| Abstract: | The main cause of pouring basket nozzle blockage is all aluminium content in liquid steel during continuous casting 20MnSi billet in Shiheng special steel works of Jinan iron and steel group.Through analyzing the cause of aluminium in liquid steel,taking changing melting process,controlling oxygen content in liquid steel,reasonably using of ferr alloy and controlling aluminium content in liquid steel>0 006%,the pouring basket nozzle blockage can be effectively prevention. |
