Description

Technical Field

[0001] The utility model relates to the technical field of continuous casting equipment, and more specifically to a heat-conveying roller table heat preservation device. Background Art

[0002] Hot delivery and hot loading of continuous casting billets is a production process in which the high-temperature continuous casting billets are transported into a heating furnace and then rolled. This can effectively reduce energy consumption and improve the quality of finished products.

[0003] The continuous casting billet transport roller is one of the main supporting equipment for hot delivery and hot loading of continuous casting billets. During the transportation process, the temperature of the continuous casting billet drops rapidly due to its own radiation heat dissipation, convection heat dissipation with the surrounding air, and contact heat conduction between it and the conveyor roller. Therefore, it is necessary to install an insulation cover on the transport roller.

[0004] At present, the existing hot delivery roller insulation cover mostly adopts the three-sided insulation form. For example, the existing patent CN215355347U discloses a billet out of furnace roller insulation cover, including an insulation cover body, which can be detachably covered on the side baffles on both sides of the roller, and is opened at both ends along the movement direction of the roller; a crossbeam is arranged on the upper surface of the insulation cover body; and a reinforcing rib is arranged on the inner side of the insulation cover body. Since the insulation material is only placed above and on both sides of the roller, the heat can be dissipated from the roller surface to the bottom of the roller by air convection, etc., so the insulation effect is not ideal.
