半无头轧制薄规格带钢的组织性能与板形

 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。

Microstructure-Properties and Profile of Thin Strip by Semi-Endless Rolling

The key equipment and technology analysis of semi-endless rolling,such as the flying shear working status analysis and control,the joint application of semi-endless rolling and rolls gap lubrication,were introduced,and the effect of semi-endless rolling process on the microstructure and properties,thickness accuracy and profile quality(such as strip crown and wedge degree) was discussed.The results show that the microstructure and properties of the ultra-long strip produced by semi-endless rolling process have better uniformity and stability.Besides,semi-endless rolling process has obvious advantage in terms of ensuring good thickness accuracy,perfect profile quality and expanding specifications of the thin strip products compared with conventional short-slab rolling.Furthermore,the semi-endless rolling process for ultra-thin strip has been applied widely in the replacement of cold product by hot product.
