10974297 · 2021-04-13 · ·

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.

The invention relates to a rolling stand and a rolling mill for the rolling of preferably metallic rolling stock. Known rolling stands of this type typically have two back-up rolls (110) which are rotatably mounted by way of their roll journals in chocks which function as oil film bearings. The oil film bearings are supplied with coolant and/or lubricant by means of a low-pressure circuit which has at least one low-pressure pump (130) for conveying the coolant and/or lubricant. To reduce the costs for driving the low-pressure pump (130), there is provided according to the invention a gear mechanism which is arranged on the roll face-remote side of at least one of the chocks in order to rotationally couple the at least one low-pressure pump (130) to the back-up roll journal (120) which is rotatably mounted in the chock.
