この発明は、圧延機において炉から出されたスラブを圧
延ロールまで搬送するのに使用される圧延機におけるス
ラブ搬送装置に関する。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention This invention relates to a slab conveying device in a rolling mill, which is used to convey a slab discharged from a furnace to rolling rolls in a rolling mill.

It is necessary to transport the slab heated in the furnace by rolling rolls. Conventionally, such a slab is transported by using a driving roller as a rolling table connected to a rolling roll, and the slab taken out of the furnace is placed on the driving roller and transported on the table to the rolling roll.

しなければならないという欠点があった。Problems to be Solved by the Invention However, in the slab conveying method described above, especially when a shoe pusher type heating furnace is used as the slab heating furnace, if the slab is on the table, the rolled material will be damaged during reciprocating rolling. For reasons such as getting in the way of the movement of the rolling material, the rolling material had to be taken out of the furnace after rolling was completed and there was no longer any rolled material on the rolling table. As a result, the rolling cycle time becomes longer, causing a decrease in production efficiency. Moreover, since the slab is conveyed to the rolling roll by the drive roller while being placed on the rolling table, there is a great risk of contact defects such as rubbing between the slab and the rolling table. Moreover, since the rolling table must be configured with drive rollers from one end to the other, equipment costs are high, and when the furnace is expanded, the drive rollers must also be extended.
この発明は、かかる技術的背景に鑑みてなされたもので

の圧延に供される。The slab (4) taken out onto the rolling table (2) from the working furnaces (3a) to (3d) is gripped and lifted by the slab gripping section (15) of the slab conveyance truck (6). Since a space is created between the lifted slab (4) and the rolling table (2), the movement of the rolled material during reciprocating rolling is not obstructed by the slab (4), and therefore, even in the middle of rolling. The next slab (4) is taken out of the furnace. The slab (4) gripped and lifted by the slab gripper (15) is preliminarily moved by the rolling rolls (1
), where it is kept on standby, and after rolling is completed, it is subjected to the next rolling process.

し圧延に供する。After lowering, the motor (17) is driven to rotate the ball screw (16) to bring both arms (14) closer together, and the claws (15c) (15c) of the slab gripping part (15) are moved closer together.
are brought into contact with the front and rear end surfaces of the slab. Then the cylinder (
(2) Operate 0) in the opposite direction to raise the slab lifting device (11). Along with this, the arms (14) and (14) also rise, but the gripping parts (15) and (15) are pulled downward by the weight of the slab (4), and the inclined parts (15a) are moved along the rollers (15d). and move relatively inward and diagonally downward. Then, the claws (15c) (15c) at the tips of both grips
) narrows, and the slab (4) is further subjected to force in the biting direction by the claws. In this way, the slab (4) has a claw part (
15c) It is lifted from (15c) under a strong clamping force based on its own weight. The carriage (6) holding the slab (4) moves by itself to the driving roller part of the rolling table (2), and then lowers the slab lifting device (11) to lift the slab (4) onto the rolling table (2). Grate. Then, the arms (14) (14) are moved in the separating direction to release the grip on the slab. Next, the slab (4) is conveyed to the rolling roll (1) by the drive roller of the rolling table (2) and subjected to rolling.
前段のスラブ(4)が往復圧延を施されている途中に、

の前段の圧延材の移動が妨げられることはない。While the slab (4) in the previous stage was being subjected to reciprocating rolling,
The next slab is taken out of the furnace. The slab taken out of the furnace is transferred to the slab lifting device (11) of the slab conveyor (6) in the same manner as described above.
). Since a space is created between the lifted slab (4) and the rolling table (2), movement of the rolled material in the previous stage during rolling is not hindered.
従って、前段の圧延が全て終了するまで炉出しを待つ必
要はなく、圧延途中において次段のスラブの炉出しを行
うことができる。Therefore, there is no need to wait for rolling of the slab in the previous stage until all rolling is completed, and the slab in the next stage can be rolled out during rolling.

ャー式加熱炉においても前段の圧延の終了を待つまでも
なく圧延の途中においてスラブの炉出しが可能となる。Effects of the Invention As described above, the present invention allows the slab to be lifted by the slab conveyor, and in the lifted state does not interfere with the rolling of the slab in the previous stage. The slab can be taken out of the furnace during rolling without having to wait for the end of rolling.
従って、圧延サイクルタイムを短縮することかでき、生
産性の向上を図りうる。Therefore, the rolling cycle time can be shortened and productivity can be improved.
しかもスラブ搬送台車はスラブを持上げた状態でレール
上を自走可能であるから、圧延テーブルを全て駆動ロー
ラにより構成しなくてもスラブを圧延ロールへと搬送す
ることができる。In addition, since the slab conveyance vehicle can move on the rails while lifting the slab, the slab can be conveyed to the rolling rolls even if the rolling table is not entirely composed of drive rollers.
しかもまた、圧延テーブルとスラブとの接触区間を可及
的少なくできるから、スラブに生じる接触紙の危険を減

分を延設する必要がなくなる。Moreover, since the contact area between the rolling table and the slab can be reduced as much as possible, the risk of contact paper occurring on the slab can be reduced. Moreover, since the slab is transported by a transport vehicle as described above, the expensive driving roller part of the rolling table can be eliminated or shortened, and as a result, equipment costs can be reduced and it can also be used when adding a furnace. There is no need to extend the drive roller portion.
