Definitions
- the invention relates to a method for producing hot-rolled hollow sections made of steel according to the preamble of claim 1. Furthermore, the invention relates to a hollow profile produced according to this method according to claim 5 and the
- the known as MSH ® profiles hot rolled hollow sections may be from
- a round tube is first produced from a steel strip formed to a slit pipe, generally by means of HFI welding, which after heating to deformation temperature in corresponding
- Profile rolling stands is hot rolled to a hollow profile.
- EN 10210-2 does not specify the outer radii of curvature but the lengths of the rounding areas, referred to below as visible edges.
- Second moment of inertia and a greater flexural and torsional stiffness results in connections in the profile edge region a smaller weld gap and thus a more appealing appearance, which is very important in visual constructions.
- a force can be introduced at least partially rectilinear in a profile wall parallel to the force when the
- Visible edge is smaller than the wall thickness, which is advantageous for the static design.
- the tower elements are made of square or rectangular hollow sections
- z. B the lower chords of the boom of trolley tower cranes to obtain a wider bearing surface for the trolley rollers or generally when loaded on bending profiles, z. B. for the well-known from DE 10 2007 031 142 crane runway support system made of steel for high
- hollow profiles welded together for example, consisting of two L-shaped legs, which have very small visible edge lengths of ⁇ 1.0 ⁇ t and have thus far fallen below the standard specification for hot-finished hollow sections, have been used up to now.
- the object of the invention is therefore to provide a method for producing hot-rolled
- a method is used to solve this problem, in which for a given profile cross-section introduced into the roll mill Vorrohr based on the previously default standard Nennau built manmesser an enlarged diameter, which can be reached from a degree of reduction of the front pipe and to be reached Hollow profile dimensions is determined, wherein the degree of reduction to be achieved in a range of -2.0% to -13% and is determined according to the following formula:
- Vorrohr bemessers can now be realized not only visible edge lengths of ⁇ 1, 5 x t but even visual edge lengths of ⁇ 1.0 x t or ⁇ 0.6 x t.
- Roll stand already experiences no feed before leaving the forming zone and gets stuck in the rolling stand.
- Vorrohr donemesser, so too low a degree of reduction, the caliber filling in the radius areas is not sufficient and it is not enough small visible edge generated.
- the inventive enlargement of the Vorrohr bemessers by maintaining the required degree of reduction are thus set relatively narrow limits, with reduction degrees of -2.2% to -4.0% for submitkanteninn ⁇ 1.0 xt and ⁇ -4.0% for visible edge lengths ⁇ 0.6 xt proved to be advantageous.
- these values can even be achieved without a change in the calibration of the rolls in comparison to the use of a standard pre-pipe diameter.
- the advantage of the method according to the invention is that compared with the hollow profiles welded together from individual profiles, hot-rolled hollow profiles that can now be produced very economically can also be used for applications that could not be used there due to the visible edge lengths that were previously too great.
- the hollow profile 1 of the tower element is designed as a vertically extending tower element corner profile "corner post."
- the visible edges of the hollow profile are denoted by Ci and C 2 .
- the connection with the politicianstockenden tower element is done by means of a centrally through the opposite leg of the hollow section 1 plugged through bolt 2, which connects the Turmisseckprofile the lower with those of the tower element mounted thereon.
- the hollow profile 1 is provided in the region of the bolt connection with reinforcing tabs 4, 4 'and the bolt 2 secured by splints 3, 3' against loosening.
