| Abstract: | In order to solve the problem which steel adhesion on straight oxygen lance is difficult to deal with and its life is short, the back draught oxygen lance with back draught lower mid pipe and outer pipe is developed. Application shows that the cooling effect of the lance is good, the slag adhesion on the lance can drop automatically, steel adhesion on oxygen lance is easy to de~ with and the average lance life is 312 heats. |
