PURPOSE:To remarkably improve the durability of a lance nozzle for steel production by coating the lance nozzle with TiN, TiC or Ti(C,N). CONSTITUTION:A lance nozzle for steel production is usually made of Cu. Molten slag sticks to the nozzle and said nozzle often is corroded. In order to prevent the sticking of molten slag, a TiN, TiC or Ti(C,N) coating of about 5mum thickness is formed on the lance nozzle for steel production. |
