Electrode Yovomerezeka Yothira Ma Welding E2594 Imapereka Magwiridwe Abwino Kwambiri a Duplex

Monga ogulitsa mafakitale odziwika bwino, timapereka satifiketiKuwotcherera maelekitirodi E2594(AWS A5.4 E2594-16), yomwe imatchedwa AF2594-16. Electrode iyi yachitsulo chosapanga dzimbiri yokhala ndi titanium calcium, yokhala ndi carbon yochepa kwambiri, imakhala ndi nayitrogeni wambiri kuti ipereke kukana dzimbiri kwapadera. Mankhwala ake apadera amapanga chitsulo chosungunula chomwe chimalimbana kwambiri ndi maenje, stress corrosion cracking (SCC), komanso thermal cracking.–Chofunika kwambiri makamaka m'malo okhala ndi chloride yambiri monga mafakitale opangira mankhwala ndi zomangamanga za m'nyanja komwe zitsulo zosapanga dzimbiri sizigwira ntchito bwino.

Elekitirodi'Kugwira ntchito bwino kwa chitsulo kumachokera ku kapangidwe kake kotsika ka kaboni (kawirikawiri <0.03% C) kophatikizidwa ndi nayitrogeni ndi molybdenum. Izi zimapangitsa kuti pakhale kusiyana kwa 2-40 pakati pa Pitting Resistance Equivalent (PRE) pomwe kumasunga kapangidwe ka austenite-ferrite koyenera. Kapangidwe kachitsulo kamaletsa dzimbiri pakati pa granules ndipo kamasunga kulimba kwa kugundana pakati pa kutentha kwa ntchito kuyambira pa cryogenic mpaka 300 C.°C (572)°F), nthawi zonse zimapitirira zofunikira za makina a AWS A5.4.

Pantchito, iziKuwotcherera maelekitirodi E2594Ili ndi utoto wokonzedwa bwino wa titanium-calcium womwe umatsimikizira kukhazikika kwabwino kwa DC+ arc ndikuchotsa slag m'malo onse, kuphatikiza kugwiritsa ntchito molunjika. Chophimbachi chimachepetsa kuyamwa kwa hydrogen (<5ml/100g), ndikuchotsa zoopsa zomwe zingachitike m'malo olumikizirana omwe ali ndi zoletsa zambiri. Olumikiza amanena kuti kusamutsa chitsulo chosalala ndi kudontha kochepa komanso kubwezeretsanso kosavuta, zomwe zimapangitsa kuti ntchito zikhale zofunikira kwambiri monga kupanga zombo zopanikizika ndi kuwotcherera mapaipi.

Kutsimikizira magwiridwe antchito kumatsimikizira kuti chitsulo chosungunula chimakhala ndi pafupifupi 25.5% Cr, 9.5% Ni, 3.8% Mo, ndi 0.22% N. Njira Yodziyimira Yokha ya ASTM G48 Kuyesa A kukuwonetsa kukana dzimbiri komwe kumapitirira magiredi wamba a duplex ndi 40°C (104)°F). Kulinganiza kwa gawo la ferrite-austenite lolamulidwa la 45/55 kumapereka mphamvu zokolola za 650-750 MPa (94-109 ksi) ndi kutalika kwa 25%+–kukwaniritsa zofunikira za ASME, EN, ndi NORSOK pa zomangamanga zofunika kwambiri.

Pa ntchito zovuta zowononga,Kuwotcherera maelekitirodi E2594Ikadali muyezo wa makampani. Kugwira ntchito kwake kotsimikizika mu machitidwe ochotsa mchere m'madzi, nsanja zakunja, ndi ma reactor a mankhwala kumatsimikizira kudalirika. Yoperekedwa m'mapaketi otsekedwa ndi vacuum a 4kg okhala ndi moyo wa miyezi 36, zipangizo zonse zimaphatikizapo ziphaso zapadera. Lumikizanani ndi gulu lathu laukadaulo kuti mudziwe zambiri za njira zowotcherera zomwe zimagwiritsidwa ntchito.
