Description
AUSGEGEBEN AM 25. JULI 1919ISSUED ON JULY 25, 1919
Die Erfindung betrifft ein Schweißpulver, welches sich auch zum Schweißen, von Schnelldrehstählen eignet, deren Schweißen einerseits infolge ihrer hohen Schweißtemperatur und anderseits infolge ihres Gehaltes an bei der hohen Schweißtemperatur leicht oxydierbaren Metallen, wie insbesondere Chrom, Wolfram, Molybdän usw. Schwierigkeiten bietet, da die an den Oberflächen entstandene festhaftendeThe invention relates to a welding powder, which is also suitable for welding high-speed steels, their welding on the one hand due to their high welding temperature and, on the other hand, due to their content of at the high welding temperature easily oxidizable metals, such as chromium, tungsten, Molybdenum, etc. offers difficulties, since the firmly adhering formed on the surfaces
ίο und schwer schmelzbare Öxydschicht obiger Metalle auf eine Verschweißung hemmend wirkt. ·ίο and hard-to-melt oxide layer above Metal has an inhibiting effect on welding. ·
Das Schweißpulver gemäß der Erfindung besteht dem Wesen nach aus einer fein zerkleinerten Mischung von'siliziumhaltigem Eisen (Roheisen oder Ferrosilizium), Alkali- (Ammon- oder Erdalkali-) Karbonat und Alkali- (Ammon- oder Erdalkali;) Phosphat oder Silizat (auchj Kieselsäure), gegebenenfalls mit Zusatz von kohlenstoffhaltigen Stoffen, z, B. Blutlaugensalz und eines Flußmittels, wie Alkali-, Ammon- oder Erdalkalihalojdsalz.The welding powder according to the invention essentially consists of a finely crushed one Mixture of iron containing silicon (pig iron or ferrosilicon), alkali (ammonium or alkaline earth) carbonate and alkali (ammonium or alkaline earth;) phosphate or silicate (including silica), optionally with the addition of carbonaceous substances, e.g. blood liquor salt and a flux such as alkali, ammonium or alkaline earth halide salt.
Diese eigenartige Mischung des stark reduzierenden und desoxy dierendeh Siliziumeisens, des Metalloxyde gut aufschließenden Karbonats und der Metalloxyde ,gut auflösenden Phosphat- oder Silizat-Schlackenbildner ermöglicht es, daß die zum Schweißen der Schnelldrehstähle erforderliche hohe Hitze angewendet und eine die Verschweißung hemmende Oxydschicht leicht entfernt werden kann.This peculiar mixture of the strongly reducing and deoxidizing silicon iron, of the metal oxides, which dissolve well, and of the metal oxides, which dissolve well, of phosphate or silicate slag former enables the high speed steels to be welded Required high heat is applied and an oxide layer that inhibits welding can be easily removed.
Die Bestandteile werden in kalziniertem und fein zerkleinertem Zustande miteinander innig gemischt.The constituents become intimate with one another in the calcined and finely comminuted state mixed.
Phosphorsaures Natron oderSoda or phosphoric acid
Kieselsäure 250 g,Silica 250 g,
Soda 200 g,Soda 200 g,
Kalziumfluorid 50 g,Calcium fluoride 50 g,
Roheisenpulver, etwa mit 2
bis 6 Prozent Siliziumgehalt 500 g. Pig iron powder, roughly with 2
up to 6 percent silicon content 500 g.
Selbstverständlich können die Gewichtsverhältnisse je nach dem Verwendungszweck und der erforderlichen Dünnflüssigkeit der Schlacke innerhalb gewisser Grenzen geändert werden, ohne die Metalloberflächen reinigende und die Oxyde auflösende Wirkung wesentlich zu beeinträchtigen. - -Of course, the weight ratios can vary depending on the intended use and the required thin liquidity of the slag can be changed within certain limits, without significantly impairing the effect of cleaning the metal surfaces and dissolving the oxides. - -
Dementsprechend können mit einem Schweißmittel gemäß vorliegender Erfindung nicht nur die schwer schweißbaren Schnelldrehstähle, sondern auch alle sogenannten legierten Stähle, sowie auch die übrigen leichter und bei niedrigerer Temperatur schweißbaren Stahl- und Eisensorten, sowie Gußeisen in ähnlicher Weise, wie Schnelldrehstähle geschweißt werden, indem man z. B. das Schweißmittel zwischen den zu vereinigenden Flächen der auf Rotglut erhitzten Stücke streut und diese bei der entsprechenden Schweißhitze durch Druck vereinigt. Accordingly, with a welding means according to the present invention not only the hard-to-weld high-speed steels, but also all so-called alloyed steels, as well as the other lighter and at lower temperature weldable steel and Types of iron, as well as cast iron, are welded in a similar way to high-speed steels by one z. B. the welding agent between the surfaces to be united on red heat Scattered heated pieces and these united by pressure at the corresponding welding heat.
