Hauv steelmaking, tus nqi tiag tiag ntawm cov khoom siv refining tsis yog nws tus nqi yuav khoom xwb. Tus nqi qis dua - alloyed nqi tsis yog ib txwm txhais tau tias tus nqi qis dua, tshwj xeeb tshaj yog thaum tswj cov sulfur, suav nrog kev hloov kho, thiab kev ruaj ntseg casting.
Tias yog vim li cas ntau cov nroj tsuag steel ntsuas calcium silicon tsis yog los ntawm tus nqi tuj, tab sis los ntawm nws cov kev cuam tshuam rau tag nrho cov txheej txheem. Hauv cov ntsiab lus no,Ca31Si60 calcium silicon alloyfeem ntau xaiv tsis yog vim nws yog qhov kev xaiv pheej yig tshaj plaws ntawm daim ntawv, tab sis vim tias nws tuaj yeem pab txo tus nqi tag nrho ntawm cov hlau ntau lawm thaum siv nyob rau hauv txoj cai txheej txheem.
Vim Li Cas Tag Nrho Cov Nqi Tseem Ceeb Ntau Dua Tus Nqi Nqi
Hauv kev xyaum, steelmaking tus nqi cuam tshuam los ntawm ntau tshaj li tus nqi ntawm cov khoom ntxiv. Cov khoom siv refining tuaj yeem cuam tshuam:
- desulfurization efficiency
- steel huv
- nozzle clogging zaus
- casting stability
- kev siv alloy
- yield thiab rework txaus ntshai
Yog tias cov khoom siv txhim kho kev ua kom zoo dua qub thiab txo cov teeb meem hauv qab, nws yuav txo qis tag nrho cov nqi tsim khoom txawm tias tus nqi yuav khoom siab dua me ntsis.
Qhov no yog qhov uas Ca31Si60 qhia nws tus nqi.
Dab tsi ua rau Ca31Si60 txawv
Ca31Si60 yog ib qho siab -calcium calcium silicon alloy feem ntau siv hauv kev ua kom zoo dua qub thiab huv steel ntau lawm. Piv nrog rau qib qis dua -calcium, nws muab cov calcium uas muaj zog dua thiab tsim nyog rau cov ntawv thov uas muaj sulfur tswj thiab suav nrog kev hloov pauv tseem ceeb.
Nws lub luag haujlwm tseem ceeb tsis yog deoxidation xwb. Tus nqi tiag tiag ntawm Ca31Si60 nyob hauvkev kho calciumThaum lub sij hawm refining, tshwj xeeb tshaj yog nyob rau hauv cov txheej txheem uas steel huv si ncaj qha cuam tshuam rau casting thiab zaum kawg khoom zoo.
1. Tsawg Sulfur txhais tau tias txo qis kev pheej hmoo
Ib txoj hauv kev pom tseeb tshaj plaws Ca31Si60 txo tus nqi tag nrho yog los ntawm kev ua haujlwm zoo dua desulfurization.
Hauv molten steel, calcium reacts nrog sulfur los tsim calcium sulfide ruaj khov. Thaum cov sulfur tswj tau zoo dua, cov hlau zoo ua tau zoo dua qub thiab qhov kev pheej hmoo ntawm cov dej tsis zoo yog txo. Qhov no yog qhov tseem ceeb tshwj xeeb rau:
- bearing steel
- siab -lub zog steel
- automotive hlau
- pipeline hlau
- nruam casting qib
Yog tias sulfur tseem tsis ruaj khov, tus nqi zais tsis yog kev ua kom zoo dua qub xwb. Nws tuaj yeem tshwm sim tom qab raws li kev tsis txaus siab zoo, cov khoom lag luam txo qis, lossis poob ntau lawm. Hauv qhov kev nkag siab ntawd, kev tswj cov tshuaj sulfur zoo dua yog tus nqi ncaj qha - tswj kev ntsuas.
2. Kev hloov kho kom zoo dua qub txo cov teeb meem Casting
Lwm qhov txiaj ntsig tseem ceeb yog los ntawm kev tswj hwm kev suav nrog.
Hauv aluminium-tua hlau, cov khoom alumina suav nrog tuaj yeem ua rau muaj teeb meem loj yog tias lawv tsis hloov kho kom raug. Ca31Si60 pab hloov cov kev suav no rau hauv cov ntaub ntawv calcium aluminate uas muaj txiaj ntsig zoo dua qub, uas txhim kho steel huv huv thiab txo qhov kev pheej hmoo ntawm cov nozzle clogging.
Qhov no tseem ceeb vim qhov nozzle clogging ua rau cov nqi tiag:
- cuam tshuam casting
- tsis ruaj khov steel ntws
- nto tsis xws luag
- qis productivity
- ntau lub sijhawm kho
Ib tsob nroj tuaj yeem txuag nyiaj los ntawm kev yuav khoom pheej yig dua, tab sis poob ntau dua los ntawm kev tsis sib haum xeeb. Ca31Si60 pab kom tsis txhob muaj qhov ntxiab ntawd los ntawm kev txhim kho kev suav nrog morphology ntawm theem ua kom zoo.
3. Kev ua kom zoo dua qub tuaj yeem txo cov kev siv alloy
Hauv ntau cov nroj tsuag steel, tus nqi tsis yog hais txog tus nqi ib tuj ntawm CaSi, tab sis hais txog cov khoom siv ntau npaum li cas kom ua tiav cov txiaj ntsig.
Vim tias Ca31Si60 muaj cov ntsiab lus calcium ntau dua, nws feem ntau ua haujlwm tau zoo hauv cov txheej txheem uas yuav tsum tau muaj zog desulfurization ntau dua lossis kev kho mob ntxiv. Hauv cov ntsiab lus siv tau, nws tuaj yeem txhais tau tias:
- sai metallurgical teb
- qis dua qhov yuav tsum tau ua raws li qhov tsim nyog
- tsawg kho ntxiv
- zoo ib yam refining tshwm sim
Thaum cov txheej txheem tswj tau yooj yim dua, cov khoom pov tseg raug txo. Nyob rau tib lub sijhawm, qhov no tuaj yeem txo qis tag nrho cov alloy noj thiab txhim kho tus nqi ntawm txhua qhov cua sov.
4. Tsawg txheej txheem cuam tshuam txhais tau tias tus nqi qis dua
Steelmaking tus nqi yog rhiab heev rau cov txheej txheem cuam tshuam. Kev cuam tshuam me me hauv kev ua kom zoo nkauj thiab casting tuaj yeem tsim kev poob qis hauv lub sijhawm, lub zog, thiab cov zis.
Los ntawm kev pab kom ruaj khov steel zoo ua ntej casting, Ca31Si60 yuav txo tau:
- kev hloov kho kev ua haujlwm tsis tau npaj tseg
- lub sij hawm ntxiv refining
- rov kho dua
- casting ncua
Rau cov nroj tsuag steel khiav tas mus li ntau lawm, txheej txheem kev ruaj ntseg yog qhov tseem ceeb ntawm kev lag luam. Ib qho kev ruaj khov refining additive feem ntau muaj nqis tshaj qhov pheej yig dua tab sis tsawg dua qhov kwv yees.
5. Cov Hlau Txhuas Txhuas Txhawb Cov Khoom Muag Khoom Zoo
Kev txo tus nqi tag nrho tsis yog ib txwm hais txog kev siv nyiaj tsawg. Qee zaum nws yog hais txog kev tsim cov hlau uas xa cov nqi ntau dua.
Yog tias Ca31Si60 pab txhim kho steel huv thiab txo qhov tsis xws luag, cov nroj tsuag yuav tau txais txiaj ntsig los ntawm:
- cov khoom zoo sib xws
- qis downgrade tus nqi
- txhim kho kev lees txais cov neeg siv khoom
- siab dua - qib steel nqi
Hauv lwm lo lus, qhov txiaj ntsig tsis txwv rau lub khw refining. Nws tseem tuaj yeem txhim kho tus nqi lag luam ntawm cov khoom siv hlau kawg.
Qhov twg Ca31Si60 tsim tus nqi tshaj plaws
Ca31Si60 tshwj xeeb tshaj yog muaj txiaj ntsig zoo hauv kev ua haujlwm uas cov kev xav tau zoo siab thiab cov txheej txheem tswj cov teeb meem ntau dua li cov khoom siv yooj yim.
Nws yog feem ntau siv nyob rau hauv:
- ladle rauv refining
- RH refining
- theem nrab metallurgy
- nruam casting npaj
- huv steel ntau lawm
Rau cov qauv qis-requirement steels, qis dua -calcium qib tej zaum yuav txaus. Tab sis rau cov nroj tsuag uas tsim cov hlau huv los yog cuam tshuam nrog sulfur- cov ntaub ntawv siv tau yooj yim, Ca31Si60 feem ntau muab tag nrho cov nqi ua tau zoo dua.
Tus nqi yuav khoom vs Tus nqi ua haujlwm
Ib qho yuam kev hauv kev yuav khoom alloy yog sib piv cov ntaub ntawv tsuas yog los ntawm chav tsev nqi.
Kev sib piv muaj txiaj ntsig zoo dua yog:
- ntau npaum li cas ntxiv rau ib qho cua sov
- ruaj khov qhov kev ua kom zoo zoo li cas
- nws cuam tshuam li cas rau kev coj cwj pwm
- seb nws txo rework lossis txheej txheem poob
- seb nws txhawb kev huv huv dua steel
Los ntawm qhov kev xav ntawd, Ca31Si60 yuav tsum raug ntsuas raws li anqi -kev ua tau zoo alloy, tsis yog siab dua -calcium alloy.
Yuav Ua Li Cas Tau Txais Tus Nqi Zoo Tshaj Plaws los ntawm Ca31Si60
Ca31Si60 tsis cia li txo tus nqi hauv txhua txoj kev. Txhawm rau kom tau txais qhov txiaj ntsig zoo tshaj plaws, nws yuav tsum tau ua raws li kev ua haujlwm zoo.
Cov yam tseem ceeb feem ntau muaj xws li:
- steel kub
- qib oxygen ua ntej ntxiv
- sulfur phiaj
- sijhawm ntxiv
- txoj kev pub mis
- ladle refining xyaum
Thaum kev kho calcium tsis zoo rau lub qhov rais txheej txheem, ib feem ntawm cov nqi hlau yuav poob. Tab sis thaum siv kom raug, Ca31Si60 tuaj yeem txhim kho kev ua kom zoo dua qub thiab txo cov nqi tsim khoom zais.
Kev xaiv ib tus neeg muab kev ntseeg siab kuj muaj feem cuam tshuam tag nrho cov nqi
Tib lub npe qib tsis ib txwm txhais tau tias tib txoj kev ua tau zoo. Hauv cov khoom siv tiag tiag, qhov sib txawv ntawm cov khoom sib txawv, qhov loj me sib xws, ntim, thiab kev xa khoom tuaj yeem cuam tshuam tag nrho cov nqi cog.
Ib tus neeg muag khoom txhim khu kev qha pab txo kev pheej hmoo los ntawm kev muab:
- ruaj khov tshuaj muaj pes tsawg leeg
- zoo ib yam loj faib
- vam khom batch zoo
- khoom xa tuaj raws sijhawm
- clear COA txhawb
Rau cov nroj tsuag steel, cov khoom tsis ruaj khov tuaj yeem tsim kom muaj nqi ntau npaum li cov hlau tsis ruaj khov.
Xaus
Ca31Si60 txo qis steelmaking tag nrho cov nqi tsis yog vim nws cov chemistry, tab sis vim li cas nws cuam tshuam rau tag nrho cov txheej txheem refining thiab casting.
Thaum nws txhim kho sulfur tswj, suav nrog kev hloov kho, kev huv huv steel, thiab kev ruaj ntseg casting, qhov tshwm sim yog qis dua tus nqi zais thoob plaws cov saw hlau. Qhov ntawd yuav suav nrog kev pheej hmoo qis dua, kev cuam tshuam ntawm cov txheej txheem tsawg dua, kev ua tau zoo ntawm cov hlau zoo dua, thiab ntau dua - cov txiaj ntsig steel.
Rau cov nroj tsuag steel tsom rau cov hlau huv huv thiab kev ua haujlwm ruaj khov, Ca31Si60 feem ntau tsis yog cov khoom siv nqi xwb. Nws yog ib tug txheej txheem optimization cuab tam.
