JSP-双机可逆冷轧条件下IF钢织构研究

Study on the Texture of Interstitial Free Steel during JSP-Double Stands Reversible Cold Rolling Process

针对济钢现场工艺条件下生产的Ti-IF钢,利用X’Pert ProxX射线衍射宏观织构分析方法,研究了中薄板坯热连轧轧制及随后的冷轧、退火工艺过程中织构的变化规律。IF钢冷硬板主要织构类型为{111}<110>、{111}<112>和{001}<110>,其中{111}<110>织构强度达到12;再结晶退火后的IF钢退火板,主要织构类型为{111}<110>和{111}<112>,{111}<110>织构强度提高到15.37。济钢生产的Ti-IF钢获得了对板材成形最有利的{111}//ND织构。

Based on the Ti-interstitial free steel produced by Jinan Steel, texture hereditary of Ti-interstitial free steel during JSP-double stands reversible cold rolling processes were studied by means of X’Pert Prox X-ray diffraction. The main texture of the cold rolled IF steel sheet was{111}〈110〉,{111}〈112〉and{001}〈110〉and the density of{111}〈110〉was 12 in which. The main texture of the annealing IF steel sheet was{111}〈110〉and{111}〈112〉and the density of{111}〈110〉was risen to 15.37. The{111}//ND texture which was the best to forming was obtained in the Ti-interstitial free steel produced by Jinan Steel.
