Harsh conditions prevail in a rolling mill. Annealing steel is in contact with components of the hot rolling mill, which reduces the service life of these components. Sooner or later, the contacted components have to be replaced because they are too worn. This not only results in costs, but also plant downtime. Some components have to be replaced or serviced much more frequently than others, which reduces the utilization of the entire rolling mill. A more suitable material for the application would provide a remedy. However, trying out possible materials during operation is unthinkable, as the risk of failure of the entire rolling mill is too high. In addition, there are a large number of different variable parameters. This makes a scientifically sound selection of a material almost impossible. The solution is a laboratory test stand that can be used to test the suitability of different materials in a controlled environment. In the course of the feasibility study for the experimental wear testing of components of a hot rolling mill, a special test stand was designed. With this test rig, it should be possible in future to find more suitable materials for individual components of a hot rolling mill. However, the reproducibility and adjustability of real material behavior must be ensured in advance. The design principle of the test stand is relatively simple. A horizontally mounted shaft is driven by an electric motor, at the end of which is the test cell. Testing is carried out using the block-on-disc method. The specified boundary conditions (test temperature = 850°C-1,000°C, test speed = 25m/s) require the sample to be heated. The disc is heated inductively to suit the application. After a series of adjustment tests to determine the parameters, screening tests were carried out to ensure the usability of the test stand. The results obtained are repeatable and provide similar material behavior to that known from the factory. Different materials can be tested with the test setup. It is also possible to vary the test temperature, test force and test duration.
