摘要： PURPOSE:To make uniform the sheet width of a final product with high accuracy and to improve yield by adding the spread which arises when the fluctuation of the sheet thickness is removed to the fluctuation of a sheet width in the stage of adjusting the vertical roll gap of a rolling installation provided with vertical and horizontal rolls with the sheet width fluctuation. CONSTITUTION:A material 6 to be rolled is subjected to thickness and cross rolling by the horizontal rolls 1, 2 and vertical rolls 3, 4 of stands 10, 11. A width detector 5 on the outlet side of the stand 10 measures continuously the width of the material 6. On the other hand, the fluctuation of the sheet width is determined by using the rolling load of the roll 1 measured actually by a load cell 1a and the temp. of the material 6 measured by a radiation thermometer, etc. The fluctuation of the sheet thickness is removed by AGC and is flattened but the spread arises in the part where the thickness is large. The spread is added to the width fluctuation outputted by the detector 5 and the correction rate of the gap of the roll 4 required for correcting the total sheet width fluctuation is calculated and is inputted to a tracking device 8. The above-mentioned correction rate for the width fluctuating part is taken out of the device 8 and the roll 4 gap is corrected accordingly when the width and thickness measuring part of the material 6 moves to the roll 4.

摘要： PURPOSE:To obtain a steel strip uniform in thickness and completely free from variation of rolling reaction and variation of plate thickness by joining and rolling the tail end of a front rolled stock having nearly the same width and the tip of a rear rolled member in a joined and welded state. CONSTITUTION:When the tail end of the narrow slab 9 of a front rolled member and the tip of the wide slab 10 of a rear rolled member are joined, the tail end of the front rolled member and the tip of the rear rolled member are equalized in width and joined. For this purpose, after the slab extracted from a heating furnace is pressed by a sizing press 2 being a widening press-down device into nearly the same slab width as the front slab width, the front rolled member being a sheet bar 4 rough-rolled by a rough mill 3 is nearly as uniform as the front rolled member in width. After it is joined with the rear rolled member 11, it is made by a finishing mill 7 into a rolled strip and wound by a take-up machine 8 into a coil. Consequently, the strip whose thickness, also, is not changed at all is obtained.

摘要： PURPOSE:To perform the heat insulation of a high temp. carrier body in uniform temp. distribution by changing the inner face of a heat insulation cover from a low radiation surface to high radiation surface in order according to the carrier movement in the method to keep the warmth of the high temp. carrier body with a heat insulator cover. CONSTITUTION:The heat insulating cover is composed by arranging in a row that which is rotatable centering around a shaft 4 with an insulating material 2 as the core, with one face as the low radiation surface 1 and with other face as the high radiation surface 3. The low radiation surface 1 is directed for the inner side for stand by prior to the high temp. carrier body 5 being transferred. When the high temp. carrier body 5 is conveyed via a roller 6, the heat insulation is performed by directing the low radiation surface 1 to the tip part thereof. The inner face of the heat insulation cover is changed to the high radiation surface 3 in order according to the progress of the center part having high temp. The change is unnecessary for the rear end part with the high radiation surface 3 as it is.

摘要： PURPOSE:To eliminate the variation of width at the time of passing a sheet through a finishing mil by adjusting the width of materials at the time of continuous rolling same as that of a preceding material with a heavy-duty screw down equipment before joining. CONSTITUTION:In the continuous hot rolling in which a bar joining device is arranged between the finishing mill and the heavy-duty screw down equipment in a hot rolling stage, at the time of continuously rolling the materials having different width, the materials are bitten into the finishing mill after changing into a constant width through the heavy-duty screw down equipment by on-line appropriating an order. By eliminating the variance of width that is generated at the time of continuous rolling, the generation of defective part is prevented, also the passing property of the finishing mill group is stabilized and productivity is improved.

摘要： PURPOSE:To reduce a useless time in rolling of a strip by arranging zigzag belts rotatable through shafts and equipping a cooling device between the respective belts. CONSTITUTION:Plural rotatable belts 10 are arranged zigzag with rollers 8 as axes between a finishing mill and a coiler in a hot rolling stage. A lot of cooling devices 9 are equipped between the belts arranged zigzag. A steel sheet runs on these belts. At this time, water is jetted from cooling nozzles of the cooling device 9 set between the belts arranged zigzag to cool a hot strip. In this way, since the strip runs on the belts 10, the roll pitch is eliminated, therefore, the passing speed can greatly be increased and the productivity is improved remarkably.

摘要： PROBLEM TO BE SOLVED: To easily discover flaws on the surface of a slab, and to prevent degradation of the surface quality of a sheet product caused by the surface defect of the slab by providing a pickling equipment between a casting device to cast the slab and a hot rolling mill to roll the slab. SOLUTION: A slab 1 is pickled in a pickling tank 3, and then, the surface of the slab 1 is observed after the cleaning in water, and hot rolled preferably after removing defects of a surface layer. The slab 1 is charged in the pickling tank 3, the pickling tank 3 is covered by a cover 5, and the slab 1 is pickled one by one in a batch pickling equipment. Hydrochloric acid is fed from a hydrochloric acid tank 6 in the pickling tank 3 to pickle the slab 1. After the pickling, the hydrochloric acid is discharged into a discharged weak acid storage tank 7. Cleaning water is fed into the pickling tank 3 from a cleaning water tank 8 to clean the slab 1. Hume to be generated during the pickling is fed to an exhaust cleaning tower 9 and cleaned, and discharged into the atmosphere. Since scales are removed from the surface of the slab 1, flaws on the surface of the slab can easily be found.

摘要： PURPOSE:To set each phosphor wood on a stacking steel plate as specified, by lifting each one after being placed on a lifting block, and pinching the sidepiece. CONSTITUTION:Three pieces of phosphor wood (a-c) existing in a lowermost position in a phosphor wood housing tower A are extruded in a horizontal direction and toward a stacking steel plate with a reciprocation operating part 5 of an extruding mechanism B operated. And, each phosphor wood is conveyed in each interspace among partition plates 7, 7... by a conveyor belt 6, and comes into contact with each stopper plate of a phosphor wood stop housing member H of an orthogonal forward mechanism D whereby it comes to stop. Next, each phosphor wood stop housing member H is advanced in a direction where it orthogonalized with the conveyor belt 6 by respective driving devices of the orthogonal forward mechanism D and each individual phosphor wood is placed on a lifting block 18. Then, this lifting block 18 is made to go up, and each phosphor wood is pinched by a phosphor wood pinching mechanism F, thus they are placed on the stacking steel plate G. Therefore, a bottom surface of each phosphor wood pinched is positioned in the same plane so that it is placeable as scheduled.
