FIELD: metallurgy.
SUBSTANCE: invention is referred to steel casting technologies. The mixture intended for filling inlet channel of steel-teeming ladle includes the following, wt %: flaky graphite 1-4, uniform sand 5-7 and gangue quartz is the rest of mixture. Introduction of inform sand together with rolled form grains will speed up mixture coming out from inlet channel during casting and stabilise steel flow.
EFFECT: improved efficiency of steel-teeming ladle.
