  • WO2013164847A2 - A method to reduce end defects in rolling ...

    The present invention aims at reducing the cropping losses formed during reversible pass hot rolling of flat ended bloom into bars by designing the preform end shapes using finite element analysis and a method to provide the designed preform end shapes to the input blooms. A three dimensional simulation of the reversible pass hot rolling process with flat ended input bloom predicts ...

    defect for steel wheel rim Ping Lu1,2, Yun Kai Zhang1,2 and Feng Ma3 ... simulation study of the rim rolling process. However, all these researches have focused on simple profile ring rolling such as rectangular cross section. Also, these rings have been bulk specimens, and the springback


    First phase of hot rolling process have been done by software simulation DEFORM 3D setting to the limited condition for samples with surface defects. Samples of material with low-carbon steel of sizes h x b x l have been chosen and the surface defects shape „U" and „V" of scores have been injected artificially by software.

    Hot Rolling Scrap Reduction through Edge Cracking and Surface Defects Control Improving Energy Efficiency in Hot Rolling by Increasing Recovery Rates Hot rolling of large ingots is the predominant process for producing plate, sheet, and foil aluminum products. Hot rolling has typical recovery rates of 82%, because 18% of the original

  • Prediction of the Change of Surface Micro-Defects in Plate ...

    Experiments were performed in order to verify the validity of the simulation results. Changes in defect shape in rolling were found to fall under two main categories: opening type and closing type. The influences of rolling conditions (roll diameter, lubrication, pass schedule, etc.) on existing defects after rolling were revealed.
