Casting: 88 Mesh (90% SiC) vs . 90 Mesh (88% SiC): Qhov zoo dua rau Cast Iron Inoculation? Vim li cas?
Hauv kev tsim cov hlau cam khwb cia,lig inoculation - ntxiv nucleating agents ua ntej pouring - refines graphite qauv, txo txias, thiab txhim kho txhua yam khoom. Silicon carbide (SiC) yog qee zaum siv los ua inoculant lossis adjuvant, tab sis nws cov txiaj ntsig zoo nyob ntawmmesh loj(particle loj) thiabkev huv(SiC cov ntsiab lus).
Ib qho kev sib piv tshwm sim ntawm88 mesh (≈90% SiC)thiab90 mesh (≈88% SiC). Thaum lawv zoo li cov lej, covmesh-tus naj npawb vs. purity txawvhloov lawv coj li cas hauv cov yaj.
NtawmZhenAn, nrog30 xyoo ntawm kev paubKev muab SiC rau cov ntawv thov kev tsim, peb piav qhia uas ua haujlwm zoo dua rau cov hlau cam khwb cia thiab yog vim li cas.
1. Inoculation Mechanism & Time Window
Inoculation ua hauj lwm los ntawm kev qhia nuclei rau graphite nag lossis daus thaum lub sij hawm solidification. Cov ntsiab lus tseem ceeb:
Yuav tsum tshwm sim sai ua ntej nchuav(feem ntau 1-3 min rau grey hlau) yog li nuclei muaj sia nyob mus rau solidification.
Dissolution tus nqintawm cov inoculant txiav txim siab ntev npaum li cas Si thiab C muaj nyob.
Kev tawg sai dhau → luv luv- nyob nyhuv; qeeb dhau → Si tsis txaus ua ntej khoom pib.
Yog li,particle lojtswj dissolution ceev, thiabkev huvtswj tau npaum li cas Si thiab C raug tso tawm rau ib chav tsev loj.
2. Mesh Loj: 88 vs . 90 - Qhov txawv yog dab tsi?
Mesh tooj=tus naj npawb ntawm qhov qhib ib nti.
88 mesh≈ 180 µm particle txoj kab uas hla
90 mesh≈ 170 µm particle txoj kab uas hla
Qhov sib txawv zoo li me me, tab sis hauv kev xyaum ua:
88 meshparticles yog marginallyloj dua→ qeeb qeeb qeeb me ntsis
90 meshparticles yog marginallyme me→ sai dua me ntsis dissolution
Hauv inoculation,qeeb qeebtuaj yeem ua tau zoo vim tias nws ncab lub sijhawm nucleation zoo nyob rau hauv qhov txwv nchuav qhov rai.
3. Purity: 90% SiC vs . 88% SiC - Kev cuam tshuam rau Inoculation
88 mesh (90% SiC): Cov ntsiab lus SiC siab dua txhais tau tiasntau Si + C ib grammuaj rau nucleation. Tsawg impurities (silica, dawb C) uas tuaj yeem cuam tshuam nrog kev tsim graphite lossis tsim cov khoom qis- melting compounds.
90 mesh (88% SiC)Cov ntsiab lus qis SiC → tsawg dua Si + C ib gram; ntau silica txhais tau tias qee Si yuav raug khi rau hauv SiO₂, txo cov Si dawb dawb rau graphite nucleation. Tsis tas li ntawd, cov theem impurity siab dua tuaj yeem hloov pauv cov dej ntws los yog ua rau muaj kev cuam tshuam.
Kev tshwm sim: 90% SiC tso tawm ntau dua Si thiab C, txhim kho nucleation muaj peev xwm.
4. Kev sib xyaw ua ke: Qhov twg zoo dua rau Cast Iron Inoculation?

Qhov xwm txheej |
88 Mesh (90% SiC) |
90 Mesh (88% SiC) |
|---|---|---|
|
Particle Loj |
me ntsis loj → qeeb qeeb |
Me ntsis me ntsis → sai dua |
|
SiC Purity |
Siab dua → zoo dua Si + C rau ib pawg |
Tsawg → tsis zoo, ntau impurities |
|
Nucleation Duration |
Ntev dua - ua yeeb yam hauv yaj |
Shorter - ua yeeb yam |
|
Risk ntawm Undissolved Residue |
Me ntsis siab dua (tab sis tuaj yeem ua raws li cov khoom nuclei) |
Tsawg dissolution residue |
|
Inoculation Efficiency |
Siab dua(zoo dua Si uptake, ua haujlwm ntev dua) |
qis dua (hloov sai dua -tawm, Si muaj tsawg) |
Xaus: 88 mesh (90% SiC) feem ntau zoo duarau cam khwb cia hlau inoculation vim:
Kev tawg qeeb qeebhaum rau qhov nqaim inoculation lub sij hawm qhov rais.
Siab dua SiC puritymuab Si thiab C siv tau ntau dua, txhim kho graphite refinement.
Cov khoom uas tsis ua kom yaj tag tuaj yeem nyob hauv qhov chaw heterogeneous nucleation, txhawb cov nyhuv.
5. Kev txiav txim siab zoo
Ncuav Timing: Yog hais tias tuav lub sij hawm tom qab inoculation yog luv heev (<1 min), faster-dissolving 90 mesh might seem advantageous, but you sacrifice Si content and risk incomplete inoculation.
Hom hlau: Hauv ductile hlau nrog Mg kev kho mob, qeeb Si tso tawm ntawm 88 mesh (90% SiC) pab kom tsis txhob Mg poob los ntawm turbulence.
Kev sib xyaw ua ke: Qee qhov chaw tsim khoom siv sib xyaw (piv txwv li, feem ntau 88 mesh 90% SiC + minority finer) los kho qhov nkhaus nkhaus.
Nqi vs. Performance: 88 mesh 90% SiC yuav raug nqi me ntsis ntxiv rau ib kg, tab sis kev txhim kho inoculation efficiency tuaj yeem txo qhov tsis lees paub thiab nce cov khoom siv tshuab, muab kev lag luam zoo tag nrho.
6. Kev lag luam piv txwv
Ib tug grey hlau foundry ua hydraulic valve lub cev hloov los ntawm 90 mesh (88% SiC) rau 88 mesh (90% SiC):
Pom taufiner, ntau uniform graphite flakes
