Description
FILTRE POUR METAL LIQUIDE SERRAIX li1 invention a pour objet un filtre pour métal liquide comprenant une série d'au moins deux plaques en matière minérale, en contact les unes avec les autres et définissant entre elles une ou plusieurs cavités, ces plaques comportant chacune une série de trous permettant le passage et la filtration du métal liquide, ladite ou lesdites cavités contenant un ou plusieurs sachets fusibles ou pouvant se carboniser ou se calciner renfermant des produits destinés au traitement dudit métal. L'invention a également pour objet un procédé de mise en oeuvre du filtre selon l'invention. D'habitude, les agents de traitement sont tout simplement déposés dans les labyrinthes des filtres de ce type, ce qui est fastidieux.FILTER FOR LIQUID METAL SERRAIX The invention relates to a filter for liquid metal comprising a series of at least two plates of mineral material, in contact with one another and defining between them one or more cavities, these plates each comprising a series holes permitting the passage and filtration of the liquid metal, said cavity or cavities containing one or more sachets which can be fused or which can carbonize or calcine, containing products intended for the treatment of said metal. The invention also relates to a method of implementing the filter according to the invention. Usually, the processing agents are simply deposited in the labyrinths of filters of this type, which is tedious.
Il est aussi connu de prévoir la distribution des produits destinés au traitement dudit métal en interposant lesdits produits de traitement dans des sachets fusibles que l'on place dans un recoin du passage du métal se trouvant avant le filtre ,* ce procédé présente le désavantage de ne pas garantir que tout le métal entre en contact avec les agents de traitement.It is also known to provide for the distribution of products intended for the treatment of said metal by interposing said treatment products in fusible sachets which are placed in a recess of the passage of the metal located before the filter, * this process has the disadvantage of do not guarantee that all metal will come into contact with treatment agents.
Il est également connu de traiter le métal liquide en plaçant au-dessus du filtre des pastilles des produits de traitement agglomérés par collage ou par pression : là encore, on n'a pas la garantie que tout le métal a été traité. De plus, cela représente une manipulation supplémentaire.It is also known to treat liquid metal by placing agglomerated treatment products by gluing or pressing above the pellets: here again, there is no guarantee that all the metal has been treated. In addition, this represents additional manipulation.
Grâce au filtre, selon l'invention, comportant ledit ou lesdits sachets d'agent de traitement des métaux liquides, on est certain que tout le métal a été traité et que les agents de traitement ne laissent aucun résidu, et on facilite l'introduction du filtre dans son logement, ce qui est souvent exécuté automatiquement dans les fonderies modernes. L'objet de l'invention consiste en un filtre pour métal liquide comprenant une. série d'au moins deux plaques en matière minérale réfractaire, en contact les unes avec les autres et définissant entre elles une ou plusieurs cavités, ces plaques comportant chacune une série de trous permettant le passage et la filtration du métal liquide, caractérisé en ce que lesdites cavités contiennent un ou plusieurs sachets fusibles ou pouvant se carboniser ou se calciner renfermant des produits pulvérulents destinés au traitement dudit métal.Thanks to the filter according to the invention, comprising said bag or bags of liquid metal treatment agent, it is certain that all the metal has been treated and that the treatment agents leave no residue, and the introduction is facilitated of the filter in its housing, which is often performed automatically in modern foundries. The object of the invention consists of a filter for liquid metal comprising a. series of at least two plates of refractory mineral material, in contact with each other and defining between them one or more cavities, these plates each comprising a series of holes allowing the passage and filtration of the liquid metal, characterized in that said cavities contain one or more sachets which can be fused or which can carbonize or calcine, containing powdery products intended for the treatment of said metal.
Les produits de traitement contenus dans les sachets sont choisis parmi les produits désulfurants, thermogènes, inoculante, sphéroïdisante, reearburants et d'alliage d'addition.The treatment products contained in the sachets are chosen from desulfurizing, thermogenic, inoculating, spheroidizing, re-fuels and addition alloy products.
Le filtre selon l'invention .permet donc de filtrer et de traiter le métal par une seule opération.The filter according to the invention therefore enables the metal to be filtered and treated by a single operation.
Le procédé pour filtrer et traiter les métaux liquides est caractérisé en ce que le métal liquide passe à travers un filtre selon l'invention.The method for filtering and treating liquid metals is characterized in that the liquid metal passes through a filter according to the invention.
Un tel procédé permet d'obtenir un métal liquide possédant touts les propriétés désirées dès le début de la coulée. D'autres particularités et avantages apparaîtront encore dans la description ci-après.Such a process makes it possible to obtain a liquid metal having all the desired properties from the start of the casting. Other features and advantages will become apparent in the description below.
Aux dessins annexés i - la figure 1 est une vue en coupe d'un filtre objet de la présente invention è deux étages, - la figure 2 est une vue en plan d'un filtre objet de la présente invention, - la figure 3 est une vue en coupe d'un filtre ne comportant qu'une seule cavité. A la figure l, on distingue trois types différents de perforations 3, 3ft et 3b représentées sur le plateau supérieur 2 du filtre 1* , ces perforations peuvent présenter des ouvertures de quelque forme que ce soit, pourvu qu'elles soient constituées de passages étant inférieurs à la hauteur des espaces vides que fondent deux plateaux superposés.In the accompanying drawings i - Figure 1 is a sectional view of a filter object of the present invention on two stages, - Figure 2 is a plan view of a filter object of the present invention, - Figure 3 is a sectional view of a filter comprising only one cavity. In FIG. 1, there are three different types of perforations 3, 3ft and 3b represented on the upper plate 2 of the filter 1 *, these perforations may have openings of any shape whatsoever, provided that they consist of passages being lower than the height of the empty spaces that two superimposed trays found.
Dans cet exemple, le nombre d'espaces vides est limité à deux espaces 4 et 5, mais il peut en comporter un plus grand nombre.In this example, the number of empty spaces is limited to two spaces 4 and 5, but it can include a larger number.
Le filtre la comporte deux plateaux 2 et 2° munis sur l'une de leurs faces d'une bordure périphérique. Le plateau 2b n'en comporte pas, ce qui épaissirait inutilement l'ensemble.The filter la comprises two plates 2 and 2 ° provided on one of their faces with a peripheral border. The plate 2b does not have any, which would unnecessarily thicken the assembly.
La bordure périphérique formant un espace vide avec le plateau suivant peut, à l'aide de barrage, former au moins deux casiers, lesquels peuvent être garnis de sachets d'agents de traitement du métal liquide. Les plateaux peuvent présenter des orifices d'ouverture différents.The peripheral border forming an empty space with the next tray can, using a barrier, form at least two compartments, which can be filled with sachets of liquid metal treatment agents. The plates can have different opening orifices.
On distingue deux sachets 7 et 7B dont l'un est représenté comme ayant une importance moindre. Les sachets peuvent remplir partiellement ou presque complètement les cavités.There are two sachets 7 and 7B, one of which is shown to be of less importance. The sachets can partially or almost completely fill the cavities.
La figure 2 représente une vue en plan d'un filtre 1 tel que revendiqué qui ne présente qu'une seule bordure périphérique 2 en pointillés ne. délimitant qu'un seul espace vide. La figure 2 ne montre que des orifices 3 ayant des diamètres sensiblement égaux. Ceux-ci pourraient avoir une figure géométrique quelconque, le plateau 1 pourrait laisser deviner plusieurs compartiments.Figure 2 shows a plan view of a filter 1 as claimed which has only one peripheral border 2 dotted. delimiting only one empty space. FIG. 2 only shows orifices 3 having substantially equal diameters. These could have any geometric shape, the tray 1 could suggest several compartments.
La figure 3 présente un filtre lb constitué de deux éléments identiques 2a réunis tête-bêche par un collage en 10. Les bordures de ces éléments pourraient être de hauteurs différentes.FIG. 3 shows a filter 1b made up of two identical elements 2a joined head to tail by a glue at 10. The edges of these elements could be of different heights.
La position du sachet 7b est disposée dans l'espace vide 6 de manière excentrée, mais il peut occuper une place quelconque ou être en plusieurs parties.The position of the bag 7b is arranged in the empty space 6 eccentrically, but it can occupy any place or be in several parts.
Les sachets 7, 7n , 7b peuvent être réalisés à l'aide de feuilles d'aluminium, de papier ou en matière plastique .The bags 7, 7n, 7b can be produced using aluminum foil, paper or plastic.
Les grains de produits de traitement contenus dans les sachets peuvent être de dimensions différentes suivant que ceux-ci doivent par exemple fondre plus ou moins rapidement.The grains of treatment products contained in the sachets can be of different dimensions depending on whether the latter must for example melt more or less rapidly.
Le poids des sachets contenant les agents de traitement représentent environ 0,1% du poids du métal liquide à traiter.The weight of the sachets containing the treatment agents represent approximately 0.1% of the weight of the liquid metal to be treated.
Les produits de traitement peuvent permettre de remplir le rôle de désulfuration {par exemple à l'aide de magnésium et/ou de carbure de calcium) et/ou de jouer le rôle de produit thermogène (par exemple à l'aide de carbure de calcium) et/ou de servir de pré-inoculation et/ou d'inoculation et/ou de post-inoculation (par exemple à base de silicium, de calcium, de zirconium, de carbone, de baryum) et/ou de sphéroïdisation (par exemple du magnésium, des ferrosilicomagnésiums) et/ou d'alliages d'addition (par exemple à l'aide d'alliages au molybdène, au bore, au silicium, au ferrosilicium, au manganèse, au chrome, au titane, au silicomischmétal, au ferro-aluminium, etc.) ; il faut également inclure la possibilité de recarburation (par exemple à l'aide de carbone, de graphite, etc.).The treatment products can make it possible to fulfill the role of desulfurization (for example using magnesium and / or calcium carbide) and / or to play the role of thermogenic product (for example using calcium carbide ) and / or serve as pre-inoculation and / or inoculation and / or post-inoculation (for example based on silicon, calcium, zirconium, carbon, barium) and / or spheroidization (by example of magnesium, ferrosilicomagnesiums) and / or addition alloys (for example using alloys of molybdenum, boron, silicon, ferrosilicon, manganese, chromium, titanium, silicomischmetal, ferro-aluminum, etc.); it must also include the possibility of recarburization (for example using carbon, graphite, etc.).
Le procédé permettant de filtrer et de traiter simultanément le métal liquide consiste à faire passer le métal liquide à travers un filtre 1, 1B, lb.The method for simultaneously filtering and treating the liquid metal consists in passing the liquid metal through a filter 1, 1B, lb.
