Case ntawm Guilin Hongcheng txiv qaub ntsug sib tsoo zeb
Txiv qaub yog ib hom roj inorganic cementing khoom nrog calcium oxide ua lub ntsiab tivthaiv, uas plays lub luag haujlwm tseem ceeb hauv cov txheej txheem steel hlau.Lub luag hauj lwm ntawm txiv qaub hmoov nyob rau hauv cov txheej txheem ntawm steelmaking yog dab tsi?Dab tsi zeb yog siv rau steelmaking txiv qaub hmoov ua?Guilin Hongcheng txiv qaub sib tsoo khoom Hoobkasqhia txog kev siv tshuab ntawm txiv qaub hmoov rau steelmaking.
1.Dab tsi cuam tshuam steel zeb siv cov txiv qaub hmoov kom muaj?
(1) Kev tshem tawm cov sulfur, phosphorus, silicon, arsenic thiab lwm yam teeb meem: vim hais tias cov oxides ntawm cov teeb meem no feem ntau yog ib co acidic tshuaj, yog li nws yog ib txoj hauv kev zoo los muab lawv nrog qee cov tshuaj alkaline los tsim cov tebchaw ruaj khov. .Txawm li cas los xij, thaiv cov calcium oxide, nrog nws cov khoom siv nplua nuj ntawm cov khoom siv raw thiab tus nqi tsim nyog, tuaj yeem tsim cov sib txawv ntawm cov oxides ntawm S, P, Si thiab As, thiab dhau los ua qhov kev xaiv zoo tshaj plaws rau kev tshem tawm ntawm S, P, Si thiab As.
(2) Decarbonization: cov txiaj ntsig ntawm niaj hnub metallurgy qhia tias hlau decarbonization feem ntau yog indirect oxidation, oxygen thawj oxidation ntawm hlau, nruab nrab ntawm hlau oxide nyob rau hauv oxidation ntawm hlau carbon, thiab lub hauv paus ntawm slag CaO / SiO ₂ rau slag hlau. oxide rau cov tshuaj tiv thaiv cuam tshuam kev tsiv teb tsaws diffusion muaj qhov cuam tshuam tseem ceeb, nce CaO hauv slag, yog qhov tsim nyog rau hlau decarbonization.
(3) Cov kab hluav taws xob tiv thaiv: cov khoom siv acidic Fe ₂ O ₃ nyob rau hauv qhov seem thiab SiO ₂ tuaj yeem yooj yim cuam tshuam nrog cov tshuaj alkaline MgO hauv cov khoom siv hauv cov khoom siv hluav taws xob kom ua rau lub qhov cub tawg.Ntxiv calcium oxide, cov tshuaj acidic no nyiam tshaj tawm nrog calcium oxide.Yog li ntawd, pib los ntawm kev tiv thaiv rauv hauv ob sab phlu, calcium oxide yog siv los ua cov khoom siv slag, uas tuaj yeem ua rau qeeb qeeb ntawm qhov tawg ntawm qhov cub hauv ob sab phlu.
(4) Txo cov hlau txaws: cov tshuaj acidic hauv cov slag Fe ₂ O ₃ thiab SiO ₂ tuaj yeem yooj yim cuam tshuam nrog cov tshuaj alkaline MgO hauv cov khoom siv hauv cov khoom siv hluav taws xob kom ua rau lub qhov cub tawg.Ntxiv calcium oxide, cov tshuaj acidic no nyiam tshaj tawm nrog calcium oxide.Yog li ntawd, pib los ntawm kev tiv thaiv rauv hauv ob sab phlu, calcium oxide yog siv los ua slag, uas tuaj yeem ua rau txo qis tus nqi yaig ntawm lub qhov cub hauv ob sab phlu.Ntxiv cov txiv qaub hmoov rau hauv cov hlau molten lossis dej hlau yog siv los ua cov slag ua tus neeg sawv cev hauv cov txheej txheem steelmaking lossis hlau ua, thiab cov khoom tsis zoo xws li sulfur lossis phosphorus hauv cov hlau molten lossis hlau dej kuj tuaj yeem raug tshem tawm hauv cov txheej txheem no.
2.Dab tsi zeb siv rau steelmaking txiv qaub hmoov ua?
Lub fineness ntawm txiv qaub hmoov siv nyob rau hauv steel mills feem ntau yog hais txog 120 mesh, thiab tus nqi ntawm cov txiv qaub hmoov siv rau steelmaking yog loj, yog li ntawd lub peev xwm ntawm cov khoom yog siab.Kev sib tsoo ntawm Guilin Hongcheng ntsug zeb muaj cov hauv qab no zoo:
Technical parameters ntawm Guilin Hongcheng ntsug sib tsoo zeb
(1) Cov txheej txheem yooj yim ntws, cov cuab yeej siv tsawg dua, nyob thaj tsam me me;
(2) Kev tiv thaiv ib puag ncig, tag nrho cov txheej txheem txheej txheem raug kaw tag nrho, kev ua haujlwm tsis zoo, tsis txhob khiav plua plav, plua plav tawm mus txog lub teb chaws emission tus qauv qis dua 30 mg / m3, cov txheej txheem du, lub suab nrov qis;
(3) Cov khoom siv hluav taws xob poob qis me me, cov khoom tsis zoo tuaj yeem ua haujlwm rau ntau tshaj 2 xyoos;
(4) Tag nrho cov txheej txheem yog tsim los ntawm cov kws tshaj lij kev lag luam, qib ntau lawm kuj yog siab heev, yog li cov txheej txheem kev ua haujlwm tau zoo siab, tuaj yeem khiav 24 teev tsis cuam tshuam, cov cuab yeej ua haujlwm tuaj yeem ncav cuag ntau dua 95%;
(5) Kev txuag hluav taws xob thiab hluav taws xob txuag, piv nrog lwm cov khoom siv tuaj yeem txuag tau ntau dua 50% ntawm hluav taws xob.
(6) Kev sib tsoo zoo: cov txheej txheem muaj peev xwm loj (cov khoom siv loj loj tuaj yeem ncav cuag ntau tshaj 100 tons), kev ua haujlwm siab, cov khoom tuaj yeem ua tau raws li qhov xav tau tiag tiag;
(7)Compared with other equipment at home and abroad, the whole system is simple, convenient operation and maintenance, the professional requirements for operators are not high, generally suitable for the preparation of lime powder in various types of domestic enterprises, and can save labor costs; Less equipment loss, less iron pollution, the color of the grinding product will not change, the whole process is closed negative pressure operation, do not discharge dust, and will not bring in pollutants.Consulting the price of Guilin Hongcheng lime vertical grinder, welcome to contact email: mkt@hcmilling.com
