在捷克,为了改善测量仪表和自动化元件所存在的缺乏现状,曾设立一所专为发展并制造这些仪表和元件的工厂。一、轧辊位置自动记录器为了控制并改进轧钢工艺过程,现已造成一种可靠的仪器,它能够准确的记录出上轧辊每一移动的位置。轧钢机轧辊位置的指示盘,是与轧辊调节螺杆相连接,并且跟着调节螺杆而移动。这移动被转变为电冲(图1)。我们它可以应用“自同步机”来直接地指示出角 In the Czech Republic, in order to improve the lack of current status of measuring instruments and automation components, a factory dedicated to the development and manufacture of these instruments and components has been established. First, the roll position automatic recorder In order to control and improve the rolling process, has now created a reliable instrument that accurately records each roll on the location of the roller. Roller mill roll position indicator plate, is connected with the roll adjusting screw, and follow the adjusting screw to move. This movement is converted to an impulse (Figure 1). We can use “self-synchronous machine” to indicate the corner directly
