The Retrofit of Extraordinary Pressure in Hydraulic System
for Hot Leveller of Plate Mill
Abstract
The hydraulic system for the hot leveller in the plate mill of the PH steel plant is to improve the flatness of the hot-rolled plate. This study analysed the reason of the extraordinary peak pressures and differential pressures occurred between four synchronous unjamming cylin
