PURPOSE: A coil box is provided to reduce the temperature difference inside an internal space of the coil box when temporarily storing a hot-rolled steel plate which is roughly rolled in a hot-rolled steel plate manufacturing process in the coil box and heating the same. CONSTITUTION: A coil box(100) functions as a heating furnace and a buffer by coiling and uncoiling a hot-rolled steel plate which is moved in a hot-rolling equipment. An inlet(111) where the hot-rolled steel plate is inserted is formed on one side of a box housing unit(110) and an outlet(113) where the hot-rolled steel plate is discharged is formed on the other side of the box housing unit. First and second drums(115,117) where the hot-rolled steel plate is coiled or uncoiled by the turns are arranged in the inside of the box housing unit. The inner upper and lower parts(110a,110b) of the box housing unit are respectively heated by the upper and lower heating units(120,130). First and second exhaust pipes, where the gas inside the box housing unit is exhausted, are respectively formed in both sides of the box housing unit where the inlet and outlet are formed.

PURPOSE: A wire replacement apparatus and method are provided to reduce the time for wire replacement and repair for a cold-rolling process by changing a plurality of wires with new ones at the same time. CONSTITUTION: A wire replacement apparatus comprises one or more wire guide units(110,120) and a wire feeder unit(150). Wires(41,42) are arranged on the side of a frame(11) of vertical-type looper equipment. The wire guide units guide the progressive direction of the wires being replaced. The wire feeder unit provides the wires to the wire guide units for replacement.
