Method of BOF Operation for Removal of Skull Attached at Oxygen Blowing Lance

摘要

invention lance in Songshan converter now attached to the removal method on that, the goal converter blow to induce foaming of the slag of the slag on the surface of the coating operation by now attached to lance the lance face / now / to now due to the thermal expansion difference between the slag coating layer by generating the crack provides a method of removing the now by its own force to. ; of the present invention to achieve the above objective method for performing operations in the converter blowing oxygen through a lance while Songshan to a charter that is charged to the converter,, ; furnace of the blow step increases and raising the height of the Songshan flow so that the slag foaming lance induction, ; If you see signs of decreasing the Songshan flow in the induction process of slow ping the slag foaming lance is lowered and attached to the lance height Now that it comprises the step of coating the surface of the slag in the converter according to the operation method for the removal of the now attached to the lance in the technical aspect Songshan.
