Definitions
- the present invention relates to a metal alloy for use at a very high temperature, particularly used in a process for manufacturing mineral wool by fiberizing a molten mineral composition, or more generally for the constitution of tools having high temperature strength. in an oxidizing medium such as molten glass, and cobalt-based alloys that can be used at high temperature, in particular for the production of articles for producing and / or heat-transforming glass or other mineral material, such as of mineral wool making machinery.
- a fiber drawing technique consists in continuously dropping liquid glass inside a set of revolution parts rotating at a very high speed of rotation about their vertical axis.
- a centerpiece called “plate”, more often referred to in the art as the “spinner”, receives the glass against a so-called “band” wall pierced with holes, which the glass passes under the effect of centrifugal force for to escape from all parts in the form of melted filaments.
- An annular burner located above the outside of the plate, producing a downward gas flow along the outer wall of the strip, deflects these filaments downwardly by stretching them. These then “solidify” in the form of glass wool.
- the plate is a fiber-drawing tool that is very thermally stressed (thermal shocks during start-ups and shutdowns, and establishment in stabilized use of a temperature gradient along the part), mechanically (centrifugal force, erosion due to the passage of the glass) and chemically (oxidation and corrosion by the molten glass, and by the hot gases coming out of the burner around the plate). Its main modes of deterioration are: the deformation by hot creep of the vertical walls, the appearance of horizontal or vertical cracks, erosion wear of the fiberization holes, which require the pure and simple replacement of the organs. Their constituent material must therefore withstand during a production time long enough to remain compatible with the technical and economic constraints of the process.
- materials with a certain ductility, creep resistance and resistance to corrosion and / or oxidation are sought.
- Various known materials for the realization of these tools are superalloys based on nickel or cobalt reinforced by precipitation of carbides.
- Particularly refractory alloys are based on chromium, cobalt (refractory element which brings to the matrix of the alloy an intrinsic strength at high temperature improved) and nickel (to stabilize the face-centered cubic crystal lattice of the Co).
- WO-A-99/16919 discloses a cobalt-based alloy having improved mechanical properties at high temperature, comprising the following elements (in percentage by weight of the alloy):
- the molar ratio of tantalum to carbon being of the order of 0.4 to 1.
- the selection of carbon and tantalum proportions is intended forming in the alloy a dense but discontinuous network of intergranular carbides consisting essentially of chromium carbides in Cr 7 C 3 and (Cr, W) 2 3C 6 form and by tantalum carbides TaC. This selection gives the alloy improved mechanical and oxidation resistance properties at high temperatures, allowing the drawing of a molten glass whose temperature is 1080 ° C.
- cobalt-based alloys likely to be used at even higher temperatures. These alloys have a good compromise between mechanical strength and resistance to oxidation from 1100 ° C through a microstructure whose intergranular zones are rich in tantalum carbide precipitates. These carbides play on the one hand the role of a mechanical reinforcement by opposing intergranular creep at very high temperature, and on the other hand have an effect on the oxidation resistance related to their oxidation in Ta 2 O 5 , which forms oxides occupying all the old volume of TaC carbides preventing the penetration of the aggressive medium (liquid glass, hot gases) in intergranular spaces.
- the aggressive medium liquid glass, hot gases
- a fibering plate made from the alloy described in Example 6 of WO 2005/052208 can withstand, for relatively long periods, temperatures of the molten glass of the order of 1200 to 1240 ° C., corresponding to a metal temperature of between 1160 and 1210 ° C, depending on the profile of the plate.
- the present invention aims at providing still improved alloys whose high temperature mechanical resistance is increased, making it possible to work at a temperature (for the metal) of up to 1200 ° C., or even at higher temperatures, and having a duration improved life under such fiber drawing conditions.
- the subject of the present invention is a cobalt-based alloy, further comprising chromium, and carbon, which contains the following elements (the proportions being indicated in percentage by weight of the alloy):
- the alloy according to the present invention differs from the alloys incorporating Ti and Ta carbides described in the application WO 2005/052208 (see in particular Examples 6 and 7), in that the nickel content is substantially lower than those described in this publication (8.7% weight for the alloys of Examples 6 and 7).
- the presence of such a quantity of nickel was necessary to extend the temperature stability domain of the face-centered cubic crystal structure of the cobalt matrix (see for example page 7 lines 18-21 of WO2005 / 052208 or page 8 lines 29-32 and page
- the properties of the alloy compositions according to the present invention appeared to be greater than those of the previously described alloys.
- the lifetimes of the plates obtained from the alloys according to the invention during a high temperature fiber drawing process appeared very substantially improved.
- Carbon is an essential constituent of the alloy, necessary for the formation of metal carbide precipitates.
- the carbon content directly determines the amount of carbides present in the alloy. It is at least 0.2% by weight to obtain the minimum reinforcement desired, preferably at least 0.6% by weight, but preferably limited to at most 1, 2% by weight to prevent the alloy from becoming hard and difficult to machine because of too high density of reinforcements.
- the lack of ductility of the alloy at such levels prevents it from accommodating without breaking an imposed deformation (for example of thermal origin) and withstanding sufficiently the propagation of cracks.
- chromium contributes to the intrinsic mechanical strength of the matrix in which it is present partly in solid solution, and in some cases also in the form of carbides essentially of Cr 2 3C 6 type in fine dispersion inside. grains where they provide resistance to intragranular creep or in the form of Cr 7 C 3 or Cr 23 C 6 type carbides present at the grain boundaries, which prevent grain-grain slippage thus also contributing to the intergranular reinforcement of the alloy.
- Chromium contributes to the corrosion resistance as a chromium oxide precursor forming a protective layer on the surface exposed to the oxidizing medium. A minimal amount of chromium is required for the formation and maintenance of this protective layer. Too high a chromium content, however, is detrimental to strength and toughness at elevated temperatures, as it leads to too high rigidity and too low stress elongation that is incompatible with high temperature stresses.
- the chromium content of an alloy which can be used according to the invention is 23 to 34% by weight, preferably of the order of 26 to 32% by weight, advantageously of approximately 27 to 30% by weight. .
- the nickel, present in the alloy in the form of a solid solution with cobalt, is present in an amount of less than 5% by weight of the alloy.
- the amount of nickel present in the alloy is less than 4%, or even less than 3% or even less than 2% by weight of the alloy.
- the threshold at which the Ni is present only in the form of unavoidable impurities, excellent life values of plates, not yet observed so far, have also been obtained.
- unavoidable impurities is meant within the meaning of the present invention that the nickel is not present intentionally in the composition of the alloy but that it is introduced in the form of impurities contained in at least one of the main elements of the alloy (or in at least one of the precursors of said main elements).
- nickel was almost always present in the form of unavoidable impurities of at least 0.3% by weight and most often at least 0.5% by weight. or at least 0.7% by weight.
- percentages of nickel in the alloy less than 0.3% by weight must also be considered as part of the invention, but the cost generated by such purity would then make the cost of the alloy too expensive to allow the commercial viability of the fiber drawing process.
- Titanium is a more common element and less expensive than tantalum, so it penalizes less the final cost of the alloy.
- the fact that this element is light can also be an advantage.
- a minimum amount of titanium of 0.2 to 5% by weight of the alloy appeared preferable to produce a sufficient amount of TiC carbides, certainly due to the solubility of titanium in the cobalt cfc matrix.
- a titanium content of the order of 0.5 to 4% seems advantageous, especially 0.6 to 3%. Excellent results have been obtained for alloys comprising Ti contents between 0.8 and 2%.
- the alloys according to the invention comprising mixed carbides of tantalum and titanium demonstrate a still improved high temperature stability, as will be described later.
- the tantalum present in the alloy is partly in solid solution in the cobalt matrix of which this heavy atom locally distorts the crystal lattice and hinders or even blocks the progression of the dislocations when the material is subjected to mechanical stress, thus contributing to the intrinsic strength of the matrix.
- the minimum content of tantalum for the formation of mixed carbides with the Ti according to the invention is of the order of 0.5%, preferably of the order of 1% and very preferably of the order of 1, 5% or even 2%.
- the upper limit of the tantalum content can be chosen to be about 7%.
- the tantalum content is preferably of the order of 2 to 6%, in particular of 1 to 5%.
- the tantalum content is very preferably less than 5%, even 4.5% or even 4% and advantageously close to 3.
- a small amount of tantalum has the double advantage of substantially reducing the overall cost of the alloy but also to allow easy machining of said alloy. The higher the content of tantalum, the harder the alloy is, that is to say difficult to form.
- the alloy may contain other elements in minority proportions or in the form of unavoidable impurities. It generally includes:
- silicon as deoxidizer of the molten metal during the preparation and molding of the alloy, in a proportion of less than 1% by weight;
- manganese also deoxidizing, in a proportion of less than 0.5% by weight
- the cumulative amount of the other elements introduced as impurities with the essential constituents of the alloy advantageously represents less than 1% by weight of the composition of the alloy.
- the alloys according to the invention are preferably free of Ce, La, B, Y, Dy, Re and other rare earths.
- the alloys that can be used according to the invention which contain highly reactive elements, can be shaped by casting, in particular by inductive melting in at least partially inert atmosphere and casting in a sand mold.
- the casting may optionally be followed by a heat treatment at a temperature that may go beyond the fiberizing temperature.
- the invention also relates to a method of manufacturing an article by casting from the alloys described above as an object of the invention.
- the process may comprise at least one cooling stage, after casting and / or after or during a heat treatment, for example by cooling in air, in particular with a return to ambient temperature.
- the alloys that are the subject of the invention can be used to manufacture all kinds of parts mechanically stressed at high temperature and / or made to work in an oxidizing or corrosive medium.
- the invention also relates to such articles made from an alloy according to the invention, in particular by foundry. Among such applications include the manufacture of articles used for the development or hot processing of glass, for example fiber plates for the manufacture of mineral wool.
- the subject of the invention is also a process for the manufacture of mineral wool by internal centrifugation, in which a flow of molten mineral matter is poured into a fiber-drawing plate whose peripheral band is pierced with a multitude of orifices through which filaments of molten mineral material escape, which are then drawn into wool by the action of a gas, the temperature of the mineral material in the plate being at least 1200 ° C. and the fibering plate being made of an alloy as defined above.
- the alloys according to the invention thus make it possible to fiber glass or a similar molten mineral composition having a liquidus temperature T
- the fibering of these molten mineral compositions can be carried out in a temperature range (for the melt composition arriving in the plate) between T hq and T
- these compositions of mineral material it may be preferred compositions containing a significant amount of iron, which are less corrosive vis-à-vis the constituent metal of the fiberizing members.
- the process according to the invention advantageously uses a composition of oxidizing mineral material, in particular with respect to chromium, capable of repairing or reconstituting the protective layer of Cr 2 O 3 oxide which is established on the surface.
- compositions containing iron essentially in ferric form may be preferred, in particular with a molar ratio of the degrees FeO oxidation II and III, expressed by the ratio of the order of 0.1 to 0.3,
- FeO + Fe 2 O 3 in particular 0.15 to 0.20.
- the mineral material composition contains a high iron content allowing rapid kinetics of reconstitution of chromium oxide with a level of iron oxide (so-called "total iron” rate, corresponding to the total content of iron expressed conventionally in the form of Fe 2 O 3 equivalent) of at least 3%, preferably at least 4%, in particular of the order of 4 to 12%, in particular of at least 5%.
- total iron a level of iron oxide
- this corresponds to a ferric iron content Fe 2 O 3 alone of at least 2.7%, preferably at least 3.6%
- compositions are known in particular from WO-99/56525 and advantageously comprise the following constituents:
- RO (CaO + MgO) 9-26%, preferably 12-25%
- MgO 4-20% preferably 7-16%
- compositions known from WO-00/171 17 are particularly suitable for the process according to the invention.
- MgO being between 0 and 5%, especially between 0 and 2% when R 2 O ⁇ 13.0%.
- the compositions have iron oxide levels of between 5 and 12%, especially between 5 and 8%, which can make it possible to obtain a fire resistance of the mineral wool mattresses.
- the invention can be applied to the manufacture of very diverse articles, when they must have a high mechanical strength in an oxidizing and / or corrosive medium, particularly at high temperature.
- these alloys can be used to make any type of refractory alloy fixed or moving parts for operating or operating a high temperature heat treatment furnace (beyond
- a heat exchanger or a reactor in the chemical industry can thus be for example hot fan blades, cooking support, charging material, etc. They can also be used to produce any type of heating resistor intended to operate in a hot oxidizing atmosphere, and to realize Turbine components, used in land, sea or air vehicle engines or in any other application that does not target vehicles, eg power plants.
- the invention thus relates to the use in an oxidizing atmosphere at a temperature of at least 1200 ° C of an article consisting of an alloy as defined above.
- a molten charge is prepared for the following composition which is then formed by simply casting into a mold of sand:
- the casting is followed by a heat treatment comprising a solution phase for 2 hours at 1200 ° C. and a secondary carbide precipitation phase for 10 hours at 1000 ° C., each of these stages ending with air cooling. to room temperature.
- a second fibering plate 400 mm in diameter and having the same characteristics is prepared from a melted filler of the following composition: Cr 28.84%
- the capacity of the plates thus formed was evaluated in the fiberglass fiber application. More specifically the plates were placed on a industrial fiber drawing line of a basaltic glass composition:
- the plates are used with two different shots of 10 and 12,5 tons per day until their decision is decided following the ruin of the plate, declared by a visible deterioration or by a quality of fiber produced become insufficiently good .
- the temperature of the mineral composition arriving in the plate is of the order of 1200 to 1240 ° C.
- the temperature of the metal according to the profile of the plate is between 1160 and 1210 ° C.
- Table 1 The results of the lifetimes of the plates, according to their conditions of use, are reported in Table 1. In this table, for the sake of clarity and to facilitate an immediate comparison, the values of the lifetimes obtained for Plates according to the invention (Examples 1 and 2) were matched with the values obtained for the reference plates (Example 3), for identical conditions of the course.
- the solidus temperature of the alloy constituting the plates is then measured according to conventional differential thermal analysis (DTA) techniques, after their use in the preceding fiberizing process.
- DTA differential thermal analysis
- solidus temperature is meant in the sense of the present description, the melting temperature of alloys in equilibrium. Due to a different method of analysis, it should be noted that the values obtained from the solidus temperatures reported in Table 2 differ somewhat from the values previously obtained in WO 2005/052208. However, the relative differences in melting temperature between the alloys according to the invention and the reference alloy remain identical, whatever the method used.
- the solidus temperature of the alloys according to the invention is about 10 ° C higher than the alloys of the prior art in all cases, which reflects a greater refractoriness. Because of the relative proximity between the operating temperature of the plate in the fiberizing process and the melting temperature of the constituent alloy of the plate, such an improvement is extremely significant and could justify on its own the superior properties. of high temperature strength, as observed on the present alloys.
- Example 1 The high temperature strength properties of the alloys of Example 1 according to the invention and of Example 3 according to the prior art were evaluated in tests of resistance to three-point bending at 1250 ° C. load of 31 MPa for a period of 200 hours. The tests were carried out for each alloy on a series of parallelepipedic specimens of 30 mm wide and 3 mm thick, the load being exerted in the middle of a center distance of 37 mm. The results are shown in Table 3. Table 3 shows the slope of the three-point creep curves obtained for each alloy, said slope illustrating the rate of deformation (in ⁇ m.h "1 ) of the specimen by creep.
- Table 3 summarizes all the results obtained, giving for each alloy the average creep rates, as well as the maximum and minimum values observed over the entire set of test pieces.
