Summary: | Hot rolling normalization technology for producing sheets from a low-carbon steel, Steel S355J2,
used in the Bulgarian Metallurgical Plant “STOMANA Industry SA” is under investigation. A newly introduced
automatic application optimization procedure in this technology is an important step that leads to avoiding of
traditional heat treatment, improving of steel mechanical characteristics, increasing of production efficiency, all
resulting in high quality final products. On the basis of the final mechanical rolled-sheet characteristics - yield
strengths, Re, ultimate tensile strengths, Rm, absorbed energies in impact tests, K, and elongations after fracture -
some energy-stress and energy-stress-elongation constructions-spaces have been plotted. These spaces can be
used for general evaluation of the applied rolling technology and for prediction of steel-sheet mechanical
behaviour. |
