Txheej txheem cej luam ntawm Pure Iron Powder
Cov hmoov hlau ntshiab, tseem hu ua cov hmoov hlau ncaj, yog ib hom hmoov hlau tseem ceeb uas siv dav hauv ntau yam lag luam. Nws purity thiab nplua particle loj ua rau nws haum rau ntau daim ntawv thov, xws li kev tsim khoom mus rau tshuaj catalysis.
Daim ntawv thov ntawm Pure Iron Powder
Manufacturing Mechanical Parts: Cov hmoov hlau ntshiab yog cov khoom siv tseem ceeb hauv cov hmoov metallurgy, suav txog kwv yees li 80% ntawm tag nrho cov hmoov hlau noj. Nws yog siv los tsim cov khoom siv kho tshuab nrog siab precision thiab lub zog.
Vuam Electrodes: Ntxiv 10 ~ 70% ntshiab hlau hmoov rau vuam electrode txheej tuaj yeem txhim kho cov txheej txheem vuam thiab txhim kho kev ua haujlwm zoo.
Txiav cov khoom siv hlau: Thaum txiav hlau, txhaj cov hmoov hlau rau hauv cov pa oxygen-acetylene nplaim tuaj yeem txhim kho kev ua tau zoo, nthuav dav ntau yam ntawm cuttable steel hom, thiab nce qhov siab tshaj plaws cuttable thickness.
Tshuaj Catalyst: Pure hlau hmoov kuj yog siv los ua ib qho catalyst nyob rau hauv cov tshuaj tiv thaiv, xws li rau noble hlau txo, alloy ntxiv, thiab tooj liab hloov.
Lwm Daim Ntawv Thov: Dhau li ntawm kev siv hauv kev lag luam, cov hmoov hlau ntshiab kuj tuaj yeem siv los ua tus neeg sawv cev txo qis thiab cov khoom khaws cia kom tsis txhob muaj roj thiab rog los ntawm kev lwj.
Kev faib cov hmoov hlau
Hlau hmoov feem ntau muab faib ua tsib qib: hmoov coarse, hmoov nruab nrab, hmoov zoo, hmoov ultrafine, thiab micro-zoo hmoov. Qhov luaj li cas ntawm particle rau txhua qib yog raws li nram no:
Coarse Hmoov: Cov khoom sib txawv ntawm 150 ~ 500 micrometers.
Cov hmoov nruab nrab: Cov khoom sib txawv ntawm 44 ~ 150 micrometers.
Hmoov zoo: Cov khoom sib txawv ntawm 10 ~ 44 micrometers.
Ultrafine hmoov: Particles xws li 0.5 ~ 10 micrometers.
Micro-Fine hmoov: Cov khoom me dua 0.5 micrometers.
Cov txheej txheem ntau lawm ntawm Hlau Hmoov
Muaj ntau txoj hauv kev uas feem ntau siv los tsim cov hmoov hlau ntshiab, suav nrog:
Txheej txheem Höganas: Koom nrog txo cov hlau ore nplua nrog cov hmoov nplej qis coke breeze-limestone sib xyaw hauv SiC txo lub nkoj kom sov txog li 1200 degree. Cov hlau ua npuas dej tau raug crushed thiab txo qis ntxiv rau hauv lub tshuab hluav taws xob ntawm 800 ~ 900 degree.
Pyron txheej txheem: Koom nrog oxidizing low-carbon steel nplai rau Fe2O3 thiab tom qab ntawd txo nws nrog hydrogen nyob rau hauv qhov cub siv kub ntawm qhov kub tsis tshaj 1050 degree.
Dej Atomization txheej txheem: Koom nrog melting low-carbon scrap steel, tshem tawm impurities, thiab atomizing cov hlau molten rau hauv cov tee dej los ntawm cov dej siab. Cov tee dej txias thiab khov rau hauv cov hmoov, uas tom qab ntawd txo qis hauv qhov cub siv.
QMP txheej txheem: Tsim los ntawm Quebec Metal Powder, cov txheej txheem no koom nrog atomizing high-purity molten npua hlau rau hauv cov khoom, ib nrab oxidizing lawv, thiab tom qab ntawd txo thiab annealing lawv nyob rau hauv qhov cub siv.
Tshwj xeeb hom hlau hmoov
Carbonyl Hlau Hmoov: Ua los ntawm reacting hlau nrog carbon monoxide nyob rau hauv qhov kub thiab txias. Nws muaj qhov sib nqus permeability siab ntawm cov frequencies thiab yog siv dav hauv cov khoom sib nqus.
Hauv cov ntsiab lus, cov hmoov hlau ntshiab ua lub luag haujlwm tseem ceeb hauv ntau qhov kev lag luam vim nws cov khoom tshwj xeeb thiab ntau yam. Nkag siab txog nws cov ntawv thov, kev faib tawm, thiab cov txheej txheem tsim khoom yog qhov tseem ceeb rau kev siv tau zoo thiab kev txhim kho ntxiv.
