摘要： PURPOSE:To improve working ratio of a continuous casting by rapidly charging simple dummy in a mold in belt type continuous casting machine and next starting casting. CONSTITUTION:A simple dummy storing box 20, simple dummy charging guide 21 and driving roll 19 are arranged in the continuous casting device having tension pulleys 2a, 2a'. When the continuous casting is started by pouring molten metal 6, each piece of the simple dummy 18 is pushed out on the guide 21 one by one from the storing box 20. The dummy 18 are clamped with dummy clamp 23 and charged by rotation of the tension pulleys 2a' through driving of a driving roll 19. Then, the short side block 25 is rotated as synchronizing with belts 3a, 3b and the interval between these blocks is changed. By this method, as the dummy 18 is rapidly charged, the casting preparing time is shortened and the working ratio of the continuous casting is improved.

摘要： PROBLEM TO BE SOLVED: To provide a steel material for press-forming and quenching which is superior in fatigue characteristics and has an adequate shape after having been quenched, and to provide a manufacturing method therefor. SOLUTION: The steel material for press-forming and quenching superior in fatigue characteristics includes 0.0002 to 0.0050 mass% B, has a Vickers hardness of 350 or higher in a center of a sheet thickness of the steel material, and has the Vickers hardness of 300 or higher at a position of 40 μm deep from the surface of the steel material. The steel material further has the surface covered with a plated layer. Because of including B, the steel material secures necessary fatigue characteristics even when having low hardness, and can be quenched in an alleviated condition, and specifically be cooled in such a cooling rate as not to deform the steel material during quenching. Because the quenching condition can be adjusted or because the steel material has the surface covered with a plated layer, it can secure the hardness in the vicinity of the surface and improve the fatigue characteristics in comparison with a conventional steel material.

摘要翻译：解决的问题：提供一种疲劳特性优异且淬火后具有适当形状的压制成形淬火用钢材，并提供其制造方法。＆lt; P＆gt;解决方案：疲劳特性优异的压制成形淬火用钢材，含有0.0002〜0.0050质量％的B，钢材的板厚中心的维氏硬度为350以上，维氏在距离钢材表面40μm深的位置处的硬度为300以上。钢材还具有被镀层覆盖的表面。由于含有B，因此即使硬度低，钢材也能够确保必要的疲劳特性，能够在缓和状态下淬火，特别是在淬火时不使钢材变形的冷却速度进行冷却。由于可以调节淬火条件，或者由于钢材的表面被镀层覆盖，所以与以往的钢材相比，可以确保表面附近的硬度，并且提高疲劳特性。版权所有（C）2006，JPO＆NCIPI

摘要： PROBLEM TO BE SOLVED: To dissolve the danger of breaking in a joined part, also to suppress the excessive variation of rolling tension and to improve the stability of operation and thickness accuracy of products by reducing the difference in level in the width direction and width of gap wedge of butt part due to the camber of a material to be rolled. SOLUTION: Side guides 7, 8 are attached on the inlet side and outlet side of a truck 1. The side guides 11, 12 are arranged on the inlet side and outlet side of a cutting machine 10. In the state where camber is straightened, crop is cut and removed and, in the state where a steel sheet is guided with the side guides on the truck, the sheet is clamped and, in the state where the guides are released, butt joining is executed. In this way, the productivity and yield of products are improved.

摘要： PROBLEM TO BE SOLVED: To prevent joining defect and to stabilize operation by arranging a vibration preventing device between a joining truck main body and a joining torch so as to suppress the short cycle vibration of a truck not capable of copying synchronization control in butt-joining a preceding rolled material. SOLUTION: A rail frame 5 is placed on the frame 2 of a joining truck through a vibration preventing device 4 utilizing vibration isolation/vibration proof technology, further, a rail 6 is laid on the frame 5 in the direction orthogonal to a pass line L, that is, in a paper face direction. At the same time, a joining torch 3 is mounted to a child truck having a wheel movable on the rail 6. When joining rolled materials, while the joining truck is run at the same speed as running rolled materials 15, 16 in the pass line L, the child truck 8 on the rail 6 is moved, the butting line between the preceding rolled material 15 and succeeding rolled material 16 is irradiated with a laser beam and arc from the joining torch 3. By this method, copying synchronization control, by which a butting line 17 is detected with a CCD camera, etc., is precisely conducted.
