摘要： A method for controlling edge drop in a cold rolling operation adaptable to tandem cold rolling mill stands by shifting a pair of vertically disposed single-end-tapered work rolls along the widthwise direction of a steel strip. The work rolls have tapered end portions that are disposed on the two widthwise ends of the steel strip. Pairs of work rolls are sequentially mounted on one or more stands and a pair of vertically disposed plain rolls are mounted on at least a final stand, wherein cold rolling is performed so that the thickness offset in the widthwise direction of the steel strip is controlled by independently adjusting the position of the single-end-tapered work rolls according to the following steps: measuring the edge drop at each widthwise end of the steel strip on the outlet side of the final stand; calculating the edge drop offset between the measured amount of the edge drop and a target amount of the edge drop on the final stand outlet side; and individually changing the shift position of the vertically disposed single-end-tapered work rolls in accordance with the edge drop offset at the widthwise ends.

摘要： The present invention provides a composite roll for cold rolling capable of rolling a cold-rolled steel strip having little edge drop, a cold-rolled stainless steel strip or a bright finish steel strip having excellent surface brightness or a silicon steel strip excellent in magnetic properties without causing breakage of roll, which is a roll in which a sleeve is fitted at a surrounding of a shaft portion with the shaft portion as a central axis and its fabrication method, in which the sleeve is constituted by previously integrating a plurality of pieces of mold members divided by a face intersecting with the central axis of the roll. Further, this is a fit roll in which a sleeve member of an outermost layer is made of WC—Co series hard alloys having Young's modulus of 35000 kgf/mm or more and Co content of 12-50 weight % and is provided with a wall thickness of 3% or more of roll radius and a ratio L/D of a length L of a barrel of the sleeve to a diameter D of the roll falls in a range of 2-10. Further, when there are one layer or more of intermediate layers between the outermost layer of the sleeve and the shaft core, the intermediate layers are arranged such that Young's modulus of the layer on the outer side is larger than Young's modulus of the layer on the inner side.

摘要： A rolling mill comprises a pair of crown work rolls each having, at both ends of a drum, tapered ends ground at different taper angles, respectively. The work rolls are located one above the other with one tapered end of one work roll being in opposition to one tapered end having a different taper angle of the other work roll. The work rolls are movable in axial directions, such that edges of the plates are rolled by one tapered end of one work roll and a drum of the other work roll, and between tapered ends of both the work rolls. The method and rolling mills are capable of controlling the crown and edge drop reduction and simultaneously preventing local protrusions such as high spots and edge built-up to produce flat rolled plates having no difference in thickness and further capable of controlling the crown and the edge drop according to the material, thickness and width of the plates.

摘要： A method of manufacturing a steel sheet having excellent deep-drawability. A steel blank is rolled into a steel sheet having a predetermined thickness. The steel contains C: not more than 0.008 wt %, Si: not more than 0.5 wt %, Mn: not more than 1.0 wt %, P: not more than 0.15 wt %, S: not more than 0.02 wt %, Al: 0.010 to 0.10 wt %, N: not more than 0.008 wt %, and at least one element selected from the group consisting of Ti and Nb which is contained in an amount satisfying the relationship of 1.2 (C/12+N/14).ltoreq.(Ti/48+Nb/93). In at least one pass, rolling is conducted within a temperatures range lower than the Ar3 transformation point but not lower than 500.degree. C., in such a manner that the roll radius R (mm) and the blank thickness t (mm) before rolling by rolls satisfy the relationships of R.ltoreq.200 and R.sup.2 .times..sqroot.t.ltoreq.100000, and the total rolling reduction at temperature lower than the Ar3 transformation point is not lower than 60%. The hot-rolled steel sheet possesses a high level of Lankford value, and is free from cold-working embrittlement. The method may include the step of obtaining, after the rolling, pickling, annealing and hot dip galvanizing under certain conditions, a surface-treated steel sheet having excellent deep-drawability.
