Nruam casting tshuab yog ib qho khoom siv ua tiav casting uas hloov cov hlau ua kua rau hauv qhov loj me.

Kawm txog kev nruam casting

Nruam casting yog txheej txheem uas molten hlau solidifies mus rau hauv ib tug nruam slab, uas yog ces txiav mus rau qhov ntev ntev. Nruam casters yog tsim los hloov cov hlau molten rau hauv cov khoom ib nrab tiav xws li slabs, paj thiab billets. Cov txheej txheem tshem tawm qhov xav tau rau cov tsoos ingot casting, uas yog siv sijhawm ntev thiab tsis muaj txiaj ntsig.

Nruam casting txheej txheem

Cov txheej txheem nruam casting pib los ntawm melting cov ntaub ntawv raw nyob rau hauv ib tug hluav taws xob arc rauv los yog oxygen converter. Thaum cov hlau ncav cuag qhov ntsuas kub thiab muaj pes tsawg leeg, nws yog poured rau hauv ladles thiab xa mus rau lub nruam caster.

Pwm: Ncuav molten hlau rau hauv dej txias pwm thiab pib solidification. Pwm feem ntau yog ua los ntawm tooj liab, uas muaj cov thermal conductivity zoo heev rau kev hloov hluav taws xob zoo.

Solidification: Raws li cov hlau molten dhau los ntawm pwm, nws txias thiab solidifies. Lub thickness ntawm lub plhaub solidified yog ua tib zoo tswj kom ntseeg tau tias uniformity.

Pull Out: Lub nruam caster rub lub pob zeb uas muaj zog tawm ntawm lub crystallizer ntawm kev tswj ceev. Qhov kev rho tawm no yog qhov tseem ceeb vim nws cuam tshuam rau qhov zoo ntawm cov khoom kawg.

CUTING: Thaum cov hlau ncav cuag qhov ntev ntawm qhov xav tau, nws raug txiav mus rau hauv cov khoom tswj tau xws li slabs, paj, lossis billets, nyob ntawm daim ntawv thov.

Txias: Tom qab txiav, cov khoom ib nrab ua tiav tau txias ntxiv rau hauv lub txaj txias ua ntej thauj mus rau kev ua haujlwm ntxiv lossis cia.

Hom kev nruam casting tshuab

Kev nruam casting tshuab tuaj yeem raug cais raws li cov duab ntawm cov khoom kawg:

Slab Caster: Cov tshuab no tsim cov slabs uas feem ntau dov rau hauv cov ntawv los yog daim hlau.

Loj Square Casters: Loj square casters tsim cov khoom lag luam nrog cov ntu loj dua thiab feem ntau yog siv rau hauv cov qauv siv.

Billet Caster: Lub billet caster tsim cov khoom lag luam nrog cov ntu me me thiab feem ntau yog siv los tsim cov pas nrig, pas nrig thiab lwm yam khoom ntev.

Txhua hom nruam caster yog tsim los nrog cov yam ntxwv tshwj xeeb los txhim kho cov txheej txheem casting kom tau raws li cov khoom xav tau.

Qhov zoo ntawm kev nruam casting tshuab

Kev siv cov tshuab nruam casting coj ntau yam zoo rau cov hlau ntau lawm:

1. Txhim kho efficiency

Lub tshuab nruam casting ua haujlwm tsis tu ncua kom ua tiav cov txheej txheem ntau lawm. Qhov no yog qhov sib piv rau cov txheej txheem casting, uas yuav tsum tau siv sij hawm siv cov txheej txheem xws li cua txias thiab tuav tus kheej ingots. Qhov txuas ntxiv ntawm cov txheej txheem nce yields thiab shortens lub sij hawm ntau lawm.

2. Txhim kho qhov zoo

Cov txheej txheem nruam nruam txo qhov kev pheej hmoo ntawm kev tsis xws luag hauv cov khoom siv, xws li kev sib cais thiab porosity. Tswj cov cua txias thiab cov khoom sib xws hauv cov caster tsim cov hlau zoo dua nrog cov khoom siv kho kom zoo dua qub.

3. Txo cov khoom pov tseg

Los ntawm kev tsim cov khoom semi-tiav ncaj qha los ntawm molten steel, nruam casters ho txo ​​cov khoom pov tseg. Cov txheej txheem tshem tawm qhov xav tau rau kev tuav thiab ua cov khoom siv ntxiv, uas ua rau txoj kev tsim khoom ruaj khov dua.

4. Kev ua tau zoo

Kev ua tau zoo thiab kev txhim kho zoo cuam tshuam nrog kev nruam nruam tuaj yeem ua rau txo nqi rau cov neeg tsim khoom steel. Txo kev siv hluav taws xob, txo cov nqi zog thiab txo cov khoom pov tseg kom tsawg ua rau muaj kev lag luam ntau dua.

5. Yooj yim

Niaj hnub nimno nruam casting tshuab yog tsim los kom haum rau ntau hom steel qib thiab cov khoom tsim. Qhov kev hloov pauv no tso cai rau cov tuam txhab lag luam teb sai sai rau kev lag luam xav tau thiab tsim cov khoom lag luam customized raws li xav tau.

Qhov cuam tshuam ntawm kev nruam casting ntawm kev lag luam steel

Kev taw qhia ntawm cov tshuab nruam nruam tau muaj kev cuam tshuam loj heev rau kev lag luam steel. Txij li thaum nws cov kev taw qhia nyob rau hauv 1950s, nruam casting tau dhau los ua txoj kev tseem ceeb ntawm steel ntau lawm thoob ntiaj teb. Qhov kev hloov pauv no tau ua rau ntau qhov kev txhim kho tseem ceeb:

1. Kev loj hlob ntawm kev tsim khoom thoob ntiaj teb

Kev nruam nruam tso cai rau cov neeg tsim khoom steel kom nce ntau lawm. Lub peev xwm ua tau zoo tsim cov khoom loj ntawm cov hlau zoo ua rau kev loj hlob tag nrho ntawm kev lag luam steel thoob ntiaj teb.

2. Kev kawm txuj ci

Cov txheej txheem nruam nruam txhawb kev tsim kho thev naus laus zis hauv kev tsim cov hlau. Kev nce qib hauv automation, kev soj ntsuam cov tshuab thiab cov ntaub ntawv tshawb fawb tau txhim kho kev ua tau zoo thiab kev ntseeg siab ntawm cov casters tas li, ntxiv rau lawv cov kev ua tau zoo.

3. Kev pab cuam ib puag ncig

Txo cov khoom pov tseg thiab kev siv hluav taws xob cuam tshuam nrog kev nruam nruam ua rau kev tsim cov hlau ruaj khov dua. Raws li kev lag luam ntsib kev nyuaj siab los txo nws txoj kev cuam tshuam rau ib puag ncig, cov casters txuas ntxiv ua lub luag haujlwm tseem ceeb hauv kev ua tiav cov hom phiaj no.

4. Txhim khu kev sib tw

Steel manufacturers siv nruam casting technology tau txais kev sib tw kom zoo dua hauv kev ua lag luam. Lub peev xwm los tsim cov khoom lag luam zoo ntawm cov nqi qis tso cai rau cov tuam txhab no kom tau raws li cov neeg siv khoom xav tau ntau dua thiab tswj tau cov txiaj ntsig.

nyob rau hauv xaus

Nruam casters yog lub hauv paus ntawm kev tsim cov hlau niaj hnub, hloov cov hlau molten rau hauv cov khoom lag luam ib nrab nrog kev ua haujlwm zoo thiab zoo. Raws li kev lag luam steel txuas ntxiv txhim kho, qhov tseem ceeb ntawm kev siv tshuab nruam nruam tsuas yog loj hlob. Nrog nws cov txiaj ntsig ntau, suav nrog kev ua kom zoo dua qub, txhim kho kev ua tau zoo, txo cov khoom pov tseg thiab cov nqi siv tau zoo, cov casters txuas ntxiv yuav nyob twj ywm ntawm qhov ua ntej ntawm kev tsim steel rau xyoo tom ntej. Raws li cov neeg tsim khoom siv cov thev naus laus zis no, lawv yuav tsis tsuas yog ua kom muaj peev xwm ntau lawm tab sis kuj tseem pab txhawb kev txhim kho kom ruaj khov thiab kev sib tw ntawm kev lag luam steel.
