Qhov tshwj xeeb ntxiv piv ntawm silicon hlau 441 thiab 553 hauv kev lag luam metallurgical

Qhov tshwj xeeb ntxiv piv ntawm silicon 441 thiab 553 hauv kev lag luam metallurgical txawv nyob ntawm qhov sib txawv smelting lub hom phiaj thiab cov khoom siv hlau. Cov hauv qab no yog qee qhov xwm txheej:

Silicon 441

Steelmaking txheej txheem

Nyob rau hauv dog dig tua steel, 0.15%-0.30% Si feem ntau yog ntxiv, uas pab deoxidation thiab txhim kho cov hlau zoo.
Nyob rau hauv quenched thiab tempered structural steel, ntxiv 1.0% -1.2% Si tuaj yeem ua kom muaj zog ntawm 15% -20%.
Tsawg carbon steelmuaj 1% -4% Si muaj qhov sib nqus permeability ntau dua thiab tuaj yeem siv hauv kev lag luam hluav taws xob los ua silicon steel los xij.

Casting aluminium alloy

Tus nqi ntxiv yog kwv yees li 4% -13%, thiab qhov sib piv tshwj xeeb nyob ntawm qib thiab kev ua tau zoo ntawm aluminium alloy. Piv txwv li, nyob rau hauv ib co ntau casting txhuas alloys xws li ZL102, cov ntsiab lus silicon feem ntau yog 10% -13%, thiab silicon hlau 441 tuaj yeem siv los ua ib qho tseem ceeb ntawm silicon ntxiv.

Silicon hlau 553

Steelmaking txheej txheem

Nws qhov sib piv ntxiv yog zoo ib yam li Silicon Metal 441, tab sis vim yog cov ntsiab lus tsis huv, qhov sib ntxiv yuav raug rau qee qhov kev txwv ntawm qee qib steel nrog cov kev xav tau purity siab dua. Hauv kev tsim cov hlau zoo tib yam, qhov sib ntxiv yuav nyob ib puag ncig 0.15% -0.60%.

Kev lag luam Foundry

Thaum casting cam khwb cia hlau, qhov sib ntxiv ntawm Silicon 553 feem ntau yog nyob ib ncig ntawm 0.5% -3%. Piv txwv li, thaum tsim grey cam khwb cia hlau, thiaj li yuav txhim kho lub zog thiab hardness ntawm lub casting, 1% -2% ntawm Silicon 553 tej zaum yuav ntxiv; Thaum tsim cov hlau nplaum, qhov sib ntxiv yuav nyob ib ncig ntawm 0.5% -1.5%.

FAQ

Q: Kuv qib steel xav tau 0.20-0.35% silicon. Cov nqi hluav taws xob twb muaj 0.10% silicon. Kuv xav tau 553 steel ntau npaum li cas?

A: Koj yuav tsum tau ntxiv 0.10-0.25% silicon. Piv txwv li 75% silicon cov ntsiab lus thiab 8% poob ntawm kev kub hnyiab rau 553 steel: Ntxiv nyiaj=0.25% ÷ 75% × 1000 × 1.08 ≈ 3.6 kg / ton ntawm steel. Nws raug nquahu kom sim cov khoom me me ua ntej thiab kho kom haum tom qab kev tshuaj xyuas.

Q: Ntau npaum li cas kim dua yog 441 steel piv rau 553 steel rau A356 log? Puas tsim nyog nws?

A: A356 muaj cov ntsiab lus silicon ntawm 6.5-7.5%, yuav tsum tau ntxiv 65-75 kg ib ton ntawm txhuas. 441 yog 500 yuan kim dua ib tuj tshaj 553, nce tus nqi ib tuj ntawm txhuas los ntawm 30-35 yuan. Txawm li cas los xij, 441 muaj cov ntsiab lus hlau qis (0.4%) tshaj 553 (0.5%), ua rau 10-15% siab dua elongation. Rau high-end log, peb cov neeg muas zaub paub qhov zoo; nws tsim nyog nws.

Q: Puas yog cov ntsiab lus silicon ntawm koj cov khoom 441 thiab 553 hloov pauv ntau ntawm cov khoom siv?

A: Peb sim txhua batch ua ntej nws tawm hauv lub Hoobkas, thiab cov ntsiab lus silicon hloov pauv yog tswj tsis pub dhau ± 0.5%. Piv txwv li, cov ntsiab lus silicon ntawm 553 peb muab rau koj yog nruab nrab ntawm 98.0% thiab 99.0%. Cov ntaub ntawv xeem tau suav nrog cov khoom xa tuaj.
