摘要： PROBLEM TO BE SOLVED: To mutually join slabs without being adversely affected by excessive tension even when the rigidity of the stab is higher. SOLUTION: After the rear end part of a preceding slab 1 is joined with the tip part of the succeeding slab 2 in flying, at the time of feeding them to a finish rolling mill group 6 and continuously executing hot finish rolling, by lifting table rollers 5 in the feeding process after joining the slabs 1, 2 till the slabs reach the inlet side of the finish rolling mill group 6, the slabs are upward deflected so as to be matched to the table rollers 5. In this way, the generation of excessive tension in the way from the joining region the slabs to reaching the inlet side of the finish rolling mill group 6 is evaded.

摘要： PURPOSE:To improve the width accuracy of a product by varying a timing for the crank angle of the release command and control command of a width adjusting brake corresponding to width rolling reduction. CONSTITUTION:Metallic molds are confronted with each other in a slab longitudinal direction. The plate width rolling reduction of a slab is performed by using a press machine which performs the width rolling reduction of the slab by amplifying the metallic molds in a plate width direction by a crank shaft. At this time, the confronting gap of the position of the metallic molds is width- adjusted corresponding to the width rolling reduction of the slab. The timing for the crank angle of the release command and control command of the width adjusting brake to fix the position of the metallic molds when the rolling reduction is performed is varied corresponding to the width rolling reduction. For example, when width adjusting quantity is high, width adjusting time (crank angle 165-30 deg.) can be sufficiently secured by setting the release command of t,he brake earlier than a conventional time, for example, setting the crank angle at 165 deg.. In this way, the cycle time of press can be stabilized.

摘要： PURPOSE:To obtain a product uniform in size and quality by burying an induction heating means inside a mandrel, which is inserted into the inner coiling space of a sheet bar coil for supporting the bar coil, and thereby preventing temperature from dropping in the inner coiling space of the bar coil due to the mandrel. CONSTITUTION:A mandrel 4 is inserted in the inner coiling space of a bar coil 1 at the time of transfer between positions and the time of coiling of the bar coil. A temperature drop is caused in the inner coiling part of the bar coil 1 by the insertion of the mandrel, and therefore, in order to avoid the adverse effect, the area where the mandrel 4 comes into contact with the bar coil 1 is heated by an induction heating coil 4b. Consequently, the temperature drop is prevented in the inner coiling part of the bar coil, and a satisfactory endless rolling is realized.

摘要： PURPOSE:To stably heat and join slabs by installing plural units of inductors for generating magnetic fields for heating slab ends in a width direction and unifying the phases of the currents to be impressed to the respective inductors. CONSTITUTION:The rear end of the preceding slab 1 and the front end of the succeeding slab 2 are connected to each other by a combination of a heating treatment and pressing treatment. The inverters 7, 7' to be exclusively used are connected by each of the inductors L10, L20 to be used and the phases are so synchronously controlled that the currents of the common-mode pass to these inductors L10, L20, by which the eddy currents L11, L21 induced in the slabs are made into the common-mode and the efficient heating by circumrotating currents is realized. As a result, the slabs are stably joined by controlling the phases of the inductors for generating magnetic fields arranged in plural units in the width direction without degrading heating up efficiency even if the slab width increases.

摘要： PURPOSE:To surely peel an amorphous strip from a cooling roll and to coil the strip without any breakage by pushing a magnetized leader tape to the strip just before peeling point of the amorphous strip stuck to the roll and weakening the stickness between the cooling roll and the strip. CONSTITUTION:The magnetized leader tape 8 is coiled with a coiling reel 11 from a supplying reel 7. By accelerating the coiling reel 11, the magnetized leader tape 8 is synchronized with peripheral speed of the cooling roll 5, and a pushing roll 15 is pushed with a cylinder 16 to push the tape 8 to the roll 3. At the time of supplying the molten steel 1 on the roll 3 by ascending a stopper 4 of a tundish nozzle 3, the molten steel 1 on the roll is rapidly cooled to form the amorphous strip 6 and reach to the lower end part of the roll 5. The strip 6 reached to the lower end part of the cooling roll 5 is pushed with the pushing roll 15 and the stickness to the cooling roll 5 is weakened and the strip is attracted with the magnetized leader tape 8 and separated from the roll 5. The strip 6 attracted to the magnetized leader tape 8 is coiled to the coiling reel 11.

摘要： PURPOSE:To measure the size of a crater automatically and easily by irradiating the surface of a roll with a laser pulse beam, converting the intensity of its reflected light into an electric signal, and regarding a small electric signal as a signal corresponding to a crater part and cutting it off. CONSTITUTION:The laser beam (c) projected on the surface of the roll 3 is photodetected by a photodetector 6. The roll 3 is ground and then irradiated with the laser beam; and the photodetection quantity of the photodetector 6 corresponding to a crater 1 is small although the reflection factor of a flat part 4 is extremely high. Its photodetection signal (d) when a low output signal is cut off by a limiter 7 and becomes a signal (e) with a pattern (c). Then this signal (e) is processed by a waveform shaping circuit 8 to become a signal (f) with a pattern (d). An up counter 10 counts pulses of a pulse signal (b) outputted by an oscillator 5 when the signal (f) becomes zero and the surface shape of the roll 3 is calculated from the counted number of pulses.

摘要： PROBLEM TO BE SOLVED: To eliminate the program errors with perfectness similar to that of a white box test even with a test that has the simplicity similar to that of a black box test by comparing the new input data with the stored data to store the new data if the new data are not coincident with any of stored data and then displaying a series of stored data. SOLUTION: A program storage part 11 stores a program that shows the sequence control procedure. A program output part 12 outputs the stored program to a programmable controller. A data input part 13 inputs the data from the programmable controller. A data storage part 14 stores plural data. Then the new data inputted from the part 13 are compared with each of data stored in the part 14. If the new data are not coincident with any of stored data, these input data are stored in the part 14 and then displayed on a display screen or the paper.

摘要： PROBLEM TO BE SOLVED: To provide an induction heating device heating uniformly and joining slabs regardless of a difference in the width dimensions of the slabs by equipping at least two pairs of inductors along the width direction of a band plate on the induction heating device, and arranging a plate which is a magnetic substance between the inductors. SOLUTION: A plate P made of a magnetic substance is arranged in a gap L formed between adjacent inductors 1a. Consequently, since the plate P becomes a magnetic path, an alternating field applied by the inductors 1a penetrates slabs S1 and S2 in the same way in the gap. Therefore, a temperature increase almost equal to those in the other areas can be expected, and continuous hot rolling with high productivity can be performed.
