Inoculants thiab Nodulizers feem ntau yog siv hauv kev ua pov. Dab tsi yog qhov sib txawv thiab kev sib txuas ntawm inoculants thiab Nodulizers? Cia peb tham txog cov chaw tsim khoom ntawm cov inoculants thiab Nodulizers:
Taw qhia rau inoculants:
Inoculant yog ib hom neeg sawv cev uas tuaj yeem txhawb kev kho hniav ntawm cov tshuaj ntxuav hniav, txhim kho cov pab pawg, thiab ua kom zoo dua cov qauv sib dhos. Nws muaj cov nyhuv nyob rau lub sijhawm luv luv (txog 5 {{{{}} 8 feeb) tom qab kev kho mob inoculation. Cov nyhuv zoo. Feem ntau haum rau cov xwm txheej dav dav lossis cov theem qis dua hauv ntau lub sijhawm.
Ferrosilicon inoculant Silicon Barium Chij Inoculant
Inoculation kev kho kom ntxiv cov tshuaj me me rau cov khoom siv ua kua thaum lub hom phiaj loj hlob, inhibit kev loj hlob, thiab ua tiav lub hom phiaj ntawm refining cov nplej. Kev lig kev cai, ntxiv cov quav ntxiv los nrum hlau yog hu ua Inoculation Inoculation; Ntxiv cov tshuaj ntxiv rau tsis- ferrous alloys yog hu ua kev kho hloov. Hauv cov ntsiab lus, kev kho mob inoculation feem ntau cuam tshuam nucleper thiab txhawb nqa cov qoob loo discociation; Thaum kev kho mob me me hloov kho cov tshuab kev loj hlob ntawm cov muaju (inhibiting kev loj hlob), yog li cuam tshuam cov crystal morphology.
Inoculant nyhuv:
Ua kom muaj kev nce qib teeb, ua kom tau cov duab ntxiv, txhawb nqa ntawm - hom graphite, thiab txhim kho lub zog. Rau cov yas hlau castings, nws tuaj yeem ua rau graphite hauv cov hlau loj thiab puag ncig, thiab txhim kho qib spheroidization.
Nws tuaj yeem txo cov qib supercooling ntawm molten hlau, txhawb kev ua kom zoo nkauj ntawm graphite, txo cov kev sib cav sib ceg, thiab txhim kho kev txiav txim siab ntawm cov castings.
Muaj zog anti - kev muaj peev xwm. Lub isti {- reaesses lub sij hawm yog ob zaug uas 75 silicon. Qhov kev sib ntxiv ntawm Barium silicon inoculant yog tsawg dua li ib nrab ntawm xyoo 75 ferrosilicon inoculant, thaum tiv thaiv kev sib txuam nrog kev sib txawv.
Lub phab ntsa tuab yog qhov tsis tshua rhiab, txhim kho kev hnav khaub ncaws sib txawv ntawm qhov chaw hla thiab txo cov nyiam ntawm shrinkage thiab porosity.
Cov tshuaj lom neeg muaj zog yog ruaj khov, kev ua cov khoom loj me me yog cov khaub ncaws loj, thiab muaj pes tsawg leeg thiab kev sib txawv yog me me.
Lub ntsiab lus melting yog tsawg (qis dua 1300 degree), uas ua rau nws yooj yim kom nqus tau yaj thaum lub sij hawm inoculation thaum lub sij hawm inoculation thaum lub sij hawm inoculation thiab muaj cov dross heev.
Taw qhia rau Nodulizer:
Kuj hu uaLub ntiaj teb tsis tshua muaj zog magnesium ferro -} silicon alloy, nws yog ib qho ntxiv ntxiv uas tuaj yeem txhawb nqa cov crystallization ntawm graphite hauv cov hlau cam khwb cia hlau rau hauv spherical duab. Nws feem ntau yog siv nyob rau hauv daim teb ntawm cov hlau cam khwb cia. Thaum lub sij hawm ua cov txheej txheem casting, cov khoom ntxiv ntxiv rau cov hlau nplaum molten rau daus, thiab muaj lub ntiaj teb tsis tshua muaj npe ntawm cov khoom tsis tshua muaj lub ntiaj teb no
Txoj haujlwm ntawm nodulizer:
Spheroidization: Ua kom yoojyim graphite rau hauv cov duab kheej kheej
Anti {- kev ploj nyiaj, tso cai rau cov spherical graphite kom nyob twj ywm deformed rau lub sijhawm ntev
Daim ntawv thov noalulizer:
Nodulizing tus neeg saib xyuas, vermicularizing tus neeg sawv cev thiab inoculant rau cam khwb cia hlau. Tsis tshua muaj lub ntiaj teb
Ntxiv rau steelmaking: lub teeb tsis tshua muaj cua sov magesium ferrosilicon alloy siv nyob rau hauv kev tsim cov khoom sib ntxiv thiab cov neeg sawv cev hauv cov hlau thiab hlau. Siv rau kev ua kom zoo nkauj, deoxidation, nruab nrab ntawm cov ntsiab lus tsis zoo nrog cov khoom siv hlau tsis muaj zog ntxiv los ntxuav cov hlau ua kom huv;
Hauv ntej, cov inoculant tsuas yog txhawb nqa graphitization, txo cov whitening li, txhim kho cov graphite, nce tus naj npawb ntawm cov pawg Eutectic, thiab kho cov qauv sib luag. Nodulizer tuaj yeem txhawb nqa lub crystallization ntawm graphite hauv pob - milled cam khwb cia hlau rau hauv cov duab puab.
