Description
<Desc/Clms Page number 1>
La présente invention se rapporte à un procédé de coulée qontinue des métaux en lingotière sans fond et généralement refroidie à l'eau,faci- litant le démoulage ou extraction de la billette ou autre produit obtenu.
La présente invention consiste à vibrer la lingotière; pareille vibration de faible amplitude et de fréquence variable peut être réalisée par un des différents moyens connus et utilisés dans la technique, tel que: systèmes pneumatique, système mécanique, système électro-magnétique,magnéto-
EMI1.1
striction, par piezo-électricitéy etc...
Outre la diminution de la friction entre billette et lingotière a laquelle correspond une plus grande facilité d'extraction ou de démoulage continus, le procédé qui consiste à vibrer la lingotière améliore également la qualité de la billette ou autre produit coulé, cette amélioration de la qualité résulte; 1 ) de l'amélioration de l'état de surface.
2 ) de;la cristallisation primaire plus fine et moins orientée,et 3 ) de la diminution de la porosité.
Ces trois effets sont la conséquence directe de la vibration transmise par la coquille à la billette en cours de solidification.
REVENDICATIONS .
1. Procédé de coulée continue des métaux en lingotière sans fond refroidie, caractérisé en ce qu'au cours de la coulée et de l'extrac- tion corrélative du produit obtenu,on soumet la lingotière à des vibra- tions.

<Desc / Clms Page number 1>
The present invention relates to a process for the continuous casting of metals in a bottomless and generally water-cooled ingot mold, facilitating the demolding or extraction of the billet or other product obtained.
The present invention consists in vibrating the mold; such a vibration of low amplitude and of variable frequency can be achieved by one of the various means known and used in the art, such as: pneumatic systems, mechanical system, electromagnetic system, magneto
EMI1.1
necking, by piezoelectricity, etc ...
In addition to the reduction in the friction between billet and ingot mold to which corresponds greater ease of continuous extraction or demoulding, the process which consists in vibrating the ingot mold also improves the quality of the billet or other cast product, this improvement in quality. results; 1) improvement of the surface condition.
2) finer and less oriented primary crystallization, and 3) decrease in porosity.
These three effects are the direct consequence of the vibration transmitted by the shell to the billet during solidification.
CLAIMS.
1. Process for the continuous casting of metals in a cooled bottomless ingot mold, characterized in that during the casting and the correlative extraction of the product obtained, the ingot mold is subjected to vibrations.
** ATTENTION ** end of DESC field can contain start of CLMS **.
