摘要： PURPOSE:To adjust glossiness independently by tracking the finishing point in the front stage pass and making the starting point of a shift of each work roll in the rear stage pass and overlaying shift parts by the front stage pass when the work rolls is shifted over the total length of the plate material. CONSTITUTION:In formation each stand speed controller 5 is inputted into a tracking arithmetic unit 6, a shift command in a tracking time calculated there is inputted into an operation mechanism 2 and the work roll l is operated by it and shifted. Then, when a position of the plate material which leave No.1 stand and are not shifted arrives No.2 stand, the shift operating mechanism 2 is operated to begin shifting of the work roll 1. Further, in No.3 stand, the work roll 1 begins shifting at the timing when the shift positions arrive at No.1 and No.2. In this way, uniform glossiness is formed all over the length.

摘要： PURPOSE:To prevent the fluctuation of plate thickness and tension in the longitudinal direction caused by a roll shift in the rolling for adjusting the amount of crown of a plate edge by shifting single trapezoidal work rolls. CONSTITUTION:When a metallic material is rolled as the work rolls are arranged to be opposed to each other in the vertical positions in the respective axial directions, one of the rolling speed and the surface roughness of the roll is rolled by the shifting speed in an axial direction decided as a control factor. The dull-finished work rolls where the surface roughness capable of erasing scratches when the ground surface exceeds 0.5muRa are used as the work rolls arranged to be opposed to each other in the vertical positions, high viscous rolling oil where the viscosity at 40 deg.C exceeds 150cSt is applied to this and rolled by the shifting speed in the axial direction deciding at least one of the rolling speed and the surface roughness of the roll as the control factor. High viscous rolling oil is applied as emulsion when it is contained by 1-25% in the water.

摘要： PROBLEM TO BE SOLVED: To restrain the variation of quality caused by the variation of production condition and secure a constant quality by resetting annealing condition corresponding to a product specification according to molten steel components and rolling actual result measured at the intermediate time in a blooming process. SOLUTION: A production specification and a procedure based on a production plan of a cold-rolled steel plate are stored in a production indication storing means 11. Temp., profile and surface roughness, etc., at the time of each rolling are stored in a hot-rolling actual result storing means 21 and a cold-rolled actual result storing means 22. The chemical components are measured by sampling molten steel near solidifying of the intermediate product in the product blooming process 17 and these values are stored in a molten steel component storing means 12. Each of the data from each of these storing means 11, 12, 21, 22 and an annealing means 15 is inputted in an annealing condition setting means 13, and a temp. correction, etc., for preventing the burning is executed by refering to the annealing condition pre-classified in each molten steel component corresponding to the product specification in each hierarchy based on these data. By this method, the resetting of the production specification and the procedure in the production indication storing means 11 is executed.

摘要： PURPOSE:To prevent the occurrence of cracking when a highly brittle material is passed through in a rolling method with continuous cold rolling mill having a slide preventing guide using of intermesh rolls. CONSTITUTION:In this rolling method of a strip of steel sheet, the slide preventing guide 2 having a structure that consists of plural rolls and the underside of at least one roll 21 is situated in the lower part of the pass plane is arranged on the inlet side of a 1st stand of the continuous cold rolling mill for strips which consists of plural stands. An intermesh amount control mechanism 4 is provided and the intermesh amount is changed in accordance with the changing part of the shape of the passing strip while maintaining the force of constraint to the passing strip below the critical buckling force by changing the intermesh amount for every material. Since the intermesh amount is adjusted in accordance with the changing part of the shape in a degree that the force of constraint below the backling of the rolling mill is not eliminated, sliding is prevented, also bending stress by the intermesh is reduced and breaking is prevented.

SOLUTION: This method is a cold rolling method for rolling a metal plate 11 into a desired thickness with the cold rolling mill 15 while pickling the plate in a pickling tank 13 and a thickness measuring meter 17 is provided at a distance of not less than a prescribed metal plate stoppable length S1 obtained by v /(2.α0 ) along the metal plate 11 from the inlet of the cold rolling mill 15 to the side of the pickling tank 13 on the outlet side of the pickling tank 13. Thus, the thickness of the metal plate 11 which is passed through the thickness measuring meter 17 is measured and, and by detecting the variation in thickness due to overpickling, the cold rolling mill 15 is controlled. Where, (v) is the transporting speed (m/min) of the metal plate 11 and a o is the reduction rate (m/min ) of the metal plate 11.

摘要： PURPOSE:To prevent the damage to the surface flaw of a rolling material by confirming the generation of the roll flaw in a rolling time and its position of a stand in the direction of the roll axis through a flaw detector, repeating the shifts of the work roll when this roll flaw is positioned in the plate way and removing the surface flaw. CONSTITUTION:The direction of the ground traces of the surface flaw of the roll is shifted from the rolling direction by shifting the work roll 1. The ground traces of the work roll 1 crush the projectives on the surface flaw through this shift, as a result, the roll flaw generated on the surface of the rolling material P can be gradated by this. The projectives of the ground traces on the work roll are crushed by the friction with the middle roll or the backup roll and this, too, acts on the reduction of the surface flaw. When the surface flaw occurs on the edge part of the rolling material P, the flaw part is pushed out by shifting the work roll to the external part of the plate way to prevent the damage. In this way, the roll flaw on the surface of rolling material can be pushed out to the external part of the roll width to prevent the damage.

摘要： PURPOSE:To diagnose abnormalities of a plate thickness sensor, a plate speed sensor in a real time by obtaining a signal as an area speed given by multiplying the output of the plate thickness sensor by the output of the plate speed sensor. CONSTITUTION:In a tandem rolling mill having the plate thickness sensor 3 and the plate speed sensor 4 in each rolling stand 1, the area speed is obtained by multiplying the output of the plate thickness sensor 3 by the output of the plate speed sensor 4 through a multiplier 5 on the outlet side of the stand. Exact diagnosis is performed by an area speed difference integrated value calculated in two continuous rolling stands and a comparison value.
