Embodiment Construction

[0032] figure 1 The metal stencil 1 has a casting side facing away from the viewer and a rear side 2 facing the viewer. In the installed position, the rear side 2 is supported on a support plate, not shown in detail. During the casting operation, the hot melt on the casting side 2 should be cooled in such a way that the heat is absorbed by the metal pattern 1 and conducted away via cooling water through the cooling gap 4 in the cooling channel 5 . The casting direction of the metal formwork 1 corresponds to the vertical direction. The cooling channels 5 therefore run parallel to the casting direction from top to bottom. They extend parallel to each other.

[0033] Inside the cooling channels 5 are respectively provided inserts 6 which delimit a cooling gap 4 toward the rear side 3 . The insert 6 is U-shaped in cross section. Their inner surface 7 facing the cooling gap 4 bears against ribs 8 , which point from the cooling surface 9 of the cooling channel 5 in the directio...

Abstract

The invention relates to a metal mould plate comprising a casting side (2) and a rear side (3) facing away from the casting side (2), wherein at least one cooling channel (5) open towards the rear side (3) is located in the rear side (3), and comprising a cooling surface (9) which is opposite the casting side (3), wherein an insert (6) is located in the cooling channel (4, 5) in order to form a cooling gap (4) between an inner surface (7) of the insert (6) and the cooling surface (9). The insert (6) is connected to fastening points (15) in the cooling surface (9) by means of fastening bolts (17).

Description

technical field [0001] The invention relates to a metal formwork having the features of the preamble of claim 1 . Background technique [0002] Thermal stresses on the copper mold during continuous casting can lead to considerable material stresses within the copper alloy, especially in thin slab continuous casting plants. On its hot side facing the melt, ie the casting side, the metal form is subjected to extreme thermal stress, while the rear side facing the cooling water remains essentially cold. Within the metal formwork, which is only a few millimeters thick, there is a temperature gradient of several hundred Kelvin between the hot side and the water-cooled rear side. This results in a different thermal expansion in the thickness distribution from the casting side to the rear side. The casting side tries to expand, but at the same time is prevented from expanding by the rear side towards the cooling water. This results in high internal material stresses. When intern...
