鉄板で梱包することが行われていた。Conventionally, in order to prevent the outermost circumference and the innermost circumference of the hot rolled strip coil from becoming unusable due to rust, the hot rolled strip coil is packed with an iron plate.
近年、人件費の上昇のため前記の梱包を行わずに製品
コイルを出荷することも行われ、錆発生による歩止低下
を起こしてしまっている。In recent years, due to an increase in labor cost, product coils are also shipped without the above-mentioned packaging, which causes a decrease in yield due to rust.

する。INDUSTRIAL APPLICABILITY The present invention employs endless rolling in which a roughly rolled steel sheet is joined on the upstream side of a finish rolling mill, continuously hot finish rolled, cut after rolling, and then wound into a coil, thereby packaging by another conventional iron plate. It is an object of the present invention to provide a coil production technology that prevents the production coil from rusting while eliminating the steps.

That is, it is characterized in that the portion connected to the cut portion of the steel sheet is rolled by a finish rolling machine of hot endless rolling to be thinner than the product thickness, and the thin rolled portion is used as a packing material for the steel sheet coil.

のために歩留低下を招来することとはならない。INDUSTRIAL APPLICABILITY The present invention utilizes a hot endless rolling technique in which a finisher is cut by a cutting machine and wound on a winder, and a portion having a length equal to or larger than one coil outer diameter from a cutting portion is finished thin It is based on the principle that if rolled and wound, a thin packing material is wrapped around the outer circumference of the coil, and even if rust occurs in this part, cutting it can reduce the yield slightly. . The present invention, in particular, when the plate thickness after finish rolling is thicker than the cuttable plate thickness of the cutting machine,
When cutting at a high speed with a thin cut portion, the portion that should be cut is used as a packing material due to the irregular thickness, and therefore the yield does not decrease.

The strip 1 is wound up by a winder 6 through a finish rolling mill 2, a downstream cooling facility 4, and a strip high speed cutting machine 5 provided on the outlet side. Further, a hydraulic pressure reduction device 3 having a reduction speed of about 5 mm / sec is installed on the stand of each finish rolling mill.

（板厚16mm）のエンドレス圧延を実施するには、第１表
に示すように、 （ａ）仕上圧延機２の入側の接合設備でバーを接合して
第１表に示す状態で運転する。In order to carry out endless rolling of a welded steel plate with a packing material (sheet thickness: 16 mm) in the equipment arrangement according to the present invention, as shown in Table 1, (a) a bar is used at the joining equipment on the inlet side of the finishing rolling mill 2. Are joined together to operate in the state shown in Table 1.

Rolled as 96mpm, the packing material part thinner than the product is about 15m
I was able to. FIG. 2 is a schematic view of the plate thickness of the rolled portion in this way. The strip 1 advances in the direction of arrow 11 and the plate thickness t of the position 10 to be cut becomes 4 mm, so that the plate thickness T 1 (16 mm) From the length L 1 (about 4.5 m) to a thin wall, and then rolling the thin portion by a length l (about 6 m), then length L 2 (about 4.5 m)
m) and return to plate thickness T 2 (16 mm).
（ｄ）上記の薄肉とした部分の切断位置10をトラッキン

比し、エンドレス圧延ではキャンバを生ずることなく、
部分的に薄肉に圧延することができる。The reason why the endless rolling is particularly used for manufacturing the welded steel plate with packaging material is as follows. That is, in the case of the prior art in which the rolling is performed for each unit coil, the portion of the strip tail end that is to be the packaging material is not subjected to tensile force, so if this portion is thinly rolled, a camber or the like occurs, and therefore the packaging material is Cannot be used effectively as In comparison, endless rolling does not cause camber,
It can be partially rolled to a thin wall.
