Description
Vynález sa týká drótu na zváranie nízkolegovaných žiaruvzdorných ocelí metodou TIG, určených najmá pre zariadenia parogenerátorov rýchlých reaktorov.The invention relates to a wire for welding low-alloy refractory steels by the TIG method, intended in particular for steam generator generators of fast reactors.
V toohnickej praxi sa často vyskytujú případy zvárania nízkolegováných žiaruvzdorných ocelí. Na tieto účely sa odporúčajú rózne druhy elektrod pre ručné oblúkové zváranie. Získán i e zvarového spoja požadovanej kvality na zariadení zaradenom v jeden oelok z nízkolegovanej aj vysokolegovanej ocele, ktoré praouje tak, že to isté chladiace médium priohádza do styku s častami zariadenia z dvoch typov ooelí, pričom nemá dójsť ku korózii časti z vysokolegovanej ooele, vyžaduje Specifická koncepoiu chemického zloženia základného materiálu a chemického zloženia zvarového kovu. Bez čpeoifickej úpravy přídavného materiálu - elektrody, drótu - dochádza ku korózii častí zariadenia vyrobených z vysokolegovaných ocelí.In Toohnic practice, there are often cases of welding low-alloy heat-resisting steels. For this purpose, different types of electrodes for manual arc welding are recommended. To obtain a welded joint of the required quality on a low-alloy and high-alloy steel unit which flows in such a way that the same coolant comes into contact with parts of the two-type steel, without corrosion of the high-alloy ooele, requires specific the chemical composition of the base material and the chemical composition of the weld metal. Without a specific modification of the filler material - electrode, wire - parts of the device made of high-alloy steels are corroded.
Uvedené nevýhody sa do značnej miery odstránla drótom na zváranie nízkolegovanýoh ooelí metodou TIG, podlá vynálezu. Podstata drótu, ktorý obsahuje 0,01 až 0,08 $ hipot .uhlíka,These disadvantages have been largely eliminated by the low-alloy welding wire of the TIG method of the invention. The essence of a wire containing 0.01 to 0.08 $ hippocarbon,
0,60 až 1,20 % hmot.manganu, 0,30 až 0,50 % hmot.kremíka, podlá vynálezu spočívá v tom, že ňalej obsahuje 2,00 až 2,40 jé hmot, ohromu, 0,60 až 0,90 jé hmot «niklu, 0,40 až 1,00 jé hmat, molybdénu, 0,10 až 0,65 % hmot,niobu a zvyšok tvoří železo.0.60 to 1.20% by weight of manganese, 0.30 to 0.50% by weight of silicon according to the invention, characterized in that it further comprises 2.00 to 2.40% by weight, 90% by weight of nickel, 0.40 to 1.00% of tactile, molybdenum, 0.10 to 0.65% by weight, niobium and the remainder being iron.
Výhodou drótu na zváranie nízkolegováných žiaruvzdorných ooelí metodou TIG je, že zamedzuje nauhličovanie a tým zároveň aj vznik korozie vysokolegováných častí energetických zariadení, pričom drót má dobré zváraoie vlastnosti a dosahujú sa požadované mechanické vlastnosti zvarového kovu.The advantage of the TIG wire for welding low-alloy refractory clay is that it prevents carburizing and thus also corrosion of high-alloy parts of power equipment, while the wire has good welding properties and achieves the desired mechanical properties of the weld metal.

Podlá vynálezu bol vyrobený drdt na zváranie nízkolegovaných žiaruvzdorných ocelí metodou TIG, ktorý obsahoval 0,018 i» hmot.uhlíka, 0,80 % hmot .mangánu, 0,31 % hmot,kremíka, 2,28 % hmot.chrómu, 0,75 % hmot.niklu, 0,6 % hmot.molybdénu, 0,44 % hmot.niobu a 96,802 $ hmot.železa.According to the invention, a TIG welding wire of low alloy refractory steels was produced which contained 0.018% by weight of carbon, 0.80% by weight of manganese, 0.31% by weight of silicon, 2.28% by weight of chromium, 0.75% by weight % nickel, 0.6 wt.% molybdenum, 0.44 wt.% niobium, and 96.802 wt.% iron.
Drdt podlá vynálezu umožňuje zhotoviť zvary, ktoré znižujú koróziu přenosom pracovného média hlavně tým, že použitý niob zabezpečuje stabilizáciu uhlíka vo zvarovom kove nízkolegovanej žiaruvzdornej ocele.The drtt according to the invention makes it possible to produce welds that reduce corrosion by transferring the working medium mainly by using the niobium used to stabilize the carbon in the weld metal of the low-alloy heat-resistant steel.
Optimálny obsah niobu v drdte podía vynálezu sa stanoví na základe obsahu uhlíka a dusíka vo zvarovotů kove takto : hmotnostně % Nb = 7,75 x hmotnostné % C + 6,64 x hmotnostně % N.The optimum niobium content of the crumb according to the invention is determined on the basis of the carbon and nitrogen content of the metal weldments as follows:% by weight Nb = 7.75% by weight C + 6.64% by weight N.
Drdt podía vynálezu má velmi dobré operativně aj metalurgické vlastnosti.The drtt according to the invention also has very good operational and metallurgical properties.
Zvarový kov získaný drdtom podía vynálezu mal následovně mechanické vlastnosti :The weld metal obtained by the crumb according to the invention had the following mechanical properties:
Rp 0,2 = 427 MPaRp 0.2 = 427 MPa
Rm = 555 MPaR m = 555 MPa
A5 % = 15,8 % *2A5% = 15.8% * 2
KCV s 68 J.cm / priemer z troch vzorkov /KCV with 68 J.cm / average of three samples /
Vyvinutý drdt bol použitý pri modelových skúškach zariadenia parogenerátorov rýohlýoh reaktorov.The developed drdt was used in model tests of steam generator generators of boilers.
