Abstract

Beim Richtvorgang treten bekanntlich an den Richtrollen der Richtmaschine unter anderem Vertikalkräfte auf, deren Größe von den Eigenschaften des Richtgutes, den Abmessungen der Richtmaschine und den gewählten Anstellungen der Richtrollen abhängen. Diese Kräfte bewirken eine elastische Verformung der Richtmaschine, insbesondere der Rollen, der Lager und des Rahmens, die das Richtergebnis des Richtgutes nachteilig beeinflussen. Um dies zu vermeiden, gilt es daher durch geeignete Maßnahmen, die Abhängigkeit des Richtergebnisses bei Rollenrichtmaschinen von Schwankungen und Streuungen der Eigenschaften des Richtgutes freizuhalten. Dies wird gemäß der Erfindung dadurch erreicht, daß jede senkrecht auf die Drehachsen der Richtrollen und/oder der Rollenlager und/oder auf den Rahmen der Richtmaschine wirkende Richtkraft für sich gemessen wird, und daß in Abhängigkeit der Meßwerte die Richtrollen im Bereich der auftretenden variierenden Druckkräfte automatisch nachgestellt werden.
