Structure Formation in Strip Steel by Thermal Strengthening

The results of research of microstructure of the strips from low carbon steel 45x6 and 30x8 mm in hot-rolling condition and after accelerated cooling of different intensity and schemes of the coolers movement in the cooling chambers are shown. A defind a temperature interval of phase transformations is in the cross-sections area of strips starting from axis of symmetry towards the edges.
