摘要： PURPOSE:To prevent the deep intrusion of inclusion involved into molten steel stream and bubbles of argon, etc., into the inner part of a slab by executing electromagnetic stirring to the molten steel in such an arrangement that each magnetic pole of coils of an electromagnetic stirring device is reverse polarity to each other for the coils facing across a casting mold, while the pole is the same polarity to each other for the coils placed side by side. CONSTITUTION:In the coils (a), a'-(d), d' in the electromagnetic stirring device, two- phase power units composed of transformers 3a-3d and cyclo-converters 4a-4b of two phases (u-phase, v-phase) are wired in each of the coils (a), a', coils (b), b', coils (c), c' and coils (d), d', and on the other hand, in the cyclo-converters 4a, 4b, one set of a frequency setting device 5 is wired. Then, the winding structure of the coils (a), a'-(d), d' is that iron cores constituting four poles is used and u-phase wire winding is executed so that the poles at the upper most step and the pole at the third step become the reverse polarity in the coils (a), a'-(b), b' and the pole at the upper most step and at the third step in the inside coils (a) and (b) or the outside coils a' and b' become the same polarity and also the pole at the upper most step and at the third step across which the inside coils (a), (b) and the outside coils a', b' opposite to each other become the reverse polarity.

摘要： PURPOSE:To facilitate the handling of a wire rod coil by adjusting the speeds of the upper stream and lower stream rolling mills and leaving a proper interval between a preceding wire rod and succeeding wire rod, after the cutting of the wire rod by a flying shear. CONSTITUTION:A wire rod 3 is cut by the flying shear 4 located between a roughing mill train 2 and intermediate rolling mill train 5. The roughing mill train 2 is decelerated, a relative speeds difference V is given to a preceding wire rod 3a and succeeding wire rod 3b to leave a proper interval (d) between the both. At the time when the tip of the succeeding wire rod 3b reaches the next rolling stand ST9, the rolling speed of the roughing mill train 2 is accelerated so that its rolling speed is synchronized with the rolling speed of the rolling stand ST9. The space between cut wire rod coils is surely separated an the wire rod coil can easily be handled without having a special function at a coil collector part.

摘要： PURPOSE:To reduce energy cost in heating and rolling section by adjusting billet ejecting temp. so that the sum of used power cost for rolling mill and fuel cost for heating furnace comes to the min. CONSTITUTION:The heating furnace DDC2 receives the lower limit value t1 and the upper limit value t2 in tolerance of the ejecting temp. from a process computer 1 and an ejecting temp. setting changing means 2b sets the setting value (t) of the ejecting temp. for the heating furnace 3 to t1. By command of a main machinery DDC4, the rolling mill line 5 executes rolling of a little quantity of the billets, to measure loaded power of a motor for rolling, and the power cost is calculated with a power cost calculating means 4a. This calculated cost value is transmitted to the heating furnace DDC2, and heating roll energy cost calculating means 2a adds data of the used fuel cost for the heating furnace from the computer 1 to calculate the heating roll energy cost. Successively, the ejecting temp. setting changing means 2b changes the ejecting temp. setting value (t) to t1+ t and in case (t) exceeds t2, the ejecting temp. setting value tm at the rolling time having the lowest heating roll energy cost in every rolling times, which have ever been executed, is set and after that, the rolling is executed.

摘要： PURPOSE:To easily calibrate the installing location of a one-dimensional line sensor at the job site so as to accurately measure the surface temperature and surface temperature distribution in the width direction of a high-temperature moving material, such as a cast piece being drawn by continuous casting or a steel sheet, steel plate, etc., being rolled in a hot rolling process. CONSTITUTION:The title instrument is provided with a position adjusting mechanism which can perform fine adjustment on the direction of the temperature measuring surface of a one-dimensional line sensor 13 against the opening 14a of a purge feed 14 on a cast piece side from a remote area and kanthal wire 16 which can emit light at a temperature equal to or higher than a prescribed temperature over the full width of a visual field to be measured and is interposed between the opening 14a in the purge feed 14 and temperature measuring surface of the camera 13. At the time of calibration, the camera 13 is made to continue temperature measurement while the wire 16 is made to emit light and the position of the camera 13 is modified to such a position that the mechanism 15 can obtain temperature-measured results over the full width of the visual field to be measured.

摘要： PURPOSE:To automatically detect water cooling nozzles to cool hot rolled steel being clogged. CONSTITUTION:A sensor unit 2 on which pressure sensors 2a are arranged at the same interval as that of the water cooling nozzles is fitted with setting to the punched hole parts of a carrier plate, injected water pressure injected from the water cooling nozzles is detected by the pressure sensor 2a, this is stored in a memory 3c and contents of the stored pressure are stored in an IC card 3d. After the carrier plate passes through an injection water cooling area, the stored contents of the IC card 3d taken out of the memory 3c are operated by a personal computer 5 to be converted into an information signal and outputted. In this way, since a waveform indicating variation of pressure is obtained, how the water cooling nozzles are clogged can be detected by the height of this waveform.
