Description
Feststellen des leeren Raumes zwischen Beschickungssäule und der Gicht bei Schachtöfen, insbesondere Hochöfen Bei Schachtöfen, insbesondere Hochöfen, ist es wichtig, die Höhe und Formung der Besoh.ickungssäule bzw. .den Abstand ihrer oberen Begrenaung von der Schachtöffnung brzw. von .der Gicht möglichst oft feststellen zu können. An Hand dieser Feststellung würde man in der Lage sein, Unregelmäßigkeiten in der gewünschten Formbildung der Beschickungsoberfläche möglichst frühzeitig auszugleichen, damit die obere Begrenzung der Beschickungssäule möglichst gleichmäßig auf .der vorbestimmten Höhe gehalten werden kann.Determine the empty space between the charging column and the gout in shaft furnaces, especially blast furnaces. In shaft furnaces, especially blast furnaces, is it is important to determine the height and shape of the filling column or the distance between it upper border of the shaft opening brzw. of gout as often as possible to be able to. Based on this finding, one would be able to identify irregularities to compensate for the desired shape of the loading surface as early as possible, so that the upper limit of the charging column as evenly as possible on the predetermined height can be maintained.
Man hat bisher versucht, den Zwischenraum zwischen der oberen Begrenzung der Beschickungssäule und der Schachtöffnung durch Einführen von Sonden zu messen. Dieses Vorgehen ist jedoch umständlich und nicht immer sicher, vor allem dann, wenn die Beschickungssäule an ihrer Oberfläche nicht waagerecht verläuft, sondern Mulden bildet oder tütenförmig absinkt, zumal nur an einigen wenigen Punkten, zumeist zwei oder drei, gemessen werden kann. Außerdem muß diese Vorrichtung bei jedem Beschickungsvorgang herausgefahren werden, um nicht durch das Beschickungsgut beschädigt zu werden.So far, attempts have been made to reduce the space between the upper limit to measure the charging column and the shaft opening by inserting probes. However, this procedure is cumbersome and not always safe, especially when the charging column does not run horizontally on its surface, but troughs forms or sinks in the shape of a bag, especially only at a few points, mostly two or three, can be measured. In addition, this device must be used for each loading process be moved out so as not to be damaged by the load.
Erfindungsgemäß wird der Abstand der Oberfläche der Beschickunassäule von der Schacht-I öffnung bei Schachtöfen, insbesondere Hochöfen, mittels Wellen bestimmt, -die von einer am Schachtverschluß angeordneten Vorrichtung ausgesendet und von der Oberfläche der Beschickungssäule zurückgeworfen werden; z. B. mittels an sich bekannter Echoloteinrichtungen, die Schalhvellen erzeugen und die Zeit bestimmen, .die zwischen Absendung und Wiedereintreffen nach Reflektion durch die Oberfläche der Beschickungssäule verstreicht. Die Vorrichtungen gestatten, gleichgültig, welche Wellenart verwendet wird, die fortlaufende Registrierung und Fernübertragung z. B. unter Benutzung von Braunschen Röhren od. dgl. Es ist auch möglich, die gesamte Oberfläche der Beschickungssäule gewissermaßen abzutasten, so daß Meßfehler, die infolge von starken Unebenheiten der Oberfläche der Beschickungssäule auftreten könnten, eliminiert werden.According to the invention, the distance between the surface of the charging column becomes from the shaft opening in shaft furnaces, in particular blast furnaces, by means of shafts determined, -the sent out by a device arranged on the shaft closure and bounced back from the surface of the feed column; z. B. by means of known echo sounder devices that generate sound waves and determine the time, . that between sending and re-arrival after reflection by the surface of the feed column passes. The devices allow, indifferently, which wave type is used, the continuous registration and remote transmission z. B. od using Braun tubes. Like. It is also possible to use the entire To scan the surface of the charging column, so to speak, so that measurement errors that occur as a result of severe unevenness in the surface of the charging column could be eliminated.
