Übersetzung für "Beam blank" in Deutsch

Successful applications can also be found in Beam Blank and Round casters.

This clear reduction in manufacturing costs is particularly noticeable in the case of a chill tube in a beam blank format.

Here too, a plate mold or a tube mold or a beam blank may be involved.

Each end wall 7, 8 has a projection 7a, 8a which projects into the mold space and which form a recess 1d in the beam blank 1.

The cast beam blank 1 has a middle web 1a which widens with an angle a=60° toward a lateral increased thickness portion 1b each.

SUMMARY OF THE INVENTION It is an object of the invention to develop a mold/chill tube having a double T-shaped inner and outer cross section in beam blank format for the continuous casting of metals, in which local overheating of the transitional regions is avoided, and thereby a longer service life is achieved.

With curved continuous casting of preliminary profiles, in particular double T preliminary profiles or beam blank preliminary profile strands which have a bar and two side flanges, the cooling water is collected between the flanges on the inside of the radius in the preliminary profile strand and can only run off downwards along the preliminary profile strand.

According to a possible embodiment, beam cutting can be carried out in such a way that a beam-cut blank initially remains connected to the strip material by means of at least one web.

In this regard it is advantageous if, with reference to the forward feed of the strip, at least a first web is arranged in the front first third of the beam-cut blank, and that at least one second web, with reference to the forward feed of the strip, is arranged in the rear third of the beam-cut blank.

The object forming the basis of the invention is to provide a mould for large-sized sections which are particularly suitable for the casting of large T-shaped preliminary sections or beam blank formats because they satisfy the associated casting requirements with regard to the tapering of the mould passage.

If a chill tube in beam blank shape is installed, the inner contour of the water-guiding jacket has also to correspond to the outer contour of such a shape.

However, in the case of chill tubes in beam blank format, the problem arises that the cooling bores transverse to the longitudinal extension can be applied to the chill tubes only with great effort.

Device in accordance with claim 5, wherein the suction head (1) is an exchangeable head having quick disconnection and connection devices (3), so that the suction head can be adapted to other beam blank formats (9).

Device in accordance with claim 5, wherein a manipulator is provided for positioning the suction head (1), whereby the suction head (1) can be positioned at a distance of 0-40 mm from the surface of the beam blank section.

Device in accordance with claim 5, wherein brushes are provided for sealing and guiding the suction head (1) against the beam blank section (9).

Since large beam-blank formats are cast more slowly than smaller formats, they require a relatively large conicity in the mould.

Continuous casting plants of this type are used, for example, for producing large so-called beam-blank formats with a double-T profile of over 800 mm length, over 400 mm width of flange and approximately 120 mm web thickness.
