are achieved in this system by the rolled hot wire. As the wire can often reach a length of up to 6 km, it has to be wound into so-called “coils” at the end of the rolling mill. This is achieved with the help of a laying tube. The wire shoots through the bent tube and ends up in circular loops. Lubrication is not possible due to the high temperatures of the wire. The laying tube wears out during this process and must be replaced after a certain period of time. This master's thesis was carried out in order to optimize the process, minimize downtime and increase resource conservation. The aim was to determine the wear behavior of the laying tube depending on the temperature and the oxygen in the ambient medium. Therefore, an existing testing machine was modified, automated and optimized, and a new force application system was designed using a pneumatic muscle. A disk with a diameter of 200 mm is mounted on this horizontal tribometer as a wire sample. The disk is inductively heated up to 950 °C and rotated to 4,500 rpm using a servomotor. The alloy tube sample is pressed against this heated disk for approx. 30 minutes by applying force. The resulting wear is determined using a tactile surface measuring device and a digital microscope. The wear volume [mm3] and the geometry of the wear track are evaluated from a total of 12 tests. The tests were carried out at 800 °C, 850 °C, 900 °C and 950 °C with a normal force of 19 N in each case. The result shows that only the temperature has an influence on the wear of the alloy tube sample. Oxygen does not significantly influence wear in this tribological system up to a residual content of 2.4 % in the ambient medium at a temperature of 850 °C. Almost half of the wear can be avoided by increasing the wire sample temperature from 800 °C to 950 °C. However, greater wear with increasing temperature was clearly visible on the wire sample.
