| Abstract: | In the paper, the causes that the first three rolls of PQF continuous mill age and wear earlier as well as the fracture of rolls are analyzed. According to the actual situations at field,the micro tension rolling method for PQF continuous mill is formulated based on the operating state of rolling, situations of aging and wear for roll surface as well as forms for fracture of mrs, which could make the aging and fracture of rolls reduced as well as service life of rolls improved, |
