The method of alternation of the nozzle down converter and method of replacement

摘要

The "method of alternation of nozzle bottom of converter and method of substitution.It is provided a method of alternation of a nozzle blowing bottom of converter alternating nozzles blowing bottom by provision of a new nozzle blowing bottom in a brick applyThe level of drilling, which is prepared beforehand in a position, on a layer of refractory body that covers a bottom of a converter.In an other position than where a nozzle blowing bottom current is prepared, the method including the steps of: setting, as a reference plane.A surface of a housing covering an exterior of the iron converter or face of a flange affixed to the housing of the iron,And the provision of advance of a brick applicable drilling in a position, on the layer of refractory body, not to a position in which a nozzle current is prepared.So that a direction of drilling of the brick applicable drilling is perpendicular to the reference plane; the drilling of the brick applicable drilling in a direction perpendicular to the planeA reference from an outside of the carcass of iron.A drilling machine; and the insertion of a new nozzle blowing converter in a hollow hole bottom formed by a hole drilled through the brick applicable to perfurau00e7They will be.
