日本川崎钢铁公司知多厂1978年投产的新型中直径无缝钢管轧机,采用了先进的自动控制系统,其产品质量、成品率和生产率均有很大提高。自动控制系统配有过程控制计算机和各种在线传感器。为了进一步改进自动控制系统,川崎钢铁公司与富士电机制造公司共同合作,研制成功世界上第一台热管壁厚测量仪。最近,这种测厚仪已经用于生产。一般的所谓单壁厚测量仪,是利用超声波反射或放射线反射测量,或利用放在距管端约
Japan’s Kawasaki Iron and Steel Company Zhiduo Chang put into operation in 1978, the new medium-diameter seamless steel pipe rolling mill, using advanced automatic control system, its product quality, yield and productivity have greatly improved. Automatic control system is equipped with process control computer and a variety of online sensors. In order to further improve the automatic control system, Kawasaki Iron and Steel and Fuji Electric Manufacturing Company work together to develop the world’s first heat pipe wall thickness measuring instrument. Recently, this thickness gauge has been used for production. The so-called single-wall thickness of the general gauge, is the use of ultrasonic reflection or radiation reflection measurement,
