  • Patent number: 10974297
    Abstract: The invention relates to a rolling stand for the rolling of metallic rolling stock. The rolling is achieved with the aid of a roll of which the two roll journals (112) are rotatably mounted in recesses (122) of chocks (120). The recesses are supplied with coolant and/or lubricant via a high-pressure inlet (124) and at least one low-pressure inlet (126). The high-pressure inlet is fed via high-pressure conduits (132) from a high-pressure pump (130). To reduce the costs for driving the high-pressure pump in relation to the prior art, the invention provides that the high-pressure pump is rotationally coupled to the roll journal via a gear mechanism in order to be driven thereby.
