| description | The problem of improving the steel casting quality of pipeline
valves made by electroslag casting is considered. An integrated
approach to the melt preparation in electroslag casting is proposed
including its deep deoxidation with a rare earth metal agent
and introducing a modifying complex containing nanodispersed
pyrocarbon particles, which forms a fine ferrite-pearlite structure
with small globular nonmetallic inclusions located in the dendrite
axes. This permits to produce castings made of wide class of steels
with a high cold resistance level. |
