Abstract
The utility model relates to a natural gas annealing furnace roller comprising a roller body, a left shaft head and a right shaft head, wherein the left shaft head and the right shaft head are arranged on two sides of the roller body. The left shaft head and the right shaft head are connected and fixed with the roller body through a shaft neck. The roller body is provided with a plurality of roller rings. A water supply hole is respectively arranged in the left shaft head and the right shaft head. The wall of each roller ring is provided with a quincunx opening hole. The position on the roller body, close to a left shaft neck, is provided with a baffle ring. Fireproof fiber cotton is respectively arranged in the left shaft neck and a right shaft neck. The end face of the left shaft neck and the end face of the right shaft neck are provided with heat resistant steel baffle pieces. Compared with the prior art, the water supply hole is respectively arranged in the left shaft head and the right shaft head of the roller body, the surface of the roller body is provided with the roller rings made from fireproof materials, so the natural gas annealing furnace roller reduces weight, improves strength and wear-resisting property, can bear large amount of the weight, and effectively protects bearings at two ends of the roller body due to the fact that a water cooling temperature-lowering way is adopted to cool the left shaft head and the right shaft head during using, and achieves the heat-resistant temperature of 1200 DEG C. The natural gas annealing furnace roller can lower influence of the high temperature to the bearings at two ends of the roller body, and prolongs service life of the roller body and the bearings.
