| titleOfInvention | Large rollers for roller tables of hot rolling equipment |
| abstract | The present invention relates to a large-sized roller for a roller table of a hot rolling device, in particular, having a cylindrical roller body and including a central axis coupled to both sides of the roller body, wherein the roller body modifies the bulletproof material of the cast steel product. Made by roll vertical casting method, the thermal shock absorbing portion absorbing thermal shock on the surface of the roller body is formed in the shape of lattice or honeycomb, and a plurality of heat exchange fins are formed on the inner circumferential surface of the roller body to form a roller body. The high toughness, high strength, and impact resistance of the roller are improved by applying the cast steel ballistic material, which is mainly used for tanks or armored vehicles, and the thermal shock buffer part is formed on the surface of the roller with a hardened layer of honeycomb shape and boundary grooves. The effects of thermal shock on rollers operating in high temperature and rapid heat changes It minimizes the cracks generated on the surface of the roller by absorbing it, and maximizes the cooling efficiency by plural heat exchanger fins protruding on the inner circumferential surface of the roller body. Formed to maximize the cross-sectional coefficient of the roller to withstand high loads and high impact well, and to reduce the thickness of the material of the large rollers for hot-rolling device compared to the conventional, but to avoid problems in strength (about 50Kg / mm 2 Bulletproof materials are modulated to 100Kg / mm 2 or more, and the weight of the product can be significantly reduced to reduce the production cost of the product, and the motor that drives the roller forward and backward as the weight of the roller decreases. The load on the roller is reduced, which reduces the amount of power consumed. The present invention relates to a large roller for a roller table of a hot rolling device, in which rotation and reverse rotation are performed quickly to improve product productivity of the hot rolling device. |
