20090095438 | Method and Apparatus for Continuous Casting - The invention relates to a method for the continuous casting of slab, thin slab, bloom, preliminary section, round section, tubular section or billet strands ( | 04-16-2009 |
20090151821 | Method and Device Adjusting Targeted Combinations of Properties of Polyphase Steel - Compared to conventional steel products, polyphase steels have a significantly improved combination of resistance and ductility and are therefore becoming more and more important—especially for the automobile industry. The currently most important steel groups for the automobile industry are dual phase steels and TRIP steels. The production of different polyphase steel resistance categories, carried out directly on a hot strip, for meeting various requirements, requires a highly extensive know-how and firstly a corresponding adaptation of the alloy elements. According to the invention, a heat treatment ( | 06-18-2009 |
20090217945 | Method and Device for Cleaning Slabs, Thin Slabs, Profiled Elements, or Similar - Disclosed is a method for removing loose scale and other foreign matter from the top and/or bottom face of a cast product ( | 09-03-2009 |
20090260728 | Method and installation for producing hot-rolled strip from austenitic stainlesssteels - A method for producing hot-rolled strip from austenitic stainless steels. In a first step, a cast product is subjected to a rolling operation in a rolling mill with a finishing train, and, in a second step, a heat treatment is carried out to prevent susceptibility to corrosion, especially intergranular corrosion due to chromium carbide precipitation. To establish the final rolling temperature (T | 10-22-2009 |
20090301157 | METHOD OF AND APPARATUS FOR HOT ROLLING A THIN SILICON-STEEL WORKPIECE INTO SHEET STEEL - The invention relates to a method and a system for the production of hot-rolled strip silicon-alloy steel for further processing into grain-oriented sheets, such as electrical sheets, wherein a cast product, in this case a thin slab, for example, with a maximum thickness of 120 mm, is subjected to thermal pretreatment and to a subsequent rolling process on a hot-rolling line to set a desired recrystallization state. The invention proposes an intake temperature (T | 12-10-2009 |
20100132910 | Method For Detecting And Classifying Surface Defects On Continuously Cast Slabs - A method for the detection and classification of surface defects on continuously cast products using topographical information about the appearance of continuously cast surface defects and/or flaws are determined with respect to their exact position, evaluated with respect to their location and dimensions, and eliminated in accordance with the evaluation prior to further machining of the product, or are prevented by optimizing the process. The defects and/or flaws on the slab surface of the continuously cast preliminary product are detected and are stored with respect to their exact position and a detection of defects and/or flaws on the finished product is carried out and stored with respect to their exact position, and in that the information from the preliminary product is then compared with the information from the surface inspection on the finished product. Only the information which has led to, or can lead to, defects on the finished product is considered for the elimination of defects and/or flaws on the preliminary product. | 06-03-2010 |
20100175452 | METHOD FOR HOT ROLLING AND FOR HEAT TREATMENT OF A STEEL STRIP - The invention relates to a process for hot rolling and for heat treatment of a strip ( | 07-15-2010 |
20120036909 | METHOD AND DEVICE FOR CLEANING SLABS, THIN SLABS, PROFILED ELEMENTS, OR SIMILAR - A method for removing loose scale and other foreign matter from the top and/or bottom face of a cast product with the aid of flowable media which are sprayed onto the cast product by a cleaning device having at least one spraying apparatus that is disposed above the cast product and at least one spraying apparatus that is arranged below the cast product. According to the method, the amount of media and/or the effective width and/or the pressure of the media is/are controlled separately and independently of time for each spraying apparatus. | 02-16-2012 |
20120111527 | METHOD AND APPARATUS FOR CONTINUOUS CASTING - A method for continuous casting from molten metal, where metal flows vertically downward from a mold and the metal strip is then guided vertically downward along a vertical strand guide, cooling as it moves. The strip is then deflected from the vertical direction to the horizontal direction. In the terminal area of the deflection of the strip into the horizontal direction or after the deflection into the horizontal direction, a mechanical deformation of the strip is carried out. The strip is cooled at a heat-transfer coefficient of 3,000 to 10,000 W/(m | 05-10-2012 |
