介绍了CSP除鳞机的原理特性,分析总结了除鳞影响因素,并对邯钢CSP 除鳞机结构组成进行了简要介绍。由于薄板坯连铸连轧的工艺特点,新的轧钢工艺需要有新的除鳞手段。薄板坯和小横截面型材的除鳞要求用水 最少,以避免过冷现象,所以本文针对该除鳞机特性总结了维护方案,并提出了CSP 除鳞机高压集管的维护要点 及性能改进方案,为除鳞机集管的设计、改造、维护提供参考和建议。
针对热轧CSP生产过程中薄规格冷轧基料出现的亮带问题,通过大量的跟踪及测试,找到了亮带的特征和发生规律,并结合CSP 热轧生产过程的工艺特点及试验结果,从理论上分析了亮带产生的原因,并制定了亮带控制的对策,取得了较好的控制效果。

文章简述了电火花毛化的原理及目的, 通过大量的实验数据和前人的经验值分析了毛化程序中通电时间、放电电流、间隙电压等电参数之间的联系以及对轧辊表面质量(表面粗糙度Ra、峰值数Pc、及非对称性粗糙度Rsk)的影响,并初步建立了主要电参数与表面粗糙度之间的数学模型。这样,在从工艺数据库中提取加工参数的方法之外,有了新的方法来获得和优化毛化程序参数,从而有效预测和控制了毛化轧辊的表面形貌,提高了加工的效率

全文介绍了唐钢第二钢轧厂二棒生产线设计生产能力均为60 万吨/年,现都达到100 万吨/年以上。随着产量的增加、设备状态的不断老化,仍沿用最初设计的孔型及导卫系统,造成轧制过程中经常出现质量事故,处理以上事故会浪费大量的轧制时间,造成机时产量低、成材率指标差、车间成本提高。为全面系统地降低事故时间,提高轧机作业率,并进一步提高钢筋产品质量,针对各规格重点架次孔型及导卫系统进行改造。从实际应用效果看
