Description
Gegenstand des Hauptpatentes P 19 06 461.6-24 ist ein schnellhärtendes Bindemittel zur Herstellung von Rinnenauskleidungs- bzw. Stichlochstopfmassen für den Hochofenabstich aus 50 bis 95% eines bituminösen Destillationsrückstandes, vorzugsweise eines in wesentlichen Mengen phenolische Bestandteile enthaltenden Destillationsrückstandes, und 50 bis 5% eines Gemisches aus Novolak und Hexamethylentetramin.The subject of the main patent P 19 06 461.6-24 is a fast-curing binder for the production of Channel lining or tap hole plugging compounds for blast furnace tapping made from 50 to 95% bituminous Distillation residue, preferably one containing substantial amounts of phenolic constituents Distillation residue, and 50 to 5% of a mixture of novolak and hexamethylenetetramine.
Es wurde überraschenderweise gefunden, daß beim Vorgehen nach der Hauptpatentanmeldung 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 application when using a distillation residue containing substantial amounts of phenolic constituents Novolak content can advantageously be omitted.
Gegenstand der Erfindung ist also ein schnellhärtendes Bindemittel zur Herstellung von Rinnenauskleidungs- bzw. Stichlochstopfmassen für den Hochofenabstich gemäß Patentanmeldung P 19 60461.6-24 das dadurch gekennzeichnet ist, daß man in Abwandlung des Vorgehens nach der Hauptpatentanmeldung bei Verwendung eines in wesentlichen Mengen phenolische Bestandteile enthaltenden Destillationsrückstandes ein Gemisch nur aus diesem Destillationsrückstand undThe subject of the invention is therefore a fast-hardening binder for the production of gutter lining or tap hole tamping compounds for blast furnace tapping according to patent application P 19 60461.6-24 das is characterized in that in a modification of the procedure according to the main patent application Use of a distillation residue containing substantial amounts of phenolic constituents Mixture only from this distillation residue and
Hexamethylentetramin im Verhältnis von 85 bis 97% DestilationsrOckstand zu 15 bis 3% Hexamethylentetramin — unter Weglassen des Novolakantefls — verwendetHexamethylenetetramine in a ratio of 85 to 97% distillation residue to 15 to 3% hexamethylenetetramine - with omission of the novolak cantefls - used
Als im wesentlichen Mengen phenolische Bestandteile enthaltender Destillationsrückstand werden z.B. Phenoipech oder Braunkohlenteerpech, vorzugsweise ein Destillationsrückstand des bei der Phenolsynthese nach dem Cumolverfahren anfallenden Rückstands verwendetDistillation residue containing substantial amounts of phenolic constituents is e.g. Phenol pitch or lignite tar pitch, preferably a distillation residue from the phenol synthesis residues obtained after the cumene process are used
Zur Herstellung des Bindemittels werden die beiden Komponenten in pulvriger Form bei Raumtemperatur vermischtTo produce the binder, the two components are in powder form at room temperature mixed
Für die Herstellung einer Stichlochstopfmasse unter Verwendung 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 und 4000C, z. B. eines Steinkohlenteeröls oder eines Öles aus dem Rückstand der Benzinpyrolyse, mit 85 bis 55 Gew.-Teilen eines Gesteinsmehles.For the preparation of a taphole mass using the fast-curing binder to 5 5 to 15 parts by weight of fine coal, and 5 to 15 parts by weight blended to 15 parts by weight of binder, of a highly aromatic oil having a boiling range between 250 and 400 0 C, e.g. . B. a coal tar oil or an oil from the residue of gasoline 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.
5 Gew.-Teile Hexamethlentetramin, technisch, werden in pulvrisiertem Zustand mit 95 Gew.-Teilen eines Destillationsrückstandes des bei der Phenolsynthese nach dem Cumol-Verfahren anfallenden Rückstandes gemischt.5 parts by weight of hexamethlentetramine, technical, are powdered with 95 parts by weight of a Distillation residue of the residue obtained in the phenol synthesis by the cumene process mixed.
Zur Herstellung der Rinnenauskleidungsmasse werden 25 Gew.-Teile dieses Bindemittelgemisches mit 75 Gew.-Teilen Klebsand gemischt Das Gemisch wird in eine vorgefertigte Form aus Eisen gestampft und in einen auf 400°C vorgeheizten Ofen gebracht Nach 10 min ist das Gemisch durchgehärtet und formstabil.To produce the gutter lining compound, 25 parts by weight of this binder mixture are added 75 parts by weight of adhesive sand mixed. The mixture is tamped into a prefabricated form made of iron and in placed in an oven preheated to 400 ° C. After 10 minutes, the mixture has hardened through and is dimensionally stable.
Beispiel 2
Herstellung einer StichlochstopfmasseExample 2
Manufacture of a tap hole tamping compound
12,5 Gew.-Teile des Bindemittels aus Beispiel 1 werden mit 12,5 Gew.-Teilen Feinkohle, 10 Gew.-Teilen Teeröl vom Siedebereich zwischen 250 bis 400° C und 65 Gew.-Teilen Kaolinsand gemischt.12.5 parts by weight of the binder from Example 1 are mixed with 12.5 parts by weight of fine coal, 10 parts by weight of tar oil with a boiling range between 250 to 400 ° C. and 65 parts by weight of kaolin sand.
Das Gemisch läßt sich mit einem preßluftgetriebenen Kolben durch eine sich von rd. 25 cm auf 5 cm Durchmesser verjüngende Düse drücken.The mixture can be drawn through a piston driven by compressed air from about 25 cm to 5 cm Press the nozzle with the tapering diameter.
In eine Form gestampft, wird das Gemisch in einen auf 400° C bis 4500C vorgeheizten Ofen gebracht Es härtet nach 10 min zu einer formfesten Masse durch, ohne sich zu entzünden.In one form mashed, the mixture is brought into a pre-heated to 400 ° C to 450 0 C oven It cures after 10 min to form solid mass through without being ignited.
