FIELD: metallurgy. ^ SUBSTANCE: according to invention, one or two continuous casting plants are used to form billet. Steel is cast at a rate from higher than 3 m/min to approximately to 10 m/min to get thin slab which is cut into longitudinal sections and driven into furnace to level up temperature and are heated by induction heating to rolling temperature. At an increase of casting speed, reduced time holding in furnace is compensated by more effective differentiated heating of longitudinal sections in head part, middle part and reduced heating in tail part. After heating, billets are driven into finishing rolling mill connected directly with outlet of furnace to equalize temperature and are subjected to rolling. ^ EFFECT: provision of casting and rolling at continuous or semicontinuous mode without elongation of furnace to equalize temperature at high speed of passing of billets. ^ 24 cl, 3 dwg |
