小规格棒材的生产率一般较低。为提高经济效益,曾采用过两线轧制、切分轧制和提高轧制速度等措施。由于坯料切分轧制的断面减缩率小于两线轧制,因而要求的机架数较少,在不提高轧制速度的情况下,切分轧制能获得较高的生产率。 The productivity of small gauge bars is generally low. In order to improve economic efficiency, we have adopted two-wire rolling, cutting and rolling and improve the rolling speed and other measures. Since the reduction of the cross-sectional reduction of the billet cutting and rolling is smaller than that of the two-wire rolling, the number of racks required is small, and the high productivity can be obtained by the dicing and rolling without increasing the rolling speed.
