This paper describes application situation of rotary coder on bucket stack-reclaimer, the practice shows the application of high speed counter function of programmable controller together with application of rotary coder can effectively realize rotary angle measurement and rotary protection function to equipment, which is capable of realizing the purpose of accurate positioning, easy adjustment, safety and reliability.

介绍了旋转编码器在斗轮堆取料机的应用情况，实践证明，利用可编程序控制器的高速计数器功能配合旋转编码器的使用，可有效地实现对回转角度的测量和对设备的回转保护功能，能够达到定位准确、调整方便、安全可靠的目的。

Roll wear is a factor difficult to determine and there is no suitable theoretical model till now In this paper,the theoretical model of roll wear is established from the view of tribology,and the roll wear on finishing train of 2050 CVC hot strip mill has been measured The calculated results agree well with the measured,so the model for roll wear is of important significance for shape control

轧辊磨损是当前生产中难以定量确定的因素，磨损预报至今尚无精确的理论模型可利用。本文从摩擦学原理出发建立了轧辊磨损的理论模型，并对宝钢 2 0 5 0 CVC热连轧机精轧机组的轧辊磨损量进行实际测量，计算结果与实测值吻合较好，对提高磨损预报精度、提高板形控制技术水平具有重要意义

In implementation, a feeler gauge measures the thickness of the just-made sheet metal and sends this signal back to a servo-motor controlling the single variable of traction, the variable to affect the steel last, just before the rollers.

在实施过程中，由一个厚薄规测量刚刚制成的金属板的厚度，然后把信号传回一个伺服电动机以控制牵引力的单一变量——在卷板机之前最后影响钢板的变量。

In implementation, a feeler gauge measures the thickness of the just-made sheet metal and sends this signal back to a servo-motor controlling the single variable of traction, the variable to affect the steel last, just before the rollers.

在设立这些反馈装置的时候，是有一个用来进行感觉的量器来测量刚刚作出的金属板的厚度，然后把这个信号传送回某种补助马达，这个补助马达控制的是一个单一变量，也就是牵引力——这个变量是最后影响钢板的因素，就在卷板机之前。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
