Dub Carburizer rau Casting

Lub recarburizer, feem ntau hu ua carbon raiser los yog GPC (Graphitized Petroleum Coke), yog carbonaceous additive siv nyob rau hauv foundries thiab steel mills. Nws lub luag haujlwm tseem ceeb yog txhawm rau nce cov ntsiab lus carbon ntawm cov hlau molten lossis hlau thaum tsim khoom. Tsis zoo li cov ntsiab lus alloying uas nthuav tawm cov khoom tshiab, cov pa roj carbon yog lub hauv paus ntsiab lus, txhais cov tub ntxhais lub zog, hardness, thiab castability ntawm cov khoom hlau kawg. High-cov khoom siv rov ua tau zoo muaj cov txheej txheem ua tau zoo thiab tswj tau kom ua tiav cov pa roj carbon zoo kawg nkaus, ua kom cov khoom siv hlau sib xws thiab kev ntseeg tau ntawm cov khoom.

Tsis yog txhua tus recarburizers raug tsim sib npaug. Nyob ntawm cov khoom siv raw thiab cov txheej txheem tsim khoom, lawv sib txawv ntawm cov pa roj carbon purity, cov ntsiab lus sulfur, thiab tus nqi nqus. Nov yog cov hom tseem ceeb:

Calcined Petroleum Coke (CPC)
🚢 Siv dav vim muaj thiab pheej yig. Nws muaj cov ntsiab lus ntawm cov pa roj carbon monoxide thiab kev nqus tau zoo.

Graphitized Petroleum Coke (GPC)
⚡ Ua los ntawm qhov kub thiab txias, hom no muaj ntau dua purity, tsis muaj leej faj, thiab nqus sai dua.

Calcined Anthracite Coal (CAC)

Paub txog nws qhov hardness thiab siab carbon yield, txawm tias nws qhov nrawm nrawm dua.

Synthetic Graphite
🧪 Kev xaiv hwm. Siab hauv cov pa roj carbon ntau (txog 99%) thiab zoo tagnrho rau qhov tseem ceeb-qib castings lossis siab- steel kev ua tau zoo.

Carbon yog ib qho kev ua si - hloov pauv hauv metallurgy. Nws influences:

• Hardness & Lub zog 💪
• Hnav Resistance 🔧
• Machinability 🛠️
• Castability 🏗️

Cov pa roj carbon tsawg dhau tuaj yeem ua rau cov khoom nkig lossis tsis muaj zog, thaum ntau dhau tuaj yeem ua rau cov slag ntau dhau los yog qhov tsis xws luag.

Recarburizers tso cai rau cov neeg tsim khoom ua kom zoo - kho cov qib carbon kom zoo, tshwj xeeb tshaj yog tom qab oxidation poob thaum smelting.

Recarburizers yog indispensable nyob rau hauv ntau yam sectors:

Steelmaking kev lag luam

🏗️ Ntxiv rau hauv lub ladle lossis converter los kho cov qib carbon hauv carbon steel thiab alloy steels.

Kev lag luam Foundry

🔩 Txhim kho qhov zoo ntawm cov khoom cam khwb cia hlau, ua kom cov khoom siv zoo dua qub thiab ua kom tiav.

Hlau Hlau Production

🧱 Pab kom ua tiav qhov zoo tshaj plaws carbon sib npaug (CE), uas yog qhov tseem ceeb rau cov nodularity thiab graphite zoo.

Automotive & Heavy Machinery

🚗🛠️ Siv hauv kev tsim cov cav cav, lub zog, twj, thiab lwm yam hnav- cov khoom tiv thaiv.

✅ Txhim kho Carbon Yield Efficiency
✅ Txo cov nqi tsim khoom
✅ Txhim kho Metallurgical Quality
✅ Minimizes impurities (Low S, N, thiab tshauv)
✅ Txhawb nqa Uniform Carbon Distribution
✅ Fast Absorption nyob rau hauv Molten Hlau

Tus neeg siv khoom Profile & Kev sib tw pib:
Cov neeg tsim khoom ntawm high-purity aluminium rau aerospace thiab electronics industries tau tawm tsam ob qhov teeb meem: 1) Cov pa roj carbon ntau ntau (hydrogen) thiab tsis yog-hlau suav nrog hauv lawv cov khoom kawg, thiab 2) Qhov xav tau los txo qhov cuam tshuam ib puag ncig thiab tus nqi ntawm lawv cov txheej txheem kho dross.

Peb Cov Txheej Txheem & Kev Ua Haujlwm:
Peb tau nthuav qhia siab -purity Silicon Carbide ua ib qho tshiabfluxing thiab kho tus neeg sawv cevnyob rau hauv lawv tuav thiab kho qhov cub.

Khoom Spec:Peb muabMicronized High-Purity Silicon Carbide Powder (SiC >99%, d50=50 microns). Qhov loj particle loj yog qhov tseem ceeb rau kev tsim cov reactive, kua flux.

Txoj kev thov:SiC hmoov tau muab tov nrog lwm cov ntsev fluxes (piv txwv li, NaCl, KCl) los tsim ib tus tswvcomposite furnace tu thiab degassing flux. Qhov sib tov no tau txhaj los yog rabbled rau hauv lub molten aluminium da dej.

Mechanism:SiC hais ua raws li tsheej lab ntawm microscopic, ruaj khov substrates. Lawv nyiam thiab wetted oxide inclusions (Al2O3), yooj yim rau lawv agglomeration thiab tshem tawm mus rau hauv lub dross txheej. Nyob rau tib lub sijhawm, qhov sib xyaw flux tsim muaj kev tiv thaiv kev tiv thaiv, txo qis ntxiv hydrogen khaws los ntawm qhov cub cua sov.

Measurable Results & Tus nqi xa:

Khoom Zoo:Kev huv ntawm cov txhuas tau txhim kho zoo heev. Kev suav suav suav ( ntsuas los ntawm PoDFA lossis LiMCA) raug txo qis dua40%, thiab cov ntsiab lus hydrogen tau tas li khaws cia hauv qab 0.12 ml / 100g Al. Qhov no yog ib qho tseem ceeb heev rau kev ua kom tau raws li aerospace specification AS9100.

Kev txuag nyiaj ua haujlwm:Lub dross tsim nrog SiC-raws li flux yog drier, ntau mineralized, thiab muaj tsawg entrapped dawb hlau. Qhov no nce hlau rov qab thaum lub sij hawm dross recycling thiab txo qhov ntim ntawm ntsev ncuav mog qab zib xa mus pov tseg, txo tag nrho cov nqi kho mob los ntawm kev kwv yees.15%.

Txheej txheem tswj:Cov kev kho mob tau dhau los ua qhov xav tau ntau dua, txo qhov kev xav tau rov ua dua lub voj voog thiab cuam tshuam qhov kub thiab txias.
