Description

Technical Field

[0001] The utility model relates to the technical field of continuous casting machines, in particular to a free roller cooling device for a continuous casting machine. Background Art

[0002] During the continuous steel casting process, the working surface temperature of the continuous casting machine is relatively high, and coolant is required to cool the free roller. However, there are some problems with the existing cooling methods. Due to the limitations of production processes and other conditions, the free roller is generally straight-through, that is, there are usually no structures such as baffles inside it to extend the coolant's travel distance. This results in the coolant entering the roller through the rotary joint installed at one end of the free roller and then flowing out from the rotary joint installed at the other end. The coolant stays in the free roller for a short time, which is not conducive to fully removing the heat from the free roller. In addition, whether it is a core shaft segmented roller or a fully disconnected segmented roller, there is a situation where the cooling channel is far away from the roller surface, resulting in poor cooling effect.

[0003] Patent publication number CN2710796Y discloses a cooling device for a sector free roller and its bearing seat. The patent specifically discloses "a cooling device for a sector free roller and its bearing seat, in which cooling water is supplied to the free roller and the bearing seat respectively, and the roller cooling water pipe is connected to the transition pad, the bearing seat, the end cover, the built-in rotary joint, and the roller core shaft through the sector frame; the return water pipe of the free roller is connected to the end cover through the sector frame; the cooling water pipe of the bearing seat is connected to the bearing seat through the sector frame, and the return water pipe of the bearing seat is connected to the bearing seat through the sector frame." The technical solution achieves the technical effect of "no metal hose, simple piping, and convenient inspection and maintenance of the sector equipment."

[0004] Although this patent has achieved "facilitating the inspection and maintenance of the sector equipment" in actual use, the return pipe of the free roller may be clogged with impurities, so further improvement is needed. Utility Model Content
