Description
Vynález sa týká taviva pře naváranie vysokolegovanou pásovou elektrodou antikoróznych vrstiev na nelegované, nízkolegované a austenitické ocele.The present invention relates to a flux for the welding of a high-alloyed band electrode of anticorrosive layers to unalloyed, low-alloy and austenitic steels.
V procese navárania pásovou elektródou pod tavivom má tavivo rozhodujúci vplyv na formovanie húsenky, odstránitefnosť trosky a chemické zloženie návaru. Dobré formovanie húsenky a samovolná odstránitel'nosť trosky sú nevyhnutné pre dosiahnutie bezchybného návaru. Tendencia zapekania trosky sa zvyšuje hlavně pri naváraní pásovými elektrodami obsahujúcimi niób.In the strip electrode welding process below the flux, the flux has a decisive influence on the formation of the bead, the slag removability and the chemical composition of the deposit. Good bead formation and spontaneous slag removability are essential to achieve flawless buildup. The tendency of slag baking increases mainly when welding with niobium-containing band electrodes.
Nepriaznivý metalurgický účinok taviva sa prejaví na chemickom zložení návaru, a to v nalegovaní kremíka a prepale chrómu a niobu. Zvýšenie obsahu kremíka sposobí vznik horácích trhlin v návare. Zníženie obsahu chrómu a niobu zhoršuje odolnost proti medzikryštálovej korózii.The unfavorable metallurgical effect of the flux is reflected in the chemical composition of the deposit, namely in the deposition of silicon and the burn of chromium and niobium. Increasing the silicon content will result in bursting cracks in the buildup. Reducing chromium and niobium deteriorates the resistance to intergranular corrosion.
Je známe tavivo s nasledovným zložením: 6 až 15 % hmot. oxidu křemičitého, 1 až 7 pere. hmot. oxidu manganatého, 36,7 až 47 pere. hmot. oxidu hlinitého, 1 až 4 % hmot. oxidu horečnatého, 10 až 17 % hmot. oxidu vápenatého, 1 až 3 % hmot. oxidu sodného a draselného spolu, 16 až 26 % hmot. fluoridu vápenatého, 1 až 8 % hmot. fluoridu barnatého. Uvedené tavivo nemá dobré operatívne vlastnosti. Húsenka je hrbolatá a v střede přepadnutá. Vyskytuje sa zapekanie trosky na povrchu húsenky.A flux having the following composition is known: 6 to 15 wt. silica, 1 to 7 washes. wt. manganese dioxide, 36.7 to 47 washes. wt. % alumina, 1 to 4 wt. % magnesium oxide, 10 to 17 wt. % calcium oxide, 1 to 3 wt. % of sodium and potassium oxide together, 16 to 26 wt. % calcium fluoride, 1 to 8 wt. barium fluoride. Said flux does not have good operational properties. The caterpillar is bumpy and stuck in the middle. There is a slag baking on the surface of the caterpillar.
Je známe tavené tavivo o nasledovnom chemickom zložení: 28 až 38 % hmot. oxidu křemičitého, 15 až 29 % hmot. oxidu hlinitého, 5 až 13 % hmot. oxidu vápenatého, 10 až 18 % hmot. fluoridu vápenatého, 17 až 30 % oxidu horečnatého, 0,2 až 2,5 % hmot. oxidu sodného a draselného spolu, 0,8 až 8 % hmot. oxidu barnatého, 1 až 6 °/o hmot. oxidu manganatého. Toto tavivo má dobré formovanie húsenky vďaka vysokému obsahu kysličníka křemičitého. Vysoký obsah kysličníka křemičitého sposobuje sílnú redukciu kremíka z taviva do návaru, čo sposobuje náchylnost na praskanie za tepla.A fused flux having the following chemical composition is known: 28 to 38 wt. % silica, 15 to 29 wt. % alumina, 5 to 13 wt. % calcium oxide, 10 to 18 wt. % calcium fluoride, 17 to 30% magnesium oxide, 0.2 to 2.5% wt. % sodium and potassium oxide together, 0.8 to 8 wt. % barium oxide, 1-6% by weight. manganese dioxide. This flux has good bead formation due to the high silica content. The high silica content causes a strong reduction of silicon from the flux to the weld deposit, which makes it vulnerable to hot cracking.
Uvedené nedostatky do značnej miery odstraňuje tavivo pre naváranie s vysokolegovanou pásovou elektródou antikoróznych vrstiev na nelegované, nízkolegované a austenitické ocele, ktoré obsahuje oxid sodný a draselný, oxid horečnatý, podstata ktorého spočívá v tom, že ďalej pozostáva z oxidu křemičitého od 4 do 12 % hmot., oxidu hlinitého od 24 do 33 °/o hmot., oxidu manganatého od 7,1 do 10 % hmot., oxidu vápenatého od 0,1 do 6 % hmot., oxidu barnatého od 8,1 do 12 % hmot. a fluoridu vápenatého od 35 do 45 % hmot.The aforementioned drawbacks are largely eliminated by the flux for welding with a high-alloy strip electrode of the corrosion-resistant layers on non-alloyed, low-alloy and austenitic steels containing sodium and potassium oxide, magnesium oxide, which further consists of silica from 4 to 12% % alumina from 24 to 33% by weight, manganese oxide from 7.1 to 10% by weight, calcium oxide from 0.1 to 6% by weight, barium oxide from 8.1 to 12% by weight; % and calcium fluoride from 35 to 45 wt.
Pri naváraní pásovou elektródou s tavivom pódia vynálezu je stabilně horenie -obláká. Húsenka je rovnoměrně formovaná s hladkým povrchom. Odstránitefnosť trosky je samovolná aj pri narábaní s pásovou elektródou obsahujúcou niób. Spotřeba taviva je nízká, asi 0,7 kg taviva na 1 kg navařeného kovu. Dobré formovanie a dobrá odstránitefnosť trosky sa dosiahla optimáln-ou kombináciou oxidov křemičitého, hlinitého a horečnatého.When welding with a fluxing electrode with a flux according to the invention, the flame is stably flame-retardant. The caterpillar is evenly formed with a smooth surface. The slag removability is also spontaneous when handling a niobium-containing band electrode. The flux consumption is low, about 0.7 kg of flux per kg of weld metal. Good molding and good slag removability were achieved by an optimal combination of silica, alumina and magnesium oxides.
