FIELD: process engineering.
SUBSTANCE: proposed method comprises spraying the coolant on rough strip or strip 4. Homogeneous uniform temperature over strip transverse profile improving strip properties and decreasing wear of roll is ensured by shielding rough strip or strip 4 on edges against coolant feed. For this, shields 14, 15 are used. Similarly, shield 20 may be arranged in zone of looper or in cooler between roughing and finishing stands.
EFFECT: improved cooling of rough strip or strip 4 in hot rolling mill with rolls 6, 7.
