Ferrosilicon 75 (FeSi75) yog siv nyob rau hauv yuav luag txhua txhua steel cog thiab foundry, tab sis buyers tsis yeej ib txwm paub ntau npaum li cas.particle lojtuaj yeem cuam tshuam tus cwj pwm melting thiab tag nrho metallurgical kev ua tau zoo. Txawm hais tias cov tshuaj muaj pes tsawg leeg zoo ib yam, cov qoob loo loj cuam tshuam li cas cov alloy yaj, reacts, thiab pab txhawb rau steel zoo.
Cov lus nug hauv qab no qhia txog cov neeg yuav khoom txawv teb chaws feem ntau nug thaum sim xaiv qhov loj FeSi75 rau lawv cov khoom.
Kev lag luam Q&A
Q1: Vim li cas particle loj tseem ceeb hauv thawj qhov chaw?
Txawm hais tias FeSi75 tau txhais los ntawm nws cov ntsiab lus silicon, lubdaim ntawv lub cevtxiav txim siab sai npaum li cas thiab qhov sib npaug ntawm cov alloy melts hauv molten hlau.
Cov khoom loj dua yaj maj mam, ua kom muaj kev tswj xyuas ntau dua.
Cov khoom me me yaj yuav luag tam sim ntawd, ua rau lawv muaj txiaj ntsig zoo -tuning steel muaj pes tsawg leeg.
Yog li, particle loj cuam tshuam:
- Melting ceev
- Silicon rov qab
- Plua plav poob
- Reaction stability
- Tag nrho efficiency
Qhov no yog vim li cas steel mills thiab foundries feem ntau xaiv ntau qhov sib txawv nyob ntawm seb lawv lub qhov cub thiab qhov sib ntxiv.
Q2: Yuav ua li cas thaum FeSi75 melts sai heev los yog qeeb heev?
Yog lub alloymelts sai heev, nws yuav ua rau:
- Nyias silicon nce nyob rau hauv molten steel
- Cov hmoov av ntau dua
- Txo cov khoom siv silicon vim yog nchuav los yog fumes
Qhov no feem ntau tshwm sim nrog qhov loj me zoo li0-3 hli, tshwj xeeb tshaj yog tias qhov cub kub kub yog siab lossis yog tias txoj kev sib ntxiv tsis tswj tau zoo.
Yog lub alloymelts qeeb heev, cov teeb meem tuaj yeem tshwm sim:
- Kev tiv thaiv qeeb
- Kev faib tawm tsis sib xws ntawm silicon
- Kev rov qab qis dua hauv qee hom rauv taws
Qhov no feem ntau tshwm sim nrog cov khoom lojntau tshaj 50 mm, tshwj xeeb tshaj yog nyob rau hauv me me furnaces.
Qhov zoo tshaj plaws, cov nroj tsuag xaiv qhov loj me uas haum rau lawv cov kev sib tw melting, yog li lawv tau txais kev ruaj khov silicon rov qab yam tsis muaj nkim khoom.
Q3: Qhov loj me me twg yog qhov zoo tshaj plaws rau steelmaking?
Rau feem ntau steel mills,10-50 hliyog qhov kev xaiv zoo tshaj plaws thiab ruaj khov.
Qhov ntau yam no melts ntawm ib tug nruab nrab ceev, kom paub tseeb tias silicon rov qab.
Nws muab qhov sib npaug zoo ntawm:
- Kev ua tau zoo
- Tsawg plua plav
- ruaj khov alloying
Qee lub qhov cub loj dua nyiam10-100 hli, tshwj xeeb tshaj yog thaum lawv ntxiv FeSi75 ncaj qha rau hauv qhov cub.
Ntawm qhov tod tes, refining los yog ladle kev khiav hauj lwm feem ntau xaiv qhov ntau thiab tsawg dua - tsis yog vim lawv xav tau yaj sai, tab sis vim lawv cov txheej txheem xav tau kev hloov kho sai dua.
Q4: Thaum twg kuv yuav tsum siv qhov loj me zoo li 1-5mm lossis 0-3mm?
Fine sizes feem ntau yog siv thaum:
- Lub qhov cub me me
- Kev ua haujlwm yuav tsum tau hloov kho silicon ceev
- Cov hlau yog ntxiv thaum kho ladle
- Secondary refining yog koom tes nrog
Cov khoom zoo no pab cov neeg ua haujlwm kho sai thaum lub sijhawm ua cov txheej txheem steel.
Tab sis vim tias lawv yaj tam sim ntawd, lawv yuav tsum tau ceev faj tuav kom tsis txhob muaj plua plav ntau dhau.
Yog li, qhov loj me me yog qhov ua tau zoo, tab sis lawv kuj tseem zam txim tsawg dua yog tias txoj kev sib ntxiv tsis zoo tswj tau.
Q5: Kuv yuav xaiv qhov loj npaum li cas rau kuv cov khoom?
Tsis muaj universal "zoo tshaj" loj - tsuas yog qhov loj me uas haum koj cov khoom siv thiab lub hom phiaj.
Cov neeg yuav khoom feem ntau xav txog:
- Rauv hom (EAF, IF, ladle furnace)
- Kev tswj qhov kub thiab txias
- Ntxiv sijhawm
- Cia siab tias silicon rov qab
- Tus nqi cuam tshuam ntawm plua plav poob
Piv txwv li:
- EAF thiab cov cub tawg loj→ 10-50mm / 10-100mm
- Casting thiab foundry ua haujlwm→ 3-8mm / 1-5mm
- Ladle refining→ finer qhov ntau thiab tsawg xws li 0-3mm
Qee cov nroj tsuag txawm thovkev cai loj sib tov, xws li 10-30mm, kom ua tiav tus cwj pwm melting smoother.
Hais txog peb cov khoom
Peb muab Ferrosilicon 75 rau ntau qhov ntau thiab tsawg, vim cov nroj tsuag sib txawv muaj cov cwj pwm sib txawv. Qee cov neeg siv khoom siv qhov loj dua rau qhov sib ntxiv ruaj khov, thaum lwm tus nyiam cov nplej zoo rau kev tawg sai dua. Yog tias koj tsis paub meej tias qhov loj npaum li cas rau koj lub qhov cub zoo tshaj plaws, peb tuaj yeem tshawb xyuas cov kev coj ua niaj hnub rau koj cheeb tsam lossis qhia cov ntaub ntawv rov qab los ntawm cov nroj tsuag zoo sib xws. Koj tseem tuaj yeem nug txog tus nqi FOB tshiab lossis cov kev xaiv ntim khoom muaj nyob -peb ib txwm npaj los pab nrog cov ntsiab lus no.
