Claims (9)
- 相前後して配置された複数の圧延スタンドを有する圧延ラインであって、前記圧延スタンドが、少なくとも2つのロールより成っていて、これらのロール間に1つのロールギャプが形成されており、少なくとも1つの圧延スタンドのロールに超音波検査ヘッドが対応配置されていて、これらの超音波検査ヘッドは、ロール体の部分が、ロールギャップ内で検査しようとする圧延品に達する超音波のための透過領域として用いられるように配置されている形式のものにおいて、
超音波検査ヘッド(9,10)を備えたロール(3)は、これらのロール(3)間のロールギャップ幅(2)が調節されるように、調節可能であり、前記ロール(3)は、直線的な回転軸線方向の断面形状を有していて、ロールギャップ幅(2)の数倍の直径を有しており、それによって、ロール面と圧延品との間に、圧延角度により規定されるできるだけ大きい接触領域が得られるようになっており、圧延スタンド内における検査が圧延プロセス中に比較的早期に行われることにより、検査しようとする圧延材料の変形が、鋳造構造を解像するためにかつ圧延材料内の多孔性を密にするためには十分であるが、圧延材料内の含有物の伸張はまだ僅かであることを特徴とする、相前後して配置された複数の圧延スタンドを有する圧延ライン。 - 前記ロール(3)が片持式のロールであって、該片持式のロールにおいて、ロール外周面が少なくとも一方側で、外方に向かって圧延ディスク(6)から突き出したリング状の付加部(7)を有している、請求項1記載の圧延ライン。
- 超音波検査ヘッド(9,10)が、リング状の付加部(7)の、ロール軸線(4)に向いた側に配置されている、請求項1又は2記載の圧延ライン。
- 超音波が、ロールギャップ(2)内で圧延材料表面上に垂直に向けられている、請求項3記載の圧延ライン。
- 超音波が、ロールギャップ(2)内で圧延材料表面上に斜めに向けられている、請求項4記載の圧延ライン。
- マトリックス状に配置され、かつ互いに接続された複数の超音波検査ヘッド(9)が設けられている、請求項1から5までのいずれか1項記載の圧延ライン。
- 超音波検査ヘッドとして超音波放射器群が設けられている、請求項1から5までのいずれか1項記載の圧延ライン。
- 検査しようとする圧延材料(8)が、ロール部品によって一定の透過測定位置で保持されている、請求項1から7までのいずれか1項記載の圧延ライン。
- 検査しようとする圧延材料(8)が、前置接続及び/又は後置接続された圧延スタンドによって一定の透過測定位置で保持される、請求項1から7までのいずれか1項記載の圧延ライン。
