Patent ID: 7182891

Claim:
Process for a hot repair of a refractory lining in a metallurgical vessel by throwing a sack including a non-basic refractory batch consisting of: 65–90 M-% non-basic refractory material with a grain-size fraction of <15 mm, and 10–35 M-% of a combination of at least one phosphatic and at least one silicatic component, or 10–35 M-% of a combination of at least one C-containing component and at least one silicatic component, as well as 0 to <2 M-% of micro-silica; and 0 to <4 M-% of oil, wherein at least one of the phosphatic and silicatic components forms a molten phase at temperatures >500° C., in dry form on a damaged site so that the sack splits and the batch gets in contact with the refractory lining.
