The invention discloses high-strength wear-resistant
wind power ductile iron and a
processing technology thereof, and belongs to the technical field of
casting. The
processing technology of the high-strength wear-resistant
wind power ductile iron comprises the following steps: A1, sequentially adding waste steel, a carburant,
pig iron,
foundry returns and
ferroniobium into an
intermediate frequency furnace, standing after all furnace charges are molten, and removing
slag; a2, a spheroidizing agent, a nucleating agent,
metal antimony,
titanium carbide and a covering agent are sequentially added to the bottom of a steel
ladle, and then molten iron in the step A1 is poured into the steel
ladle for spheroidizing and
inoculation; a3, the molten iron obtained after spheroidizing and
inoculation is subjected to slagging-off and then poured into a
casting mold, and a
stream inoculant is added in the pouring process; a4, after pouring is finished, slowly cooling in the sand mold to below 400 DEG C, and removing a
casting from the
casting mold; and A5, the casting is subjected to
pulse current quenching treatment and then subjected to
pulse current normalizing treatment, and the high-strength wear-resistant
wind power ductile iron is obtained. The prepared high-strength wear-resistant wind power ductile iron is high in strength and good in
wear resistance, and the low-temperature
impact performance meets the requirement of QT500-14AL.
