摘要： PROBLEM TO BE SOLVED: To automatically start rolling of a billet delivered from the twin drum for cooling after the dummy sheet passes, without imposing unreasonable load on the inline mill. SOLUTION: Before a dummy sheet attached to the leading end of a billet 2 delivered from twin drums 1 passes through an inline mill 3, the roll spacing of the inline mill 3 is widened, and the passing of the dummy sheet is detected by a sheet thickness gauge 16 on the outlet side of the mill and the roll spacing of the inline mill 3 is narrowed to the target position for rolling, thereby making it possible to automatically start the rolling from the point when the leading end portion of the billet reaches the inline mill 3 without imposing unreasonable load on the inline mill 3.

摘要： PROBLEM TO BE SOLVED: To obtain thin cast metal of specified thickness and prevent wear of a side gate refractory by moving a pair of cooling drums symmetrically or asymmetrically against the casting center during casting. SOLUTION: A pair of cooling drums 1 and 1' are provided independently wit reduction by a constant pressure by means of a reduction position changing device 5 and a hydraulic cylinder 6 installed via the bearings 4 and 4' of both ends of them. This makes it possible to operate the cooling drums 1 and 1' independently, give independent pressure, and move the drums symmetrically or asymmetrically right and left against the casting center. During casting, a hydraulic servo valve 9 is controlled with the signal of a reaction force controller 8 in accordance with the difference between the target value and the detection value of the drum reaction force of a reaction force detector 7, and the reduction position is controlled with the hydraulic cylinder 6 so that the drum reaction force will be the target reaction force, and with the signal of a reduction position controller 11' in accordance with the difference between the drum gap target value and the signal of the drum position of a position detector 10, a drum speed controller 13 controls a motor M and controls the drum speed so that the drum position will be the target gap.

摘要： PURPOSE: To provide a control method for a plate thickness by a hot continuous rolling mill by which the plate thickness can be controlled with a few errors even in the case of plural rolling stands. CONSTITUTION: In a control method for a plate thickness by a hot continuous rolling mill with three rolling stands or over, an intermediate plate thickness meter 10 is installed between arbitrary rolling stands before two stands or over from a final rolling stand 15. And, by finding previously a correlation between the deviation of the intermediate plate thickness of the tip part of a rolling stock 11, which is measured by the intermediate plate thickness meter 10 and the deviation of a plate thickness between rolling stands from and after it, the drawing down quantities of respective rolling stands are determined according to a correlation between the deviation of the intermediate plate thickness and the deviation of the plate thickness between the rolling stands from and after the intermediate plate thickness meter 10.

摘要： PURPOSE:To provide a selecting method of a grinding wheel which has an optimum combining rate to accomplish a workability and the minimizing of a scracth cut without depending on a rule of thumb, when variuos sorts of rolls with different hardnesses are ground by the same gringing wheel. CONSTITUTION:In this roll grinding method, a grinding wheel whose strength of the combining member (the anti-breakage strength) is 15 to 25kg/cm , in the hardness (Hv) of a work roll used for the plate rolling 650 to 950, and the grading of the grinding wheel 30 to 80, is used. As a result, generation of a scratch cut can be prevented by using the same grinding wheel without changing the grinding condition, even in the grinding of rolls of different hardnesses. Consequently, an efficient work can be carried out and the grinding capacity is improved.

摘要： PURPOSE:To improve the coiling property of a continuously hot rolled steel strip round a mandrel and remarkably reduce a flaw on the surface of the steel strip, generating caused by the slack of the tip part of the steel strip by pressurizing the vicinity of the tip part of the steel strip to the outer periphery of a mandrel at the time of winding between a first wrapper roll and the last wrapper roll. CONSTITUTION:A steel strip rolled by a rolling mill B, is sent to a winding machine C. A detector 8 in a control unit 9 installed in this way of the winding machine, detects the tip position of the steel strip, and a controller 9 calculates the timing of the beginning of winding on a mandrel 2 matching to the speed of passing through of the strip and others. Projected fluid pressurized to a specific pressure by a pressure unit 7 in advance, synchronizes with a timing calculated by the control unit 9, and is projected from a projecting nozzle 5 built in a wrapper roll apron 4 after passing a projecting unit 6. The tip of the steel strip is pushed against the mandrel 2 by the pressure of the projected fluid, and is coiled round the mandrel 2 without any slack.

摘要： PURPOSE:To improve the quality in plate thickness distribution by arranging the rolling mill capable of roll shifting to a front stage finishing stand and having a specified axial directional shape curve and adjusting the shifting amt. of a rear stage stand based on the front stage roll shifting amt. CONSTITUTION:The work roll opposed to the front stages F1-F2 stands of a finishing stand train is shiftable in the roll axial direction and the work roll and a back-up roll are formed by the curve of the sine wave or phase, etc., with the roll barrel length as one period. The intermediate roll and work roll shiftable in the axial direction are provided on rear stage stands F3-F6 and a work roll bending mechanism is arranged as well. The shift amt. of the stands F1, F2 is decided by an aiming crown (c), plate thickness (h) and rolling load (p) and shifting and finish rolling are performed with securing the crown amt. by the rear stage stands F3-F6. Due to the aiming crown being almost achieved at the front stage the quality in the plate thickness distribution of a product is improved.

摘要： PROBLEM TO BE SOLVED: To provide a method for producing a titanium material where, even if a blooming stage is obviated, its surface properties after hot rolling can be satisfactorily maintained, and to provide a stock for hot rolling.
SOLUTION: The invention is characterized in that at least the surface layer of a face as the rolling face in an ingot is melted and resolidified, and is thereafter hot-rolled. Further, the depth of the melted-resolidified layer in the surface layer is ≥1 mm from the outermost surface of the ingot. Further, the melting of the surface layer is performed by one selected from induction heating, arc heating, plasma heating, electron beam heating and laser heating or in combination with two or more. Further, the melting part is made into a vacuum or an inert gas atmosphere. Further, the ingot cooled at a cooling rate of air cooling or above after heating from a temperature above a β transformation point to a temperature less than a melting point is used.
