Abstract


Slab continuously cast billets 270 ? 1200 mm have a profile distortion crown narrow faces at the JSC "Ural Steel". Series of tests to determine the mechanical properties of cast metal samples of different chemical composition of the tempera­ture were conducted. The values of tensile strength and yield strength of steel casted 09G2C, 15HSND and St3sp at tempera­tures ranging from 400 to 1400 ?C were defined. Dependences of the conditional strength and tensile strength of the metal compo­sition different from the temperature were established. They determine the length of the frame supporting the mold to prevent formation of a defect of convexity in the form of narrow edges of slab continuous casting.
