摘要： PURPOSE:To lay an extracted billet onto the normal extracting position by arranging plural extractors executing rectangular movement and correcting stoppers as possible to advance/retreat at between rolls in extracting roller table and automatically operating the extractors. CONSTITUTION:The extractors 15 and the correcting stoppers 25 are alternately arranged between the extracting rollers 10 arranged at the prescribed interval. Gap size G of billets W conveyed in a furnace main body 1 in the extracting side is measured. At the abnormal time such as the gap size G is smaller than the setting value, a projecting part 17 of the extractor 15 is operated so as to come to lower side of the extracted billet W. Successively, at the time, when the projecting part 17 exceeds a hearth line, the billet is once stopped to receive the extracting billet W with the projecting part 17. As the other way, after turning over the billet to the extracting side, the extractor 15 is reoperated, and after holding the extracted billet W with the inner face of projecting part 17 in the extractor 15 and the correcting stopper, the billet is laid on the extracting roller 10.

摘要： PURPOSE:To heighten the operating efficiency of a crane and the housing effi ciency of the material by providing a housing box in a stacker crane and ena bling the shipping/receiving of the multiple plate-shaped material with one reciprocation of the crane between a shipper-receiver station and a housing warehouse, in an automatic warehouse. CONSTITUTION:The material 16 to be housed is housed in a truck 18 transversely movable to the moving direction of a stacker crane and having a roller 17 provided at the lower of it and hard yokes in front and rear of it. A housing shelf 10 has partitions 19 which prevent the fall of the material 16 and while guide the truck 18 at the time of moving. When the truck 18 is pulled out, a catch plate 29 of a holding device, with the surface covered by the hard rubber having the high wear and abrasion resistance, opens by the width as same as the housing shelf 10 and functions as a guide of the truck 18 and the material 16 and while prevents the flaw and the slip by the self-weight of the material at the time of pinching the material 16. Further, by feeding the compressed air to an air bag, the material is pinched to be held and is lifted by a lifting device 31, and is released from the truck 18 and is moved to the upper of the housing box by a shift device.

摘要： PURPOSE:To stably restrain the bending at the time of cooling a rail under a simple method by executing the cooling of the bottom face of rail under the specific condition at the way of cooling the head top face and head side face of rail heated at austenitic range temp. or higher. CONSTITUTION:The high temp. rail 1 holding heat of austenitic range temp. or higher by heating is charged in the cooling apparatus in the right standing state toward longitudinal and the heat top face temp. is measured by a thermometer 8 to output to a control device 9. Next, the head top face and heat side face of the rail 1 are adjusted, so as to be positioned at a prescribed distance H from nozzles 11, 12 and the cooling is executed by injecting air to the head top part and the head side part of rail 1 from the nozzles 11, 12 by an upper nozzle header. In passing the prescribed time, when pearlite transformation becomes 40-60% by progression of cooling of rail head part, the control device 9 is worked to the adjusting valve 7, to execute the cooling by injecting 1/2-1/5 quantity of the air to the rail head part and, to the bottom part of rail from a lower part nozzle header 3. In this way, the temp. difference between the head part and the bottom part of rail 7 is minimized and cooling with non-deformation is executed.

摘要： PURPOSE:To obtain a railhead having fine structure and excellent in the uniformity of hardness without wear or deform of it by passing heavy weight roohing stock on it or at the curved track, by disposing a cooling device in a position at specific distance from a railhead surface and spraying a refrigerant onto the high-temp. rail through nozzles arranged at specific spaces to carry out cooling. CONSTITUTION:Refrigerant spray nozzles 3 of diameter D pointing toward the head of a high-temp. rail retaining high-temp. heat are provided to a cooling device 2 having a length practically equal to that of the above rail 1 at a space Pn of 10-40mm in the longitudinal direction of the rail 1. This cooling device 2 is provided to a position in which a distance H between the above nozzles 3 and the head surface of the rail 1 satisfies H/D>=5. In this state, a refrigerant from a refrigerant supply pipe 4 is sprayed via the above nozzles 3 onto the high-temp. rail 1 in a stationary state to carry out cooling. By this method, the railhead having fine pearlitic structure all over the rail 1 length and excellent in the uniformity of hardness level can be easily obtained.

摘要： PURPOSE:To improve the interval adjusting efficiency by arranging a plurality of arranging arms onto a common connecting link and arranging said arranging arms through the connecting link and allowing said arms to be engaged in front of a plurality of strip members, in a horizontal transporting device for H-shaped steel. CONSTITUTION:Transported members 16 are transported in a prescribed intervals by a transport conveyor 17 as shown by an alternating dash lines. When the transport by a previously set distance L is detected from the pulse signals, etc., supplied from a pulse signal device installed onto a transport conveyor driving motor, an arranging arm 6 is raised by an advance/retreat device 2, and the conveyor 17 is speed-decelerated. Therefore, the transported member 16 is pushed onto the arranging arm 6. Therefore, the transported members 16 contact the arranging arm 6 and stop, and are arranged at a certain intervals. With such constitution, the interval of a plurality of strip members can be adjusted efficiently.
