  • System of supply, discharge and distribution lines for notably liquid operating media in rolling stands
    Patent number: 6539972
    Abstract: An arrangement of pipelines of a high-pressure distribution network for liquid operating media, such as lubricants, coolants, and hydraulic pressure media for control members or drives, for a roll stand having a roll housing. The pipelines are supply pipelines, discharge pipelines, and distribution pipelines, wherein the roll stand has several consumers connected to the high-pressure distribution network for the liquid operating media. The supply lines and the discharge lines are combined to form modules of groups of pipelines mountable on the roll stand. The nominal pressure of the operating media is standardized within the pipelines of the high-pressure distribution network to a value of approximately 290 bar.
