摘要： PROBLEM TO BE SOLVED: To easily change the direction with a simple structure without using a complicated control system when the direction of a long conveyed body is changed. SOLUTION: A long conveyed body, e.g. a billet 2, is conveyed in its longitudinal direction by a conveyance table 1, and its tip is turned to the change direction side by the skew action of direction change rollers 6a-6i when the tip of the billet 2 reaches a direction change roller group 6 having the rollers 6a-6i arranged at the terminal end of the conveyance table 1 with the axial direction crossing the conveying direction of the billet 2. When the tip of the billet 2 is restrained in contact with a side guide 11 extended perpendicularly to the conveying direction of the conveyance table 1, for example, the tail end side is largely turned by the turn moment applying action of the conveyance table 1. When the whole billet 2 is mounted on the direction change roller group 6, the billet 2 is carried out by its skew action with the side face in the longitudinal direction guided by the side guide 11.

摘要： PROBLEM TO BE SOLVED: To provide a steel continuous casting method which can profitably prevent the development of channeling in a mold when controlling molten steel supplying quantity into the mold by using a three-layer type slide valve. SOLUTION: This steel continuous casting method is executed by supplying the molten steel held in a tundish into the mold through the slide valve formed with the three-layer plates arranged at the bottom part of the tundish and an immersion nozzle 4 successively arranged with the slide valve. In such a case, as the immersion nozzle in this steel continuous casting method, the immersion nozzle with spouting holes 7 having the spouting hole angle 10 deg. in the reverse direction to the drift of the nozzle spouting flow caused by leaning of the molten steel flow at the flow rate adjusting part of the slide valve, is used.

摘要： PROBLEM TO BE SOLVED: To coil the thin strip in an excellent condition free from any surface flaws by reducing the tension to be given to the thin metal strip by a conveyor using a suction conveyor in which the surface of a belt is coated with the fluoride resin to prevent the breakage due to the excessive tension in advance. SOLUTION: A belt 11 of a conveyor to be circulated at the position close to a suction box 10 performs suction by a suction blower 12 to suck a thin strip 4 on the belt 11 through a suction plate 9 of the suction blower 12 and the belt 11. By coating the fluoride resin such as Teflon, the friction force to be generated between the thin strip 4 and the belt 11 is reduced, and the tension to be given to the thin strip 4 to be carried by the belt 11 is also reduced. Thus, the breakage due to the excessive tension can be prevented in advance.

摘要： PROBLEM TO BE SOLVED: To prevent the winding of a strip around a cooling roll by pushing a belt for conveyor against the surface of the cooling roll and executing the detachment and the conveying of the metallic strip. SOLUTION: The strip 4 is detached from the cooling roll 1 by the air- blowing of an air-nozzle 5 providing a slitting opening hole for blowing gas e.g. compressed air to almost the tangential direction to the roll 1. Then, it is prevented that the detached point P shifts to the upstream side even in the case of strengthening the air blowing of the air-nozzle 5 by pushing the belt 6a of a vacuum suction type conveyor 6 to the position (detaching position P) desirable to detach the strip from the cooling roll 1 so as to contact with the belt 6a. Successively, the strip 4 is sucked to near the starting point of the belt 6a of the vacuum suction type conveyor 6 at the same time of detaching and further, the strip 4 is shifted together with the belt 6a under sucking condition and conveyed to a winding reel arranged at the end part of the conveyor 6 to wind the strip 4 as coil-state.

摘要： PROBLEM TO BE SOLVED: To produce a wide width strip having uniform strip thickness in the width direction by using a nozzle giving the longitudinal direction distribution according to a specific equation. SOLUTION: The wide width metallic strip is produced by injecting molten metal on the surface of a cooling roll during rotating at high speed from the slitting opening hole nozzle extended as slender-state in the axial direction of the roll and rapidly solidifying. Then, the nozzle giving the longitudinal direction distribution according to the equation I related to the gap crossing at the right angle with the longitudinal direction of the slitting opening hole, is used. In the equation I, a (x) is the gap in the distance (x) from the center part of the longitudinal direction of the slitting opening hole (mm), ao is the gap at the center part of the longitudinal direction, tce is the strip thickness at the center part of the metallic strip produced with the nozzle having the gap ao (μm), ted is the strip thickness of the edge parts of the metallic strip (mm), L is the width of the metallic strip (mm), (n) is the constant showing the influential degree of the gap to the strip thickness and strip thickness ∝(slit gap) . By this method, the opening hole shape of the nozzle can be optimized.

摘要： PURPOSE: To surely coil a strip to a reel even in the case of the extremely thin strip by pushing the strip during running at high speed after detaching from cooling rolls rotated at high speed to a reel providing a sucking or sticking means on this barrel surface and at just after this, cutting off with a shearing edge at the downstream side from the contacting point with the reel. CONSTITUTION: After holding molten metal substantially having component composition of an iron at 1300 deg.C, this molten metal is injected onto the copper alloy-made cooling roll rotated at the high speed from a nozzle having 50-250mm width of a slit-state opening hole and made to be the strip 1 having 25μm thickness. This strip 1 is detached from the cooling roll and carried to near the reel 2 with a carrying device and pushed to the reel 2 rotated at the peripheral speed synchronized with the speed of the strip 1 and coating an adhesive material 3 on this barrel surface with a pushing roll 4 rotated the peripheral speed synchronized with the speed of the strip 1 to press-fix the strip 1 to the reel 2, and the coiling is started. Then, a shifting device 6 is lifted to shear the strip 1 with the shearing edge 5.
