| Abstract: | The surface and the morphology observation of the black spots existing the head,the tail and two sides of the strip on pickling line was compared with the normal strip. It is thought that the black spots formed due to the incomplete dissoving of the ferric oxide. The pickling process parameters is optimized by analyzing the influence of pickling process parameters to pickling capacity,so the black spots is effectively reduced. |

| Keywords: | pickling line the black spots concentration temperature |
