Disclosed is a vertical strip accumulator. The vertical strip accumulator includes an inner drum unit having an inner drum; an outer drum unit installed at an outer side of the inner drum unit; a central drum unit installed at an inner side of the inner drum unit; and an input unit configured to carry a skelp supplied from an uncoiler to the outer drum unit. The outer drum unit includes an outer drum configured to selectively rotate forward and reverse; a first power source configured to provide a power to the outer drum; an outer roller installed to the outer drum; and a first control unit connected to the first power source to control the operation of the first power source. The input unit includes a carrying roller provided in contact with the skelp; a second power source configured to supply a power to the carrying roller; and a second control unit connected to the second power source to control the operation of the second power source.

A cold-rolled steel strip manufacturing facility includes: a joining device configured to join a trailing end of a preceding steel strip and a leading end of a following steel strip to form a joined steel strip; a looper configured to store the joined steel strip; a heating device configured to heat a joint portion between the preceding steel strip and the following steel strip over an entire width direction; and a cold rolling mill configured to cold-roll the joined steel strip for which the joint portion was heated by the heating device, wherein the heating device is switchable between an output state and a non-output state, and during a period in which the joint portion passes through the heating device, is switched to the output state.

In a method of producing a grain-oriented electrical steel sheet comprising subjecting a steel slab containing no inhibitor-forming components to hot rolling, cold rolling, primary recrystallization annealing working also as decarburization and to final annealing causing secondary recrystallization after applying an annealing separator on the surface, the final cold rolling for cold rolling the steel sheet to the final thickness uses a warm rolling with a tandem rolling mill at a total rolling reduction of not less than 80% at 150 to 280° C. and is performed by extending a pass line length of the steel sheet between the stands so that T satisfies T≥1.3×L/V, where an distance between the stands is defined as L(m), a speed of the steel sheet passing between the stands is defined as V (mpm), and a pass time during which the steel sheet passes between the stands is defined as T(min).
