穿孔机最优导盘转速确定

Determination of Optimal Revs of Piercer's Guide Disc

穿孔机是无缝钢管生产中的一个重要设备,针对长期以来对其工艺参数进行调整都必须先停止生产,从而大大降低了生产效率的问题,宝钢通过对SWW斜轧穿孔机狄塞尔导盘的改造,实现了穿孔机一个重要工艺参数导盘转速的在线调整.介绍了狄塞尔导盘改造方法,并针对生产现场关心的最优导盘转速问题,在ICA(independent component analysis)算法的基础上,引入回归方法提出了ICR(independent componentregress)算法,建立了穿孔机最优导盘转速模型.实验验证,该模型得到的最优导盘转速可有效提高产品质量和生产效率,降低能耗.

Piercer is an integral equipment to seamless steel tube rolling, to which the problem that a pause is necessary when readjusting rolling parameter is unsolvable for long, thus reducing the productivity greatly. Nowadays the BaoSteel has implemented the on-line readjustment of an important rolling parameter, i.e. , the guide disc revs, by rebuilding the Diescher guide disc on SWW skew rolling piercer. Describes the way to rebuild the Diescher guide disc and, based on ICA, the ICR is introduced in solving the optimal revs of the disc. A model is developed for the optimal revs of the disc. Test results show that the optimal revs given by the model can improve both product quality and productivity effectively with energy saving realized.
