摘　　要：为了精确控制扇形段的辊缝,本文介绍了宝钢4#连铸机扇形段的结构特点及辊缝控制原理,阐述了该扇形段辊缝标定和计算:采用压力控制方式对四个夹紧油缸施加一定的压力,使扇形段上下框架压紧定距块,利用位移传感器检测油缸位置并通过计算转化为辊缝值,使辊缝偏差控制在0.1 mm内;并总结了扇形段标定故障的处理方法,为现场扇形段辊缝维护和操作提供了依据和参考。In order to precisely control the roll gap of the segments, this paper described the structural characteristics of the segments and the principle of gap control of Baosteel 4# caster, and the segments calibration and the calculation of the roll gap. The pressure control method applied to the four clamping cylinders of a certain pressure make the upper and lower frames to be pressed against the distance block, the use of displacement sensors detected cylinder position and into the roll gap through calculation, so that roll gap deviation was controlled within 0.1mm, and the troubleshooting methods of segments calibration were summed up. It provided a basis and reference for the maintenance and the operation of the segments gap.
