ROLL FOR FEEDING MATERIAL TO THE FURNACE USED IN THE PROCESSES OF CONTINUOUS CASTING AND ROLLING THIN CARBON STEEL SLABS Russian patent published in 2018 - IPC C03B35/18 B21B27/08 

FIELD: technological processes.

SUBSTANCE: invention relates to processes of sustained casting and rolling of thin carbon steel slabs. In particular, the invention relates to a water cooling roll for loading a material, in particular thin slabs, in the furnace for heating, maintaining temperature and storing, located between the pouring and roughing sections in the process of continuous casting and rolling of thin carbon steel slabs. Water cooling roll includes a first hollow shaft that is disposed along first longitudinal axis and which comprises outer surface and inner surface. Outer surface of the first shaft is covered with an insulating and/or fireproof material, the inner surface of the first shaft forms the inner cavity of the first shaft. Roll comprises support wheels for supporting the feed material, which are rigidly fixed to the outer surface of the first shaft. Roll comprises a second shaft disposed in the inner cavity of the first shaft coaxially with the first shaft. Outer surface of the second shaft has a diameter smaller than the diameter of the first shaft inner cavity, thereby forming a gap between the first shaft and the second shaft. Roll comprises centering rings disposed within the gap and rigidly connected to the second shaft integrally. Diameter of the centering rings is less than the diameter of the first shaft inner cavity. Roll comprises means for circulating cooling water installed inside the second shaft.

EFFECT: technical result is the limitation of the ability to dissipate heat by the roll.
