| Abstract: | In 2009 in No. 2 Steel Rolling Mill of Wu Steel the accidents of plunger piston of roll shifting cylin- der of finishing mill broken frequently occurred, made a great difficulty for production, caused a large con- sumption of spare parts and high cost. It is analyzed the main reason, proposed improving measures. The problem was effectively solved and the utilization cycle of roll shifting cylinder was prolonged from 1.5 to 6 months, guaranteed the fast production. |
