摘要： A method for the production of cast steel strip in a continuous procedure includes casting a steel melt into a casting gap having longitudinal sides of which are formed by walls that move during the casting process, to form the steel strip, and holding the steel melt, which is present above the casting gap in a melt pool, under an atmosphere containing nitrogen and hydrogen. This method allows the production of high-quality steel strips having a significantly improved surface composition compared to the prior art in that the hydrogen content of the atmosphere is greater than 0 mol % to 10 mol %, and the Cr, Mo, Nb, Si, Ti, Ni, Mn, C or N contents of the cast steel melt, which are selectively present in each case for adjusting the characteristics of the steel strip, are in each case selected so that a ratio Creq/Nieq≧1.7.

摘要： A device and a method for casting of strips from a metal melt includes the use of two casting rollers, which delimit between them a casting gap at their longitudinal sides, and two side plates, which, arranged opposite one another, are held in contact at face sides of the casting rollers, allocated to narrow sides in each case of the casting gap. With the device and method, metallic strips can be reliably produced which have high dimensional stability even in the area of their strip edges, in that the risk of a gathering of solidified melt at the side plates in casting operation is reduced to a minimum. This is achieved by providing at least one heating device for the heating of the casting rollers in at least those sections of their face sides at which the side plate, allocated to the face side in each case, is in contact.

摘要： A method of making a cold strip with a ferritic structure includes casting a molten steel which forms a ferritic structure on cooling into a cast strip, wherein if necessary hot-rolling the cast strip in-line, coiling the hot-rolled strip and in one or more steps cold-rolling to form the cold strip. With such a method, cold strips can be produced, in which the risk of formation of an orange peel appearance or ridging is minimized during a cold forming process. The cast strip is cooled between the casting process and the coiling process from a starting temperature not lower than 1180° C., at a cooling rate of at least 150° C. per second, to a maximum intermediate temperature of 1000° C. and is then held for at least 10 seconds at a maintenance temperature of between 900 and 1000° C.
摘要翻译：制造具有铁素体结构的冷带的方法包括将冷却时形成铁素体结构的钢水浇铸成铸造带，其中如果必要的话，将铸造带一起热轧，将热轧钢带卷绕在一起或更多的步骤冷轧以形成冷带。通过这种方法，可以制造冷条，其中在冷成型过程中形成橙皮外观或皱纹的风险最小化。铸造钢带在铸造过程和卷取过程之间从不低于1180℃的起始温度以至少150℃/秒的冷却速率冷却至最大中间温度为1000℃，然后在900至1000℃的维持温度下保持至少10秒钟。

摘要： A casting roll for a two-roll casting device for the casting of metallic strip from a metal melt, in particular a steel melt, includes a roll body, on a casing surface of which a coating consisting of a coating material is applied by thermal spraying, which has a higher degree of hardness than the roll body. The casting roll according to the invention and the two-roll casting device, while easy to manufacture, has not only a long service life, but also allows for the manufacture of cast strips of optimum quality. This is achieved by the fact that the free surface of the coating, after thermal spraying, has a peak number RPc of at least 10 cm−1.
