本発明は竪形圧延機と横形圧延機とを組合せた
圧延機に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a rolling mill that combines a vertical rolling mill and a horizontal rolling mill.
例えば一定幅に連続鋳造されたスラブを、鋳造
幅圧下圧延し、種々の幅をスラブを得るようにす
ると、連続鋳造機で幅の変更を行う必要がないた
め、連続鋳造機の生産はそれだけ能率よくなる。
この場合に、幅寸法が鋳造幅より非常に小さいス
ラブを製造するには、幅圧下圧延を速パスさせて
行う必要があることは当然である。 For example, if a slab that has been continuously cast to a constant width is rolled to reduce the casting width to obtain slabs of various widths, there is no need to change the width in the continuous casting machine, and the production efficiency of the continuous casting machine becomes that much more efficient. get well.
In this case, in order to manufacture a slab whose width dimension is much smaller than the casting width, it is natural that width reduction rolling must be performed in a fast pass.
しかし、幅方向の圧延のみでは、スラブの幅方
向端部がドツグボーンと称する盛上り形状となつ
てしまうため、水平ロールを用いたスラブ厚さ方
向の圧延を行つて前記ドツグボーンを殺してやる
必要がある。 However, if only the rolling in the width direction is carried out, the ends of the slab in the width direction become raised in shape called dog bones, so it is necessary to roll the slab in the thickness direction using horizontal rolls to kill the dog bones. .
そのために、竪ロールを用いた竪形圧延機と水
平ロールを用いた横形圧延機をパスラインに沿い
何台か並べる形式の圧延設備が採用されている。 For this purpose, rolling equipment is used in which several vertical rolling mills using vertical rolls and several horizontal rolling mills using horizontal rolls are arranged along a pass line.
しかし、このような竪形圧延機と横形圧延機を
組合せた圧延機では、従来のユニバーサル分塊圧

値どおりにならないところから、圧延機の速度同
期を正確に行うことが困難であるが、速度同期が
正確に行われない場合には、竪形及び横形の圧延
機同志がモータトルクによつて大きな力で引合つ
たり押合つたりしている。 However, in a rolling mill that combines a vertical rolling mill and a horizontal rolling mill, the slippage of the material during rolling does not occur as expected, as seen in conventional universal blooming mills. It is difficult to perform speed synchronization accurately, but if speed synchronization is not performed accurately, vertical and horizontal rolling mills may be pulled or pushed together with large force due to motor torque. There is.

ルである。 In order to transmit this large force, conventionally, as shown in Fig. 1 as an example of a combination of a vertical rolling mill, a horizontal rolling mill, and a vertical rolling mill, a vertical rolling mill housing a and a horizontal rolling mill housing are used. b to bolt c
Alternatively, it is tightened with a key or the like to absorb the above-mentioned large force. In the figure, d is a vertical roll, e is a horizontal roll, f is a vertical roll drive device, and g is a spindle.

くなり、その結果他の各部にもガタが生じ、大事
故につながるという大きな問題がある。 However, if the rolling mills are repeatedly pulled together or pushed together with great force, both rolling mills will be shaken and vibrated. Since f is installed on the vertical rolling mill housing a, the vibrations and load fluctuations due to the rotation of the vertical roll drive device f are added to the vibrations described above, and the entire machine is shaken and vibrates with an even greater force. As a result, repeated large impacts are applied to the fastening parts and keys of the machine, causing significant wear and tear, which in turn causes rattling in other parts, leading to serious accidents.

It is characterized by being placed on a pedestal separately provided.
