一、前言轧机的轧制力是金属轧制生产中的重要参数,测量轧制力对提高轧机的经济效益,制订合理的操作工艺,提高产品质量都具有非常重要的意义。轧机轧制力的测量可采用压磁式、应变式、电容式、电感式等方式。电容式测压仪与其它测压仪相比具有如下特点:1.耗电量小,无自热现象;2.结构、工艺简单;3.传感器强度高,过载能力强;4.弹性体尺寸限制小, I. INTRODUCTION Rolling force of rolling mill is an important parameter in metal rolling production. It is very important to measure the rolling force to improve the economic benefits of rolling mill, to formulate a reasonable operation process and to improve the product quality. Rolling mill rolling force measurement can be used, strain, capacitance, inductance and other means. Capacitance manometer and other manometry compared with the following characteristics: 1. Small power consumption, no self-heating phenomenon; 2. Structure, process is simple; 3. Sensor strength, overload capacity; 4. Elastomer size Limit small,
