Kev tshuaj xyuas kev yuav khoom thiab kev yuav khoom rau Nimonic 75
Nimonic 75 yog 80/20 npib tsib xee-chromium alloy ntxiv dag zog los ntawm kev sib ntxiv ntawm titanium thiab carbon. Nws yog ib qho kev daws teeb meem ntxiv dag zog rau siab -kub superalloy tsim los rau siab - cov ntawv siv kub zoo li qub, nthuav tawm cov oxidation zoo heev, nplai tsis kam, thiab lub zog zoo txhua yam.
Cov tshuaj muaj pes tsawg leeg ntawm NIMONIC 75 yog dab tsi?
Nimonic 75 (UNS N06075) yog 80/20 npib tsib xee-chromium alloy. Nws cov ntsiab lus tseem ceeb yog npib tsib xee, nrog cov ntsiab lus chromium ntawm 18.0% -21.0%, thiab me me ntawm titanium thiab carbon. Nws muaj qhov ua tau zoo oxidation tsis kam thiab siab - qhov kub thiab txias, thiab feem ntau yog siv rau hauv cov roj turbines thiab cov khoom siv hluav taws xob. Nws kuj muaj me me ntawm hlau, silicon, thiab manganese.

4. Peb -Txoj Kev Them rau Kev Txo Cov Kev pheej hmoo ntawm kev yuav khoom
Kauj Ruam 1: Txheeb xyuas cov txheej txheem Melting
High -Nimonic 75 zoo yuav tsum tau tsim los siv ibNqus induction melting (VIM) + electroslag remelting (ESR) txheej txheem. Thov cov ntaub ntawv furnace los ntawm tus neeg muag khoom. Qhov no ua kom ntseeg tau tias ultra- cov ntsiab lus tsis muaj sulfur thiab xoom macroscopic cais.
Kauj Ruam 2: Txheeb Xyuas Daim Ntawv Pov Thawj (MTC 3.1)
Xyuas kom lub Hoobkas kuaj daim ntawv pov thawj ua rawsEN 10204 3.1. Daim ntawv pov thawjyuav tsum suav nrog tus lej ntawm lub tshuab hluav taws xob, tshuaj lom neeg cov tshuaj ntsuam xyuas, qhov loj ntawm cov nplej, thiab cov khoom siv ntsuas qhov ntsuas ntawm qhov kub thiab txias.
Kauj Ruam 3: Txiav Txim Tsis Tau -Kev Ntsuas Kev Ua Phem
Rau round bars thiab raj,100% ultrasonic kuaj (UT)thiabeddy tam sim no xeem (ET)yuav tsum tau. Qhov no zam cov nqi siab uas cuam tshuam nrog kev tshawb pom sab hauv voids tom qab ua cov hlau tuav.

FAQ
Q1: Nimonic 75 puas tuaj yeem siv los ua qhov poob - hloov rau Lavxias EI435 (ЭИ435)?
A:Yog lawm. Qhov tseeb, feem ntauAerospace MROcov chaw hauv Is Nrias teb thiab CIS lub teb chaws siv lawv sib pauv. PebGH3030 / Nimonic 75 sib npaugyog tsim tshwj xeeb los txuas rau qhov sib txawv ntawm tus qauv no, muab qhov zoo sib xws oxidation tsis kam mus txog 800 degree.
Q2: Vim li cas Tuam Tshoj Hoobkas - tus nqi ncaj qha 30-40% qis dua Western stockists?
A:Los ntawm kev tshem tawm thoob ntiaj teb cov neeg nruab nrab markups thiab nrhiav ncaj qha los ntawm aTuam Tshoj superalloy Hoobkas, koj tau txais txiaj ntsig los ntawm kev ua kom zoo tshaj plaws hauv zos cov nqi tsim khoom thiab kev lag luam loj, tsis muaj kev cuam tshuam rauASTM lossis AMS cov qauv.
Q3: Lub sijhawm ua khoom lag luam yog dab tsi?
A:Peb tuav akhoom lojntawm qhov loj me rau kev xa tawm thoob ntiaj teb tam sim (7-10 hnub). Kev cai fabrication los yog tsis-tus qauv qhov ntau thiab tsawg feem ntau xav tau 30-45 hnub.
