KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Ansätze in Hochöfen hat man bisher in der Weise zu entfernen versucht, daß man ein Loch in den Ofen brach und Pulver oder Dynamit unter den Ansätzen zur Explosion brachte. Da die Ansätze sich in der Regel in der Feuerzone des Ofens bilden, so ist die bisherige Art der Anwendung der Sprengstoffe für die Arbeiter mit einer gewissen Gefahr verknüpft. Diese soll durch die vorliegende ίο Vorrichtung beseitigt, außerdem aber neben der Explosionswirkung noch die zertrümmernde Kraft eines Geschosses benutzt werden.Approaches in blast furnaces have been tried to remove in such a way that one Hole in the furnace broke and exploded powder or dynamite under the lugs. As the approaches are usually Form in the fire zone of the furnace is the previous way of using explosives associated with a certain danger for the workers. This should be supported by the present ίο Device eliminated, but also next to The effect of the explosion can still use the shattering force of a projectile.
Ein Rohr α, am passendsten von 6o bis 65 mm lichter Weite, wird mit einer Spitze b aus Stahl oder Gußeisen, deren unterer Teil in das Rohr hineinpaßt, versehen.A tube α, most suitably with a clearance of 60 to 65 mm, is provided with a point b made of steel or cast iron, the lower part of which fits into the tube.
Rohr und Spitze werden durchbohrt und durch einen Stift c miteinander verbunden.The tube and tip are pierced and connected to one another by a pin c.
Diese Anordnung hat vor zugeschweißten Röhren den Vorzug:This arrangement has the advantage over welded tubes:
i. Es ist geringere Kraft erforderlich, um das Rohr zu zertrümmern und das Sprengmaterial zur Wirkung zu bringen.i. Less force is required to break the pipe and the explosives to bring to effect.
2. Die Spitze wird fortgeschleudert und wirkt wie ein Geschoß, was bei starken An-Sätzen im Hochofen von Wichtigkeit ist.2. The tip is thrown away and acts like a bullet, which is the case with strong approaches is important in the blast furnace.
Will man die Sprengwirkung nach einer bestimmten Stelle haben, so macht man in das Rohr α einen Schlitz d. If you want to have the explosive effect after a certain point, you make a slot d in the tube α.
Es ist einleuchtend, daß die Sprengwirkung sich dort, wo kein oder geringerer Widerstand ist, stärker äußert.It is evident that the explosive effect occurs where there is little or no resistance is, expresses more strongly.
