Study of Mechanical Properties of the Surface Layer of Continuous Casting Slab
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.
