CAST IRON Russian patent published in 2006 - IPC C22C37/06 C22C37/10 

FIELD: ferrous metallurgy; production of alloyed cast irons.

SUBSTANCE: the invention is pertaining to the field of ferrous metallurgy, in particular, to production of alloyed cast irons and may be used for manufacture of the details working in the conditions of intensive wear-out at the high temperatures up to 900°C, for example - the rolls of the hot rolling, roll sleeves and rolls of the wire and band mills and others. The cast iron contains (in mass %):carbon - 2.8-3.2; silicon - 0.2-0.6; manganese - 0.2-0.6; chrome - 20.0-26.0; molybdenum - 0.8-1.2; titanium - 0.2-0.4; vanadium - 3.5-4.2; copper - 0.5-0.8; boron - 0.01-0.03; tungsten - 1.8-2.2; iron - the rest. The technical result is the increased wear resistance, heat-resistance and heat stability.

EFFECT: the invention ensures the increased wear resistance, heat-resistance and heat stability.
