Plaub lub hauv paus ntsiab lus rau kev xaiv cov khoom siv hluav taws xob cua sov yeeb nkab

1. Kev xaiv cov hlau tsis kam

Cov khoom siv hlau tsis kam siv feem ntau siv hauv cov kav hluav taws xob cua sov yog Fe-Cr-Al thiab Cr20Ni80 tsis kam xaim. Cov hlau-chromium hlau xaiv los ntawm KAWAI yog 0Cr25Al5, uas muaj cov ntsiab lus melting ntau dua li cov hlau-chromium zoo tib yam thiab muaj lub neej ua haujlwm zoo dua. Qhov sib txawv tseem ceeb ntawm ob txoj hlua hluav taws xob yog tias lub melting point ntawm 0Cr25Al5 yog siab dua li ntawm Cr20Ni80, tab sis ntawm qhov kub thiab txias, 0Cr25Al5 yog yooj yim rau oxidize, thaum Cr20Ni80 muaj peev xwm tuav ruaj khov kev ua tau zoo ntawm qhov kub thiab txias. Yog li ntawd, Cr20Ni80 feem ntau yog siv rau cov hlau tsis kam siv nyob rau hauv qhov kub thiab txias.

Qhov thib ob, cov qauv kev xaiv ntawm cov kav dej: corrosion kuj, kub kuj.

Rau cov raj kub kub, txhuas raj, BUNDY, thiab cov raj tooj liab feem ntau xaiv, thaum cov raj kub kub sib txawv. Ingle raj thiab stainless hlau raj feem ntau siv. Vim tias Ingle 840 hluav taws xob cua sov raj tuaj yeem muaj oxidation zoo heev thiab corrosion kuj nyob rau hauv kub kub ua hauj lwm tej yam kev mob.
