“…First, calculations of the cooling mode for L-section steel and U-section steel made of 09G2S steel were performed for 450 MMK mill products (strength class of 390 MPa is of practical interest) [16]. Nowadays, KCU impact elasticity not less than 29 J/cm 2 and 34 J/cm 2 for 09G2S steel at temperature -70°C for rolling steel of strength class 345, according to requirements of GOST 19281-2014, is provided for hot-rolled state only if vanadium microalloying is used with vanadium content in steel of 0.06%.…”

“…Because of the complexity of the shape of cross-section of H-beams, its online controlled cooling is prone to uneven cooling phenomenon, which will affect the rolling shape of cross-section and performance uniformity, the products are prone to produce out of square, web waves and crack defects [7][8]. Mature cooling theory and technology has not formed in H-beams hot rolling production line, but it has attracted attention of the enterprises in domestic and foreign in recent years, related research have been reported in Japan, Germany, Italy and other countries [9].…”
