Abrasion-resistant cast iron

Samples (model 340X18 НМЛ) tested in accordance with GOST 9454-78, with a view to determining the mechanical properties of shock-abrasive wear, in accredited testing laboratory "Rope-testing laboratory " CPL PA NMBP. The average value of impact ductility was 0.98 kgm / cm.

The technology used in NMMC production association Navoi Machine Building Plant (PA "NMBP"). The castings "abrasion-resistant cast iron" (340X18 НМЛ) used in rotary crushers "SEMSO" of the fourth crushing stage of NMMC enterprises.

The invention relates to metallurgy, in particular to wear-resisting high-alloy cast iron, working in the conditions of the abrasive and impact-abrasive wear.

Task of the invention: Toughening and impact - abrasive wear resistance of cast iron and savings of alloy elements in its manufacture.

Character of the invention:

There is provided the manufacturing technology of abrasion-resistant cast iron, containing components: carbonium; silicon; manganese; chrome; nickel; molybdenum; sulfur; phosphorus; iron in appointed percentage.

Manufacturing technology patented by Republic of Uzbekistan № IAP 2009 0345 UZ. There is a “know how” for this technology. Technology transfer is possible only on licensing agreement.
