2.轧辊位置自动控制位置自动控制(简称APC)是生产过程自动化中应用最广泛的控制技术之一,用计算机对机械部件的位置进行直接的数字控制称为位置直接数宇控制(简称位置DDC)。在轧钢厂用位置DDC进行控制的对象很多,例如,轧辊压下位置、立辊开口度、导极开口度、板坯自动定位、推钢机及出钢机的行程位置等。利用阀门位置的大小控制气体、液体的流量,也可以用位置DDC实现。本文主要介绍轧辊位置DDC(俗称APC)。 2.1 控制系统的组成在图1中,DDC计算机代替了调节器
2. Roll position automatic control Automatic position control (referred to as APC) is one of the most widely used control technology in the production process automation, the direct digital control of the position of the mechanical components by the computer is called the position direct digital control (referred to as position DDC ). DDC in the rolling mill to control the location of many objects, for example, the roll pressure position, the vertical roll opening, the opening of the pole, slab automatic positioning, pusher and tapping machine stroke position. The use of the size of the valve position control gas, liquid flow, you can also use the location of DDC. This article describes the roll position DDC (commonly known as APC). 2.1 The composition of the control system In Figure 1, DDC computer instead of the regulator
