矫直机是轧钢机上的配套设备,矫直机上的矫正圈主要用于各种型钢,角钢及园钢轧制后进行矫直的主要备件。它不但要承受矫直时的压力,而且还要承受一定的冲击力,因此,对于矫正圈来说,要有较高的表面硬度,和一定的韧性。我厂生产的太钢一轧厂所用的800矫直机矫正卷(见图一),材料为60siMnA,其化学成分:C:0.58, Straightening machine is an auxiliary equipment on the rolling mill. The straightening ring on the straightening machine is mainly used for the main spare parts for straightening of various shaped steel, angle steel and circular steel rolling. It not only to withstand the pressure straightening, but also bear some impact, therefore, for the correction of the ring, have a higher surface hardness, and a certain degree of toughness. I plant a TISCO rolling mill used 800 straightening machine straightening coil (see Figure I), the material is 60siMnA, its chemical composition: C: 0.58,
