Abstract

Rapidly setting composn. suitable for trough cladding or tap-hole plugs of blast furnaces with a long storage life made by mixing as binder for a stone meal 5% of hexamethylenetetramine with 95% of a distillation residue (obtained from the phenol synthesis by the cumene process) rich in phenolics. The binder is mixed with the other ingredients and the mixture cured after forming at about 400 degrees C. Novolaks are not required.

Gegenstand des Hauptpatentes ... (Patentanmeldung ist ein schnelihärtendes Bindemittel zur Iierstollung von Rinnenauskleidungs- bzw. Stichlochstopfmassen für den flochofenabstich aus 50 bis 95 % eines bituminösen Destillationsrückstands, vorzugsweise eines in wesentlichen Mengen phenolische Bestandteile enthaltenden Destillationsrüc]cstands, und 50 bis 5 % eines Gemisches aus Novolak und Hexamethylentetramin.Subject of the main patent ... (patent application is a fast-setting binding agent for tunnels of gutter lining or tap hole tamping compounds for tapping flasks from 50 to 95% of a bituminous distillation residue, preferably a distillation residue containing substantial amounts of phenolic constituents, and 50 to 5% of a mixture of novolak and hexamethylene tetramine.

Es wurde überraschenderweise gefunden, daß beim Vorgehen nach dem Haupatent bei Verwendung eines in wesentlichen Mengen phenolische Bestandteile enthaltenden Destillationsrückstands der Novolakanteil vorteilhafterweise fortgelassen werden kann.It has surprisingly been found that when proceeding according to the Main patent when using a substance containing phenolic constituents in substantial amounts The novolak portion can advantageously be omitted from the distillation residue can.

Gegenstand der Erfindung ist also ein schnelihärtendes Dindemittel zur llerstellung von Rinnenauskleidungs- bzw. Stichlochstopfmassen für den Hochofenabstich gemäß Patentanm. das dadurch gekennzeichWet ist, daß Pa te ntaL1( r \rl E99 Yp,o man in Abwandlung des Vorgehens nach bei Verwendung eines in wesentlichen Mengen phenolische Bestandteile enthaltenden Destillationsrückstands ein Gemisch nur aus diesem Destillationsrückstand und Hexamethylentetramin im Verhältnis von bis 97 % Destillationsrückstand zu 15 bis 3 % Ilexamethylentetramin - unter Weglassen des Novolakanteils - - verwendet.The subject matter of the invention is therefore a fast-hardening binder for the production of gutter lining or tap hole plugging compounds for blast furnace tapping according to patent application. that thereby It is marked that Pa te ntaL1 (r \ rl E99 Yp, o a mixture of this distillation residue and hexamethylenetetramine in a ratio of up to 97% distillation residue to 15 to 3% ilexamethylenetetramine - omitting the novolak component - is used as a modification of the procedure when using a distillation residue containing substantial amounts of phenolic constituents.

Als in wesentlichen Mengen phenolische Bestandteile enthaltender Destillationsrückstand werden z.B. Phenolpech, Braunkohlenteerpech oder ähnliches, vorzugsweise ein Destillationsrückstand des bei der Phenolsynthese nach dem Cumolverfahren anfallenden Rückstands verwendet.As a distillation residue containing substantial amounts of phenolic constituents e.g. phenol pitch, lignite tar pitch or the like, preferably a distillation residue of the residue obtained in the phenol synthesis by the cumene process.

Zur 1lerstellung des Bindemittels werden die beiden Komponenten in pulvriger Form bei Raumtemperatur' vermischt.To produce the binding agent, the two components are used in powdery form at room temperature 'mixed.

Für die Herstellung einer Stichlochstopfnxasse unter Verwenduns des schnellhärtenden Bindemittels mischt man 5 bis 15 Gew.-Teile Bindemittel, 5 bis 15 Gew.-Teile Feinkohle und 5 bis 15 Gew.-Teile eines aromatenreichen Öles vom Siedebereich zwischen 250 bis 400°C, z.B. eines Steinkohlenteoröls oder eines Öles aus dem Rückstand der Benzinpyrolyse, mit 85 bis 55 Gew.-Teilen eines Gesteinsmehles.For the production of a tap hole plug using the fast-curing binder is mixed 5 to 15 parts by weight of binder, 5 to 15 parts by weight of fine coal and 5 to 15 parts by weight of an oil rich in aromatic compounds from the boiling range between 250 and 400 ° C, e.g. a coal tar oil or an oil from the residue petrol pyrolysis, with 85 to 55 parts by weight of a rock flour.

Die nachstehenden Beispiele sollen die Erfindung näher erläutern.The following examples are intended to explain the invention in more detail.

Beispiel 1 5 Gew.-Teile Hexamethylentetramin, technisch, werden in pulvrisiertem Zustand mit 95 Gew.-Teilen eines Dostillationsrückstandes des bei der Phenol synthese nach dem Cumol-Vcrfahren anfallenden Rückstandes gemischt.Example 1 5 parts by weight of hexamethylenetetramine, technical, are in powdered state with 95 parts by weight of a distillation residue of the the phenol synthesis mixed by the cumene process.

Zur lierstellung der Rinnenausicleidungsmasso werden 25 Gew.-Teile dieses Bindemittelgemisches mit 75 Gew.-Teilen Klebsand gemischt. Uas Gemisch wird in eine vorgefertigte Form aus Eisen gostampft und in einen auf 400°c vorgeheizten Ofen gebracht. Nach 10 min ist das Gemisch durchgehärtet und formstabil.25 parts by weight are used to create the Rinnenausicleidungsmasso this binder mixture mixed with 75 parts by weight of adhesive sand. Uas mixture is stamped in a prefabricated iron mold and preheated to 400 ° C Oven brought. After 10 minutes the mixture has hardened and is dimensionally stable.

Beispiel 2 Herstellung einer Stichlochstopfmasse 12,5 Gew.-Teile des Bindemittels aus Beispiel 1 werden mit 12V5 Gew.-Teilen Feinkohle, 10 Gew.-Toilen Teerol vom Siedebereich zwischen 250 bis 4000C und 65 Gew.-Teilen Kaolinsand gemischt.Example 2 Production of a tap hole tamping compound 12.5 parts by weight of the The binder from Example 1 is mixed with 12 V5 parts by weight of fine coal and 10 parts by weight of toilets Teerol from the boiling range between 250 to 4000C and 65 parts by weight Kaolin sand mixed.

I)as Gemisch läßt sich mit einem preßluftgetriebenen I(olben durch eine sich von rd. 25 cm auf 5 cm Durchmesser verjüngende Düse drücken.I) the mixture can be passed through with a compressed air-driven piston Press a nozzle that tapers from around 25 cm to 5 cm in diameter.

In eine Form gestampft, wird das Gemisch in einen auf 400°C bis 450°C vorgeheizten Ofen gebracht. Es härtet nach 10 min zu einer formfesten Masse durch, ohne sich zu entzünden.Tamped into a mold, the mixture is poured into a 400 ° C to 450 ° C preheated oven brought. It hardens to a dimensionally stable mass after 10 minutes, without igniting.
