Benefits of technology
[0009]In other words, according to the invention the rib-shaped supporting profiles arranged on the outer surface of the mold are formed with a plurality of spaced-apart undercut grooves into which engage the connectors that also have a cylindrically tubular body with an internal threaded bore that receives a fastening screw for fixing the jacket. This jacket consists of a plurality of plates that are connected indirectly to the mold tube via screws that engage into the cylindrically tubular body, for which purpose the latter has a corresponding threaded portion. The hollow body is mounted positively inside the recesses on the rib-shaped supporting profiles. The jacket plates can thereby be assembled quickly and in a labor-saving way, since the correct positioning is already defined by only two connection points, and the jacket plate is prevented from being axially displaced longitudinally with respect to the mold tube. The other fastening screws can subsequently be fitted without difficulty.
[0011]According to a first advantageous embodiment of the present invention, the grooves with undercuts and the parts engaged therein of the connectors are T-profiles or dovetail profiles. Such profile cross sections can be produced simply, quickly and therefore cost-effectively and, moreover, provide an optimal hold of the connectors.
Problems solved by technology
A particular problem with continuous casting is that uniform and careful cooling of the copper tubular mold is advantageous for this purpose.
The molds described have the disadvantage, in the first place, that manufacture or machining is relatively complicated, thus increasing the production costs.
Moreover, assembly is comparatively complicated, since the respective strips have to be oriented first parallel to one another and then at the correct height, which has proved to be difficult.
A particular problem, however, is that a reduced cooling action takes place in the region of the profile strips, thus leading to the sharp local temperature gradients already referred to.

Embodiment Construction
[0020]According to a first actual embodiment of the present invention, the mold consists of a mold tube 1 and of a jacket 2. The mold tube 1 has supporting profiles 3 distributed over its outer surface and extending in a longitudinal direction 4, so that the mold tube 1 is supported via these in the jacket 2. Furthermore, the side walls of the mold tube 1 are formed with outwardly open cooling grooves or passages 5 that also extend in the longitudinal direction 4 and through which a coolant flows.
[0021]FIG. 2 shows a view of a detail of one planar side wall of the mold tube 1 with the supporting profiles 3 and with the coolant passages 5. It can also be seen there and in a view of a detail in FIG. 3 that a plurality of transverse spaced-apart grooves 6 with undercuts 7 are provided at least partially on the is supporting profiles 3. Connectors 8 engage here, each having a cylindrically tubular body 9 with an internal threaded bore 10 that receives a fastening screw (not illustrated ...

A continuous-casting mold has an inner mold tube having a plurality of side walls formed with coolant passages and a plurality of profiles extending longitudinally on each of the side walls and each formed with a respective plurality of longitudinally spaced undercut grooves. An outer jacket surrounds the mold tube. Respective connectors each have a base generally complementarily fitting in a respective one of the grooves and a tubular and internally threaded body projecting outward from the respective base. Respective screws engage from outside through the jacket into the bodies.
Description
FIELD OF THE INVENTION[0001]The present invention relates to a mold for the continuous casting of blooms, slabs or billets, with a mold tube surrounded by a jacket and supported by profiles running in the longitudinal direction and distributed over the circumference on the jacket and connected positively to the latter via connectors, cooling passages for the routing of cooling water being distributed over the entire circumference between the jacket and being arranged essentially over the entire mold length.BACKGROUND OF THE INVENTION[0002]Continuous casting molds are reusable, downwardly open molds for casting metal or alloys. For this purpose, the liquid metal or liquid alloy is conducted through the mold that consists of cooled copper plates and the metal or alloy solidifies in the desired form.[0003]A particular problem with continuous casting is that uniform and careful cooling of the copper tubular mold is advantageous for this purpose. To this effect, coolant is conducted thro...
