A method for surface pickling of chromium ultrapure ferritic stainless steel in different silicon and manganese contents |
| abstract |
The invention relates to the technical field of steel rolling. A method for pickling the surface of ultra-pure ferritic stainless steel with chromium in different silicon and manganese contents, comprising: electrolytic sodium sulfate concentration, current, electrolysis time and mixed acid concentration; chemical electrolysis medium: the pickling medium is sodium sulfate; mixed acid pickling medium 1: nitric acid 140±30g/l; hydrofluoric acid 10±5g/l; mixed acid pickling medium 2: nitric acid 160±30g/l; hydrofluoric acid 15±5g/l; chemical electrolysis current density: 10‑20 A/ m3; electrolysis time: 12‑84s; chemical electrolysis time: 12‑84s; silicon manganese content is 0‑0.35%, and manganese content is 0‑0.3%. The implementation and application of the present invention solves the problem of pickling on the surface of medium-chromium ultra-pure ferritic stainless steel strips with different silicon and manganese contents, and achieves removal of oxide scale on the surface and passivation through quick and operable adjustment of the pickling process. surface purpose. |
