| description | The problem of improving the quality of centrifugal pipes made of
stainless steel is considered. It is proposed to tap ferro-titanium in
a furnace under slag, after its deep deoxidation by REM-containing
additive for receiving such pipes with high mechanical and service
properties. Before tapping the melt from the furnace, the melt
must be processed by nano-dispersed titanium carbonitride in
the modifying briquette composition. Implementing the above
conditions allows increasing the tensile strength of cast metal by
10–15 %, plasticity by 30–45 % with increasing resistance to
intergranular corrosion (IGC) in the casting section. |
