Method for repairing the tap hole of a converter

A method of repairing the tap hole of a converter under high temperature utilizing a refractory material injection pipe comprising:

• (1) encasing said injection pipe within a perforated mold sleeve,
• (2) inserting said injection pipe encased in said mold sleeve into said tap hole, said injection pipe having at least one refractory material injection opening at the distal end thereof,
• (3) discharging said refractory material within said injection pipe through said injection opening and through said apertures in said perforated mold sleeve such that the refractory material is thereby applied onto the inner surface of said tap hole, and
• (4) cooling substantially the entire length of said injection pipe when said refractory material is applied onto the inner surface of said tap hole.

• (2) moving said injection pipe along said tap hole,
• (3) discharging said refractory material within said injection pipe through said injection opening and through said apertures in said perforated mold such that said refractory material is thereby applied onto the inner surface of said tap hole, and
• (4) cooling substantially the entire length of said injection pipe when said refractory material is applied onto the inner surface of said tap hole.
