- EP 0 397 952 B1 describes a process for continuous heating Dip coating of stainless steel strip with aluminum is known, in which the strip is in an argon purged housing on a series of magnetic current devices is led past the tape by an argon plasma discharge while at the same time Heating to the temperature desired for the dip coating is cleaned and that cleaned tape is immersed in a bath of molten aluminum.
- DE 195 45 259 A1 describes a method and a device for generating known from thin metal strands, in which a metal strip through a vertical Steel melt is guided and a layer thickness of 20-2% the starting metal band is crystallized. Depending on the thickness, the metal band is on a Temperature between room temperature and a maximum of 900 ° C preheated. With this Processes are made of composite sheets in which one of the materials used is a stainless steel, an austenitic or ferritic steel.
- the invention has set itself the goal of a method and a device and a To create a product with which, with simple means, an intimate, error-free connection of the individual layers of different materials Composite is achievable.
- the invention achieves this goal in that the carrier tape is preheated on its surface before being passed through the molten coating material and is pretreated in such a way that chemical elements are added or incorporated in such a way that while passing through the support material between the pretreated surface of the carrier tape and the shell crystallizing on the surface of the carrier tape, a binding area is formed from a gradient material by diffusion processes, the liquidus temperature of which is at least in parts of this bonding area below the liquidus temperature of the carrier tape and the pad material.
- the temperature can not be chosen so high that the carrier tape in Melting pool is melted or loses its strength to such an extent that during the Transportes tears off. It was surprisingly found that the core of the Carrier tape can be kept at a reasonable temperature while for that desired intimate connection, the liquidus temperature at least on the belt surface can be lowered in order thus to diffusion-borne mixing in the liquid enable.
- various means are shown in the invention that support diffusion-borne alloy formation in the binding area.
- This means can already be given to the carrier tape, but they can also be supportive or can be applied from the outside alone to the tape by the carrier tape according to the invention for the preparation of its surface is passed through a medium which the corresponding chemical at least partially penetrating into the surface Contains items.
- the medium can be a gas such as nitrogen, Hydrogen, carbon monoxide, ammonia or carbon dioxide or any other Feature of the invention a liquid such as sulfuric acid, liquid ammonia or be liquid nitrogen. It is also possible that the medium is a solid such as a Is cyan salt, carbonate or blood lye salt.
- the carrier tape is made of steel, which in the area of its surface a carbon content> 20 ppm or one Has nitrogen content> 20 ppm.
- the transport speed of the carrier belt and / or is advantageously its immersion depth or immersion length in the liquid support material in one set in such a way that a minimum diving time of 50 msec is observed, the total diving time is limited by the desired one Layer thickness and the risk of melting of the Carrier tape.
- the surface of the carrier tape be immersed in the to roughen liquid coating material.
- the carrier tape is a carbon-containing steel which is preheated at least on its surface to a temperature of T before > 900 ° C.
- the support material is at best a high-alloy steel, in particular a chrome-alloy steel.

- Preheating device for the carrier tape wherein according to the invention Preheater in an inlet area in front of the metallurgical vessel arranged, the carrier tape enclosing housing is arranged in the over at least one feed led into the housing by one Media supply coming medium can be introduced.
- the shape of the vessel through which the carrier tape is guided can be chosen as desired become. Plunge pools with deflection rollers or containers are used here a bottom passage for the carrier tape, the latter being the carrier tape is guided vertically through the casting tank.
- the latter have containers so far the advantage that the parameters immersion length and Belt speed depending on the belt temperature can be maintained can, because the bath height in the vessel is particularly simple and operational can be adjusted.
- the carrier tape immediately into the non-oxidizing environment Melting bath introduced. This can be done by an enclosure that is partially in the melt protrudes or, in the case of a vessel with a bottom opening, by a direct Attachment below the bottom of the vessel.
- gaseous media such as Nitrogen, hydrogen, carbon monoxide or carbon dioxide onto the surface of the Carrier tape are given are either blowing nozzles at the feed provided through which the gaseous medium enters the interior of the enclosure and / or is inflatable on the surface of the carrier tape, or it will be on the Supply spray nozzles are provided through which the liquid medium, e.g. Sulfuric acid, liquid ammonia or liquid nitrogen on the surface of the carrier tape is sprayable.
- the liquid medium e.g. Sulfuric acid, liquid ammonia or liquid nitrogen on the surface of the carrier tape is sprayable.
- solids or free-flowing materials can also be used to lower the Liquidus temperature of the carrier tape can be used, such as cyan salt, carbonate or Potassium ferrocyanide.
- free-flowing materials these are over Feeder introduced and in contact with the surface of the carrier tape brought, the tape entrains the solid as it passes the channels.
- the medium can also be designed as a reloadable solid and be pressed against the surface of the carrier tape.
- the solids will shaped as a block, for example, which is under adequate pressure against the surface of the Carrier tape is pressed.
- measuring elements for detecting the Melt temperature, the temperature and the speed of the carrier tape used the at least one actuator for setting the Control the speed of the carrier belt.
- bath height is recorded and also the computer for processing provided.
- a very precise and safe bath height adjustment is e.g. through a Vacuum container realizable.
- the carrier tape can in particular by influencing the content of Alloy elements such as C or other alloy elements at grain boundaries such as N, be set so that there are local liquidus temperature drops the consequence that the bonding layer has a tooth-like connecting line.

dadurch gekennzeichnet, dass das metallurgische Gefäß (11) durch eine Haube (63) abgedeckt ist, die mit einer Gasversorgung (58) zur Versorgung mit Inertgas, in Verbindung steht, und die das beschichtete Trägerband umhüllt, bis dessen Oberfläche durcherstarrt ist - Einrichtung nach einem der Ansprüche 12 bis 16,
dadurch gekennzeichnet, dass dem metallurgischen Gefäß (11) in Abzugsrichtung des Trägerbandes (22) mindestens ein Walzgerüst (33) nachgeordnet ist. - Metallband aus Verbundwerkstoff, von dem mindestens ein Werkstoff aus nicht rostendem Stahl ist, wobei auf das durch ein Auftragsmaterial geführtes Trägerband eine deutlich dünnere Schicht aufkristallisiert wird, hergestellt nach dem Verfahren entsprechend Anspruch 1 und mit einer Vorrichtung entsprechend Anspruch 12,
dadurch gekennzeichnet, dass die Beschichtung auf mindestens einer Seite des Trägerbandes eine Dicke (dA) von dA = 0,01 bis 0,3 x D
mit D = Dicke des als Mutterstrang eingesetzten Trägerbandes besitzt,
dass zwischen der Beschichtung und dem Trägerband eine Bindeschicht vorhanden ist, die eine Dicke von (dB) von dB = 5 bis 150 µm besitzt,
dass die Bindeschicht eine Verzahnungslinie aufweist, die die dem Trägerband wie auch der Beschichtung zuzuordnende Bindeschicht zusätzlich formschlüssig verbindet, und
