|20130183542||PROCESS FOR PRODUCING AN IRON-TIN LAYER ON A PACKAGING STEEL SUBSTRATE - A production process for producing an iron-tin alloy layer on a packaging steel substrate and to a substrate provided with said layer wherein one or both sides of a SR- or DR-blackplate substrate is coated with an iron-tin alloy layer which contains at least 80 weight percent (wt. %) of FeSn (50 at. % tin and 50 at. % iron).||07-18-2013|
|20130153094||METHOD FOR HOT FORMING A COATED METAL PART AND FORMED PART - A method for manufacturing a coated part having very high mechanical properties using hot forming techniques. The method includes:—providing an annealed steel strip or blank or pre-shaped part that was coated with a metal or metal alloy before the annealing—if a strip is provided, cutting a blank from the strip before or after the annealing—optionally forming a pre-shaped part from the blank—heating the blank or preshaped part to a temperature of 500° C. at an average heating rate of 16° C./s or more—further heating the blank or pre-shaped part to a temperature between 700 and 1000° C.—hot forming the blank or preshaped part into a hot formed part—hardening the hot formed part. A method for manufacturing a coated steel strip, blank or pre-shaped part, and a coated steel strip, blank or part and a hot formed part.||06-20-2013|
|20130118647||METHOD OF PRODUCING AN AUSTENITIC STEEL - A method of producing an austenitic steel strip or sheet excellent in resistance to delayed cracking and a steel produced thereby.||05-16-2013|

|20120222777||PROCESS TO MANUFACTURE GRAIN-ORIENTED ELECTRICAL STEEL STRIP AND GRAIN-ORIENTED ELECTRICAL STEEL PRODUCED THEREBY - A process to manufacture grain-oriented electrical steel (GOES) strip and a product produced by the process are provided. A molten silicon-alloyed steel is continuously cast in a strand having a thickness in the range of from 50 to 100 mm and subjected to hot- rolling in a plurality of uni-directional rolling stands to produce final hot-rolled strip coils having a thickness in the range of from 0.7 to 4.0 mm followed by a continuous annealing the hot-rolled strip, cold rolling, continuous annealing the cold-rolled strip to induce primary recrystallisation and, optionally, decarburization and/or nitriding, coating the annealed strip, annealing the coiled strip to induce secondary recrystallisation, continuous thermal flattening annealing of the annealed strip and coating the annealed strip for electric insulation.||09-06-2012|
|20110236719||Method for Manufacturing a Coated Part Using Hot Forming Techniques - A method for manufacturing a coated part having very high mechanical properties using hot forming techniques. The method includes the steps of 1—providing a steel strip; 2—coating the steel strip with a layer of zinc or zinc alloy; 3—heating the coated steel to a temperature between 300° C. and the Ac1 temperature of the steel; 4—cooling the coated steel; 5—cutting a blank from the strip after step 1, 2, 3 or 4; 6—heating the blank to a temperature above the Ac1 temperature of the steel; 7—hot forming the blank into a part; and 8—hardening the hot formed part. The method can also be performed without step 4. The method can also be used for the indirect hot formed method. The method also relates to a method for manufacturing a coated steel strip, and to a coated steel strip, blank or part and a hot formed part.||09-29-2011|
|20110109496||METHOD AND APPARATUS FOR MONITORING THE SURFACES OF SLAG AND MOLTEN METAL IN A MOULD - A method for monitoring the surfaces of slag and molten metal in a mould of a continuous casting apparatus, using radar equipment is disclosed. The radar equipment emits a beam of electromagnetic waves having a bandwidth of at least 20 GHz. This also relates to an apparatus for using the method.||05-12-2011|
