Definitions

• Support roller stand for metal, especially steel continuous casting plants
• the invention relates to a support roller stand for metal, in particular continuous steel casting plants. According to the preamble of claim 1.
• a generic supporting roller frame is known from DE 196 06 308 B1.
• This support roller stand is divided into straight or curved segments with roller carriers, with several rollers being combined on one roller carrier.
• Two roller supports designed as a rigid frame element in the form of a sheet metal welded construction for parallel end faces are fastened to holding elements running on both sides next to the cross section of the casting strand.
• the rollers are supported on both sides in bearings, the housings of which are in turn connected to the roller carrier.
• Both frame elements have a cantilevered extension at each end, between which one in the form of a sheet metal
• Welded side element is pressed and detachably connected to the two frame elements via expansion screws.
• the bending and torsion-resistant support roller segment thus formed has smooth and flat inner surfaces.
• Both frame elements are provided with carriers which extend in the direction of the strand and are T-shaped and on which the respective bearing housing is detachably fastened.
• the cooling medium supply and removal are integrated in the frame element and the likewise cooled bearing housing is connected to the cooling medium supply and removal via a passage arranged in the T-shaped support.
• a disadvantage of this known support roller structure is the difficult accessibility in the event of a defective roller or a defective bearing.
• Another disadvantage is the type of cooling medium guidance in the frame element, since that of the the respective coolant flowing back is passed several times through the frame part.
• the object of the invention is to provide a support roller frame for metal, in particular continuous steel casting plants, which is more easily accessible with the same bending and torsional rigidity in terms of simplified maintenance and can optionally be used for a dry and wet driving style. Another task is to simplify the cooling medium guidance in the frame element.
• Carrying element has at least two tubes lying parallel and at a distance from one another and transversely to the strand running direction.
• a stiffening web plate is welded in between the tubes.
• the pipes act as coolant supply and discharge, which are provided with a connection piece on the outer surface.
• connection of the frame elements thus formed to the side elements takes place via the cantilevered extension known per se, which, adapted to the pipe construction, has a peg-like section which can be pressed into the pipe and then has a flat section resting on the narrow sides of the side elements facing the frame elements.
• the frame element has three tubes arranged symmetrically at a distance as a support element, the middle tube being provided with a connecting piece for the spray water.
• a wet driving style of the support roller frame can thus also be selected in a simple manner.
• these have a coaxially arranged displacement tube, which has a smaller outside diameter than the inside diameter of the support element.
• Figure 2 is a side view of Figure 1
• Figure 3 shows a section C-D in Figure 1
• Figure 4 shows a section E-F in Figure 1
• FIG. 1 shows a section of FIG. 2 and a side view of the segment of a support roller stand designed according to the invention.
• a curved segment for a continuous sheet caster is shown.
• This segment has three symmetrically arranged tubes 1 - 6 forming the upper or lower frame element as the supporting element.
• the pipes 1 - 6 are transverse to the direction of the strand.
• web plates 7-10 are arranged.
• the outer tubes 1, 3 and 4 in each case, holding plates 1, 12, 13, 14 which face the strand are attached to the outer lateral surface. Between these
• Retaining plates 11, 12 and 13, 14, a carrier is attached, which has three sections 15.1, 15.2, 15.3, 16.1, 16.2, 16.3. Three pairs of rollers are fastened to each support section by means of screws. A total of nine pairs of rollers 17, 17 '- 25, 25' are provided in this segment.
• the respective frame element is thus formed by three tubes 1 - 3 or 4 - 6, intermediate web plates 7, 8 or 9, 10, external holding plates 11, 12 or 13, 14 and beams 15.1 - 15.3 or 16.1 - 16.3.
• the pipes 1 - 3 and 4 - 6 are with at both ends projecting extensions 26, 26 '- 28, 28' and 29, 29 '- 31, 31'.
• Each extension has a peg-like section 32, 32 ', 33, 33' which can be fitted into the respective pipe 2, 5 and then has a flat section 34, 34 ', 35, 35'.
• the latter section 34, 34 ', 35, 35' is designed such that a side element designed as a sheet metal welded construction
• a spray water line 50, 50 ', 51, 51' is provided in order to be able to operate the segment even in a wet driving style (FIG. 4).
• the middle tube 2, 5 each has two connecting pieces 52, 52 ', 53, 53', which are arranged on the outer surface of the tube 2, 5.
• all pipes 1-6 are provided with a coaxially arranged displacement pipe 54-59, this displacement pipe 54-59 having a smaller outer diameter than the inner diameter of the respective one Pipe 1 - 6.
