The working body temperature field and stresses field of desulfurizing lance has been dynamically simulated with the finite element software Ansys to show the dynamic thermal stresses distribution within lance in a duty cycle.

To meet the requirements of the application circumstances and the usage of desulfurizing lance of pig iron in W.

Through using some technical measures consisted of short process of powdering,sulfurizing injecting process,improving collection powder system and automatical pot to pot of injecting powder,etc,the trouble ratio of equipment and the production cost are decreased,thus the smooth operation of equipment is achieved and the requirement of injecting coal powder is met.
