Claims (5)

  1. Na2SO4농도가 50-300g/l, 바람직하게는 100-200g/l인 Na2SO4의 중성수용액에서 온도 20-90℃, 바람직하게는 60-80℃하에 전해적 산세척중의 양극 및 음극 전류밀도를 1-50A/d㎡, 바람직하게는 10-30A/d㎡으로하여 고급강의 열스트립을 처음 양극으로 시작하여 음극으로 교대로 산세척 시키는 고급강 스트립, 특히 고급강의 열스트립의 전해적 산체척 방법에 있어서, 통상의 HNO3/HF 혼합산과 동일한 음이온을 함유한 중성염 수용액에서 고급강의 열스트립을 연속적으로 양극과 음극으로 교대로 산세척시키는 것을 특징으로 하는 고급강 스트립의 전해적 산세척 방법.
  2. 제1항에 있어서, 중성염 수용액이 NaNO3및 NaF의 용액인 것을 특징으로 하는 방법.
  3. 제2항에 있어서, NaNO3농도가 100-400g/l, 바람직하게는 200-300g/l이며, NaF농도가 10-100g/, 바람직하게는 40-60g/l인 것을 특징으로 하는 방법.
  4. 제2항에 있어서, NaNO3/NaF용액 농도가 20-90℃, 바람직하게는 60-80℃인 것을 특징으로 하는 방법.
  5. 제2항에 있어서, NaNO3/NaF용액에서 전해적 산세척동안 양극 및 음극 전류밀도가 1-50A/d㎡, 바람직하게는 10-30A/d㎡인 것을 특징으로 하는 방법.
