  • Patent number: 6907915
    Abstract: The invention relates to a method and to an installation for producing a metal strip. The aim of the invention is to make sure that the metal strip formed in the casting installation passes through the first cooling and grain texturing phase substantially without being subjected to stress and without effects on the subsequent installations. To this end, the molten bath is fed to a two-roll casting device and a cast metal strip is formed in the casting gap between two casting rolls whose rotational axes lie in a horizontal plane (two-roll casting method), the thickness of the cast strip ranging between 1.0 to 20 mm, preferably between 1.5 to 12 mm. The cast metal strip that freely emerges downwards from the two-roll casting installation is directly deflected from the vertical casting direction to a substantially horizontal transport direction. The metal strip is taken up and conveyed in a controlled manner by means of a first drive roll stand that operates at a first transport speed.

  • Patent number: 5697241
    Abstract: There is disclosed a rolling arrangement including a rolling stand and a preceding descaling means. In order to obtain a perfect surface quality while maintaining a high energy content of the rolling stock the descaling means is arranged immediately in front of the rolls of the rolling stand and is formed by a rotor descaling means. The liquid jets emerging from the rotor descaling means and impinging on the rolling stock are directed opposite to the rolling direction. The liquid impinging on the point of impact of the liquid jet on the surface of the rolling stock, after impingement has a flow resultant which--projected on the rolling direction--has a component opposite to the rolling direction.
