Abstract:
The effects of
physical-and chemical-properties of melting slag on detachability
of self shielded flux cored electrode (SSFCE) are investigated.
In physical-properties, liner expansion coefficient is mainly
considered. As for chemical-properties, basic index, oxygen
content and composition of slag are studied. An equation can be
obtained by using ceramics and mineralography which may predict
detachability of basic type SSFCE. Other valuable conclusions
are also drawn.
