Taw qhia
Thaum cov neeg yuav khoom yuav ferrosilicon (FeSi), "zoo" feem ntau txhais tau tias ntau dua li tsuas yog ntaus ib feem pua ntawm silicon ntawm daim ntawv. Nyob rau hauv niaj hnub steelmaking thiab foundry siv, zoo yog hais txogsib xws, purity (kev tswj tsis pub dhau), thiab seb cov khoom coj li cas hauv kev yaj thiab rov qab los. Yog tias koj tab tom xa FeSi lossis hloov cov chaw muag khoom, nws yog ib qho kev txhawj xeeb txog "Peb yuav ua li cas kom paub tseeb tias cov khoom yog huv thiab ruaj khov?" Hauv qab no yog txoj hauv kev uas cov neeg yuav khoom thiab cov neeg tsim khoom feem ntau tswj hwm qhov zoo thiab purity.
Khoom Description
Q1: Qhov "zoo thiab purity" txhais li cas rau ferrosilicon hauv kev lag luam tiag?
Hauv kev lag luam feem ntau, qhov zoo thiab purity feem ntau muaj peb yam:
Cov ntsiab lus silicon ruaj khov(piv txwv li, FeSi75 nyob rau hauv ib qho kev txhim khu kev qha xws li 74–76%)
Tswj impuritiesxws liAl, C, P, thiab S
Consistency nyob rau hauv batch, yog li cov hlau ua tau zoo ib yam li txhua lub sijhawm
Ob tus neeg muag khoom tuaj yeem muag "FeSi75," tab sis yog tias ib tus neeg muaj cov khoom tsis ruaj khov lossis cov khoom tsis sib xws, cov neeg yuav khoom yuav xav tias nws nyob hauv kev tsim khoom-los ntawm kev hloov pauv hloov pauv lossis kev hloov pauv tsis tau xav txog steel chemistry.
Q2: Dab tsi impurity ntsiab yuav tsum cov neeg yuav khoom them siab tshaj plaws rau?
Kev tsom xam yog nyob ntawm qib steel, tab sis cov no yog cov feem ntau kuaj:
Phosphorus (P):tuaj yeem ua kom brittleness thiab ua kom puas tsuaj
Sulfur (S):tuaj yeem txo cov ductility thiab ua rau lub ntsej muag tsis zoo
Aluminium (Al):tuaj yeem cuam tshuam txog kev suav nrog thiab qee zaum kev coj cwj pwm
Cov pa roj carbon (C):tej zaum yuav cuam tshuam cov pa roj carbon tswj hauv qee cov txheej txheem
Rau cov qib hlau huv huv, cov neeg yuav khoom feem ntau thov txwv tsis pub P thiab S. Rau cov hlau hluav taws xob lossis cov txheej txheem rhiab ntau dua, kev ruaj ntseg ntawm impurities tseem ceeb dua.
Q3: Cov ntaub ntawv dab tsi lossis cov kev xeem uas nquag siv los txheeb xyuas FeSi zoo?
Cov cuab yeej pov thawj feem ntau yog covCOA (Certificate of Analysis). COA zoo meej qhia Si thiab impurity qhov tseem ceeb rau cov khoom xa tuaj.
Nyob rau hauv tas li ntawd, buyers feem ntau cia siab rau:
Ua ntej-kev tshuaj ntsuam xyuas khoom xa tuaj (PSI) cov duab lossis cov ntawv ceeb toom
Thib peb -kev kuaj simntawm tus qauv (tshwj xeeb tshaj yog rau kev txiav txim loj)
Kev tshuaj xyuas tuajtom qab tuaj txog, suav nrog kev kuaj tshuaj lom neeg thiab kuaj qhov loj me
Yog tias qhov kev txiav txim loj los yog daim ntawv thov nruj, cov neeg yuav khoom tuaj yeem thov taukhaws cov qauvlos yog ib qho kev pom zoo sampling txoj kev ua ntej loading.
Q4: Yuav ua li cas cov neeg yuav khoom yuav txo tau qhov kev pheej hmoo ntawm kev tsis zoo thaum importing?
Nov yog ob peb kauj ruam uas yuav pab tau ntau yam:
Paub meej tus qauv tseeb(Si ntau yam thiab impurity txwv) ua ntej kos npe
Thov COA tsis ntev los nolos ntawm tib tus neeg muag khoom los xyuas qhov sib xws
Qhia particle loj thiab max nplua, vim tias kev nplua ntau dhau tuaj yeem ua rau plua plav poob thiab rov qab tsis ruaj khov
Txheeb xyuas cov ntim thiab tiv thaiv noo noo, tshwj xeeb tshaj yog rau cov me me xws li 0-3mm lossis 1-5mm
Pib nrog kev txiav txim mus sib haisyog tias nws yog tus neeg xa khoom tshiab lossis daim ntawv thov nkag siab
Ntau qhov teeb meem zoo tshwm sim tsis yog vim cov khoom siv yog "dag," tab sis vim tias qhov kev cia siab tsis tau sau meej meej rau hauv qhov kev txiav txim.
Q5: Tus neeg muag khoom txhim khu kev qha feem ntau ua li cas kom purity ruaj khov?
Cov neeg muag khoom uas tuaj yeem tswj hwm kev ruaj khov purity feem ntau ua ntau yam tsis tu ncua:
Siv cov khoom siv raw khoom ruaj khov
Tswj lub qhov cub ua haujlwm thiab ua tib zoo tapping
Ua qhov kev kuaj sim niaj hnub thiab QC sab hauv
Cais cov khoom raws qib thiab tsis txhob hla- kis kab mob
Ua kom ruaj khov crushing / tshuaj xyuas cov txheej txheem kom qhov loj me ntawm kev faib tawm nyob ib puag ncig
Nyob rau hauv luv luv, purity los ntawm cov txheej txheem tswj. Thaum tus neeg muag khoom tus txheej txheem ruaj khov, cov khoom feem ntau yuav ruaj khov thiab.
Hais txog peb cov khoom
Peb muab ferrosilicon qib xws liFeSi75, FeSi72, thiab FeSi65nrog tswj impurities thiab ruaj khov muaj pes tsawg leeg.
Rau cov neeg siv khoom uas xav tau cov khoom siv huv, peb tuaj yeem muab COAs tsis ntev los no, sib tham txog kev txwv tsis pub dhau, thiab txhawb nqa cov qauv lossis kev sim.
Yog tias koj qhia koj daim ntawv thov thiab ntau qhov kev nyiam, peb tuaj yeem pom zoo xaiv qhov tsim nyog thiab muab cov lus qhia FOB tshiab thiab cov ntsiab lus ntim.
