| Abstract: | Bath roller mark, a kind of coating defects of strip arisen on continuous galvanizing line, is caused by the deposition of zinc dross in the bath roll groove,which stick to the surface of strip. It can be influenced by many facetors, such as the disturbance of zinc liquid temperature, zinc liquid compositions and strip tension, etc. In this paper, these factors are discussed on the basis of rollling production experiences obtained by WISCO. The measures to release or eliminate the defects, including control of strip temperature entering into zinc pot, optimizing zinc liquid compositionts and improving the status of bath roller. |
