METHOD OF CONTROLLED COOLING OF HOT-ROLLED STRIP ROLL AND DEVICE FOR METHOD IMPLEMENTATION Russian patent published in 2010 - IPC C21D9/52 B21B45/02 

FIELD: metallurgy.

SUBSTANCE: invention refers to metallurgy, particularly cooling of hot-rolled strip roll. To reduce structural irregularity of metal, maintain homogeneous physical and mechanical properties along strip length and width, and increase yield, hot-roller strip roll placed horizontally is cooled by pressure difference generation in the roll cavity formed by two hemispheric vessels positioned at the roll ends, with one vessel connected to receiver and another vessel connected to ejector to change underpressure grade. Device for implementation of horizontal roll cooling method includes vessels with coolant, Each vessel is made in the form of hemisphere with drive for horizontal movement against the roll ends and features centering locks. One vessel is connected to receiver by coolant feed pipe, the other vessel is connected by coolant drainage pipe to ejector and cooler to create pressure difference at the roll ends.

EFFECT: improved efficiency of hot-rolled strip roll cooling.
