Abstract Scope |
Non-grain-oriented (NO) electrical steel is widely used in electrical machines with rotating magnetic fields. The process chain consists of hot-rolling with optional batch-annealing followed by cold-rolling and final continuous annealing. Each step has a significant influence on microstructure and electromagnetic properties. A tailor-made microstructure, with specific grain-size and texture, can greatly improve magnetic properties of NO sheet material and thus the performance of rotor/stator components. For the design of such an ideal microstructure, it is necessary to quantify the influence of process-parameters on the microstructure. In the current work, texture evolutions during cold-rolling and due to recrystallization during final annealing will be evaluated based on EBSD-measurements for different conditions. Modelling approaches describing the formation of deformation and annealing texture are presented and discussed in combination with the experimental results. The through-process texture analysis provides new insights into the optimum microstructure of NO steels, leading to an improvement of electromagnetic properties. |
