Description
Zerkleinern von Roheisenmasseln Die Zerkleinerung von Roheisenmasseln geschieht heute noch fast durchweg von Hand durch die sogenannten »Masselschläger«. Diese Arbeit ist verhältnismäßig umständlich, zeitraubend und mit großen körperlichen Anstrengungen verbunden.Crushing pig iron ingots The crushing of pig iron ingots is still done today almost entirely by hand using the so-called "pig mallet". This work is relatively cumbersome, time-consuming and involves great physical effort Efforts connected.
Man hat daher auch schon vorgeschlagen, die Zerkleinerung der Roheisenmasseln mittels elektrisch oder mit Preßluft betriebener Fallhämmer vorzunehmen, welche an die Verladekräne angehängt sind. Abgesehen davon, daß derartige Einrichtungen verhältnismäßig kostspielig sind, bedingen die durch die starken Schläge dieser Fallhämmer hervorgerufenen Erschütterungen übernormal kräftige Krankonstruktionen, welche in den meisten Fällen nicht vorhanden sind, so daß gegebenenfalls teure Verstärkungen der Krankonstruktionen erforderlich sind. Im übrigen können die Kräne für die Zeit der Zerkleinerung der Masseln nicht zum Verladen benutzt werden, so daß sich auch hieraus Störungen des Betriebes ergeben.It has therefore already been proposed that the pig iron ingot be comminuted using drop hammers operated electrically or with compressed air, which are attached to the loading cranes. Apart from the fact that such facilities are relatively expensive, due to the strong blows of these Shocks caused by drop hammers, exceptionally strong crane constructions, which in most cases are not available, so that expensive reinforcements may be necessary the crane structures are required. Incidentally, the cranes can be used for the time being the crushing of the pigs are not used for loading, so that too this results in operational disruptions.
Erfindungsgemäß wird nunmehr vorgeschlagen, die Zerkleinerung von Roheisenmasseln mittels an sich z. B. für Bauzwecke bekannter, jeweils von einem Mann gehandhabter Explosionsrammen vorzunehmen, und zwar vorzugsweise unmittelbar in dem z. B. aus Sand bestehenden Masselgießbett.According to the invention it is now proposed that the comminution of Pig iron ingots using per se z. B. known for construction purposes, each from one Man-made explosion hammers, preferably immediately in the z. B. consisting of sand ingot casting bed.
Die Verwendung derartiger Explosionsrammen hat die Vorteile, daß jegliche körperliche Anstrengung seitens der Leute fortfällt, daß die Anzahl der Arbeitskräfte verringert werden kann, daß die Arbeit mit Explosionsrammen die Verladung des Roheisens mittels Kran in keiner Weise behindert, daß das Bedienungspersonal nicht durch Schlauchleitungen oder andere Energiezuleitungen in seiner Bewegungsfreiheit gestört wird und daß insbesondere keine Veränderungen bzw. Verstärkungen der Krankonstruktionen erforderlich sind.The use of such explosive hammers has the advantages that any physical exertion on the part of the people that decreases the number of manpower it can be reduced that the work with explosion hammers the loading of the pig iron by means of a crane in no way hindered the operating personnel from being able to pass through hose lines or other energy supply lines are disturbed in its freedom of movement and that in particular, no changes or reinforcements to the crane structures are required are.
