Description
圧延鋼を水平方向へ移送するローラコンベヤと、
圧延鋼の搬入口及び排出口を有し、前記ローラコンベヤ上で搬入口から移送されてくる圧延鋼を包囲するように研掃室を内部に規定する包囲体と、
この包囲体に装着され、前記研掃室内の圧延鋼を研掃するようにその圧延鋼に向けて砥粒を投射する少なくとも一つ以上の投射機と、
圧縮エアを噴射して前記研掃室内の圧延鋼上の砥粒を吹き落とす砥粒吹き落とし手段と、
前記投射機によって投射された砥粒と、前記砥粒吹き落とし手段によって吹き落とされた砥粒とを前記研掃室内で回収した後、その回収された砥粒から不純物を除去して前記投射機へ送り込む砥粒回帰手段と、を備え、
前記研掃室内で研掃された圧延鋼は前記ローラコンベヤ上で前記排出口から排出される。
砥粒吹き落とし手段は、好ましくは、送風機と、この送風機の吐出口に伸縮ダクトを介して連通接続しかつ圧縮エアを貯留するエア貯留箱と、このエア貯留箱の下端に形成されて圧延鋼の移送方向とは反対の方向へ35~55度の入射角度で圧延鋼に圧縮エアを噴射するノズルとを備える。この場合、予め、砥粒吹き落とし手段のノズルの高さを圧延鋼の高さまたは厚さに対応して調節したのち、そのノズルから圧縮エアを噴射する。
なお、本明細書において、用語「入射角度」とは、圧延鋼へ吹き付けられる圧縮エア流又は投射される砥粒流の中心軸を圧延鋼に入射する光線に例えた場合に、圧延鋼に対する圧縮エア流又は砥粒流の入射角度である。用語「反射角度」とは、圧延鋼から反射する圧縮エアの中心軸を圧延鋼から反射する光線に例えた場合に、圧延鋼からの圧縮エアの反射角度である。
図1および図2に示すように、本発明の圧延鋼用研掃設備は、圧延鋼を水平方向へ移送するローラコンベヤ1と、ローラコンベヤ1上で移送されてくる圧延鋼を包囲するように研掃室を内部に規定するキャビネット(包囲体)2と、キャビネット2に装着されて圧延鋼に向けて砥粒を投射する複数台の遠心式砥粒投射装置(投射機)3・4と、圧縮エアを噴射して圧延鋼上の砥粒を吹き落とす砥粒吹き落とし装置(砥粒吹き落とし手段)5と、遠心式砥粒投射装置3によって投射された砥粒と、砥粒吹き落とし装置5によって圧延鋼上から吹き落とされた砥粒とを回収したのち、その回収された砥粒から不純物を除去して遠心式砥粒投射装置3・4に送り込む砥粒回帰機構(砥粒回帰手段)6と、で構成してある。
キャビネット2には、ローラコンベヤ1上で水平方向に移送されてくる圧延鋼を研掃室内へ受け入れる搬入口(図示せず)と、研掃後の圧延鋼をローラコンベヤ1上で移送して研掃室から排出する排出口(図示せず)とが設けられている。
本実施形態において、圧延鋼に向けて砥粒を投射する投射機は、一例として、遠心力を利用して砥粒を投射する遠心式砥粒投射装置3・4を用いているが、本発明の圧延鋼用研掃設備に用いられる投射機はそれに限定されるものではない。また、本実施形態における投射機は、複数台としているが、所望により一台としてもよい。
圧縮エアの入射角度が35度未満では、圧延鋼から反射した砥粒が、ノズル9からの圧縮エアによって吹き上げられた砥粒を回収するための砥粒回収機構22のスクリュコンベア24に達せず、その手前に留まってしまうので、この砥粒を回収することができない。また、圧縮エアの入射角度が55度よりも大きいと、圧延鋼に当たって反射した砥粒は上方へ吹き上がるのみであり、この場合も砥粒がスクリュコンベア24へ向かわないので、砥粒を回収することができない。
研掃された鋼板Wはローラコンベア1により移送されて排出口を通じてキャビネット2内の研掃室から排出される。
以上、本発明の圧延鋼用研掃設備について、特定の鋼板Wの具体的な寸法及びそれに投射される砥粒の具体的な投射量を参照して説明した。しかしながら、これらは本発明の説明を容易にする意図で示した過ぎず、本発明の範囲を制限するものではないことに留意されたい。同様に、添付図面に示された本発明の各構成要素は、本発明の要旨の説明のために図示したものであって、図示したものに限定する意図はなく、それらの均等物の使用も本発明の範囲内にあることに留意されたい。
当業者には、特許請求の範囲に記載された本発明の要旨と目的を逸脱することなく、様々な変更例や変形例をなし得るであろう。
