Description
Vynález sa týká aglomerovaného taviva na automatické zváraníe pod tavivom, konštrukčných nelegovaných a nízkolegovaných ocelí.The invention relates to agglomerated flux for automatic submerged arc welding, structural unalloyed and low alloy steels.
Pre zváraníe nelegovaných a. niektorých nízkolegovaných ocelí, ktoré · zabezpečujú požadované vlastnosti do teploty —20 °C je potřebné tavivo majúce velmi dobré operativně vlastnosti, to znamená, že zabezpečuje stabilně horenie oblúka, samovolná odstránitelnosť trosky, súmerné formovanie húsenky, a to pri zváraní v úkose alebo kútového spoja. Tieto vlastnosti zabezpečujú kyslé tavívá. Podlá sposobu výroby móžu byť tavívá tavené alebo aglomerováné. Tavené tavívá potrebujú pre výrobu niekol'konásobne viac elektrickej energie, pričom znečisťujú pracovně prostredie v porovnaní s netavenými tavivami. Netavené tavívá v porovnaní s tavenými metalurgicky priaznivejšie vplývajú na húževnatosť zvarového kovu.For welding of unalloyed and. Some low-alloy steels which provide the required properties up to -20 ° C require a flux having very good operational properties, ie it ensures stable arc burning, spontaneous slag removal, symmetrical bead formation, when welding or corner welding . These properties provide acid fluxes. According to the manufacturing process, they can be fused or agglomerated. Fused fluxes require several times more electrical energy to produce, while polluting the working environment compared to non-fused fluxes. Non-melted melts have a more favorable effect on the toughness of the weld metal compared to melted metallurgically.
V praxi je známe tavené tavivo kyslého typu, ktoré obsahuje 35—45 % hmot. oxidu křemičitého, 33 až 42 % hmot. oxidu manganatého, 5 až 10 % hmot. oxidu hlinitého, 4 až 10 % hmot. oxidu vápenatého, 3 až 8 % fluoridu vápenatého, ďalšie komponenty sú oxid horečnatý, oxid titaničitý, oxid sodný a oxid draselný. Tavivo má stabilně horenie oblúka, ale v úkose nemá dobrá odstránitelnosť trosky, vyskytuje sa zapekanie na povrchu húsenky, formovacie vlastnosti húsenky sú velmi dobré.In practice, a fused acid type flux is known which contains 35-45 wt. % silica, 33 to 42 wt. % manganese dioxide, 5 to 10 wt. % alumina, 4 to 10 wt. calcium components, 3 to 8% calcium fluoride, other components are magnesium oxide, titanium dioxide, sodium oxide and potassium oxide. The flux has a stable arc burning, but it does not have good slag removability at the slope, there is a fusing on the surface of the caterpillar, the forming properties of the caterpillar are very good.
Aglomerovaným tavivom podlá vynálezu sa do značnej miery odstránia uvedené nedostatky. Predmetom vynálezu je aglomerované tavivo nasledovného zloženia, 20 až 38 % hmot. oxidu křemičitého, 5 až 15 % hmot. oxidu manganatého, 29 až 40 % hmot. oxidu hlinitého, 2 až 10 % hmot. oxidu horečnatého, 0,1 až 5 % hmot. oxidu vápenatého, 2 až 9 % hmot. oxidu sodného a draselného spolu, 4 až 15 % hmot. fluoridu vápenatého, zvyšok tvoria nečistoty ako οχιά železnato-železitý, fosfor a síra.The agglomerated flux according to the invention largely removes the above drawbacks. The subject of the invention is an agglomerated flux of the following composition, 20 to 38 wt. % silica, 5 to 15 wt. % manganese dioxide, 29 to 40 wt. % alumina, 2 to 10 wt. % magnesium oxide, 0.1 to 5 wt. % calcium oxide, 2 to 9 wt. % sodium and potassium oxide together, 4 to 15 wt. calcium fluoride, the remainder being impurities such as ferrous iron, phosphorus and sulfur.
Pri zváraní tavivom podlá vynálezu sa dosahujú dobré operativně a metalurgické vlastnosti. Horenie oblúka je stabilně, čo sa dosiahlo optiinálnym zastúpenim oxidu sodného a oxidu draselného. Odstránitelnosť trosky je samovolná aj pri zváraní v úkose. Húsenka je súmerne formovaná s hladkým povrchom. Aglomerované tavivo má priaznivý vplyv na mechanické vlastnosti zvarového kovu. Vplýva na dosiahnutie prlaznivej štruktúry a čistoty zvarového kovu.The fusion welding according to the invention achieves good operative and metallurgical properties. The arc burning is stable, which was achieved by the optimal representation of sodium oxide and potassium oxide. Removability of the slag is spontaneous even when welding in a slope. The caterpillar is symmetrically formed with a smooth surface. The agglomerated flux has a beneficial effect on the mechanical properties of the weld metal. It influences the creeping structure and purity of the weld metal.
Podlá vynálezu bolo vyrobené tavivo, ktoré pozostávalo v jednom případe z 29,4 % hmot. oxidu křemičitého, 8,3 % hmot. oxidu manganatého, 34,7 % hmot. oxidu hlinitého, 8,9 % hmot. oxidu horečnatého, 3,2 pere. hmot. oxidu vápenatého, 4,3 % hmot. oxidu sodného a draselného, 8,2 % hmot. fluoridu vápenatého, 2,9 % hmot. oxidu železnato-železitého, 0,025 °/o hmot: fosforu a 0,02 % hmot. síry. V kombinácii s nelegovaným mangánovým drotom, 1,4 % hmot. raangánu, sa dosiahli následovně hodnoty vrubovej hůževnatosti KCU 3 zvarového kovu: 160 Jcm-2 pri teplote —20 °C a 120 Jom-2 pri teplote —40 °C.According to the invention, a flux was produced, which in one case consisted of 29.4 wt. % silica, 8.3 wt. % manganese dioxide, 34.7 wt. % alumina, 8.9 wt. of magnesium oxide, 3.2 pere. wt. % calcium oxide, 4.3 wt. % sodium and potassium oxide, 8.2 wt. % of calcium fluoride, 2.9 wt. ferric iron oxide, 0.025 wt.% phosphorus and 0.02 wt. sulfur. In combination with unalloyed manganese wire, 1.4 wt. The values of notch toughness KCU 3 of the weld metal were achieved as follows: 160 Jcm -2 at -20 ° C and 120 Jom -2 at -40 ° C.
V ďalšom případe bolo podlá vynálezu vyrobené tavivo, skladajúce sa z 25,3 °/o hmot. oxidu křemičitého, 10,1 % hmot. oxidu manganatého, 38,5 % hmot. oxidu hlinitého, 7,7 % hmot. oxidu horečnatého, 2,8 °/o hmot. oxidu vápenatého, 4,2 % hmot. oxidu sodného a draselného, 8,1 % hmot. fluoridu vápenatého, 3,2 u/o hmot. oxidu železnato-železitého, 0,03 % hmot. fosforu, 0,02 pere. hmot. síry.In another case, a flux consisting of 25.3 wt. % silica, 10.1 wt. % manganese dioxide, 38.5 wt. % alumina, 7.7 wt. of magnesium oxide, 2.8 wt. % calcium oxide, 4.2 wt. % sodium and potassium oxide, 8.1 wt. calcium fluoride, 3.2 u / o wt. % ferric iron oxide, 0.03 wt. phosphorus, 0.02 pere. wt. sulfur.
V kombinácii s nelegovaným mangánovým drůtom, 0,6 % hmot. mangánu, dosiahli sa následovně hodnoty vrubovej hůževnatosti KCU 3 zvarového kovu: 140 Jcm-2 pri teplote 20 °C a 80 Jcm-2 pri teplote —40 °C.In combination with unalloyed manganese wire, 0.6 wt. Manganese, the following values of notch toughness KCU 3 of the weld metal were achieved: 140 Jcm -2 at 20 ° C and 80 Jcm -2 at -40 ° C.
Aglomerované tavivo podlá vynálezu představuje pokrok v porovnaní s doteraz známými tavenými tavivami, čo sa týká operatívnych vlastností a metalurgického vplyvu taviva na zvarový kov.The agglomerated flux according to the invention represents an improvement over the previously known fused fluxes in terms of the operational properties and metallurgical effect of the flux on the weld metal.
