Abstract

Blast-furnace slag spout or furnace spout is preformed from metal parts and water-cooled using an outer channel formed by either placing a pipe round the spout or using a second external wall, i.e. so the water flows through the resulting annular channel, thereby causing a covering layer of slag to form which functions as the actual slag spout or runner. The metal spout is pref. made of several overlapping metal parts and cooling may also be achieved using air. A tunnel for exhaust gas may also be located over the spout to reduce heat losses. Eliminates the time and cost involved in making a new spout or runner from sand after each tapping operation. Working conditions are improved.

Description

Die neuartige Hochofenschlackenrinne, die aus Metall besteht.The new blast furnace slag channel, which is made of metal.

Zweck des Verfahrens ist es, eine neuartige Hochofen- bzw.The purpose of the process is to create a new type of blast furnace or

Ofenrinne zu entwickeln. Diese soll die schwere Arbeit vor und nach jedem Abstich beseitigen, die Gesundheit der Menschen weniger belasten, die Unkosten durch Sandverbrauch zur Wiederherstellung der Schlackenrinne ersparen und die Arbeitszeit verkürzen.Develop furnace chute. This is supposed to do the heavy lifting before and after Eliminate every racking, reduce the burden on people's health, reduce costs save working time by using sand to restore the slag channel shorten.

Der heutige Stand der HochofenschLackenrinne Die heutige Hochofenschlackenrinne besteht aus Sandmasse, die'nach jedem Abstich abgebaut und mit neuem Sand wieder bedeckt werden muß. Diese Methode wiederholt sich alle .3 -4 Stunden je nach Größe des Hochofens.The current state of the blast furnace slag channel Today's blast furnace slag channel consists of sand mass, which is broken down after each tapping and with new sand again must be covered. This method repeats itself every 3-4 hours depending on the size of the blast furnace.

Der Erfindung liegt. die Aufgabe zugrunde, die Arbeit am Hochofen zu erleichtern, die Gesundheit der Menschen nicht zu belasten, die Verwendung von Sandmasse zu ersparen und die Arbeitszeit zu verkürzen. Diese Aufgabe wird technisch erfindungsmäßig dadurch gelöst, daß die Hochofenschlackenrinne nicht mehr durch Sandmasse abgedeckt wird, sondern durch zweiwandige 0 Metall-innen 1 (z.B. Kupfer) ersetzt wird, die dann mit Wasser abgekühlt 3 und ersetzt werden.The invention lies. the task underlying the work on the blast furnace to facilitate, not to burden people's health, the use of To save sand mass and to shorten the working time. This task becomes technical According to the invention solved in that the blast furnace slag channel no longer through Sand mass is covered, but by double-walled 0 metal inside 1 (e.g. copper) which is then cooled 3 with water and replaced.

Diese Metallrinnen bestehen aus mehreren Teilen, die durch Uberlappung 0 aufeinandergelegt werden können. Bei'Ausströmen der Schlacke in die Metallrinne bildet sich sofort eine Abdeckschicht, die aus Schlacke besteht, auf der Innenseite der Metallrinne und die sich als natürliche Schlackenrinne fUr die Hochofenschlacke benutzen läßt. Die Dicke dieser Abdeckschicht kann man beliebig unter Kontrolle halten. Nach Beendigung jeden Abstichvorganges und nach Abkühlung der Abdeckschicht kann die Wasserpumpe außer Betrieb gesetzt werden Je nach Stärke dieser Schicht kann Ir.ar die Metallrinne stückweise aufheben und die angesetzte Schlacke ausklopfen.These metal gutters consist of several parts that overlap 0 can be placed on top of each other. When the slag flows out into the metal channel A covering layer consisting of slag immediately forms on the inside the metal channel and which turns out to be a natural slag channel for the blast furnace slag lets use. The thickness of this cover layer can be controlled at will keep. After the end of each tapping process and after the cover layer has cooled down the water pump can be put out of operation depending on the thickness of this layer Ir.ar can pick up the metal channel piece by piece and knock out the slag.
