Abstract
The present invention discloses an arrangement for cooling a roll (5). The arrangement comprises a housing (2) to be secured to the roll (5), a hollow shaft (8) mounted for rotational movement within the housing (2) and a cooling medium line to convey cooling medium into the roll (5) via the interior of the shaft(8). The cooling medium line comprising an inlet communicating with an elbow portion, a first length (27) of the elbow portion (20) extending from the inlet substantially perpendicular to the axis of the shaft and a second length (26) of the elbow portion extending from the first length in the direction of the axis of the shaft (8), the axes of the first and second lengths being in substantially the same plane.
Claims23
An arrangement for cooling a roll, the arrangement comprising:
- a housing to be secured to the roll, the housing mounted for rotation about a hollow shaft of the roll, the shaft having a length and a longitudinal axis;
- a cooling medium delivery flowpath being provided in an elongate cooling medium line conduit extending into the roll and delivering cooling medium into the roll;
- a return flowpath for outflow of cooling medium out of the roll to an outlet such that at least part of the elongate cooling medium line conduit is positioned in the interior of the shaft along the longitudinal axis of the shaft, wherein the return flowpath is defined between an outer surface of the elongate cooling medium line conduit and an internal surface of the shaft;
- wherein the elongate cooling medium line conduit is connected to an elbow portion, a first length of the elbow portion extending from an inlet substantially perpendicular to the longitudinal axis of the shaft and a second length of the elbow portion extending from the first length in the direction of the longitudinal axis of the shaft, the elongate cooling medium line conduit being connected to the second length of the elbow portion;
- and
- wherein the elongate cooling medium line conduit and the elbow portion remain stationary as the housing rotates.
