Integrated conveying roller way for rolling section steel

The integrated conveying roller way comprises a roller way frame and a plurality of conveying rollers rotationally connected to the roller way frame along a conveying path, roller bodies of the conveying rollers are made of chromium-manganese cast steel alloy, and the main chemical components of the conveying rollers comprise C, Si, Mn, P, S, Cr, Mo, Ni, W and the balance Fe; the conveying roller way further comprises a buffering assembly 2. End plates arranged on the two sides of a traditional roller body are omitted, a casting integrated with the roller body is used, meanwhile, a positioning key at the end of a roller shaft is omitted, interference fit between the roller shaft and the roller body is changed, the manufacturing and installing procedures of the conveying roller are reduced, the loss of the conveying roller is reduced, and the service life of the conveying roller is prolonged; meanwhile, the buffering assemblies are arranged below the ends of the roller shafts, impact borne by the conveying rol
