Analysis of coiling stable roll of hot-dip galvanized strip

Abstract The coiling stable roll of hot-dip galvanized is a defect formed in the galvanizing process. zinc slags and floating foreign matters pot will directly or indirectly adhere to surface stabilizer with flow liquid. When strip steel contacts roll, slag extrude deform iron base plate form pits. In this paper. causes defects were analyzed. There two methods eliminate that is, reduce generation accumulation pot. main measures are first control temperature entering can molten zinc, then amount residual bottom residue before goes online. Another ensure cleanliness it enters zinc. Based on this, implemented are: improving cleaning ability section reducing during annealing inhibit formation powder furnace head area.
