Slag splashing is a way of maintaining converters lining, started at the Fos steel
plant in December 2003. Systematic slag splashing on converters lining, by nitrogen
injection with the top lance, after tapping, protects refractory. The aim of the project
is to disconnect the two converters, from the refractory point of view, and to reach
a refractory lining lifetime of 5,000 heats.
