FIELD: metallurgy.
SUBSTANCE: method for secondary cooling of a continuously cast round workpiece involves supply of cooling water to surface of workpiece by means of conical atomisers 1 with similar angles of flames. Atomisers are installed around the workpiece at similar distance from its surface, which is 1.0-1.5 R, where R - radius of the workpiece, and is equal to at least 80 mm. Atomiser installation angle around the workpiece is equal to their flame angle.
EFFECT: providing uniform cooling of a workpiece of a round cross section along the perimeter and throughout length; excluding formation of heat stresses leading to occurrence of surface defects; improving metal macrostructure.
