OPTIMIZATION OF THE COMPOSITION AND TECHNOLOGY OF THE ABRASION-RESISTANT CAST-IRONS MELTING

Abstract

Тhе methods of the service durability increase of wear resistant cast irons are analyzed. There are developed the compositions of economically-alloyed cast irons with low content of nickel and other deficient elements, being exploited both in cast and in thermotreated state. The composition of antifriction gray cast iron with increased exploitation characteristics is offered.
