Efficient radiating air cooling roller

Abstract

The invention relates to the technical field of casting rollers, in particular to an efficient radiating air cooling roller. The efficient radiating air cooling roller comprises a roller body and roller shafts welded to the two ends of the roller body. A plurality of radiating channels for radiating of the roller body are formed in the roller body. Reinforcing rib plates used for improving the bearing strength of the radiating channels are welded in the radiating channels. Radiating fans used for accelerating radiating are further arranged at the two ends of the radiating channels. The six radiating channels are evenly distributed in the roller body with the roller shafts as the circle centers. The extension lines of the reinforcing rib plates pass through the circle centers of the roller shafts. The radiating fans are fixedly connected to the ends of the reinforcing rib plates through rotary shafts. Effective radiating of the surface of the roller body is achieved through the radiating channels formed in the outer edge of the roller body, and radiating is accelerated through the radiating fans in the channels. The bearing strength of the hollow channels is advantageously improved through the reinforcing rib plates welded in the channels, the condition that the roller body is bent after long-time usage is prevented, the radiating efficiency of the roller body is effectively improved, and the service life is prolonged on the premise that the using efficiency of the roller body is not influenced.

Description

technical field [0001] The invention relates to the technical field of casting rolls, in particular to a high-efficiency heat dissipation air-cooled roll. Background technique [0002] The air-cooled roller is solid nodular cast iron, which is changed to a centrifugally cast hollow wear-resistant alloy furnace roller, which is used to convey and cool the materials after high-temperature treatment. The existing air-cooled rollers generally use quartz ceramics with a hollow structure. Quartz ceramics have high strength and durability High temperature, small thermal expansion, and good chemical stability, but the hollow area inside the roller body is large, and it is easy to bend and deform after long-term use. Contents of the invention [0003] In order to overcome the shortcomings of the existing hollow structure, which is easy to bend and deform and has poor heat dissipation effect, the present invention provides a high-efficiency heat dissipation air-cooled roller, which ...
