Abstract

PURPOSE:To efficiently perform the rough rolling of slab in a short rough rolling line by arranging a sizing press for edging slab, roughing mill and coil box successively on the outlet side of a heating furnace. CONSTITUTION:A slab S which is heated to a prescribed temp. in the heating furnace 1 is taken out of the heating furnace 1, edged into a prescribed width with the sizing press 2 for edging slab, reversing rolled several times with the roughing mill 4, made into a metallic band plate P with a prescribed thickness and coiled into a coil with the coil box 5. The coiled metallic band plate is properly uncoiled with the coil box 5 and finishing rolled. Then, the edging quantity of the slab S can be increased, because the slab S is edged with the sizing press 2 for edging slab. Therefore, the interval of the width of slab which is manufactured with a continuous casting machine which is installed on the upstream side of the heating furnace 1 can be enlarged, it requires fewer kinds of slab which is manufactured with the continuous casting machine, the frequency of mold change can be decreased and production efficiency can be improved.

There are those shown in Japanese Patent Publication No. 6759 and Japanese Patent Publication No. 61-3561. Of the facilities shown in the above publication, the former is a large-scale production facility equipped with a sizing press to improve production efficiency, and the latter is a medium-scale production facility equipped with a sizing press to shorten the rough rolling line length. For this purpose, it is equipped with a coil box that winds up roughly rolled metal strips.

長の短いものはないのか現状である。[Problems to be Solved by the Invention] However, the equipment shown in JP-A-53-28759 does not give particular consideration to shortening the rough rolling line, so the length of the rough rolling line becomes long, and The equipment shown in Japanese Patent Publication No. 61-3561 does not give any particular consideration to improving production efficiency.
It is not possible to carry out efficient production. Therefore, at present, there is no conventional hot rough rolling equipment that has good production efficiency and has a short rough rolling line length.

, the coil boxes 5 are sequentially arranged on the outlet side of the heating furnace 1 from the upstream side to the downstream side in the slab feeding direction. Further, on the downstream side of the coil box 5, there is a finishing mill (
(not shown) are arranged.

圧延機へ送られ、仕上圧延される。The slab S heated to a predetermined temperature in the heating furnace 1
It is taken out from the slab, rolled down to a predetermined width by a sizing press 2 for slab width reduction, reverse rolled several times in a rough rolling mill 4 to become a metal strip P of a predetermined thickness, and then rolled into a metal strip P with a coil box 5. wound into a coil. Rolled up metal strip P
is suitably rewound in the coil box 5 and sent to a finishing mill (not shown), where it is finished rolled.

ップが生じないようにする。When the slab S is reverse rolled by the rough rolling mill 4, edge drops occur at both width ends, so the edge drop is performed at both width ends of the slab S by the edger 3, and dog bones are formed at both width ends. This is done to prevent edge drops from occurring on the metal strip P after rough rolling.

上述のように、スラブＳはスラブ幅圧下用サイジングプ
レス２て幅圧下を行うようにしているため、スラブＳの
幅圧下量を大きくできる。As described above, since the width of the slab S is reduced by the sizing press 2 for slab width reduction, the amount of width reduction of the slab S can be increased.

ができる。Therefore, the interval between the plate widths of the slabs produced by the continuous casting machine installed upstream of the heating furnace 1 can be increased, and the number of types of slabs produced by the continuous casting machine can be reduced. Therefore, the degree of opening of the mold in the continuous casting machine may be changed less, and production efficiency can be improved.

グボーンをつぶしてやる。FIG. 2 shows a second embodiment of the present invention, in which a two-high rolling mill 6 is installed between a sizing press 2 for reducing slab width and an edger 3. In this case, if the dogbones generated at both width ends of the slab S or metal strip P whose width has been reduced by the slab width reduction sizing brace 2 or the edger 3 are too large, the dogbones are appropriately removed by the two-high rolling mill 6. I'll crush it.
