Nyob rau hauv lub teb ntawm foundry thiab steelmaking, carburizer zoo ncaj qha cuam tshuam hlau kev ua haujlwm thiab cov nqi tsim khoom. Tuam Tshoj txoj kev ua piv txwv Ningexia tau dhau los ua tus qauv kub rau cov neeg mob carburizers thoob ntiaj teb vim nwsTshwj Xeeb Cov HeCol Carbon, Ultra-Low Sulphur, thiab Minimal Cov Tshauv Tsoo- Tseem ceeb outperforming imported alterned adportives (piv txwv li, los ntawm Russia lossis North Kauslim) hauv kev ntsuas cuav. Qhov kev ntsuas no kuaj ningexia Anexia Anthplaceable tus nqi dhau los ntawm cov ntaub ntawv tshawb fawb thiab kev siv khoom lag luam.
I. Ningxia Anthracite thiab Txawv Teb Chaws: Cov Lus Tseem Ceeb

Kev sib tw zoo:
Ntiaj teb siab tshaj plaws cov ntsiab lus carbon siab(88% +) → 15-20% Ntau Carburizing efficiencing
Tsawg tshaj plaws Sulphur(Tsawg dua los yog sib npaug rau 0.3%) → tiv thaiv sulfur embrittlement, zoo tagnrho rau cov hlau ductab
Minimal tshauv(Tsawg dua los yog sib npaug rau 5%) → txo cov swb thiab kev tu tus nqi
Zoo Dua(92% +) → Date Fast (5-8 feeb), Zog-txuag
Ii. Muaj nqi ntawm ningxia anthracite carburizer
1. Cov ntawv thov hwm tau zoo
Zas Hlau: Sulfur tsawg dua lossis sib npaug rau 0.3% kom ntau dua lossis sib npaug ntawm 90% nodularization, txo shrinkage
High-qib grey hlau(Ht {250+): stabilizes hom graphite, +10} lub zog tensile
Hlau Casting: Carbon Fribied tsawg dua lossis sib luag rau 0.05%, zoo meej rau cov khoom ntsuas hluav taws xob (piv txwv li cov khoom siv cav)
2. Cov txiaj ntsig me me
EAF Steelmaking: Hloov 30% Hlau Hlau, txuag ¥ 200-300 / tuj
Tus hlau loj: Ultra-Low S / N Ua Purity Yuav Tsum Purity Yuav Tsum Tau Rau Cov Menyuam / Pwm Hlau

III. Kev Pab Cuam: Vim li cas nws yog irreplaceable
Tsis muaj qhov txawv teb chaws geology:
Tsim nyob rau hauv carboniferous-permian lub sij hawm nrog metamorphism → ze-graphite crystallinity
Lavxias / n.Korean cov nyiaj tau los yog geologically yau (Jurassic) nrog tsawg cov roj carbon
Ua Ntej Ua:
Ningexia'skev hloov dua tshiab(1200℃→ 1500 degree) kom paub meej txog kev tshem tawm leej faj
Cov khoom siv carburizers txawv teb siv ib-ntsuas kub recination → ntau dua cov tub rog sab nraud
Kev Ua Raws Ib puag ncig:
Lawm Tsawg Sulphur tsis txhob siv tshuaj lom neeg desulfurization
Cov thee ntawm cov thee kom siv cov roj qaub → Cov nqi kho mob pov tseg ntxiv
IV. Kev Lag Luam Lag Luam Thoob Ntiaj Teb
Qhia Tawm: 65% ntawm Tuam Tshoj tus carburizer xa tawm (2023 cov ntaub ntawv)
Hwm cov lag luam: Tsim los ntawm Mercedes-Benz / BMW Cov Khoom Siv Hluav Taws Xob
Qauv: Ningxia Txuj Ci (NX / T 046-2021) tau txais raws li cov siv thoob ntiaj teb
