JUL-10-01 04:35PM FROM-SCOTT & AYLEN IP CA 02351081 2001-05-11 *613-230-8841 T-595 P.03/12 F-167 Tra.nslated Text of WO 00/29146 (PCT/EP99/08442) with Amended Pages and Clal>las Incorporated Therei.n Mold Plate of a Continuous Caszing PlanG
The present invention relates zo a mold plate of copper for a continuous casting plant, comprisirlg a working surface facing a metal melt or a (partially) solidified metal strand during operation of the continuous casting plant and comprising at leasc one cooling surface contaczing a cooling medium during operation of the conLinuous casting plant, wherein the mold place has a heat conductivity and extends along a mold length in the casting direction.
Such a mold plate is k.nown, for example, from EP 0 149 734 A1.
The mold plat.es have in their upper area a reduced heat conductivity and a greater thermal resistance chan in the lower area.
When caszing metal, in particular, steel, by continuous casting, a high wear occurs on zhe mold places. Accordingly, the working surface of zhe mold plate must be refinished from time to time after a number of ladles which number depends on the conditions of use of the mold plate. When doing so, the thickness of the mold plate continuously decreases.
In order to cast high-quality steel strands, the t.emperaLure of the working surface must be within a predetermined range.
Moreover, the thickness of the mold plate must be within a JUL-10-01 04:35PM FROM-SCOTT & AYLEN IP CA 02351081 2001-05-11,613-230-8842 T-permissible thickness range which is greater than the minimum thickness required for mechanical reasons.
The application of layers, in particular, of nickel layers, onto mold plates as such is already known. For example, reference is being had to WO 97/12708 and Herrmann, "Handbook on Concinuous Casting", Aluminium-Verlag, Dusseldorf, 1980. zn the prior art, a nickel layer is however applied to the working surface of zhe mold plate. It serves primarily for reducing the mold wear during continuous casting.
It is an objecz of the presenz invention co develop a mold place of che aforemenLioned kind such that it can be refinished more often than was possible in the past when a minimally permissible copper wall thickness has already been reached.
This object is solved in chac onco zhe cooling surface at least in one portion thereof a layer with a heat conductivity is applied and in that the layer heat conductivity of the layer is smaller than the heat conductivity of the mold plate, that che layer is substantially comprised of nickel, and that the layer is a layer that is applied currencless onto the cooling surface in a nickel bath.
It is particularly advantageous when the layer is comprised substantially of nickel because the thermal expansion coefficient of nickel is smaller than the thermal expansion coefficient of a conventional mold plate of copper. The nickel layer is preferably deposized currenciess onco the cooling surface of the mold plate in a nickel bath with additives. This is so because in this situation, concour-sharp coazings of the cooling surface are possible. Moreover, the layer thickness is very uniform and the heat conductivity of the layer is considerably smaller than that of nickel applied by electroplating. Independent of the coating process, the layer heat conductivity should be maximally 10 % of the heat conductivity of the copper of the mold plate.
The insulating properties of the layer are even better when the layer is comprised of five to twenty percent of phosphorus and otherwise - aside from contaminants - of nickel. This is so because in this case, the layer heat conductivity is less than 3 % of the heat conductivity of the mold plate made of copper.
The cooling surface can be formed as a cooling groove arranged on a back side that is located opposite the working surface or a cooling bore closed relative to the back side that is located opposite the working surface.
The cooling groove has a bottom surface and sidewalls. The layer can be applied only onto the bottom surface and/or also onto the sidewalls, as desired.
When the layer extends from an upper edge, viewed in the casting direction, across a layer length and the layer length is smaller than the mold length, the temperature distribution across the mold length can be influenced. The layer length is at least 100 mm, preferably between 300 mm and 500 mm.
Alternatively, the layer can also extend over the entire mold length.
In one aspect, the present invention provides a mold plate of copper of a continuous casting plant, comprising a working surface facing during operation of the continuous casting plant a metal melt or a (partially) solidified metal strand and at least one cooling surface contacting during operation of the continuous casting plant a cooling medium, wherein the mold plate has a heat conductivity and extends in a casting direction across a mold length, wherein on the cooling surface, at least on one portion, a layer with a layer heat conductivity is applied and in that the heat conductivity of the layer is smaller than the heat conductivity of the mold plate, in that the layer is substantially comprised of nickel, and in that the layer is a layer applied currentless onto the cooling surface in a nickel bath.
Further advantages and details result from the following description of an embodiment in connection with the drawings.

Fig_ 3 a coating method; and Fig. 4 a further detail of the mold plate with cooling bores.
According to Fig. 1, a continuous casting plant has mold places 1 made of copper. Each mold plate 1 has a working surface 2 which extends in the casting direction x across a mold length L.
During operazion of the conLinuous casting plant, a metal melt 3, in general, a steel melc, is located between the working surfaces 2. The metal melt 3 solidifies gradually to a meral scrand 4 which is removed in the casting direction x from the mold plates 1.
For a controlled solidificazion of the mezal melt 3 to a metal strand 4, a considerable energy quantity, che so-called casting heat, must be removed via the mold plates 1. For the purpose of removing the casting heac, the mold places 1 have according to Fig. 2 cooling surfaces 5 which contact a cooling medium, for example, water (not illustrated) during operation of the continuous casting mold. The cooling surfaces 5 are arranged on the backside 6 which is positioned opposite the working surface 2. They are open toward the backside 6. They are moreover formed as cooling grooves 5.
As already menzioned, the mold plate 1 is comprised of copper.
Ic has therefore a high heat conductivity W of, for example, approximately 377 W/mK. In order to impart to the mold plate 1 a greater thermal resistance, or a reduced total heat conductivity, a layer 7 is applied onto che cooling surfaces S. This layer 7 JUL-10-01 04:36PM FROM-SCOTT & AYLEN IP CA 02351081 2001 05 11*613-230-8842 T-595 P.07/12 F-167 has a heat conductivity S which is considerably smaller than the heat conductivity W of the copper plate.
According to the embodiment, the layer 7 is comprised substanzially of nickel, having a phosphorus conzents of 5$ to 20 t. Preferably, the phosphorus contents is between 9t and 14 a, for example, 10 $ to 12 t. The heat conductivity of the layer can be further reduced in that, in addition to zhe phosphorus added to the nickel bath, also up to 30 t silicon carbide is added. Otherwise, the layer 7 contains only minimal conzaminants.
Preferably, the layer 7, as illustrated schematically in Pig_ 3, is applied in that the mold plate 1 is introduced into a nickel bath 8. Here, the layer 7 is applied currentless onto the cooling surfaces 5. Such a nickel layer 7 has a layer heat conductivity S which is, for example, approximacely only 5 W/mK.
The layer 7 has a layer thickness d which is, of course, dependent on the residence cime of the mold plare 1 in the nickel bath 8. By means of conventional nickel baths 8 layer thicknesses d chac are between 40 pm and 80 m, for example, 60 m, can be applied to the coating surfaces 5. In a special nickel bath 8 it is however also possible to apply a layer 7 having a layer thickness d of up to 200 m_ In principle, it is also possible to coat the backside 6 completely. Technically, this is the simplest approach.
However, ic is also possible to provide the backside 6, before it is being coated with a layer 7, with a protective layer and to apply che nickel layer 7 only onto the porcions that are not covered.

However, it is also possible to apply che layer 7 onto the bottom surfaces 9 and the sidewalls 10. Finally, it is also possible to apply the layer 7 over the entire surface area, i.e., onto che bottom surfaces 9 and the sidewalls 10 of the cooling grooves 5 as well as onco che intermediacely positioned stays 11. According to Fig. 2, the cwo lefc cooling grooves 5 are completely coated while only the bottom surfaces 9 of the cwo right cooling grooves 5 are coated.
It is furthermore possible that the layer 7 extends over che encire mold length L. This is the case for the oucer cooling channels in Fig. 2. Alternatively, the layer 7 can extend from the upper edge 12 only across a layer length 1 when viewed in the casting direction x, wherein the lengch 1 is smaller than the mold length L. The layer length 1 is preferably between 300 mm and 500 mm, at least however 100 mm. This is the case for the inner cooling channels in Fig. 2.
The mold plate 1 according to Fig. 4 differs from the mold place 1 according to Fig. 2 in thac, instead of the cooling grooves 5 which are open toward the backside 6, cooling bores 5' are provided. In this case, the cooling bores 5' are also provided with the iayer 7 wherein, as before, alternatively a complete or only a partial coating over the length of the cooling bores 5' is possible.
