FIELD: heat treatment in metallurgy processes. SUBSTANCE: proposed device includes loading chute, revolving hardening drum, sectional collector for delivery of quenching medium which is mounted inside drum and inclined cantilever-type swivel chute made in form of pipe. Side surface of chute located before hardening drum have holes engageable with loading chute; sections of side surface of swivel chute located in hardening drum opposite to holes have different length. EFFECT: extended range of articles; possibility of regulating hardening time depending on ball diameter. 6 dwg _
