摘要：

The results of studying the properties of prototypes obtained at the production site of the QazCarbon LLP (Karaganda, Republic of Kazakhstan) are presented. Grinding balls were smelted of low-chromium cast iron treated with modifiers of various nature. Boron-barium-containing materials were used as modifiers. It was found that the use of boron-barium- containing additives as modifiers qualitatively and quantitatively changes the structure of the alloy under study. After modification, the structure becomes more dispersed, the quantitative ratio between the main structural components:ledeburite, pearlite and carbide phase, changes. Such changing the structure has a positive effect on the impact resistance of the samples.
