FLUID-COOLED MOLD BACKGROUND OF THE INVENTION The invention pertains to a fluid-cooled mold which is particularly suitable for electroslag remelting installations wherein molten metal, for example steel, is stored in the casting space. The inner wall space of the mold is lined with plates.
The larger fluid-cooled molds in the installations for the manufacture of cast ingots (respectively strands) having rectangular, square or polygonal cross sections have, generally, plates lining the inner wall surfaces of the molds and these plates are generally connected to each other by means of screwed connections. The hot metal causes (particularly in those areas of the wall lining which absorb inpacts) thermal stresses during the cooling of the hot molten metal, for example molten steel, which effects the formation of gaps through which the hot molten metal or slag may leak out.
It is therefore a general object of this invention to provide a mold construction wherein the aforedescribed drawback is eliminated.
It is a more specific object of this invention to provide an inner lining for a mold in electroslag remelting installations wherein the plates lining the inner wall surface of the mold are connected in such a way that the connections are impact-resistant and no gaps are formed despite the influence of hot molten metal and slag on the plates.
A mold construction of the aforedescribed type is obtained by providing an intermediate member between adjacent plates which have edge portions that overlap the surfaces of the plates facing the casting space, and said intermediate members extend longitudinally relative to the mold.
The present invention will be better understood upon consideration of the following description and examination of the annexed drawing which show a non-limiting preferred embodiment of a mold construction in accordance with the present invention.
IN THE DRAWING The FIGURE illustrates a cross-sectional partial schematic view of the mold wall construction for electroslag-remelting of steels.
The mold construction of the invention includes a cylindrical mold wall 1 having stiffening ribs 1' welded to the outer periphery of the mold wall I. On the inner side of the mold wall 1 there are disposed eight identical plates 2 having mating curved convex surfaces. These plates 2 are preferably made out of copper. The plates 2 are secured to the wall I by non-illustrated screws or bolts.
Intermediate members 3 are disposed between adjacent plates 2. Each intermediate member 3 has a substantially key-shaped cross section. Each intermediate member 3 is provided with a leg 4 which extends between adjacent plates 2, and a flange 5 which bears against the adjacent inner wall surfaces 2' of the plates 2. Thus the marginal edge portions 2" of the plates 2 are covered by the flange 5 which extends longitudinally relative to the mold (that is perpendicularly to the plane of the FIGURE. The width b of the leg 4 of the intermediate member 3 is smaller than the minimum distance a between adjacent plates 2. The surface of the intermediate member 3 facing the casting space 10 is convexly curved. The angle a between the surface 3' facing the casting space 10 of the intermediate member 3 and the adjacent surface 2" of the plate 2 is at least 30 and preferably 45 to Each intermediate member 3 is secured to the wall 1 by means of a bolt 6 having a hexagonal head 7 which can be screwed into the leg 4 of the intermediate member 3. Two dishshaped springs 8 are disposed between the 7 and the wall 1 on each bolt 6. Each intermediate member 3 has a channel 9 and each plate 2 is provided with a plurality of channels 9 all of which have circular cross sections and which extend preferably longitudinally relative to the mold to conduct a cooling medium, for example water, therethrough. The casting space 10 has therefore generally an octagonal shape.
However, other shaped casting spaces can be similarly constructed, for example casting spaces having substantially square or rectangular cross sections can similarly be constructed in accordance with the invention.
Furthermore, the plates lining the inner wall of the mold may have surfaces facing the casting space which can be non-planar, for example convexly curved.
The mold construction of this invention is suitable not only for electroslag-remelting installations but for example also for continuous casting installations.
Although the invention is illustrated and described with reference to one preferred embodiment thereof, it is to he expressly understood that it is in no way limited to the disclosure of such a preferred embodiment, but is capable of numerous modifications within the scope of the appended claims.
I claim:
1. In a fluid-cooled mold for receiving electroslag remelted molten metal and defining a casting space,
a plurality of plates covering at least a part of the interior of the mold and having edge portions extending longitudinally relative to the mold which define gaps between adjacent plates; and
a plurality of substantially T-shaped members disposed intermediate each pair of the plates and each having a leg and a flange, the leg of each member extending into the gap between the associated plates, the flange of each member covering the edge portions of the associated plates which confront said casting space, the width of each leg being smaller than the minimum width of the gap between the associated plates.
2. The fluid-cooled mold as set forth in claim l, wherein each intermediate member is connected to the mold by means of at least one bolt threadably mounted on said leg and extending through the mold; said bolt extending perpendicularly relative to said flange of said intermediate member.
3. The fluid-cooled mold as set forth in claim 2, and dish-shaped spring means disposed between said bolt and said mold.
4. The fluid-cooled mold as set forth in claim I, wherein the surface of said intermediate member confronting said casting space is convexly curved.
5. The fluid-celled mold as set forth in claim 4, wherein the angle between said surface of said intermediate member confronting the casting space and the adjacent edge portion of a plate ls 45 to 90.
