Description

DescriptionDescription

La présente invention concerne un support pour une sonde de haut fourneau qui est introduite horizontalement à travers une ouverture prévue dans la paroi latérale du haut fourneau, cette paroi latérale étant constituée d'un blindage métallique et d'un revêtement intérieur en matière réfractaire comprenant un bloc fixé sur une bride prévue à cet effet sur le blindage métallique, ce bloc étant pourvu d'un alésage axial pour permettre le passage de la sonde.The present invention relates to a support for a blast furnace probe which is introduced horizontally through an opening provided in the side wall of the blast furnace, this side wall consisting of a metal shield and an inner lining of refractory material comprising a block fixed on a flange provided for this purpose on the metal shielding, this block being provided with an axial bore to allow the passage of the probe.

Ces sondes sont destinées à mesurer la température à différents points prédéterminés à l'inte- rieur du four et à prélever des échantillons gazeux pour les analyser. Le résultat de ces mesures et analyses permet la surveillance et le contrôle de la marche du four.These probes are intended to measure the temperature at various predetermined points inside the oven and to take gas samples for analysis. The result of these measurements and analyzes allows monitoring and control of the operation of the oven.

Il existe deux types différents de telles sondes. Les unes sont disposées au-dessus de la matière de chargement et y demeurent en permanence. Les autres sont introduites dans la matière de chargement même et sont à nouveau extraites après le prélèvement des échantillons. Une sonde de ce genre est décrite dans le brevet DE 15 33 829.There are two different types of such probes. Some are arranged above the loading material and remain there permanently. The others are introduced into the loading material itself and are extracted again after the samples have been taken. A probe of this kind is described in patent DE 15 33 829.

Afin du pouvoir fournir des renseignements aussi complets et précis que possibles, ces sondes doivent pénétrer jusque dans la région de l'axe central du four. Par conséquent, suivant la capacité du four, ces sondes doivent avoir jusqu'à huit mètres de longueur et parfois même plus. Il en résulte de sérieux problèmes de support qui deviennent d'autant plus difficiles que les sondes sont plus longues. En effet, ces sondes se trouvent en porte-à-faux avec comme seul point d'appui une bride prévue sur la blindage métallique de la paroi du four pour l'introduction de ces sondes. Celles-ci sont par conséquent exposées à des risques de déformations sous l'action de leur propre poids et sous l'action de la descente de la matière à l'intérieur du four. En outre, le point de support de la sonde subit la réaction de ces efforts et sollications, réaction proportionnelle aux moments exercés par la longueur de porte-à-faux de la sonde. Cette réaction est maximale lorsque la sonde est complètement enfoncée et la force de frottement qui en résulte au niveau du support s'oppose au glissement de la sonde. L'effort nécessaire au déplacement de la sonde en subit les conséquences néfastes. Jusqu'à présent, il n'était pas possible de surmonter ces difficultés, car la nécessité d'effectueur des mesures et analyses dans la région de l'axe du four interdit une diminution de la longueur de la sonde, même en sachant que la déformation à l'extrémité intérieure est proportionnelle à la troisième puissance de la longueur de porte-à-faux, comme le prouvent les lois de la mécanique statique.In order to be able to provide as complete and precise information as possible, these probes must penetrate into the region of the central axis of the furnace. Therefore, depending on the capacity of the oven, these probes must be up to eight meters in length and sometimes even more. This results in serious support problems which become all the more difficult as the probes are longer. Indeed, these probes are cantilevered with the only support point a flange provided on the metal shielding of the wall of the oven for the introduction of these probes. These are therefore exposed to the risk of deformation under the action of their own weight and under the action of the descent of the material inside the oven. In addition, the support point of the probe undergoes the reaction of these forces and requests, reaction proportional to the moments exerted by the length of the probe overhang. This reaction is maximum when the probe is fully inserted and the resulting frictional force on the support opposes the sliding of the probe. The effort required to move the probe is adversely affected. Until now, it has not been possible to overcome these difficulties, because the need for measurements and analyzes in the region of the axis of the oven prevents a reduction in the length of the probe, even knowing that the Deformation at the inner end is proportional to the third power of the length of the overhang, as evidenced by the laws of static mechanics.

Le but de la présente invention est de prévoir un support pour une sonde qui permet de réduire les inconvénients et problèmes causés par la suspension en porte-à-faux de la sonde.The object of the present invention is to provide a support for a probe which makes it possible to reduce the drawbacks and problems caused by the cantilevered suspension of the probe.

Pour atteindre cet objectif, la présente invention présente un support pour une sonde du type décrit ci-dessus, qui présente les caractéristiques de la revendication 1.To achieve this objective, the present invention presents a support for a probe of the type described above, which has the features of claim 1.

La présente invention propose une sonde dont l'appui est décalé vers l'intérieur du four, en comparaison avec l'appui des sondes existantes, ce qui permet de réduire de cette manière la longueur de porte-à-faux. L'invention permet ainsi de gagner environ 80-100 cm, ce qui, compte tenu du fait que la longueur de porte-à-faux intervient à la troisième puissance pour la détermination des déformations, constitue un progrès non négligeable. Ainsi par exemple, la flèche résultant du poids propre de la sonde, se réduit pour une diminution de 5 à 4 mètres du porte-à-faux, àThe present invention provides a probe whose support is offset towards the interior of the furnace, in comparison with the support of existing probes, which makes it possible to reduce in this way the length of the overhang. The invention thus makes it possible to gain approximately 80-100 cm, which, taking into account the fact that the length of overhang intervenes at the third power for the determination of the deformations, constitutes a non-negligible progress. Thus, for example, the deflection resulting from the self-weight of the probe is reduced for a reduction of 5 to 4 meters from the overhang, to

Figure imgb0001

soit 40% de la flèche d'un porte-à-faux de 5 m.i.e. 40% of the deflection of a 5 m overhang.

L'appui inférieur de la sonde est de préférence en forme d'auge dont la courbure correspond à celle de l'alésage du bloc de support.The lower support of the probe is preferably in the form of a trough whose curvature corresponds to that of the bore of the support block.

D'autres particularités et caractéristiques ressortiront de la description détaillée d'un mode de réalisation avantageux présente ci-dessous, à titre d'illustration, en référence aux dessins, dans lesquels:

  • La figure 1 représente schématiquement une coupe longitudinale à travers une sonde enposi- tion opérative et
  • La figure 2 montre schématiquement les détails du support de sonde montré.à la figure 1.
Other particularities and characteristics will emerge from the detailed description of an advantageous embodiment presented below, by way of illustration, with reference to the drawings, in which:
  • FIG. 1 schematically represents a longitudinal section through a probe in operative position and
  • Figure 2 schematically shows the details of the probe holder shown in Figure 1.

La figure 1 montre schématiquement une sonde 10 en position de mesure introduite dans la matière de chargement d'un fourneau dont la paroi est constituée par un blindage métallique extérieur 12 et un revêtement réfractaire intérieur 14. Cette sonde 10 est introduite à travers une ouverture 18 prévue dans le blindage 12 et la revêtement réfractaire 14. Le blindage 12 est pourvu d'une bride 20 autour de cette ouverture 18 pour la fixation d'un support 22 selon la présente invention. Sur le support 22 se trouve, du côté extérieur, une vanne 16 connue en soi, destinée à fermer l'ouverture délaissée après l'extraction de la sonde 10 hors du four.FIG. 1 schematically shows a probe 10 in the measurement position introduced into the loading material of a furnace, the wall of which is constituted by an external metal shield 12 and an interior refractory lining 14. This probe 10 is introduced through an opening 18 provided in the shield 12 and the refractory lining 14. The shield 12 is provided with a flange 20 around this opening 18 for fixing a support 22 according to the present invention. On the support 22 is located, on the outside, a valve 16 known per se, intended to close the opening abandoned after the extraction of the probe 10 from the oven.

Le support 22 proposé par l'invention comporte essentiellement un bloc 24 occupant l'espace délimité par la bridge 20 du blindage 12, et un appui 26 s'étendant dans l'ouverture 18 au moins qu'au-delà de la moitié de l'épaisseur du revêtement réfractaire 14. Le bloc 22 est fixé, de manière connue en soi, par exemple au moyen de boulons non représentés sur la bride 20.The support 22 proposed by the invention essentially comprises a block 24 occupying the space delimited by the bridge 20 of the shielding 12, and a support 26 extending in the opening 18 at least than beyond half of the thickness of the refractory lining 14. The block 22 is fixed, in a manner known per se, for example by means of bolts not shown on the flange 20.

Le bloc 24 comporte un alésage central 30 dont le diamètre est légèrement supérieur à celui de la sonde 10 pour permettre le passage de celle-ci. Cet alésage 30 est prolongé, en partie, par l'appui 26 dont la face supérieure est en forme d'auge, avec une corbure correspondant à celle de l'alésage 30. Sur l'extrémité intérieure de l'appui 26 est prévu un rechargement 28 en acier dur et réfractaire sur lequel repose et glisse la sonde 10. Le rechargement 28 formé par cette soudure constitue le seul appui inférieur de la sonde 10 et détermine la longeur "L" de porte-à-faux de la sonde. Du côté extérieur à une distance "I" du rechargement 28 se trouve un second appui 32 qui est un appui supérieur.The block 24 has a central bore 30 whose diameter is slightly greater than that of the probe 10 to allow passage of the latter. This bore 30 is extended, in part, by the support 26, the upper face of which is in the shape of a trough, with a curvature corresponding to that of the bore 30. On the inner end of the support 26 is provided a reloading 28 in hard and refractory steel on which the probe 10 slides and slides. The recharging 28 formed by this weld constitutes the only lower support of the probe 10 and determines the length "L" of the probe overhang. On the outside at a distance "I" from the reloading 28 is a second support 32 which is an upper support.

Le support 22 proposé par l'invention a permis d'augmenter la longueur "I" au profit de la longueur "L" et en modifiant le rapport "%", l'invention permet une diminution sensible des réactions aux deux points d'appui 28 et 32.The support 22 proposed by the invention has made it possible to increase the length "I" in favor of the length "L" and by modifying the ratio "%", the invention allows a significant reduction in the reactions at the two support points 28 and 32.

Comme montré sur la figure 2, le support 22 est pourvu d'une entrée 34 et d'un sortie 36 pour la circulation d'un liquide de refroidissement. A cet effet, le corps du bloc 24 et de l'appui 26 sont creux et le liquide de refroidissement est amené directement de l'entrée 34 jusqu'à l'extrémité intérieure de l'appui 26 d'où il retourne dans le creux du bloc 24 pour sortir par l'orifice 36.As shown in Figure 2, the support 22 is provided with an inlet 34 and an outlet 36 for the circulation of a coolant. For this purpose, the body of the block 24 and of the support 26 are hollow and the coolant is brought directly from the inlet 34 to the inner end of the support 26 from which it returns to the hollow from block 24 to exit through orifice 36.

Pour éviter les dépôts de poussières et saleté dans l'alésage 30 et sur l'appui 26, il est également prévu un système d'injection d'un fluide de rinçage, par exemple de l'air sous pression. A cet effet, le support 22 comporte un orifice d'admission 38 conçu pour être branché sur une conduite d'air sous pression non montrée et débouchant dans une chambre circulaire 40 communiquant par une fente circulaire 42 avec l'alésage 30.To avoid deposits of dust and dirt in the bore 30 and on the support 26, there is also provided a system for injecting a rinsing fluid, for example pressurized air. To this end, the support 22 comprises an inlet orifice 38 designed to be connected to a pressure air line not shown and opening into a circular chamber 40 communicating by a circular slot 42 with the bore 30.

Il est évident que le support proposé par l'invention est aussi bien adaptable aux sondes se trouvant au-dessus du lit de fusion qu'à celles conçues pour être introduites dans la matière de chargement.It is obvious that the support proposed by the invention is as well adaptable to the probes located above the fusion bed as to those designed to be introduced into the loading material.
