FIELD: metallurgy.
SUBSTANCE: aluminium gas-thermal coating is deposited on slab wide faces. Note here that said coating features depth defined by the formula: hn=[a0+a1·τ+a3·τ+a3·h]±0.02 mm, where hn os coating thickness, mm; t is slab heating temperature, °C; τ is slab heating duration, h; h is slab thickness, mm; a0 =-1.1525 mm; a1=0.001088 mm/°C; a2=0.1425 mm/h; a3=-0,000675 are empirical factors defined by experience.
EFFECT: decreased thickness of defect layer after slab hot rolling.
