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. The metal strip is then stored for a short time in a strip accumulator, and is then taken up and conveyed by means of a second drive roll stand that operates at a second transport speed. In a final step, the metal strip is coiled up to a bundle under pretension.

Abstract: A blowing lance to be used for the treatment of metallurgical melts includes a lance head having several expansion tuyeres directed to the bath level of the melt and penetrating a front plate of the lance head. They depart from at least one lance channel, which is peripherally surrounded by a supply channel and a return channel for a cooling medium. The supply channel is separated from the return channel by a flow deflection piece arranged above the front plate and penetrated by at least one connecting channel connecting the supply and return channels and provided for the cooling medium. In order to considerably increase the service life of the blowing lance and to avoid leakages in the front plate, at least one coolant secondary channel is provided in addition to the at least one connecting channel, which, upon branching off a partial stream of the coolant flowing to the connecting channel, diverts this partial stream into a flow direction deviating from the flow direction in the connecting channel and whose mouth is directed directly towards the center of the front plate.
