  • Patent number: 8069904
    Abstract: In a method for producing hot strips from a deformable lightweight steel which includes as main elements Fe, Mn, Si and Al, melt is cast close to its final dimension in a horizontal continuous strip casting installation under a protective gas to form a pre-strip between 6 and 20 mm, and the temperature of the pre-strip is adjusted after complete solidification and before the beginning of a hot-rolling process. The pre-strip is passed through a device under a protective gas for homogenization in concert with a selective maintenance of the temperature, cooling or heating, and subsequently subjected to a hot-rolling process having at least one pass with a total degree of deformation of at least 50%, and is then reeled as a hot strip following the cooling process. The hot-rolling process is executed in-line or in decoupled manner depending on the ratio of casting speed to rolling speed.

  • Patent number: 8047263
    Abstract: The invention relates to a device for the horizontal continuous strip casting of steel, especially steel with high manganese content, for producing a pre-strip with a thickness ?15 mm. The device includes a tundish containing the melt, a primary cooling zone having two deflection pulleys and a revolving cooled conveyor belt, and a secondary cooling zone which follows the primary cooling zone and has a housed roller table. A guide element having at least one roller is hereby arranged at the end of the primary cooling zone and before the start of the secondary cooling zone.

  • Publication number: 20100059196
    Abstract: The invention relates to a method for producing hot strips (18) from a deformable lightweight steel which is especially suitable for cold deep drawing and includes as main elements Fe, Mn, Si and Al, and which has a high tensile strength and TRIP and/or TWIP properties. Melt is cast close to its final dimension in a horizontal continuous strip casting installation (1) under a protective gas in order to form a pre-strip between 6 and 20 mm, and the temperature of the pre-strip is adjusted after complete solidification and before the beginning of a hot-rolling process. According to the invention, the pre-strip is passed through a device (10) under a protective gas for homogenization in concert with a selective maintenance of the temperature, cooling or heating, and subsequently subjected to a hot-rolling process having at least one pass with a total degree of deformation of at least 50%, and is then reeled as a hot strip following the cooling process.
