Definitions
- the invention relates to a casting roll for a thin-strip casting plant, in particular for Continuous casting of thin strips of steel, having a substantially cylindrical core, with a sheath of copper or a copper alloy, optionally with the outside at least one coating is provided, with an internal cooling and with a Adjustment device for adjusting the outer contour of the casting roll in the end-side end regions thereof.
- a casting roll of this kind is known, for example, from EP-A-0 664 173.
- casting rolls of this type are found in the continuous casting of refractory metals, such as steel, Application.
- two casting rolls of this kind are arranged parallel to each other and rotated in opposite directions about their respective axes.
- the molten metal is in cast a gap defined between the casting rolls and upon contact with the Surfaces of the casting rollers provided with an internal cooling as well as when passing through the gap is cooled and solidified so that the metal in the form of a substantially solidified strip emerges from the casting gap.
- the tape thickness is determined by the width of the G fauxspaltes and the bandwidth through the length of the G fauxspaltes, the end of the casting End faces of the casting rolls adjacent sealing surfaces is limited determined.
- conically tapered in the casting rolls Provide piston.
- These conically tapered pistons are in two at each in the displaceable opposite ends of the casting roll arranged Kolbengleit till used, so that by moving the conically tapered piston in the axial direction the Outer circumferential surface of the casting roll under the wedge effect of the conically tapered piston is deformed.
- the pistons depending on the position in the Kolbengleitirriate at different points in the longitudinal direction of the casting roll Forces on the casting roll, i. the mantle of the casting roll, exercise, creating a exact compensation of Walzenballmaschine, if at all, is very difficult.
- the invention aims to avoid these disadvantages and difficulties and provides the task of creating a casting roll of the type described above, with it manages to reduce thermal crowning with structurally simple means or to Complete balance.
- the casting roll for a continuous operation robust enough and be less susceptible to interference.
- the construction should be inexpensive to manufacture and ensure easy operation.
- a backing disk is known per se from US-A-5,613,546 for a casting roll, however engages this support disk directly on the shell of the casting roll and is not used to compensate of thermal crowning, but for centering the shell against the core.
- the ring is opposite to both the shell as also sealed to the core by means of a seal.
- This will be an absolute Tightness of the internal cooling of the casting roll ensured.
- Such a tightness is for example, in a construction according to JP-A - 60-27446 not readily given.
- the conically tapered pistons are within provided on the core and surrounded on the outside by the cooling system for the jacket. As a result, a widening of the shell by means of the piston causes a radial displacement of the Inlet and outlet pipes for the internal cooling of the jacket.
- the support disk on its outer peripheral surface with a Truncated cone surface, which at a counter-jaw surface, the ring at the inside peripheral surface is provided, is applied
- a structurally simple to manufacture and reliable embodiment is characterized characterized in that for adjusting the support disk in the longitudinal direction of the casting roll a Plural distributed in the outer periphery of the support disk arranged screws is provided, with which the support disk is adjustable relative to the core, wherein Advantageously, the screws are screwed into arranged at the core blind holes. in this connection the setting of the support discs is made before pouring.
- a further preferred embodiment is characterized in that the support disk adjustable by means of a ring nut relative to the core in the longitudinal direction of the casting roll is.
- the support disk relative to the core in Lengthwise of the casting roll hydraulically adjustable.
- the ring extends to a maximum of 75 mm from the front end in Longitudinal direction of the casting roll to the center, preferably up to 50 mm, in particular to 35 mm.
- the jacket has in its end-side end portions, in which a contact with given the ring, a thickness less than or equal to 50 mm.
- the Steel drum 1 and the core 1 is with passages for an axially zu- and ab classifiedbares Provided coolant.
- This core 1 is on the outside of a jacket 2 made of copper or surrounded a copper alloy, wherein the thickness of the jacket 3 between 40 and 45 mm lies.
- the jacket 2 has on the inside of coolant flowed through coolant channels 4, so that an intensive heat dissipation through the jacket 2 is possible.
- the length of the casting roll is about 1 to 2 m, casting rolls are currently preferred with Lengths from 1100 to 1600 mm built.
- the jacket is provided with a nickel or chromium coating 5. These Coating 5 also extends over the end faces 6 of the jacket.
- the front end areas 7 of the shell 2 protrude over the steel drum respectively core 1 in Longitudinal direction of the casting roll, u.zw. up to max. 75 mm, preferably less than 50 mm.
- a ring 8 rests on the jacket 2 on the inside, wherein between the outer circumferential surface 9 of the ring 8 and the jacket 2 a Seal 10 is provided, which is inserted into a circumferential groove 11 of the ring 8.
- the ring 8 by means of screws 12 in the axial direction of the casting roll on the core. 1 fixed and opposite the core 1 also by means of a seal 13, which in an annular groove 14th is inserted on an inner side surface 15 of the ring 8, sealed, so that coolant, which via the core 1 in the coolant channels 4 of the shell 2 and in turn back in the core 1 flows, is prevented from emerging from the casting roll.
- the directed to the rotation axis inner peripheral side 16 of the ring 8 is frustoconical, u.zw. tapered towards the center of the casting roll.
- Truncated cone surface 16 is an annular support plate 17 having an outer peripheral surface 18, which is also frustoconical, u.zw. opposite to the frusto-conical surface 16 of the Ring 8, designed, on.
- This support plate 17 is in the illustrated embodiment by means of several screwed in blind holes 19 of the core 1 screws 20 in Axial direction of the casting roll adjustable, causing it to a widening of the ring 8 and thus to a widening of the end-side end portion 7 of the shell 2 in the desired Scale comes.
- the screws 20 are in the vicinity of the outer periphery of the annular Support disc 17 provided to deflections or bulges of the support plate 17 to avoid.
- a particular advantage of the construction according to the invention is the fact that a Adjusting the profile of the casting roll generators depending on the planned and / or current casting or solidification conditions is made possible, so that the respective suitable or acceptable band thickness cross profile can be generated in the edge region can, without complex processes of machining, such as turning and Grinding, to require.
- a very hard thin Surface coating 5 e.g. a chromium layer on the shell 2
- this is of great Advantage since each cutting profile adjustment also a new coating of the shell 2 would require.
- a cutting profile adjustment would also be Plant downtime required to perform the necessary casting roll changes to be able to.
- several G manwalzencrue would be kept in stock. According to the invention thus lower investment and storage costs and a result lower proportion of system downtime.
