Nyob rau hauv "qhov hluav taws kub" ntawm lub dav hlau cav lossis roj turbines, cov kav dej yog qhov sib txuas yooj yim tshaj plaws. Cov ntsiab lus mob tseem ceeb rau aerospace engineers thiab kho, kho, thiab kho dua tshiab (MRO) cov kws tshaj lij suav nrog:
Phab ntsa thickness eccentricity:Qhov sib txawv ntawm concentricity tsim "thin me ntsis" hauv cov yeeb nkab phab ntsa. Hauv qab - siab thermal cycling (txog800 degree), cov pob me me no tuaj yeem ua qhov pib ntawm cov yeeb nkab tawg, ua rau muaj kev puas tsuaj loj heev.
Lwm txoj kev pheej hmoo:Siv "kev lag luam-qib" nickel alloys tsis muajVIM+ESRdual lub tshuab nqus tsev refining txheej txheem yuav tsum tau rau lub davhlau kev nyab xeeb Cheebtsam.
NtawmGnee Alloy, peb muab xoom- cov kav dej xau. PebGH3030 tubingyog tsim tshwj xeeb los tswj cov qauv kev ncaj ncees nyob rau hauv qhov xav tau tshaj plaws aerospace ib puag ncig.

Siab -kub seamless tubing rau GH3030 turbocharged cav
Siab -kub seamless tubing rau GH3030 turbocharged cav
GH3030 seamless steel yeeb nkab yog ib qho kev daws teeb meem - muaj zog 80Ni / 20Cr siab - kub alloy. Nws yog qhov tsim nyog rau turbocharged engine ib puag ncig, nthuav tawm oxidation zoo heev thiab thermal qaug zog tiv thaiv, nrog rau qhov kub ntawm 800℃txog 1100 degree. Nws yog ib qho kev xaiv zoo tshaj plaws rau siab - qhov kub thiab txias combustor Cheebtsam, cov kav dej tso pa, thiab cov thermocouple vaj tse.
Dab tsi yog cov khoom ntawm GH3030?
GH3030 yog ib qho kev daws teeb meem ntxiv dag zog rau siab - kub alloy, feem ntau yog tsim los ntawm npib tsib xee (Ni) thiab chromium (Cr), nrog rau cov tshuaj lom neeg yooj yim. Nws qhov piv txwv yog 80% npib tsib xee thiab 20% chromium.
