Example Embodiment

[0087] The function of the cold-rolled material manufacturing facility and the cold-rolling method of the embodiment of the present invention will be described below.

[0088] The rolling speed of the leading end of the preceding coil and the leading end of the following coil during joining is lower than the normal rolling speed, and the strip storage length of the strip storage device arranged between the joining device and the rolling mill is shortened , The device is miniaturized.

[0089] Under low-speed rolling conditions, the plate thickness is measured by a plate thickness gauge installed on the exit side of the rolling mill, and the plate thickness is corrected based on the deviation between the plate thickness command value and the actual plate thickness value. Right below the work roll, the time from rolling to the thickness detection is delayed, and the thickness control accuracy is reduced. Therefore, under low-speed rolling conditions, the incoming side rolling speed,...

Abstract

In a cold rolled material production equipment, a strip storage device (50) is provided. The strip storage device (50) is disposed between connection means (23) and rolling machines (10a, 10b). The connection means (23) connects the tail end of a preceding coil (25b), disposed on the exit-side of an unwinding device (21a) for unwinding a hot rolled coil after pickling, to the leading end of a following coil (22a) unwound from the unwinding device. The strip storage device (50) stores a strip S for continuously carrying out rolling by the rolling machines during the connection of the precedingcoil to the following coil by the connection means. The rolling machines (10a, 10b) roll the preceding and following coils, in such a state that the tail end of a preceding coil (25b) has been connected to the leading end of a following coil (22a), unidirectly in a continuous manner. The cold rolled material production equipment further comprises a strip cutting device (28) for cutting the strip into desired length, a winding device (24) for winding the rolled coil, transfer means (30) for transferring the coil extracted from the winding device to unwinding devices (21a, 21b) for repeatedly rolling the coil until the product sheet reaches a desired thickness, and a rolling speed control unit (40) for controlling the rolling speed during connection of the preceding coil to the following coil so that the rolling speed is lower than the steady rolling speed.

Description

technical field [0001] The invention relates to a cold rolling material manufacturing equipment and a cold rolling method. Background technique [0002] As equipment for mass production of cold-rolled materials with an annual output of 1.2 million to 1.5 million tons or more, tandem cold-rolling mill (tandem mill) equipment with more than three cold-rolling mills arranged, or in tandem The tandem continuous cold rolling mill equipment (hereinafter referred to as TCM equipment) that is equipped with a joining device and a strip storage device on the entry side of the cold rolling mill equipment and continuously rolls without stopping rolling is being developed. Practical. In addition, in this TCM facility, a tandem continuous pickling cold rolling mill facility (hereinafter, referred to as PL-TCM facility) is being put into practical use, which is arranged between the joining device and the strip storage device to remove the heat Pickling equipment for the scale of the roll...
