摘要
In rolled strip material,the orientation of the crystallites,known as texture,is influenced by various kinds of thermo-mechanical processes,such as casting,plastic deformation,annealing and phase transformation. The modern industry production requires stable product performance,real-time monitoring and full controlling of the quality.The online texture measurement in metal rolling can be used to real-time monitor the whole process, and then feedback control to the production process can be implied to adjust the process parameters to ensure the stability of the products.The principles,advantages and disadvantages of related detection methods(2D X-ray diffraction,neutron diffraction,laser-ultrasonics and electromagnetic acoustic transducers(EMAT)) and the possibility of online measurement are discussed.Finally,2D X-ray diffraction and laser-ultrasonics are employed on online texture measurement,and the schemes of online texture measurement are proposed.

The principles, advantages and disadvantages of related detection methods （2D X- ray diffraction, neutron diffraction, laser-ultrasonics and electromagnetic acoustic transducers （EMAT）） and the possibility of online measurement are discussed. Finally, 2D X-ray diffraction and laser-ultrasonics are employed on online texture measurement, and the schemes of online texture measurement are proposed.
