FIELD: processes for descaling moving steel strips designed for further cold rolling.
SUBSTANCE: method comprises steps of S-shaped embracing of rotating rollers by means of moving strip. Scale is completely removed due to additional twice bending of trip section by means of said rollers in opposite directions along circle arc while setting bending radius of first pair of rollers R1 = (60 - 64)X H/δT, m; and in second pair of rollers R2 = (65 - 70) x h/δT, m; h - thickness of strip, mm; δT - limit yield of strip metal, MPa. Radius values of lengthwise bending of strip middle along its width may be Rn = (70 - 85) x h, mm.
EFFECT: enhanced surface roughness of hot rolled strips, reduced cost of making strips subjected to further cold rolling.
