摘要

There are different reasons for purging a metal bath. The operations are varied, for example the purging gas can be used as a reactive gas being part of the metallurgical process or as an inert gas using the rising gas bubbles for agitation only. The effects of gas purging are discussed in more detail for the anode furnace and the converter. For an optimised arrangement of numbers and position of all single plugs in the furnace, mathematical modelling- the CFD Computational Fluid Dynamics method - is used. In 1989 Inco installed the first porous plugs and an oxygen lance in a Peirce Smith Converter shell. Since 1994 there has been increasing interest in purging plugs in the copper industry. For copper production alone, the RHI group has installed more than 100 single porous plug elements in different furnaces. Gas stirring systems arc used from Canada to Chile and also in Europe, Africa, Asia and Australia. On some selected examples the performance and benefits of these systems are shown and also the newest purging system - the MET KIN System - will be introduced.
