薄规格酸洗板热连轧关键生产工艺控制

Control of Critical Hot-rolling Process for Pickled Sheet Steel

针对热轧酸洗板表面质量要求高、薄规格酸洗板生产时单位轧制力大、易出氧化铁皮缺陷、并易发生甩尾现象、生产难度大的特点,从热轧生产工艺入手,对薄规格酸洗板的钢种特点进行分类控制,同时对薄规格的热轧关键生产工艺进行了分析,并开发了关键控制工艺点,包括温度控制、轧辊使用、轧制计划编排,以及尾部轧制稳定性控制中的自动调平、轧辊受损预防控制等技术。

In view of high surface quality requirement and difficult production for large specific rolling pressure, prone to scale and tailing out of pickled sheet steel, the key technologies were analyzed, and the sheets were classfied control by steel grade. Therefore, some key technologies about temperature control, roll usage, rolling scheme, tail rolling stability control, etc. , were developed.
