Converter for refining liquid metal

摘要

A converter for refining liquid metals having a cylindrical horizontally disposed vessel (1) with a first opening (6) for charging and pouring and a second opening (13) circumferentially and longitudinally displaced from the first opening for exhaust gases to escape, is disclosed. The circumferential displacement is sufficient to prevent liquid metal from pouring from the second opening (13) when the vessel is rotated from a first position for charging materials into the vessel (1) through the first opening (6) to a second position for pouring the contents of the vessel (1) from opening (6). Cool air is provided to a region between the vessel (1) and a jacket (15) surrounding the vessel (1). A hood (14) collects the exhaust gases from the second opening (13) in any position to which the vessel (1) is rotated when it is used. End and circumferential seals structures are provided where hood (14) longitudinally and circumferentially contacts jacket (15).
