摘要： The invention relates to a method for hot-dip coating a metal strip (1), particularly a steel strip, in which the metal strip (1) is fed to a receptacle (5) accommodating the melted coating metal (4) through a hole (6) in the bottom area of the receptacle (5) after passing through a furnace (2) and a roll chamber (3) that adjoins the furnace (2) in the direction of travel (F) of the metal strip (1). An electromagnetic field is generated in the bottom area of the receptacle (5) so as to retain the coating metal (4) in the receptacle (5). In order to obtain more advantageous operating conditions especially in case the performance of the hot-dip coating system drops, different gas atmospheres are maintained in at least two separate spaces (7, 8) of the roll chamber (3). The invention further relates to a hot-dip coating device.

摘要： A method and an apparatus for an anticipatory thickness control in foil rolling by using characteristic lines stored in a process control computer of the individual manipulated variables (for example, strip tensions, rolling speeds) for various operating points (conditions of operation) or by using an on-line operating physical computing model, also in combination with a monitor control. The method includes the steps of determining the thickness deviations of the foil at the entry side of the roll stand and of compensating the thickness deviations by an anticipatory thickness control. The apparatus includes a thickness measuring device between the running-off reel and the rolling mill or the roll gap of the roll stand. The thickness measuring device is connected to a superordinated process control computer. Following the thickness measuring device is arranged a tensioning unit which serves to change the travel path of the foil strip between the running-off reel and the roll gap. For example, the tensioning unit elongates the travel path.

摘要： A method of coiling or placing bar steel or wire in coils, wherein the rolling stock is reeled from rolling heat in a basket or is placed by a coiler in the form of coils onto a conveyor and is collected at the end of the conveyor over a mandrel into a coil, wherein the rolling stock is cooled during coiling and the rolling stock is further cooled after the coiling process or the formation of coils. Cooling of the rolling stock from rolling heat prior to coiling into the transformation range characterized by the Ar.sub.3 line or Ar.sub.1 line of the transformation time-temperature diagram corresponding to the type of steel to be cooled is extended, such that, depending on the type of steel, the rolling stock is transformed immediately after cooling prior to, during or after coiling, uniformly over the entire length and entire cross-section thereof essentially isothermally from the austenite phase into the ferrite phase or pearlite phase and, as required, into the bainite phase.
