Sliding rail in pushing device in sintering furnace

The utility model discloses a slide rail in a pushing device in a sintering furnace, which comprises a slide rail body made of isostatic pressing graphite materials, a plurality of pulley grooves for installing pulleys are arranged on the slide rail body at equal intervals, and axle grooves for installing axles are arranged on the slide rail body at two ends of each pulley groove. After the pulleys and the wheel shafts of the pulleys are installed on the sliding rail body, parts of the pulleys located in the pulley grooves are exposed out of the upper surface of the sliding rail body. Compared with a cover with a bottom rail layer and a rail surface layer, only one layer of the sliding rail is needed actually, and the sliding rail is convenient to manufacture, assemble and disassemble. Meanwhile, components are correspondingly reduced, and the principle that the stress structure is thickened from simple under the high-temperature environment in the furnace is met. 本实用新型公开了一种烧结炉内推送装置中的滑轨，包括等静压石墨材料制作的滑轨本体，在滑轨本体
