Patent ES-431907-A1 (ES)
Title: Apparatus and method for refining a metal melt
IPC: C21C7/072
Filed: 1974-11-13
Abstract: An unfinished steel melt is tapped from its primary melter into an upright ladle having one or more nozzles in its side above the level of the melt. The ladle is then tilted in the direction of the nozzle or nozzles so that it covers them, oxidizing gases, slag formers, alloying elements, etc., then being injected into the melt below its surface as a refining and finishing operation. The ladle has an inductive stirrer that tilts with the ladle and may be used when the ladle is upright or tilted. By tilting the ladle the top surface of the melt is increased in area with a consequent increase in the area of contact between the melt and the slag which, together with the fact that the refining and finishing materials are injected directly into the melt, while the melt may be inductively stirred at the same time, provides for rapid and thorough refining and, if desired, alloying. After refining and finishing, the melt is cast in the molds. Only the single ladle is required to receive the melt from the primary melter, to refine and finish the melt, and to transport the melt to the casting location.

Title: Method of lining pipe
IPC: B29C63/00
Filed: 1980-09-05
Abstract: A metal pipe is internally lined by a thin thermoplastic tube of originally smaller outside dia. than the inside dia. of the pipe.
