薄板坯连铸连轧生产冷轧用低碳热轧带钢的力学性能 总被引:3,自引:1,他引:3
综述了板坯连铸连轧生产冷轧用低碳热轧带钢力学性能偏高的现状以及性能强化机理.讨论了性能软化的途径.指出通过提高钢的纯净度、降低夹杂物含量、采用铁素体温度范围轧制、高温卷取(≥700 ℃)工艺以及硼微合金化等措施,可以得到屈服强度不超过255 MPa的冷轧用低碳热轧带钢,并生产出合格的冷轧深冲板. 相似文献

The hot rolled strip of Fe-3Si steel was experimentally produced by thin slab casting and rolling (TSCR) process in the laboratory. The texture evolution rule was investigated during hot rolling and cold rolling. The texture distribution of cold rolled strips with four kinds of cold rolling reduction schedules was observed through X-ray diffraction method, and the orientation density variation of 1/16 layer, 1/8 layer, 1/4 layer, and 1/2 layer in thickness was analyzed. The cold rolled texture of steel A with four kinds of cold rolling reduction schedules was mainly composed of α and γ fibers. Cold rolling reduction ratio of 70% was more beneficial for obtaining more γ fibers. The γ fiber texture orientation density of {111}<011> and {111}<1 12> was the largest on the 1/8 layer and 1/4 layer and the least on the 1/16 layer and 1/2 layer for steel B. The texture orientation density of {001}-{223}<110> in the α fibers for steel C was increased, but the texture orientation density of {332}-{110}<110> was low. 相似文献
