| Abstract: | Working principle of the online width adjustment hydraulic system of the caster mold was analyzed, and the problem of the valve spool jamming of the reversing valve in the process of width adjustment was emphatically analyzed. Aiming at this problem, the hydraulic system is improved, and the online monitoring of the valve spool jamming of the reversing valve can be realized after the improvement. The implementation of the improvement plays an important role in reducing the breakout of steel during the mold online width adjustment . |
