Description

  

  Récipient en acier inoxydable avec fond renforcé et procédé  pour obtenir ledit récipient.         L'invention    a pour     ,objet    un récipient en  acier inoxydable avec fond renforcé en autre  métal et un procédé pour obtenir ledit réci  pient.  



  Le dessin     ci-joint    en montre, à titre       d'exemple,    une forme     d'exécution.     



  La     fig.    1 est une coupe diamétrale sui  vant     A-A    de la     fig.    2, mais tandis que la       fig.    1 représente le récipient     terminé,    la       fig.    2 le montre avant qu'il soit muni du  fond de     renforcement.     



  Le fond plan extérieur la du récipient en  acier     inoxydable    1 est soudé au rebord inté  rieur 2a d'une couronne 2 en acier ordinaire  dont le rebord     extérieur    2b est à une petite  distance du fond la. Le fond de renforce  ment 3, est en un alliage     d'aluminium    par  exemple, qui a     été    coulé par les moyens con  nus et     entoure    la couronne 2. comme le montre  la     fig.    1, de manière à maintenir le fond de  renforcement 3 appliqué contre     7.e    fond la.  



  En pratique, le rebord     2.a    est soudé au  fond la par une soudure continue pour qu'il    n'y ait pas des     points:    de soudure distants  les     uns    des autres, et afin     d'éviter    ainsi des       interstices    dans lesquels de l'humidité ou des  liquides pourraient     s'étendme    entre les     fonds     la et 3.    L'armature pourrait comprendre, en plus  de la couronne 2, d'autres éléments, par       exemple        Vélément    d'armature semi-rigide en  <B>S</B> dont il est question dans le brevet  no 211632.  



  La forme de l'armature constituée par la  couronne 2 pourrait être modifiée pourvu  que sa section radiale présente une partie  soudée au fond 1a et     un    bec     s'écartant    de       ce    fond, afin que, lors de la coulée du fond  3, la masse métallique de celui-ci passe     au-          dessus    et au-dessous dudit bec et     recouvre     et entoure en outre complètement la cou  ronne. L'armature pourrait comporter plu  sieurs couronnes concentriques, chacune  d'elles pouvant être constituée par des por  tions de couronne se touchant ou non.



  Stainless steel container with reinforced bottom and method for obtaining said container. The invention relates to a stainless steel container with a reinforced bottom made of another metal and a process for obtaining said container.



  The accompanying drawing shows, by way of example, one embodiment.



  Fig. 1 is a diametral section following A-A of FIG. 2, but while FIG. 1 shows the finished container, FIG. 2 shows it before it is provided with the reinforcement bottom.



  The outer flat bottom 1a of the stainless steel container 1 is welded to the inner rim 2a of a ring 2 of ordinary steel, the outer rim 2b of which is at a small distance from the bottom 1a. The reinforcing base 3 is made of an aluminum alloy, for example, which has been cast by known means and surrounds the ring 2. as shown in FIG. 1, so as to keep the reinforcement base 3 applied against the bottom of the 7.th.



  In practice, the flange 2.a is welded to the bottom 1a by a continuous weld so that there are no welding points distant from each other, and thus to avoid interstices in which the moisture or liquids could spread between the bottoms 1a and 3. The reinforcement could include, in addition to the crown 2, other elements, for example semi-rigid reinforcement element in <B> S </ B > referred to in patent No. 211632.



  The shape of the reinforcement constituted by the crown 2 could be modified provided that its radial section has a part welded to the base 1a and a spout moving away from this base, so that, during the casting of the base 3, the metal mass thereof passes above and below said beak and further covers and completely surrounds the crown. The framework could include several concentric crowns, each of them being able to be constituted by crown portions touching or not.

Claims

R.EVENI) ÏCATÏOE i: Stainless steel container with reinforced bottom of other metal, characterized in that the reinforcing bottom cast against the outer flat stainless steel bottom is kept pressed against the latter by a frame comprising at least one crown metal, the radial section of which has a part welded to the outer flat bottom made of stainless steel and a spout moving away from this bottom, and in that the metal mass of the reinforcing base completely covers and surrounds the frame. SUBCLAIMS: 1.

Container according to claim, ia- actéris6 in that the metal crown consists of several portions which do not touch each other. \ ?. A container according to claim, characterized in that the crown has an inner rim welded to the stainless steel bottom, and an outer rim located at a small distance therefrom. 3. A container according to claim, as shown in the accompanying drawing. 4. Container according to claim, ca ractérisé in that the reinforcing bottom c @ t in an aluminum alloy.

CLAIM II: A method for obtaining the container according to claim I, characterized in that an ordinary steel ring being firstly fixed to the stainless steel base by means of a continuous weld, it is poured on this steel base, the reinforcement bottom.
