Definitions

• the invention relates to a strand guide, in particular for a slab caster for steel, with support segments in which frames are arranged, which have opposite rows of guide and drive rollers and which are held against one another via anchors.
• a strand guide is known with a plurality of support segments carrying rollers.
• the support segments are in one piece
• Support lugs and fitting bolts are provided, which are manufactured and arranged in such a way that this roll misalignment is also avoided during installation and removal.
• the roller segments themselves are permanently installed as a closed unit.
• the invention has set itself the goal of avoiding the disadvantages mentioned above and of creating a strand guide, in particular for a slab caster for steel, which, with a simple construction, ensures self-centering with at least one of the opposing frames of the individual support segments to form the strand without play.
• links are provided which are arranged conically to one another at an opening angle and which are fastened on one end via holding elements at the end of a frame and on the other end at at least one fixed point.
• the handlebars are attached to the upper frame, while the other end are attached to the arcuate side member of the continuous caster or preferably to the lower frame.
• the opening angle of the two handlebars can be up to 60 °.
• the conical opening is preferably arranged in the strand guide direction.
• console-shaped extensions can be provided on the upper frame.
• connection between the handlebar and bracket on the frame are designed as joints or as non-rotatable brackets.
• bracket handlebars which are designed as rods, which are constructed from a tensile and compressive forces and a lateral deformation-bearing material. Bundles of rod or strip-shaped material are used for this, which have a square, polygonal or even round cross section. Intermediate layers are provided to avoid fretting corrosion between the individual link elements.
• the configuration according to the invention also facilitates the implementation of the dynamic mouth width adjustment during the casting operation. This is particularly advantageous in the case of so-called soft reduction.
• the use of handlebars in a continuous sheet caster significantly increases the freedom of movement of the upper frame to the lower frame, particularly with regard to the degrees of freedom of tilting about the horizontal axes.
• the schematic Figure 1 shows two frames arranged in parallel, one
• FIG. 2 shows a support segment of a continuous caster with an upper frame 11 and a lower frame in the case of a continuous caster. In the present drawing, only the rollers 22 of the subframe are shown.
• the frames 11 and 12 are connected to one another via anchors 31 to 34, each of which has a hydraulic device 35 to 38.
• the upper frame 11 has, on its end 13, console-shaped extensions 15 on both sides. Pins 46 are provided on the extension 15, which have a joint 48 in the right side of the sketch and a holding element 43 on the left side as a connection to the links 41, 42 exhibit.
• the links 41, 42 are attached at the other end to the frame 12 via a holding element 44 or a joint 49 with a pin 47.
• FIG. 3 shows the top view of the rollers 21 of the upper frame 11 (shown in broken lines) with the strand S carried out underneath.
• the links 41, 42 arranged on both sides of the support segment have the holding elements 43, 44 or the joints 48, 49 at the head end.
• handlebars are used, which are attached to the upper or lower frame via non-rotatable brackets 43, 44.
• the conical arrangement of the links 41, 42 aligns the upper frame with its continuous casting rollers in such a way that it is centered on the strand S.
• FIG. 4 shows a handlebar 41 which is designed as a bar 51.
• the individual strips are arranged such that at least one narrow side 52 is inclined towards the strand and the broad sides 53 are connected to one another via intermediate layers 56.
• a holding head 54 is non-positively attached to the handlebar 41.
• the holding head 54 has an opening 55 which corresponds to one of the pins 46, 47 (see FIG. 3) of the upper and lower frame.
