Abstract (en)

[origin: US5330690A] PCT No. PCT/DE91/00021 Sec. 371 Date Aug. 4, 1992 Sec. 102(e) Date Aug. 4, 1992 PCT Filed Jan. 14, 1991 PCT Pub. No. WO91/12103 PCT Pub. Date Aug. 22, 1991.A process for renewing the refractory lining of a ladle for casting steel and of similar metallurgical vessels. While the ladle (10) is still hot, the slag (S) still adhering to the inner surface (26) is melted off from the remaining lining (2) with the aid of a high-temperature burner (9) operating under reducing conditions and allowed to run out of the ladle (10) in the molten condition. After cooling, the glassy surface of the remaining lining (2) is roughened. The new refractory lining (30) is then applied by casting, with the aid of a template.
