摘要： Molten metal pouring procedure uses metal plates fixed to refractory inner surface of distributor before or after preheating. The procedure, for use with a continuous metal pouring installation that has an inner coating of a refractory material, consists of fastening metal plates with a composition corresponding to that of the poured metal to the surface of the refractory material. The fastening is carried out, e.g. by nailing or stapling, with at least some plates fitted prior to preheating the distributor, and the remainder after preheating, with a final preheating by induction.

摘要： Casting roller comprises a metallic rolling body (2) having a metallic layer (4) which is harder than the material of the rolling body. The layer has a lower hardness in a region bordering the rolling body than in the region of its free surface. An Independent claim is also included for a process for producing the casting roller comprising electrolytically depositing a metallic layer on the rolling body using a deposition stream which increases from a lowest possible value during the course of the deposition process. Preferred Features: The layer in the region bordering the rolling body has a different composition than in the region of its free surface.

摘要： Producing a cold rolled strip with a ferritic structure by casting a steel melt into a strip, optionally hot rolling the strip, coiling the hot rolled strip and subjecting it to one or more cold rolling operations comprises cooling the cast strip from an initial temperature (T1) of at least 1180[deg]C at a rate of at least 150[deg]C/second to an intermediate temperature (T2) of up to 1000[deg]C and then keeping it at a temperature (T3) of 900-1000[deg]C for at least 10 seconds.

摘要： Die vorliegende Erfindung betrifft ein Produkt für strömungstechnische Anwendungen, mit mindestens einem Oberflächenabschnitt A, der dazu vorgesehen ist, mit einem in eine Strömungsrichtung S strömenden Fluid in Kontakt zu kommen, wobei in dem mit dem Fluid in Kontakt kommenden Abschnitt A Rippen 1, 1', 1'' bestimmter Länge L1, L2 und Form ausgebildet sind, von denen benachbarte Rippen 1, 1', 1'' zwischen sich jeweils ein Tal 8, 8' begrenzen, sowie ein Verfahren zur Herstellung und eine Verwendung eines solchen Produkts. Das erfindungsgemäße Produkt lässt sich wirtschaftlich mit weiter verbesserten Strömungseigenschaften herstellen. Dies wird dadurch erreicht, dass jeweils mindestens zwei Rippen 1, 1', 1'' mit dem von ihnen jeweils begrenzten Tal 8, 8' zu einer Gruppe G, G' zusammengefasst sind, dass mindestens zwei Gruppen G, G' vorhanden sind, dass jede Gruppe G, G' von jeder quer zur Strömungsrichtung S des Fluids betrachtet benachbart zu ihr angeordneten Gruppe G, G' durch ein Tal 8, 8' getrennt ist und dass sich das Höhenprofil des die jeweiligen Gruppen G, G' voneinander trennenden Tals 12, 12' jeweils vom Höhenprofil der Täler unterscheidet, die durch diejenigen Rippen 1, 1', 1'' der Gruppen G, G' begrenzt sind, die gleichzeitig an das die Gruppen G, G' voneinander trennende Tal 12, 12' grenzen.

摘要： A twin roll caster and a method for operating comprising two casting rolls that delimit a casting gap on its longitudinal sides; two side plates that delimit the casting gap on its narrow sides; and at least one axial actuator associated with one of the side plates and impacting the respective side plate on its rear turned away from the front sides of the casting rolls with a force axially aligned toward the casting gap pressing the side plate against the front sides of the casting rolls. An axial actuator acts on the rear side of the side plate by means of a joint provided to adjust an angular offset between the normal level relative to the effective direction of the force applied by the axial actuator to the side plate and the normal level relative to the axes of rotation of the casting rolls.

摘要： A method for operating a two-roll casting machine for casting molten metal into cast strip, which machine has two casting rolls which are each rotatively driven in opposite directions about an axis of rotation and between them delimit a casting gap on its longitudinal sides, with side plates that can be placed on the casting rolls, which side plates seal the casting gap on its narrow sides in the casting operation, bridging the casting gap with a refractory material, wherein the side plates are moved during the casting operation in a direction which is aligned parallel to the direction of conveying in which the cast strip leaves the casting gap. With such a method the formation of grooves distorting the casting result and the casting operation can be suppressed with increased certainty and the service life of the side plates can be increased, compared to the prior art.
