介绍了半无头轧制飞剪的工作状态分析与控制、半无头轧制与辊缝润滑的联合应用等关键设备与技术分析,以及半无头轧制对薄规格及超薄规格产品组织性能和板带出口厚度偏差、板凸度及楔形度等板形质量的影响。结果表明:半无头轧制超长带钢的组织性能具有高的均匀性和稳定性,在保证超长带钢板厚精度和板形质量以及扩大薄带钢规格范围方面,半无头轧制比常规短坯轧制具有明显的优势。同时指出,半无头轧制薄规格产品在“以热代冷”方面应用广泛。 Introduced the semi-endless rolling flying shear working condition analysis and control, semi-endless rolling and joint lubrication of the joint application of key equipment and technical analysis, as well as semi-endless rolling of thin and ultra-thin specifications of the product organization Performance and plate thickness deviation outlet, plate crown and wedge shape of the impact of plate quality. The results show that the microstructure and properties of the semi-endless rolled ultra-long strip have high homogeneity and stability. Semi-endless rolling is the key factor to ensure the strip thickness and shape quality, Than conventional short billet rolling has obvious advantages. At the same time, pointed out that the semi-endless rolling of thin specifications in the “to heat on behalf of cold ” is widely used.
