FIELD: metallurgy.
SUBSTANCE: proposed method comprises adding metallic aluminium reducing agent directly into melt flow discharged from arc furnace into mould during the entire period of flow discharge in amount of 0.1-1.5 wt % of the content of zirconium dioxide in melt composition. Aluminium powder or shots are used as metallic aluminium.
EFFECT: higher bending strength and abrasive durability.
