Kev ua lag luam tus nqi hloov pauv li cas rau ferrosilicon qib 72 thiab 75 txawv?

Yog tias koj niaj hnub sib piv cov khoom xa tawm rau FeSi 72 thiab FeSi 75, koj yuav pom tias ob lub npe feem ntau mus rau tib qho kev taw qhia, tab sis tsis nyob rau tib lub sijhawm, thiab tus nqi sib txawv ntawm lawv yog nthuav tawm lossis cog lus. Rau tus neeg yuav khoom, qhov no tsis yog qhov kev xav - nws yog ib lo lus nug ntawm thaum twg los kho qhov ntim, yuav ua li cas ntsuas qhov kev pheej hmoo thiab vim li cas "pheej yig dua ib tuj" qee zaum hloov mus rau kim dua hauv kev muaj tiag. Hauv qab no - yog lub tswv yim logic ntawm vim li cas lub lag luam rau ferrosilicon 72 thiab 75 coj txawv txawv - txawv.

Nqe Lus Nug 1: Dab tsi feem ntau txiav txim siab tus nqi ntawm ferrosilicon 72 thiab 75?
Teb 1:FeSi 72 thiab FeSi 75 feem ntau muaj ntau qhov chaw ntawm tus nqi txav:
- tus nqi hluav taws xob thiab kev ua haujlwm ntawm lub tshuab hluav taws xob;
- tus nqi txo cov neeg sawv cev thiab cov khoom siv;
- kev txwv ntawm cov khoom siv vim yog -rau kev kho, tshuaj xyuas thiab kev siv peev txheej;
- logistics: freight, ntim, chaw nres nkoj, xa khoom hauv tsev;
- rhiab heev ntawm kev thov los ntawm steelmaking thiab foundry tuam txhab (replenishment ntawm cov khoom muag, raws caij nyoog, kev yuav khoom nyob rau hauv "yoj");
- Cov txiaj ntsig thiab cov nqe lus them nqi cuam tshuam rau tus nqi xa tawm thiab tus nqi xa khoom zaum kawg.

Thaum cov xwm txheej no hloov pauv, ob lub npe zoo li hnov ​​​​mob. Qhov sib txawv pib qhov twg kev lag luam ntsuas tsis yog tsuas yog "feem pua ​​ntawm Si", tab sis muaj cov khoom zoo thiab muaj peev xwm hloov pauv.

Nqe Lus Nug 2: Vim li cas FeSi 75 tuaj yeem nce nqi sai dua FeSi 72?
Teb 2:FeSi 75 feem ntau yuav khoom rau cov kev xav tau ntau dua, qhov twg qhov koob tshuaj raug thiab ruaj khov ntawm qhov tshwm sim yog qhov tseem ceeb. Yog li ntawd, thaum lub sij hawm ntawm kev thov hnyav, kev ua lag luam "them saum toj" tsis yog rau siab dua Si, tab sis rau kev sib xyaw ua ke ntawm yam:
- batch-rau-batch ruaj khov batch;
- kev txwv meej ntawm impurities raws li tus neeg yuav khoom xav tau;
- tswj cov feem thiab cov nqi qis qis;
- poob tsawg kawg thaum tuav thiab thauj.

Yog tias muaj qee qhov "tsim" ntau, tus nqi them rau FeSi 75 loj hlob sai dua tus nqi ntawm FeSi 72 hloov.

Nqe Lus Nug 3: Thaum twg tuaj yeem FeSi 72 txav nrawm dua FeSi 75?
Teb 3:FeSi 72 feem ntau yog qhov "ntau" ntau dua. Thaum lub lag luam nkag mus rau qhov kev nthuav dav ntxiv, 72 tus nqi yuav hnov ​​​​mob sai dua vim tias nws muaj kev lag luam ntau dua thiab cov neeg yuav khoom hloov pauv sai dua. FeSi 75 qee zaum zoo li calmer thaum lub sijhawm zoo li no yog tias qhov ntim tau ruaj ntseg hauv kev sib raug zoo mus ntev thiab cov neeg yuav khoom tsis nyiam "nrhiav" nrog kev ua lag luam ntawm cov khoom lag luam.

Nqe Lus Nug 4: -Vim li cas tus nqi sib txawv ntawm FeSi 72 thiab FeSi 75 hloov?
Teb 4:Feem ntau muaj peb lub tshuab ua haujlwm.

• Kev hloov pauv hauv koj cov txheej txheem.

  Yog tias koj lub vev xaib tuaj yeem hloov pauv FeSi 75 nrog FeSi 72 (tom qab rov xam cov nqi nkag thiab tshuaj xyuas cov dilution), tus nqi sib txawv feem ntau compressed: cov neeg yuav khoom nres "them nyiaj ntau dhau ntawm tus nqi." Yog tias kev hloov pauv muaj kev pheej hmoo (qhov rais me me, kev siv tshuaj ntau ntau), tus nqi sib txawv widens.

• Kev pheej hmoo ntawm kev poob los ntawm - rau cov feem ntau thiab cov trifles.

  Thaum txoj kev ntev, cov overloads hnyav, thiab cov ntim tsis muaj zog, qhov sib faib ntawm cov nplua nyiaj nce, cov khoom ua plua plav, - oxidizes sai dua thiab "zoo Si input" txo. Thaum lub sijhawm zoo li no, cov neeg yuav khoom txaus siab them ntau dua rau cov khoom siv uas tswj cov feem ntau thiab tsim cov txiaj ntsig zoo ib yam, thiab qhov no feem ntau txhawb nqa tus nqi siab dua rau FeSi 75.

• rhiab heev rau impurities thiab ua raws.

  Yog tias cov neeg yuav khoom tau nce kev tswj hwm ntawm impurities lossis kev ruaj ntseg ntawm qhov tshwm sim (piv txwv li, vim yog - cov kev xav tau zoo), tus nqi rau cov khoom "ruaj khov" nce sai dua. Thiab tom qab ntawd qhov tseem ceeb tshaj yog tsis yog daim ntawv lo 72 lossis 75, tab sis lub peev xwm ntawm tus neeg muag khoom ua kom cov kev xav tau ruaj khov.

Nqe Lus Nug 5: Yuav ua li cas los sib piv cov lus pom zoo rau FeSi 72 thiab FeSi 75?
Teb 5:Sib piv tsis yog tus nqi ib tuj xwb, tab sis tus nqi ntawm "kev siv tswv yim zoo Si". Hauv kev xyaum, "kev ua tau zoo" feem ntau ua tsis zoo los ntawm:
- feem ntau ntawm kev nplua (poob xws li plua plav, poob vim oxidation);
- dav variation nyob rau hauv loj (lig dissolution thiab unstable sawv ntawm Si);
- instability ntawm batch (tus neeg teb xov tooj raug yuam kom them, noj nce).

Raws li qhov tshwm sim, "pheej yig" FeSi 72 tuaj yeem dhau los ua tus nqi kim dua ntawm cov nqi zaum kawg tshaj qhov ruaj khov FeSi 75.

Nqe Lus Nug 6: Kuv tuaj yeem txo qhov cuam tshuam ntawm tus nqi luv luv li cas?
Teb 6:Kev yuav khoom feem ntau yog los ntawm ob peb kauj ruam:
- faib lub ntim rau hauv ob feem (kaw qhov xav tau tam sim no thiab tawm ib feem rau tom qab), tsis yog ib tus nqi "tag nrho ib zaug";
- kho qhov feem thiab txwv rau cov khoom me me hauv kev yuav khoom, kom tsis txhob them tus nqi lag luam thiab tib lub sijhawm tsis tau txais cov khoom tsis ruaj khov;
- thov ntau daim ntawv pov thawj ntawm kev tshuaj xyuas rau cov khoom sib txawv txhawm rau pom kev sib kis, thiab tsis yog ib daim ntawv "zoo tagnrho";
- Yog tias koj cov txheej txheem tiag tiag xav tau FeSi 75 rau kev txhaj tshuaj kom raug, kho nws raws li cov tswv yim tseem ceeb thiab tsis txhob siv koj lub tswv yim ntawm kev yuav khoom ib zaug ib leeg.

Nqe Lus Nug: Puas yog FeSi 75 ib txwm kim dua FeSi 72?
Teb: Feem ntau yog, tab sis tus nqi sib txawv - nyob ntawm qhov tsis txaus ntawm cov khoom ruaj khov thiab muaj peev xwm hloov pauv hauv ib qho kev siv tshuab.

Lus Nug: Vim li cas tus nqi sib txawv qee zaum nce siab?
Teb: Thaum "zoo" batch nrog cov qib tswj thiab cov khoom siv tsis zoo tau dhau los ua tsawg, cov neeg yuav khoom sib tw ntawm qhov tsim nyog es tsis yog feem pua ​​​​ntawm Si.

Lus Nug: Puas muaj peev xwm hloov ntawm FeSi 75 mus rau FeSi 72 yog tias tus nqi nce?
Teb: Qee lub sij hawm nws muaj peev xwm, tab sis nws muaj kev nyab xeeb dua rau thawj zaug rov xam tus nqi nkag thiab lees paub qhov tshwm sim nrog kev sim batch kom tsis txhob poob kev tswj hwm ntawm cov txheej txheem.

Nqe Lus Nug: Dab tsi yog qhov kev siv nyiaj zais ntau tshaj plaws thaum lub sijhawm txav mus los?
Teb: Ua kom nplua nuj thiab tsis ruaj khov ntawm cov khoom siv: lawv txo cov tswv yim zoo ntawm Si thiab nce qhov kev siv tiag tiag.

- Peb pab cov neeg yuav khoom tsim cov kev qhia tshwj xeeb "kom haum rau qhov tshwm sim": feem, kev txwv ntawm kev nplua, lub hauv paus meej rau kev tswj hwm thiab kev lees txais.
- Peb muab qhov tseem ceeb ntawm kev khaws cia cov feem hauv kev thauj mus los: ntim thiab thauj khoom tau teeb tsa hauv txoj hauv kev los txo qhov kev puas tsuaj thiab kev loj hlob ntawm kev nplua ntawm txoj kev ntev.
- Peb qhia kev ruaj ntseg los ntawm batch: raws li kev thov, peb npaj cov ntaub ntawv rau ntau pawg sib txawv txhawm rau ntsuas qhov sib kis, thiab tsis yog ib qho "daim duab".
- Peb pab nrog cov laj thawj ntawm kev xaiv 72 lossis 75 rau koj txoj haujlwm, kom qhov kev txiav txim siab raws li tus nqi kawg, thiab tsis yog ntawm tus nqi ib tuj xwb.

Peb ua haujlwm ua lub Hoobkas xa tawm nrog kev xa khoom ncaj qha thiab muaj peev xwm txhua hli. Ntau lawm puag - txog 30 000 m². Peb cov khoom siv dav dav 100+ lub teb chaws thiab cheeb tsam, thiab peb cov neeg siv khoom ntau dua 5 000 tuam txhab. Pab pawg muag khoom taw qhia kev lag luam thiab pab tswj cov kev qhia tshwj xeeb thiab cov ntaub ntawv kom kev yuav khoom mus zoo: los ntawm kev tshuaj xyuas tuaj mus rau kev siv ruaj khov hauv kev cob qhia. Ntxiv rau ferrosilicon, peb muab metallurgical silicon thiab lwm yam khoom siv hlau.
