FIELD: metallurgy.
SUBSTANCE: prior to hot rolling continuously cast slab is cut. When cutting end surface of head part attached to slab inside concave shape, and end surface of tail section - outwardly curved shape, which cutting head and tail portions of slab is performed by a curve symmetrical axial line of slab width. Height of arc H representing maximum value of head portion or concavity of maximum convexity of tail section is less than 50 mm.
EFFECT: decreased length of deformed sections of head and tail parts of slab and reduced volume of their cutting.
