Title: A ladle, a ladle heating system and methods of heating the ladle
Inventor: NOMURA HIROSHI
IPC: B22D41/015
Filed: 2000-08-23
Granted: 2009-01-27
Abstract: A ladle after teeming for a continuous casting and a subsequent slag discharge is mounted on a ladle truck and then moved by the ladle truck to a tapping station. The ladle on the ladle truck is then stationed over a predetermined stand-by time and is then immediately moved to a tapping position to receive a molten steel from a converter. The ladle is quickly heated during the stand-by time, by a regenerative-type burner system carried by a ladle lid which is attached to the ladle to cover the top opening of the ladle. This allows the tapping temperature of the molten steel to be set to a low level, offering advantages such as a remarkable reduction in the consumption of carbonaceous materials as the temperature controller, as well as extended life of ladle refractories through suppression of thermal attack. At the same time, consumption of fuel gas for heating the ladle by the burner system is reduced to contribute to saving of energy.

Abstract: L'invention concerne un procédé et un appareil permettant de transférer un fluide à un champ stérile, le procédé de cette invention consistant notamment à utiliser une enveloppe stérile (58, 68) abritant une seringue (40). Cette enveloppe (58, 68), constituée de deux parties, permet à cette seringue (40) de pouvoir fonctionner tout en restant à l'intérieur de ladite enveloppe. Lorsque l'on souhaite transférer des fluides au champ stérile, l'enveloppe est séparée en deux parties au moins, de manière à pouvoir retirer ladite seringue. Ce retrait de la seringue s'effectue de sorte que l'utilisateur se trouvant dans le champ stérile ne touche pas cette seringue, ce qui permet à celle-ci et au fluide qu'elle contient d'être facilement transférés audit champ stérile.

Granted: 2010-08-03
Abstract: Ethylbenzene is produced by alkylation over monoclinic silicalite catalysts having a weak acid site concentration of less than 50 micromoles per gram. A feedstock containing benzene and ethylene is applied to an alkylation reaction zone having at least one catalyst bed containing a monoclinic silicalite catalyst having a weak acid site concentration of less than 50 micromoles per gram. The alkylation reaction zone is operated at temperature and pressure conditions in which the benzene is in a gaseous phase to cause gas- phase alkylation of the aromatic substrate in the presence of the silicalite catalysts to produce an alkylation product. The alkylation product is then withdrawn from the reaction zone for separation and recovery.
