Oxygen Ntaj Tooj LiabHais txog cov tooj liab ntshiab uas tsis muaj pa oxygen lossis ib tus deasaxidizer seem. Hauv kev tsim khoom thiab kev tsim khoom ntawm anaerobic tooj liab pas, ua tiav anaerobic tooj yog siv ua cov khoom siv raw rau ntau lawm thiab ua rau. Qhov zoo ntawm oxygen dawb tooj liab pas nrig ua los ntawm cov khoom zoo kuj zoo heev.
1. Kev kov yeej cov nrib pleb
Cov txheej txheem ntawm kev txo qhov ntsuas kub ntawm tus phab ntsa casting yog qhov qauv zoo dua tsim nyog them rau. Cov pwm pwm yog siv los ua cov tsos, cov hlau pellet xuab zeb yog siv raws li cov av nkos tub ntxhais yog txuas rau qhov chaw tso dej. Cov txiaj ntsig ntawm kev kov yeej cov nrib pleb yog pom tseeb heev.
2. Argon Gas Tiv Thaiv casting
Vim tias oxygen dawb tooj dawb muaj qhov muaj pa thiab kev tshoov siab, kev tiv thaiv yuav tsum tau noj rau cov kua tooj liab thaum nws tawm ntawm qhov cub thiab nchuav. Nitrogen thiab argon roj yuav siv tau. Nrog kev tiv thaiv kev sib cav sib ceg, cov ntsiab lus oxygen ntawm cov castings yuav luag tsis nce tsis yog nce los ntawm kaw cov txheej txheem.
3. Xaiv cov xim
Rau oxygen dawb tooj liab, nws yog qhov zoo dua los siv zirconium xim lossis tshuaj tsuag acetylene nplaim taws dub ntawm zirconium xim. Kev xyaum tau ua pov thawj tias lub ntsej muag sib xyaw nrog cov xim zoo li no, tsis muaj paib ntawm roj, thiab cov pa luam yeeb dub muaj deoxidation.
4. Kev siv ntawm cov hlau hom kub
Qhov ntsuas kub ntawm cov hlau pwm muaj cov nyhuv ntawm cov kab nrib pleb, ntom ntom, saum npoo ua tiav thiab subdermic pores ntawm lub casting. Nws tau raug pov thawj los ntawm kev xyaum uas siv qhov kub ntawm cov hlau pwm ntawm nchuav cov pa oxygen-dawb tau zoo dua ntawm 150 ℃.
5. Cov Txheej Txheem Ntsuas
Lub casting ntawm oxygen dawb tooj liab yog qhov nyuaj, thiab lwm yam kev tswj hwm ntawm cov kab ke tsis yog kev xaiv nrog kev xaiv tsim nyog ntawm kev ntsuas.
