Definitions
- the invention relates to a continuous casting plant for casting a metal strand with billet or billet cross section with a usable in a Kokillentragrahmen, changeable and oscillating mold for forming a metal strand and adjacent to the mold strand guide for supporting and guiding the metal strand, wherein the strand guide two or more strand guide segments and each strand guide segments is supported via a segment support frame in the plant structure of the continuous casting and a immediately following in the strand guide of the mold first segment support frame at least two strand guide segments supported.
- disruptions to operation may occur due to a strand break-through, whereby melt exits between the mold and the first strand guide segment arranged downstream of the mold and damage preferably occurs at this strand guide segment, which requires a possibility of a rapid segment change.
- the object of the present invention is therefore to avoid the disadvantages of the known prior art and in a continuous casting of the above described type to improve the adjustment of the individual successive strand-forming and strand-supporting components to each other and adapt to different maintenance requirements.
- This object is achieved in a continuous casting of the type described above in that the first of the mold directly subsequent strand guide segment releasably secured to the first segment support frame to substantially vertical support surfaces and regardless of the subsequent strand guide segments from the continuous casting and off is built into this and that at least the last supported on the first segment support frame strand guide segment forms only together with this an assembly and off the continuous casting and is designed to be installed in this.
- the at least last supported on the first segment frame strand guide segment with the segment frame a unit and as such, preferably exclusively as such, from the continuous casting and trained in this trained.
- connection hooks are arranged on the module.
- the substantially vertical support surfaces are oriented parallel to the strand conveying direction.
- a very expedient embodiment of the invention is that the first strand guide segment after a successful removal of the mold and after the release of fasteners from the substantially vertical support surfaces substantially vertically upwards by the mold accommodating mold cavity is designed expandable.
- the free mold space occupied by the mold is dimensioned such that the expansion of the segment support frame with a mounted or connected to it Strand guide segment with, for example, a hall crane through this free Kokillenraum is possible.
- the first strand guide segment after releasing fasteners together with the mold substantially vertically upwardly form.
- cooperating support surfaces are provided, for example, on the mold and the first strand guide segment, which produce a supportive contact with the mold during an upward movement of the first strand guide segment and entrains the mold during the upward movement of the first strand guide segment.
- the first strand guide segment is releasably secured to the first segment support frame and each further strand guide segment supported on the first segment support frame is fixedly connected to the first segment support frame. At least another strand guide segment is firmly connected to the segment support frame.
- the first segment support frame forms an extension of the outer arch frame of the detachable strand guide segment subsequent
- Strand guide segment The extension of the outer arch frame of the one strand guide segment extends in the direction of the mold and carries the substantially vertical support surfaces for the further strand guide segments arranged between the mold and the connected strand guide segment.
- all strand guide segments supported on the first segment support frame are detachably fastened to this segment support frame.
- at least the last strand guide segment in the strand conveying direction together with the segment frame can be installed or removed as a structural unit in the continuous casting plant. But it can also all mounted on the first segment frame Strand guide segments together with this as a unit in the continuous casting and on this expanded.
- At least the first strand guide segment in it rotatably mounted strand guide rollers on the metal strhack both in the direction of its width extension and in the direction of its thickness extension adjustable are formed.
- This employment preferably takes place with hydraulic adjusting devices. These act on the one strand side associated strand guide rollers, which are grouped together on a roll holder rotatably supported.
- the strand guide rollers are assigned spray nozzles for coolant application to the surface of the metal strand, which are aligned in the direction of width extension and in the direction of the thickness extension of the metal strand to different thicknesses and widths with a Spritzdüsen- adjustment.
- the last strand guide segment supported on the first segment support frame is provided with strand guide rollers which are adjustable against the metal strand at least in the direction of its thickness extension.
- 1 is a mold and a first portion of the strand guide of a continuous casting plant according to the invention according to a first embodiment of the invention
- 2 shows a mold and a first section of the strand guide of a continuous casting plant according to the invention according to a second embodiment of the invention.
- Figures 1 and 2 show a schematic partial view of a continuous bloom ingot with a mold 1 and a subsequent strand guide 2, the strand guide segments comprises, of which only the immediately adjacent to the mold 1 strand guide segments 3a, 3b, 3c, 3d, 3e, 4th are shown.
- the same reference numerals are assigned to the same components.
- the mold 1 is either a tubular mold, mainly for the casting of a metal strand with billet cross-section, or as Plattenkokille, mainly for the casting of a metal strand with Vorblockquerites formed.
- the mold 1 is equipped with a state of the art, not shown internal cooling and suspended oscillating on a Kokillentragrahmen 5.
- the metal strand is passed through the strand guide 2 formed by strand guide segments and supported and guided by strand guide rollers 6a, 6b, 6c.
- the strand guide segments 3a, 3b, 3c, 3d, 3e, 4 are suspended via segment support frames 7, 8 in the plant support structure 9 in each case via a fixed bearing 10 and a floating bearing 11.
- the first of the mold 1 in strand conveying direction R immediately following segment support frame 7 carries three segments 3a, 3b, 3c, which supported on substantially vertical, or parallel to the strand transport direction aligned support surfaces 12 of the segment support frame 7 and fastened with fastening means 13 to this releasably.
- the first of the mold 1 in the strand conveying direction R immediately following segment support frame 7 carries two strand guide segments 3d, 3e.
- the first strand guide segment 3d is at substantially vertical, parallel to the strand conveying direction aligned support surfaces 12 of the segment frame 7th supported and secured with fasteners 13 to this releasably.
- the following strand guide segment 3e comprises an outer arch frame 14 in which the strand guide rollers 6a are supported, and an inner arc frame 15 in which the strand guide rollers 6b are supported.
- the outer arch frame 14 is in this case formed so that it simultaneously forms the segment support frame 7 for the strand guide segment 3e. He is thus an integral part of the strand guide segment 3e and extends against the strand conveying direction to the mold 1 and also forms the segment support frame for the first segment 3d.
- the basic structure of the strand guide segments allows adaptation to different strand thicknesses by the inner arc frame 15 can be positioned in the direction of the fixed outer arch frame 14 with hydraulic actuators 17.
- strand guide segments 3a, 3b, 3c may also be used which have strand guide rollers on all sides of a metal strand with a rectangular or square strand cross-section and which extend both in the direction of Thickness extent and in the direction of the width extension of the metal strand to this cross-sectional format are adjustable.
- strand guide segment 3e associated with cooling nozzles with spray nozzles 18, which are equipped with a spray nozzle adjustment, which follows an automated format adjustment and thus ensure always centric coolant application to the variable in width side surfaces of the metal strand.
