Beschreibung
Zusammenfassung:	The invention relates to ferrous metallurgy and concerns to the hot repair of heat-resistant vessel lining. A method involves blowing of liquid final slag from above at the same time by two overhead tuyeres, which are put into the vessel cavity and are placed on the axle journal in the right and left halves of working space. Distances S1 and S2 on the axle journal from the working surface of the lining to the lateral surface of each tuyere is of Dv/8 -Dv/2.5, where Dv - is diameter of working space of the vessel. The final slag may be additionally processed before blowing. The overhead tuyeres in a process can be moved. The use of the method allows to increase the life term of the vessel aggregates due to effective repair of near pin lining areas.
