Therefore, the design can effectively prevent tooth skipping, and avoid fluctuation of the conveying surface of a conveying network chain in the conveying process, so that the conveying effect is effectively improved, and the service life ofthe whole system is also prolonged.

The production method for an aligned ceramic sintered body according to the present invention comprises: (a) a step for producing a ceramic molded article before firing the ceramic molded article intothe aligned ceramic sintered body; and (b) a step for sandwiching the ceramic molded article between a pair of release sheets, placing the sandwiched ceramic molded article in a hot-press firing furnace, and hot-press firing the ceramic molded article while applying pressure on the ceramic molded article through the pair of release sheets by using a pair of punches, to obtain the aligned ceramicsintered body. When each of the release sheets is sandwiched by PET films having a thickness of 75 [mu]m and an arithmetic mean surface roughness Ra of 0.03 [mu]m, is mounted on a stainless steel sheet having a thickness of 10 mm and an arithmetic mean surface roughness Ra of 0.29 [mu]m, is vacuum-packed, and is isostatically pressed at 200 kg / cm2, the surface of the release sheet on the oppositeside of the stainless steel sheet has a cross-sectional curve having a greatest cross-sectional height Pt of 0.8 [mu]m or less.

The invention discloses a tungsten rod welding device based on the screw connecting technology. The tungsten rod welding device comprises guide rails. The two guide rails are arranged left and right.A T-shaped sliding block is arranged at the front end of the middle of a connecting pipe. Sliding grooves in cooperation connection with the sliding block are formed in the rear ends of the guide rails. Tungsten rods are arranged in the guide rails and penetrate corresponding heaters and electrode seats. The contact ends of the two tungsten rods are connected through an electrode clamp. The tungsten rods are placed between two press plates from the front side, due to the fact that two upper threaded rods are connected through the same spring, the extrusion force of the press plates to the tungsten rods is constant, and too large pressure cannot be generated; if the two press plates slide on the tungsten rods, even though the tungsten rods are bent, the diameter of each tungsten rod is basically unchanged, and therefore even though sliding happens, the force between the two press plates cannot be changed; the manner is different from common spring extrusion, the force is guaranteed, meanwhile, the tungsten rods can be moved by pushing a handle, ascending and descending cannot be generated, and greater safety is achieved; and the extrusion force can be adjusted through a rotating handle.
