摘要： PURPOSE:To eliminate remaining scale on the surface of a pickled steel plate by improving descaling capacity of a dead soft steel plate. CONSTITUTION:In a descaling method for the surface scale of a slab drawn from a heating furnace in a hot rolling line, after moving the slab 3 drawn from the heating furnace 1 back and forth on a table roller 2, the slab is descaled by jetting highly pressured water from a high pressure water spray descaling device 4 and the slab is edged by a sizing press 5. Thus, generation of defective products due to a scale pattern after plating with melted zinc is prevented.

摘要： PURPOSE:To reduce cost required for amploying a device by making the device simple and compact as for the inside cleaning device by which foreign matters remaining in the inside of a steel tube such as a remaining slag of welding is removed. CONSTITUTION:A truck 4 provided with a scraper 11 at its tip end and an operating belt 5 by which the truck is pushed and pulled are carried into a located cylindrical body P so as the foreign matter in the body P to be scraped off by the scraper 11. The operating belt 5 is a group of traveling bodies 13 and a chain by which the bodies 13 are connected with each other and constituted to be bendable only downward from the traveling plane. A traveling frame 3 for the truck 4 and operating belt 5 is provided on a rack 1. Sprocket wheels 24 and 25 by which the chain is driven are provided in the midst and at the rear end on the frame 3. A driving mechanism 2 by which the sprocket wheels 24 and 25 are driven is provided on the rack 1. The belt 5 in a standby state is stored in a guide frame 6 provided below the traveling frame 3.

摘要： PURPOSE:To prevent a blow hole from occurring in a weld bead by removing lubricant attached to the end faces of both side edges of a strip metal through rotary bodies after the whole lower surface of the strip metal is coated by coating rolls with the lubricant in front of a die. CONSTITUTION:The whole lower surface (the surface coming in contact with the die 4) of the strip metal 1 is coated by the coating rolls with the lubricant 2. Then, the lubricant 2 attached to the end faces of both side edges 1a of the strip metal 1 is removed continuously by the rotary bodies 5a. The strip metal 1 is penetrated through the die 4 provided with a taper 4a and molded by butting both side edges 1a against each other from the flat shape to the tubular shape. This butt part 1b is welded by a welding torch to make a metallic welded tube. Since the lubricant can be prevented from melting into the welded bead, a metallic welded tube having a good weld part free from the blow hole in the weld bead can be manufactured.

摘要： PURPOSE:To perform the cutting for scraping by setting it to the necessary minimum by outputting a signal corresponding to a position, depth and length of a flaw, and driving a tool in accordance therewith. CONSTITUTION:A surface flaw of a running wire rod 1 is detected, information related to a flaw detected by a flaw detecting mechanism 4 is outputted as a signal, the signal from the flaw detecting mechanism 4 is received and a scraping mechanism 6 is controlled by a control mechanism 5, and the scraping mechanism 6 rotates a tool 63 in the periphery of the wire rod 1 and positions it on the flaw, moves it forward and backward in the radial direction and allows it to cut only the flaw part. In that case, by an automatic wire rod scraping device constituted so that a signal corresponding to a position, depth and length of the flaw of the wire rod 1 is outputted, and the tool 63 is driven thereby, cutting and elimination of the surface flaw of the wire rod 1 brought to expansion and contraction can be performed by cutting the part of the necessary minimum. Accordingly, it does not occur that a degree of reduction is greatly different as to each part of the wire rod 1, and it is disconnected due to necking, and uniform wire drawing can be executed extending over the overall length.

摘要： PURPOSE:To improve the efficiency in heat exchanging by subjecting the Al or Al alloy material forming the film of good water wettability by a precoating treatment to fin forming by its press working and removing a press oil by heating it after assembling the fin. CONSTITUTION:A fin is formed by executing a press work on the Al or Al alloy material having passed a precoating stage. Then, a press oil is actually removed by heating the fin preferrably at about >=180 deg.C after making it as a heat exchanger by assembling it. With this method the wettability of the material is improved and the hear exchanging efficiency of a product can be improved.
