Cov txheej txheem tsim khoom thiab ntws ntawm nkoj daim hlau feem ntau suav nrog cov kauj ruam tseem ceeb hauv qab no:

 

Raw khoom npaj theem

 

Hlau ore xaiv thiab ua

Hlau ore xaiv: Raws li qhov yuav tsum tau ua ntawm cov nkoj nkoj, ib qho chaw tsim nyog ntawm cov hlau ore raug xaiv. Piv txwv li, rau high-lub zog nkoj daim hlau, high-zoo hlau ore nrog high hlau cov ntsiab lus (feem ntau, cov hlau ore qib yuav tsum tau siab tshaj 60%) thiab cov ntsiab lus impurity tsawg (xws li sulfur, phosphorus thiab lwm yam impurities tsis zoo yuav tsum tau. nruj me ntsis tswj) feem ntau yog nyiam, xws li cov hlau ore los ntawm Vale hauv Brazil thiab BHP Billiton hauv Australia.

Crushing thiab tshuaj ntsuam: Cov khoom loj ntawm cov hlau ore mined yog crushed kom lawv cov particle loj raws li qhov yuav tsum tau ua tom ntej. Feem ntau, lub puab tsaig crushers, lub khob hliav qab crushers thiab lwm yam khoom siv yog siv los tsoo cov hlau ore rau hauv cov khoom me me, thiab tom qab ntawd cov khoom siv tshuaj ntsuam xyuas yog siv los tshuaj xyuas cov hlau ore uas ua tau raws li qhov xav tau ntawm qhov loj me (feem ntau ntawm 10 - 30mm).

Lwm yam raw khoom npaj

Coke thiab flux npaj: Raws li cov roj tseem ceeb thiab txo tus neeg sawv cev hauv cov txheej txheem hlau smelting, qhov zoo ntawm coke ncaj qha cuam tshuam rau kev ua haujlwm ntawm cov hlau smelting thiab qhov zoo ntawm cov hlau molten. Cov coke zoo nrog cov ntsiab lus siab ruaj ruaj (feem ntau siab dua 80% - 85%) thiab cov hmoov tshauv tsawg (feem ntau tsawg dua 15%) yog xav tau. Nyob rau tib lub sijhawm, fluxes xws li limestone thiab dolomite yuav tsum tau npaj. Cov fluxes no tuaj yeem txo qhov melting point ntawm hlau ore thiab txhim kho cov slagging thaum lub sij hawm hlau smelting txheej txheem. Qhov loj me me ntawm cov flux feem ntau yog tswj ntawm li 20 - 50mm.

 

Hlau smelting txheej txheem

 

Blast furnace hlau smelting

Charge thiab smelting: Cov npaj hlau ore, coke thiab flux yog loaded rau saum lub qhov cub tawg raws li ib qho kev faib ua feem (piv txwv li, feem ntau yog hais txog {{0}}.4 - 0.6 tons ntawm coke thiab 0.2 - 0.3 tons ntawm flux yuav tsum tau rau txhua tuj hlau ore). Nyob rau hauv lub qhov cub tawg, cov coke hlawv kom kub siab (qhov kub tuaj yeem ncav cuag 1500 - 1600 degree) thiab txo cov pa roj (feem ntau yog carbon monoxide), uas txo cov hlau oxide hauv cov hlau ore mus rau hauv cov hlau hlau. Cov txheej txheem no yog cov txheej txheem nruam smelting, thiab cov hlau ore maj mam yaj hauv qhov cub tawg thiab tsim cov hlau molten.

Molten hlau tapping thiab pretreatment: Tom qab ib lub sij hawm ntawm smelting, thaum ib tug npaum li cas ntawm cov hlau molten accumulates nyob rau hauv qab ntawm lub moj tej tawg rauv, lub molten hlau yog tawm los ntawm lub taphole. Cov hlau molten tshiab tshiab muaj qhov kub thiab txias (txog {{0}}} degree) thiab muaj qee qhov tsis huv (xws li sulfur, silicon, thiab lwm yam), yog li nws yuav tsum tau pretreated. Pretreatment txoj kev muaj xws li desulfurization, desiliconization, thiab lwm yam, kom txo tau cov impurity cov ntsiab lus nyob rau hauv cov hlau molten thiab txhim kho qhov zoo ntawm cov hlau molten. Piv txwv li, txoj kev txhaj tshuaj yog siv rau kev kho desulfurization, thiab cov tshuaj desulfurizing (xws li txiv qaub, magnesium hmoov, thiab lwm yam) yog txhaj rau hauv cov hlau molten kom txo cov sulfur cov ntsiab lus qis dua 0.02%.

Thaum lub sij hawm tus txheej txheem ntawm hlau ore crushing thiab tshuaj ntsuam, cov khoom nram qab no mas siv:

 

Cov khoom siv crushing

 

Puab tsaig crusher

Txoj cai ua haujlwm: Nws feem ntau crushes ore los ntawm lub sij hawm txav ntawm lub puab tsaig txav thiab lub puab tsaig ruaj khov. Lub phaj lub puab tsaig txav tau ua rau ib ntus rov ua haujlwm nyob ib puag ncig ntawm lub tog raj kheej ntawm lub puab tsaig ruaj khov, txav mus rau thiab tawm mus ua ke. Thaum lub puab tsaig phaj txav mus ze rau lub puab tsaig ruaj ruaj, cov ore yog crushed los ntawm compression, splitting thiab khoov ntawm ob lub puab tsaig phaj; Thaum lub puab tsaig txav tau tawm ntawm lub puab tsaig ruaj khov, cov pob zeb crushed tau tawm ntawm lub crushing chamber nyob rau hauv qhov kev txiav txim ntawm lub ntiajteb txawj nqus.

Cov yam ntxwv ntawm kev siv: Lub puab tsaig crusher muaj cov qauv yooj yim thiab ruaj khov thiab tuaj yeem tsoo cov pob zeb ntawm ntau yam hardnesses. Nws yog qhov tshwj xeeb tshaj yog tsim nyog rau kev sib tsoo ua ntej ntawm cov hlau loj loj, thiab tuaj yeem tsoo cov hlau ore loj rau qhov me me ntawm li 100 - 300mm, npaj rau cov txheej txheem crushing tom ntej.

Lub khob hliav qab crusher

Txoj cai ua haujlwm: Qhov chaw ua haujlwm ntawm lub khob hliav qab crusher yog lub khob hliav qab thiab lub khob sab nraud. Lub khob hliav qab yog tsau, thiab lub khob hliav qab sab hauv ua rau eccentric rotary motion. Cov hlau ore yog crushed los ntawm compression thiab sib tsoo ntawm ob lub khob hliav qab. Thaum lub sij hawm crushing txheej txheem, cov hlau ore nkag mus rau hauv lub crusher los ntawm sab saum toj noj inlet. Raws li lub khob hliav qab rotates, cov ore yog tsis tu ncua compressed thiab hauv av nyob rau hauv lub crushing chamber kom txog rau thaum lub particle loj raws li qhov yuav tsum tau thiab yog tawm los ntawm lub hauv qab.

Cov yam ntxwv ntawm kev siv: Lub khob hliav qab crusher yog tsim rau nruab nrab thiab zoo crushing ua haujlwm. Nws tuaj yeem tsoo cov hlau ore uas tau ua ntej crushed los ntawm lub puab tsaig crusher rau hauv cov khoom uas muaj ntau yam sib xws thiab cov khoom me me. Feem ntau, cov hlau ore tuaj yeem raug crushed mus rau qhov loj me ntawm 10 - 30mm, uas yog tsim rau cov txheej txheem tsim khoom nrog cov kev xav tau siab rau cov khoom me me.
