Abstract: PROBLEM TO BE SOLVED: To provide a method and equipment for treating the surface of a hot rolled metallic strip or a steel sheet which allow to have homogeneous mechanical characteristics ranging over the length and width of the strip. SOLUTION: In the first process, a rolling stock 6 is cooled to a temperature at which generation of scales are limited or restrained ranging over the width and length of the rolling stock homogenously shortly after the last deformation process of the rolling line and, in the second process, according to circumstances weakly scale-generated rolling stock is annealed in the declining atmosphere to completely remove scales on its surface and concurrently to adjust the mechanical characteristics as desired. A coil 7 is unwound with an unwinding device 9 and is fed consecutively into an annealing furnace 8, which comprises a heating zone 13, a holding zone 14, and a cooling zone 15, where de-scaling process and desired organizational adjustment are executed.

Abstract: PROBLEM TO BE SOLVED: To provide a method and a device in which molten metal can be discharged without any slag while evading the molten metal from splashing when the molten metal is tapped off, and the operation can be achieved at low investment and operation cost. SOLUTION: When the molten metal (5) is tapped off, just before the tapping- off process and during the tapping-off process, a fluid blowing jet (25) having high kinetic pulse energy is jetted in parallel to the molten metal surface (7) sufficiently as much as possible through an opening part (4) for tapping off in the melting vessel (1) so that a molten slag (6) is evaded from flowing out from a melting vessel (1) by pushing back the molten slag (6) from the surface of the molten metal (5) in the tapping-off range by a blow-lance (20) provided at the outside of the melting vessel (1) and variable in the inclination to and the distance from the molten metal flowing-out ridge part (10).

Abstract: PROBLEM TO BE SOLVED: To provide a high-speed shear for cutting hot and cold strips capable of accurately cutting even of a thin strip with thickness up to 0.8 mm, for example, at a strip speed of substantially 20/mm. SOLUTION: The high-speed shear transversely cuts the rolling strip with a pair of rotation drivable cutter support bodies facing to each other. The cutter support bodies 1, 1' are supported by one common shear cassette on both sides at a defined interval, and the shear cassette 2 is disposed in the outer frame and provided with a hoisting lift means 4 in the outer frame.

Abstract: PROBLEM TO BE SOLVED: To adapt a water-cooled line, by changing cooling tubes and a guiding member or a guiding trough, to the diameter of various rolling wire rods which differs by changing of cooling tubes. SOLUTION: When rolling wire rods having air thermal refining, a water- cooled device connected forward is formed within the limits of bigger and bigger diameters of the wire rods. In the case of high rolling speed of up to 120 m/s or more, the limit of the diameter of the wire rods cannot be covered with only one cooling tube but should be rather covered with cooling tubes having various diameters to be guided closely and precisely. The whole water- cooled line 1 formed with many cooling tube lines which are set in parallel and which have cooling tubes coupled each other by the guiding trough 3, set in a cooling water box 2 and having different internal diameters is equipped on a carrier structure. When changing the diameter needed in the cooling tube line, the whole water-cooled line 1 is slided in parallel and in the vertical direction for a rolling wire rods guiding line 7.

Abstract: PROBLEM TO BE SOLVED: To provide a high-speed drum shear for steel plate simplified in the structure for synchronizing drums when an accurate position of a cutter is required in cutting. SOLUTION: In this invention related to a high-speed shear for dividing an especially thin rolled steel plate in the cross direction, at least one cutter 7 arranged on two drums 1, 2 facing to each other is provided with a cutting edge, namely, a cutting blade 8, and this cutting blade can be accelerated by the feeding speed of a rolled steel plate 9 to be cut, and the drums are provided with a depressor device separately controllable to a cutting position or an opening and passing position. The drums have teeth formed so as to be engaged with each other for synchronization at an opening position and a closing position and so that the synchronization is secured when a large looseness exists between the drums at the opening position and so that the teeth are practically engaged with each other without generating looseness between the drums at a cutting position.
