  • 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 ...

  • DEFECTS SIMULATION OF ROLLING STRIP - CORE

    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.

  • 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.
