摘要： The invention relates to a method for producing a metal strip by continuously casting a molten bath between two casting cylinders (1, 2) of a continuous casting machine. According to said method, a surface current of the inclusions or impurities present on top of the bath is generated by injecting gas into the surface of the molten bath (4a). The injection of gas transports those inclusions or impurities laterally against the lateral seals (3). For this purpose, a device (25) is provided that has at least one gas channel (35, 36; 52) disposed above the surface of the molten bath (4a) and extending in the longitudinal direction of the casting cylinders (1, 2). Said channel has a number of outlet openings (46; 55) that are distributed across its entire length and that are directed downward at an angle and towards the next lateral seal (3). Said device makes it possible to keep the impurities from at least a larger part of the cast strip, thereby increasing purity of the strip.

摘要： The present invention relates to a tool for use with molten metal, to an assembly of such a tool with a handle and to a method for the attachment of such a tool to a handle.
the invention provides a tool for use with molten metal comprising a bowl portion (1) made from a refractory material and defining an inner region (2) and an outer region (3) and means for connecting the bowl portion to a handle. According to the invention, the connecting means are located in the outer region (3). Therefore, contrarily to the conventional assemblies (figures 1 and 2), which have connecting means (8,9) located in the inner region (2) of the bowl portion, there is no bore (11) ending into the inner region of the bowl portion. The problems relating to cement patching for the threaded bolt are eliminated and the likelihood of the connecting means entering into contact with the molten metal are largely reduced.

摘要： The invention relates to a method for producing a cast metal strip using a twin roll casting installation. Said casting installation comprises two casting rolls and two lateral plates that together define a molten metal chamber and a casting gap. Molten metal is introduced in to the molten metal chamber and forms in said molten metal chamber a molten metal bath with a bath surface that is open to the top. A cast metal strip is conveyed from the molten metal chamber and through the casting gap. A delimiting surface area (30) for collecting particles that are foreign to the molten metal is produced on the surface of the bath under the effect of at least one gas jet (20, 20a, 20b). The aim of the invention is to substantially avoid the introduction of particles that are foreign to the molten metal into the surface or into the near-surface zone of the cast strip. For this purpose, the at least one gas jet (20, 20a, 20b) is directed together with the casting roll (1, 2) onto the bath surface at a distance of the gas jet axis (21) to the contact line (10, 11) of the bath surface (8).
