Description

CS 269 043 Bl 1CS 269 043 B1 1

Vynález se týká zloženia náplně trubičkového ocelového drotu na automatic-ká naváranie v ochraně plynov, pod tavivom alebo elektrotrosková naváranie vrstievodolných najma voči abrazivnemu a erozivnemu opotrebeniu.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a filler composition for a tubular steel wire for automatic welding in gas protection, underflux or electrosurface welding, especially for abrasive and erosive wear.

Naváranie legovanými rurkovými drotmi nadobudlo v poslednom obdobi velkývýznam, 3e to daná Jednoduchšou výrobou legovaných rúrkových drotov pre automa-tická sposoby naváranie v porovnaní a legovanými plnými drotmi. Možno nimi získatáirokú paletu zloženia návarových kovov. Náplně známých ocelových trubičkových dr£tov určených na naváranie vrstievodolných najma proti abrazivnemu a erozivnemu opotrebeniu obsahujú v jednom pří-pade 40 až 50 % hmot, ferochrómu, 1 až 5 % hmot, ferovanádu, 8 až 12 % hmot, fero-titanu, 2 až 16 % hmot. feromolybdánu a zvyáok železo. V čalšom případe náplňobsahuje 3 až 5 % hmot, grafitu, 8 až 15 % hmot. ferowolfrámu, 2 až 4 % hmot. fero-bóru, 1 až 4 % hmot, ferotitanu a 1 až 4 % hmot. ferovanáda, Oaláia náplň podláCSSR AO č. 226 585 obsahuje 1,3 až 4 % hmot, feromolybdánu, 1 ež 4 % feromangánu, 1 až 4 % hmot, fluorokremičitanu sodného, 14,1 až 19,8 % hmot, chrómu, 0,2 až 2,5 % hmot, práákovej médi, 55 až 75 % hmot, železného prážku, 0,4 až 2,5 % hmot,bentonitu, 0,1 až 2 % hmot. hlinika, 0,01 až 0,9 % hmot. kremika. Vyššie uvedenánáplně rúrkových držřtov nevedla zabezpečit zvýšenú priemernú húževnatosf návaro-vého kovu, vyžžiu odolnost voči abrazivnemu opotrebeniu abraziou a dostateční?tvrdost.Welding with alloyed tubular drills has gained great importance in the last period, due to the simpler manufacture of alloyed tubular drums for automatic welding as compared to alloyed solid drots. Maybe they get a wide range of surfacing metal compositions. The fillings of known steel tubular shafts intended for the coating of waterproofing layers, especially against abrasive and erosive wear, contain in one case 40 to 50% by weight of ferro-chromium, 1 to 5% by weight, ferrovanadium, 8 to 12% by weight, ferro-titanium, 2 % to 16 wt. ferro molybdenum and residual iron. In the other case, the fill contains 3 to 5% by weight of graphite, 8 to 15% by weight. % of tungsten, 2 to 4 wt. % of ferro-boron, 1 to 4 wt. Ferovanada, Oaláia filling according to SSR AO No. 226 585 contains 1.3 to 4% by weight, ferro molybdate, 1 to 4% of ferro-manganese, 1 to 4% by weight, sodium fluorosilicate, 14.1 to 19.8% by weight, chromium, 0, 2 to 2.5% by weight, of a scrubbing medium, 55 to 75% by weight, an iron powder, 0.4 to 2.5% by weight, bentonite, 0.1 to 2% by weight. % aluminum, 0.01 to 0.9 wt. kremika. The above-mentioned tubular holders have not been able to provide an increased average toughness of the weld metal, will provide abrasion resistance to abrasion and sufficient hardness.

Tieto nedostatky do značnej miery odstraňuje náplň trubičkového ocelovéhodrotu podle vynálezu, ktorý obsahuje 6 až 16 % hmot. ferowolfrámu, 4 až 10 % hmot.feromolybdánu, 1 až 4 % hmot, feromangánu, 1 až 5 % hmot, fluorokřemičitanu sodné-ho, 0,2 až 4 % hmot, práákovej médi, pričom podstata vynálezu spočívá v tom, ženáplň obsahuje čalej 5 až lo % hmot. feronióbu, 15 až 28 % chrómu, 2 až 8 % hmot. ferobóru, 15 až 25 % silikokarbidu, 6 až 12 % hmot, grafitu, 14až 22 % hmot, železného prášku. Náplň trubičkového ocelového drotu podlá vynálezu vykazuje velmi dobré tech-nologické vlastnosti už prl výrobě, keó neobsahuje hygroskopické zložky. Náplňtrubičkového drotu sa pri redukcii dobře zhutni a v procese navárania odpadá vy-sýpanie náplně, κ tomu prispieva koeficient zaplnenia 38 až 42 % a zrnitost zlo-žiek v rozmedzi 0,06 až 0,315 mm. Rúrkový ocelový dr3t je vhodný pre automatickésposoby navárania v ochraněkplynov, pod tavivom a elektroskovým sposobom. Návarovýkov dosahuje vyššiu odolnost voči abrazii ako je u AO č. 226 585 až o 20 %.These drawbacks are largely eliminated by the charge of the tubular steel scrap according to the invention, which contains 6 to 16 wt. ferro-tungsten, 4 to 10% by weight of ferro molybdenum, 1 to 4% by weight, ferro-manganese, 1 to 5% by weight, sodium fluorosilicate, 0.2 to 4% by weight, of the powdered medium, 5 to 10 wt. % of chromium, 15 to 28% chromium, 2 to 8 wt. ferroborous, 15 to 25% silicocarbide, 6 to 12 wt%, graphite, 14 to 22 wt% iron powder. The filling of the tubular steel wire according to the invention has very good technological properties already in the production process, since it does not contain hygroscopic components. The filling of the tubular pulp is compacted in the reduction process and the filling process is eliminated in the welding process, thereby contributing to a filling factor of 38 to 42% and a particle size distribution of 0.06 to 0.315 mm. The tubular steel dr3t is suitable for automatic welding applications in the protection of gas, under flux and electroslag. The welders reach up to 20% more abrasion resistance than AO 226 585.
