Brown Corundum Micropowder Manufacturing Process uye Kudzora Kwemhando
Famba mufekitari ipi neipi yekugadzira hardware, uye mhepo inozadzwa nekunhuhwirira kwakasiyana kweguruva resimbi, kunoperekedzwa nekutinhira kwemashini ekukuya. Maoko evashandi anozorwa girizi nhema, asi hupfu hwakashava hunopenya pamberi pavo—brown corundum micropowder-ndiyo "mazino" anokosha uye "kupinza" kweindasitiri yemazuva ano. Ichi chinhu chakaoma, chinowanzozivikanwa se "corundum" nevanopinda mukati meindastiri, inoshandura shanduko kubva kune ore kuenda kuhupfu hwakatsetseka, bvunzo yekupisa kwepamusoro uye kurongeka.
1. Chiuru-madhigirii Marimi: Iyo Kugadzira Maitiro eBrown Corundum Micropowder
Brown corundum micropowderinotanga semapundu asingashamisi e bauxite. Usarerutsa mapundu evhu aya; anofanirwa kunge ari epamusoro-giredhi ores ane Al₂O₃ yemukati inokwana 85% kuti akwanise kunyungudutswa. Pakavhurwa choto chekunyunguditsa, chinhu chinonakidza kuona-tembiricha iri mukati mechoto yemagetsi inokwira, inosvika 2250°C. Bauxite, yakasanganiswa nesimbi filings uye coke, inodonha uye inonyunguduka mumoto wakanyanya, kuchenesa nekubvisa tsvina, pakupedzisira ichigadzira dense brown corundum blocks. Sarudzo yerudzi rwechoto inobatawo pachayo: choto chinorerekera chinopa yakanakisa fluidity uye yakakwirira kuchena, yakakodzera zvigadzirwa zvakanaka; choto chakagadzika chinopa kuburitsa kwakakwira uye mutengo wakaderera. Vagadziri vanowanzo sarudza zvichienderana nezvinodiwa.
Brown corundummabhuroko matsva kubva muchoto achiri "makororo," kure nekuve hupfu hwakatsetseka. Tevere, chinopwanya chinotora nzvimbo: chimeno chine mazino maviri-mano ekupwanya-pwanya, kupatsanura huwandu, ukuwo vertical impact crusher ichiita kupwanya kwakanaka, ichityora zvimedu kuita zvidimbu zvemillimeter. Asi handizvo zvese-kuparadzaniswa kwemagineti uye kubviswa kwesimbi kwakakosha pamhando. Kana yakabatidzwa, yakakwira-gradient magineti separator inogona kubvisa zvachose chero yasara mafirita esimbi kubva pane izvo. High-simba magineti separators anoshandiswa nemakambani akaita seHenan Ruishi anogona kuderedza Fe₂O₃ kusvika pazasi 0.15%, achiisa hwaro hwekuzotora kunotevera.
Iyo pickling tank inewo zvakavanzika. A 15% -25% hydrochloric acid solution inoshandiswa kwemaawa 2-4. Yakasanganiswa neZhenyu Grinding's patented "push-pull cleaning device," poda inozununguswa nekugezwa, ichinyungudutsa tsvina yakaita sesilicon necalcium, ichiwedzera kuchena kwehupfu hwakatsetseka. Yekupedzisira yekutarisa nhanho yakafanana ne "dhizaini": vibrating skrini inopa inoenderera yekutarisa, kupatsanura iwo akatsetseka zvimedu kubva kune akakora kusvika kune akatsetseka. Chongqing Saite Corundum's patented screening kifaa inotobatanidza matatu akaturikidzana ezviratidziro pamwe nehafu-chikamu chidzitiro, kuve nechokwadi chekugovera saizi yechikamu sezvakaita sekunge kuyerwa nerura. Iyo sieved poda yakatsetseka inobva yanyorwa sezvinodiwa-200 # -0 uye 325 #-0 zvinowanzoitika. Chimedu chimwe nechimwe chakafanana sejecha, budiriro yechokwadi.
2. Kuongorora Kwakanaka: The Lifeline yeMicropowder Quality
Inoshandiswa kupi brown corundum micropowder? Kubva pakukwenenzvera girazi renhare mbozha kusvika pakumisikidza simbi mill blast furnaces, kunyangwe kuderera kwekuita kudiki kunogona kukonzera kutsamwa kwevatengi. Nokudaro, kutonga kwehutano kunogara kuchikonzera kusagadzikana mufekitari. Kutanga, funga nezvekugadzirwa kwemakemikari-Al₂O₃ zvinyorwa zvinofanira kuva ≥95% (zvigadzirwa zvepamusoro zvinoda ≥97%), TiO₂ ≤3.5%, uye SiO₂ uye Fe₂O₃ inofanira kuchengetwa mukati me1% uye 0.2% maererano. Nyanzvi dzerabhoritari dzinotarisa spectrometer zuva nezuva; kunyangwe kudiki kudiki kudiki kwe data kunogona kutungamira mukugadziriswa kweiyo batch yese.
Kuongororwa kwemidziyo yemuviri kwakaoma zvakaenzana:
Iyo Mohs kuoma kunofanirwa kusvika 9.0. Sample inokweshwa ichipesana nereference plate; chiratidzo chipi nechipi chokupfava chinorangarirwa sokukundikana.
Chokwadi density inogumira ku3.85-3.9 g/cm³. Kutsauka kunoratidza dambudziko nekristaro chimiro.
Refractory test inotonyanya kuda-kutsemuka nehupfu mushure mekukandwa muchoto che1900 ° C kwemaawa maviri? Batch rese rakaraswa!
Particle saizi kufanana kwakakosha pakupukuta mhedzisiro. Muongorori wemhando anoparadzira chipunu chehupfu pasi pe laser particle size analyzer. Chero kukanganisa muD50 kukosha kunodarika 1% kunoonekwa sekukundikana. Mushure mezvose, saizi isina kuenzana inokonzeresa kukwenya kana zvigamba pane yakakwenenzverwa simbi, zvichitungamira kune zvichemo kubva kune vatengi.
Iyo yenyika standard GB/T 2478-2022, yakagadziridzwa muna 2022, yave indasitiri ironclad. Iri gwaro gobvu retekinoroji rinotonga zvese kubva kumakemikari ekuumbwa uye chimiro chekristaro kusvika pakurongedzerwa nekuchengetwa kwebrown corundum. Semuenzaniso, zvinoda kuti α-Al₂O₃ iratidze yakajairwa trigonal crystal fomu. Unoona heterogeneous crystallization pasi pe microscope? Ndine urombo, chigadzirwa chichavharirwa! Vagadziri izvozvi vanotofanirwa kunyoresa tembiricha yekuchengetera uye humidity mazinga-nekutyira kuti mamicropowder achanyorova uye akabatana pamwe chete, zvichikuvadza mukurumbira wavo.
3. Kusandura Marara kuita Pfuma: Kudzokorodza Tekinoroji Inoputsa Dambudziko Resource
Indasitiri yecorundum yakagara ichitambura nekuunganidzwa kwemarara abrasives uye mavhiri ekukuya, izvo zvisingatore nzvimbo chete asiwo zvinosvibisa zvakatipoteredza. Nekudaro, mumakore maviri apfuura, tekinoroji ye "recycled corundum" yakabuda, ichipa zvinhu zvinorasa hupenyu hutsva. Patent nyowani muYingkou, Liaoning Province, yatora kudzokorora danho rinowedzera: kutanga, tsvina corundum zvigadzirwa zvinopihwa "kugeza" kubvisa zvinosvibisa, zvichiteverwa nekupwanya uye kuparadzaniswa kwemagineti, uye pakupedzisira, yakadzika pickling ine hydrochloric acid. Kuita uku kunowedzera kubviswa kwetsvina ne40%, zvichiunza kushanda kwezvinhu zvakadzokororwa pedyo neiyo yemhandara micropowder.
Iko kushandiswa kwezvinhu zvakagadziriswa zvakare kuri kuwedzera. Refractory mafekitori anoda kuishandisa kune taphole ivhu-inofanirwa kusanganiswa mune zvinokandwa zvakadaro, uye zvinhu zvakadzokororwa zvinopa zvinoshamisa mutengo-kubudirira. Kunyange zviri nani, nzira yekudzokorora inoderedzabrown corunduminodhura ne15% -20%, zvichiita kuti maboss afare zvisingaite. Zvisinei, nyanzvi munyaya dzemaindasitiri dzinonyevera kuti: “Kukwenenzvera chaiko kunoda zvinhu zvisina kuchena zvegiredhi rekutanga.
4. Mhedziso: Micropowder, Diki Sezviri, Inotakura Huremu hweIndasitiri
Kubva pamoto unopfuta wemagetsi arc furnaces kusvika kuhum yemagnetic separators, kubva pakunyunguduka kwematangi ekunhonga kusvika kumitsetse yelaser particle size analyzers-kuzvarwa kwebrown corundum micropowder idiki diki diki indasitiri yemazuva ano. Mapatent matsva, miitiro mitsva yenyika, uye tekinoroji yakadzokororwa zvinoramba zvichisimudzira sirin'i yeindasitiri kumusoro. Kunodzika kwemaindasitiri 'kudiwa kwepedyo-yakanyanya-kunyanya kurapwa kwepamusoro kunoenderera mberi nekutyaira micropowder mhando yakakwira. Pamutsetse wegungano, masaga ehupfu yebrown anonamwa oiswa mumarori, achienda kumafekitari munyika yose. Vanogona kunge vasina kuimbwa, asi vanosimbisa simba repakati reMade in China, pasi pepamusoro peporishi yaro.
