| Abstract: | In order to solve the problem of adhesion of slag to oxygen lance,a new big taper cone oxygen lance was studied and developed for steelmaking with semi-steel,and also five hole nozzle was designed to replace the four hole nozzle to cooperate with the application of cone oxygen lance.Results by stages of industrial practices shows that the new cone oxygen lance with five holes nozzle has advantage to forming the slag fast,going on smoothly of blowing process and removing the slag sticking on the oxygen lance... |
