1. Dab tsi yog qhov tseem ceeb tshuaj lom neeg ntawm cov nickel - raws li alloys?
Teb:
Alloy 625 (tsis yog N06625): ~ 58% ni, 20-23% cr, 8-10% mo, me me ntawm FE thiab NB.
Alloy 718 (tsis yog n07718): ~ 52-55% ni, 17-21% mo, 4.7% NB + TA, nrog FE thiab TI.
Alloy 725 (Tsis yog N07725): ~ 57% ni, 20-23% mo, ib yam li 625 tab sis muaj lub zog me ntsis.
Cov alloys no yog tsim los rau high - kub lub zog, corrosion tsis kam, thiab mechanical reliability.
2. Dab tsi yog cov ntawv thov ntawm cov kav dej seamless no?
Teb: Lawv tau siv rau hauv lub tshuab ua kua, ntsuas tshuaj, thiab cov cuab yeej siv hluav taws xob uas muaj zog, kub ua yog qhov tseem ceeb.
3. Vim li cas cov kav dej seamless
Teb: Seamless kav tsis muaj Welds, uas muab cov kev pheej hmoo tsis txaus ntseeg, qhov kub thiab txias, thiab cyclic chaw thau khoom muaj cov hauv kev.
4. Dab tsi yog "kev cai loj 24 nti" txhais tau tias cov kav dej no?
Teb: nws qhia tau tias cov chaw tsim khoom tuaj yeem tsim cov kav dej uas muaj lub plawv uas yuav tsum muaj, los ua kom pom tseeb kom haum thiab ua yeeb yam hauv cov sib dhos Turbine sib dhos.
5. Yuav ua li cas cov nickel - based alloy kav hlau yuav muab khaws cia thiab khi?
Teb: Muab cia rau hauv ib qho chaw huv, qhuav kom tiv thaiv kev paug lossis oxidation. Kov nrog kev saib xyuas kom tsis txhob khawb, dents, lossis khoov, raws li kev puas tsuaj saum npoo yuav txo corrosion tsis kam thiab kho tshuab kev ncaj ncees.
