Abstract

Способ относится к вторичному удалению окалины с металлических полос, а именно, с тех, которые перемещают во время горячей прокатки стальных полос путем нагнетания воды на их поверхность с помощью коллекторов с соплами, в которые подают воду под давлением. Согласно с изобретением, в соплах создают низкое гидравлическое давление, не превышающее 30 бар (желательно ниже 10 бар, но не ниже 4 бар), при этом для обеспечения термического воздействия воды, которую подают на поверхность полосы, указанные сопла регулируют таким образом, чтобы плотность теплового потока, выходящего из полосы в результате охлаждения ее поверхности водой составляла от 6,5 до 20 МВт/мпри температуре полосы от 900 до 1100 º С.
