Embodiment Construction

[0031] exist figure 1 The crystallizer plate is marked with 1 in .

[0032] A known arrangement of fastening threads is shown on the left, wherein this arrangement has already been mentioned above under the term "bend slot".

[0033] In this case, the fastening thread 2 is surrounded by cooling channels 4 , that is to say curved.

[0034] In contrast, in the middle figure, the fastening threads 3 are arranged in such a way that they are interrupted by cooling channels 4 or partially overlapped therewith.

[0035] Naturally there is no fastening thread in the area where the cooling channels 4 cut off the holes 3, as this also results from figure 2 , Section A-A is obvious.

[0036] For comparison, in figure 1 Also shown on the far right are fastening threads 5 which are located outside the cooling channels and thus in the monolith. In order to achieve the same breaking strength or the same load-bearing area, they need only have a smaller diameter than the fastening thread...

Abstract

The invention relates to an extrusion die having mold plates surrounding the casting cross-section, in which cooling canals extend, wherein the mold plates are connected to a water box by means of screw elements, and the screw elements are made of securing bolts having a threaded shaft, which can be screwed into securing threads in the mold plate. In order to achieve uniform cooling in such an extrusion die, the securing threads with the longitudinal center axes thereof are each disposed such that they extend between two adjacent coolant channels, wherein the diameter of each threaded bore is larger than the distance between two adjacent cooling channels, and the bores for the securing threads end at a distance to the bottom of the cooling channels, limiting the screw-in depth of the securing bolts.

Description

technical field [0001] The invention relates to a continuous casting mold comprising mold plates surrounding a casting cross-section in which cooling channels extend, wherein the mold plates are connected to a water tank by means of screw elements and the The screw element comprises a fastening bolt with a threaded shank which can be screwed into a fastening thread in the mold plate. Background technique [0002] In addition to tubular molds for billet sizes, molds for continuous casting of steel consist of a number of mold plates which combine to form a cavity. The cavity is filled and partially solidified with liquid steel and drained downwards. According to the shape of the cavity, it is divided into slab specifications, thin slab specifications, bloom specifications or special-shaped billet specifications. [0003] During casting operation, very high thermal and mechanical loads act on the individual mold plates, which almost exclusively consist of copper alloys. In o...
