  • Patent number: 7658807
    Abstract: The present invention relates to a hot-rolled steel strip for further processing to form non-grain oriented electrical sheet with the following composition (in % by weight) C: <0.02%, Mn: ?1.2%, Si: 0.1-4.4%, Al 0.1-4.4%, wherein the sum formed from the Si content and twice the Al content is <5%, P: <0.15%, Sn: ?0.20%, Sb: ?0.20%, the remainder iron and unavoidable impurities, with a strip thickness which is at most 1.8 mm, and with a partially softened structure which is characterised by a high intensity for the ? fibre (fibre representation of orientation distribution functions) in the region of 0° to 60°, wherein the ratio I112/I001 formed from the intensity I112 of the position (112) <110> to the intensity I001 of the position (001) <110> is >0.4 and the ratio I111/I001 formed from the intensity I111 of the position (111) <110> to the intensity I001 of the position (001) <110> is >0.2.

  • Patent number: 6835253
    Abstract: The invention relates to a method for producing a hot strip, in particular for producing a hot strip intended for the production of a cold strip with good deep-drawing characteristics; in which a steel melt comprising (in % by weight) C:≦0.07%, Si:≦0.5%, Mn:≦2.5%, Al:≦0.1%, N:≦0.01%, P:≦0.025, B:≦0.05, if need be up to a total of 0.

  • Patent number: 5958312
    Abstract: It was difficult until now to carry out intermediate repairs of monolithic refractory lining walls of steel casting and handling ladles when the slag area of the lining was worn before other areas. According to this new process for reconstructing the refractory lining in the upper area of the wall, repairs may be economically carried out in that the gap between the lower end of the template and the lining that projects under the area to be reconstructed is sealed by inflating a hose-like sealing body and by deflating again the sealing body before removing the template. This process is useful for steel casting and handling ladles and for similar metallurgical vessels.
