三菱重工业公司发明一种板轧机轧辊偏心控制装置(MARECS=商品名),该装置能把由轧辊偏心而引起的板厚变化30～80微米减少30～60％。该装置是能把至今被认为难以控制的由轧辊偏心所引起的板厚变化控制到微米精度的装置。不久前第一台产品装在新日本钢铁公司名古屋钢铁厂,正在正常运转。该装置的特点是把以波形所反应的轧辊偏心变成控制信号,再通过微型计算机进行处理和控制。用该公司这种独创的波形检测法,能
Mitsubishi Heavy Industries Co., Ltd. invented a roll stand roll eccentricity control device (MARECS = trade name) which can reduce the thickness variation by 30 to 80 μm by 30 to 60% due to eccentricity of rolls. The device is a device that can control the variation of the thickness caused by the eccentricity of the roll up to the micron precision, which until now has been considered difficult to control. Not long ago the first product was installed at the new Japanese steel company Nagoya Steel Works, is in normal operation. The device is characterized by the waveform of the reaction of the eccentric roller into a control signal, and then through the microcomputer for processing and control. With this company’s original waveform detection method, can
