断辊是冷轧辊使用中较常见的失效形式之一,有的是在轧制事故(如超负荷压下,断带、叠轧、异物压入等)时断辊;有的是在正常负荷轧制时断辊。使用中发生断辊事故,必须停机换辊,延误轧制时间,影响轧制产量,早期断辊使辊耗上升,经济损失大。因此,如何减少或防止使用中发生断辊 The broken roller is one of the more common forms of failure in the use of cold rollers. Some are broken rollers in the case of rolling accidents (such as overpressure reduction, belt breaking, overlap rolling, foreign matter pressing, etc.); some are broken during normal load rolling Roller. Broken roller accident occurred in use, you must shut down the roll, delay rolling time, affecting the rolling output, the early roll off so that the roller consumption, economic loss. Therefore, how to reduce or prevent the occurrence of broken rollers in use
