Abstract

The quick detection method for punched steel plate polar diagram data belongs to the field of X-ray detection technology. From eight polar diagrams of different crystal plane indexes {110}, {200}, {211}, {220}, {310}, {222}, {321} and {400}, 2-6 is selected as the tested polar diagrams. In 2D X-ray detection system, the polar diagram data in some alpha angle and some beta angle ranges. There data are utilized to ensure the consistency of the polar diagram method and traditional measurement method. The present invention has detection period only one percent of that in traditional detection method and has raised in-situ measurement precision. The present invention is suitable for industrial application.

Description

Technical field:

[0001] The invention belongs to the technical field of X-ray detection. Background technique:

[0002] Stamped steel plate is an important high-tech steel product for iron and steel metallurgical enterprises today. The texture of this type of steel plate and its corresponding plastic deformation anisotropy make it have excellent deep drawing deformation ability, and it has been widely used mainly in the automobile industry. The traditional detection of texture and corresponding plastic strain ratio is usually carried out offline. The shortcomings of this detection method are destructive, non-instantaneous, non-continuous, etc., and cannot meet the needs of large-scale modern steel production.

[0003] The development and mass production of ultra-deep-drawn interstitial-free steel sheets and ordinary stamped steel sheets make it urgent for modern metallurgical production enterprises and the automobile industry to establish an online non-destructive testing ...
