ROLL ECCENTRICITY COMPENSATION (REC)

Rolls in rolling mills are never completely round but have eccentricity which can be caused by: • grinding inaccuracy • nonuniform thermal expansion • asymmetrical adjustment of bearing rolls shell via drive keys Each eccentricity consists of a base frequency which is the rotary frequency of the roll and several harmonic frequenciesXi'an WeiKeduo Electrical and Mechanical Equipment Co, Ltd with over 20 years experience in metallurgical industry, commits to high quality rolling process design and hot angle steel hot rolling mill manufacturing for wire rod, bar,rebar, tmt bar and other special steel production line,especially good at highspeed line design,as well China Latest Hight Production Re Roling Mills Manufacturer
