Problems solved by technology

[0004] However, the solution known from said international patent application WO 2013 / 048836 A1 for arranging the low-pressure pump remote from the rolling mill stand is not meaningful for different reasons:
[0005] On the one hand, the required low-pressure line for connecting the low-pressure pump to the low-pressure channel in the fitting is relatively long

Embodiment Construction

[0033] The invention is explained in detail below by way of example with reference to the mentioned drawings. In all figures, the same technical elements are identified with the same reference numerals. The reference number 140 is also representatively used for all variants of the reference number, i.e., representing 140', 140", 140-1, 140-2, 140-I, 140-II, 140-III and 140-IV A similar situation applies for reference numeral 130 .

[0034] all attached figure 1 and 4 Figures 7 to 7 show four-high rolling stands 100 as examples, which respectively have a roll stand 100' on the drive side and a roll stand 100" on the operating side. Each roll stand has two supporting rollers, which are arranged in The four roll necks 110 are respectively rotatably supported in oil film bearings 120. Each oil film bearing 120 has a low-pressure input pipeline 122 and a low-pressure discharge pipeline 124. The return part is led back to one or more tanks 140; The inlet is supplied by the corre...

Abstract

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 backup 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 hasat 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 barrel-remote side of at least one of the chocks in order to rotationally couple the at least one low-pressure pump (130) to the backup roll journal (120) which is rotatably mounted in the chock.

Description

technical field [0001] The invention relates to a rolling mill stand for rolling rolling stock, preferably metal. Furthermore, the invention relates to a rolling mill train having a plurality of rolling stands. Background technique [0002] Such rolling stands are known in principle from the prior art, for example from document WO 2013 / 048836 A1. The rolling mill stand disclosed here for rolling metal rolling stock discloses a roll having two roll necks, each of which is mounted rotatably in an insert, also referred to as bearing housing. In this case, the roll necks are supported in cylindrical receiving spaces in the insertion part in the heavily loaded machine frame. Known rolling stands are coupled with low-pressure circuits for coolants and / or lubricants. [0003] A low-pressure circuit for coolant and / or lubricant comprises a low-pressure pump and a tank for coolant or lubricant, both of which are typically arranged remotely from the rolling stand, for example in th...
