Yuav ua li cas txiav txim siab cov qauv zoo ntawm silicon hlau
Rau cov neeg siv khoom, thaum yuav cov khoom siv silicon, lawv cia siab yuav cov khoom lag luam tsim nyog, thiab raws li silicon hlau cov tuam txhab, tsuas yog los xyuas kom meej cov khoom ua kom zoo ntawm cov khoom siv silicon, thiaj li yuav yeej cov xim ntawm cov neeg siv ntau dua, tau txais kev txhim kho zoo. Yog li no, txawm hais tias cov neeg siv khoom, lossis cov chaw tsim khoom lag luam, muaj kev txhawj xeeb txog qhov zoo ntawm silicon hlau. Yog li dab tsi yog tus qauv rau kev txiav txim siab zoo ntawm silicon hlau? Cov teeb meem no yuav piav qhia yooj yooj yim los ntawm coke hmoov tsim.
1. Sulphur hauv silicon hlau: Sulphur yog ib qho ua rau muaj kev phom sij hauv cov hlau sib tsoo, uas txo cov khoom ua kom zoo ntawm cov hlau hlau. Hauv cov hlau ua npua cov hlau cov hmoov ntses sulfur yog ntau dua 0.07% rau cov pov tseg. 11% ntawm cov leej faj coj mus rau hauv qhov cub tawg los ntawm tus foob pob tawg ua kom tau los ntawm cov ore. 3.5% los ntawm limestone; 82.5% los ntawm silicon hlau, yog li silicon hlau yog qhov tseem ceeb ntawm leej faj nyob rau hauv kev them nyiaj. Cov ntawv sulfur ntawm silicon hlau ncaj qha cuam tshuam rau kev lag luam ironmaking ntawm tshuab tawg. Thaum cov ntsiab lus leej faj ntawm silicon hlau ntau dua 1.6%, tus nqi ntawm silicon hlau nce ntxiv ntawm 1.8%, tus nqi ntawm limestone nce los ntawm 3.7%, thiab tus nqi ntawm ore nce 0.3%. Lub moj tej tawg ua rau txo qis li 1.5-2.0%. Metallurgical coke sulfur cov ntsiab lus tsis ntau dua li 1%, qhov loj thiab nruab nrab ntawm cov khoom siv tawg ua kom sov siv cov khoom siv xim hlau yog leej twg tsis yog 0.4-0.7%.
2, phosphorus hauv silicon hlau cov ntsiab lus: hlau metallurgical coke phosphorus cov ntsiab lus yuav tsum qis dua 0.02-0.03%.
3, tshauv cov ntsiab lus ntawm silicon hlau: cawv ntawm cov hmoov tshauv cov ntsiab lus ntawm silicon hlau ntawm lub tshuab tawg ua kom sov smelting yog qhov tseem ceeb heev. Thaum silica cov hmoov tshauv cov ntsiab lus nce ntxiv 1%, silica ntau npaum li 2-2.5%. Yog li ntawd, nws yog qhov yuav tsum tau los txo cov ntsiab lus silica tshauv.
4, cov lus tsis txaus ntseeg ntawm silicon hlau: raws li cov volatile cov ntsiab lus ntawm silicon hlau tuaj yeem txiav txim qhov kev loj hlob ntawm silicon hlau. Yog tias cov ntsiab lus tsis haum yog ntau dua 1.5%, nws txhais tau hais tias coke; Cov neeg tsis mloog lus yog tsawg dua 0.5-0.7%, uas dhau lawm, feem ntau paub tab metallurgical coke volatilization yog li 1%.
5, cov dej noo hauv silicon hlau: qhov ua kom ya raws qhov kev ntsuas yuav ua rau cov ntsuas hlau silicon tsis yog qhov tseeb, yog li ua rau cov cua sov hloov mus hloov. Tsis tas li ntawd, qhov nce ntawm silicon noo yuav ua kom M40 siab dua thiab M10 qis dua, uas yuav coj yuam kev rau lub nruas Performance index.
6, silicon hlau tshuaj ntsuam ua pawg rau: hauv qhov cub tawg smelting silicon hlau particle loj kuj tseem ceeb heev. Suav teb nyob rau yav dhau los qhov loj ntawm silicon hlau yuav tsum rau: rau loj coke cub (1300-2000 square metres) silicon hlau particle loj yog ntau dua 40 hli; Lub particle loj ntawm nruab nrab thiab me me siab silicon hlau ntau dua 25 hli. Lub particle loj ntawm silicon hlau yog 40-25 hli. Ntau tshaj li 80 hli ntawm silicon hlau rau tag nrho cov nplej, yog li nws txoj kev hloov ntau yam tsis loj. Nyob rau hauv txoj kev no, cov hlau silicon lumpiness yog cov teeb meem sib txawv, qhov sib txawv yog qhov loj, qhov tsis kam yog qhov me, thiab cov cua sov ua haujlwm zoo.
Cov no yog cov qauv ntsuas los ntsuas qhov ua tau zoo ntawm silicon hlau. Kuv vam tias koj tuaj yeem tuaj yeem qhia qhov tseeb sai thiab meej seb qhov zoo ntawm silicon hlau yog qhov tsim nyog lossis tsis dhau los ntawm cov no, thiaj li tiv thaiv lawv tus kheej txoj cai thiab kev nyiam. Yog tias koj tseem tsis paub qhov twg tsim cov khoom siv silicon hlau, yuav tsum tos txais hu rau peb lub tuam txhab, peb lub tuam txhab yuav ua raws li koj xav tau, muab koj nrog tsim nyog silicon hlau. Ntxiv rau, yog tias koj txaus siab nyob rau hauv silicon hlau, xav paub cov ntaub ntawv muaj feem xyuam ntxiv, lossis dab tsi tsis nkag siab, koj tuaj yeem tiv tauj peb lub tuam txhab, coke hmoov manufacturers rau koj cov lus teb ntxaws.
