Cov raj plaub fab yog ib yam khoom siv tseem ceeb rau kev tsim kho thoob ntiaj teb thiab kev niaj hnub, nrog ntau yam kev siv thiab ntau yam. Raws li cov duab sib txawv, cov raj plaub fab feem ntau muab faib ua plaub pawg: cov ntaub ntawv, cov phaj, cov kav dej, thiab cov khoom hlau. Txhawm rau kom yooj yim rau kev tsim khoom, kev txiav txim, kev muab khoom, thiab kev tswj hwm cov raj plaub fab, lawv tau siv dav.
1. Lub tswv yim ntawm lub raj plaub fab:
Cov raj plaub fabyog cov ntaub ntawv ua los ntawm cov hlau ingots, billets, lossis cov raj plaub fab los ntawm kev ua kom siab kom tau raws li peb cov duab sib txawv, qhov loj me, thiab cov khoom.
Cov raj plaub fab yog ib qho khoom siv tseem ceeb thiab tseem ceeb rau kev tsim kho thiab kev ua tiav ntawm plaub qhov kev hloov kho tshiab hauv Suav teb. Nws siv dav thiab muaj ntau yam sib txawv. Raws li cov duab sib txawv, cov raj plaub fab feem ntau muab faib ua plaub pawg: cov ntaub ntawv, cov phaj, cov kav dej, thiab cov khoom hlau. Txhawm rau pab txhawb kev teeb tsa cov raj plaub fab, kev txiav txim thiab kev xa khoom, thiab txhim kho kev tswj hwm kev lag luam.
2. Txoj kev tsim cov raj plaub fab
Feem ntaulub raj plaub fabKev ua cov txheej txheem suav nrog kev hloov pauv yas ntawm cov hlau ua tiav (billets, ingots, thiab lwm yam) los ntawm kev ua kom siab. Raws li qhov kub ua tiav ntawm lub raj plaub fab, lub raj plaub fab tuaj yeem muab faib ua kev ua txias thiab ua haujlwm kub. Cov txheej txheem ua tiav tseem ceeb rau cov raj plaub fab suav nrog:
Dov: Ib txoj kev ua haujlwm siab uas cov hlau billets square tube hla dhau qhov sib txawv (ntau yam duab) ntawm ob lub rollers tig, thiab cov khoom siv hla ntu txo qis thiab qhov ntev nce vim yog qhov nias ntawm cov rollers. Qhov no yog ib txoj kev tsim khoom siv rau kev tsim cov raj square, feem ntau yog siv los tsim cov duab plaub fab, phaj, thiab cov kav dej. Muab faib ua dov txias thiab dov kub.
Dov: Ib txoj kev ua haujlwm siab uas cov hlau billets square tube hla dhau qhov sib txawv (ntau yam duab) ntawm ob lub rollers tig, thiab cov khoom siv hla ntu txo qis thiab qhov ntev nce vim yog qhov nias ntawm cov rollers. Qhov no yog ib txoj kev tsim khoom siv rau kev tsim cov raj square, feem ntau yog siv los tsim cov duab plaub fab, phaj, thiab cov kav dej. Muab faib ua dov txias thiab dov kub.
Forged square tube: Ib txoj kev ua haujlwm siab uas siv lub zog sib pauv ntawm lub rauj forging lossis lub siab ntawm lub tshuab nias kom hloov cov khoom seem mus rau hauv cov duab thiab qhov loj uas peb xav tau. Feem ntau nws muab faib ua kev forging dawb thiab tuag forging, thiab feem ntau yog siv rau kev tsim cov ntaub ntawv nrog cov qhov loj dua xws li cov ntaub ntawv loj thiab billets.
Rub lub raj plaub fab: hais txog txoj kev ua cov hlau dov (cov duab, raj, cov khoom, thiab lwm yam) los ntawm cov qhov tuag kom txo qhov seem thiab ua kom ntev dua. Feem ntau siv rau kev ua txias.
Kev Rho Tawm: Ib txoj kev ua haujlwm uas lub raj plaub fab muab hlau tso rau hauv lub chamber kaw thiab siv lub zog ntawm ib kawg kom rho cov hlau tawm ntawm lub qhov pwm tshwj xeeb kom tau txais cov khoom tiav uas muaj tib lub duab thiab qhov loj. Nws feem ntau siv rau hauv kev tsim cov raj plaub fab uas tsis yog hlau.
3. Cov hlau, cov hlau thiab cov hlau uas tsis yog hlau
Ua ntej qhia txog kev faib tawm ntawm cov hlau, luv luv qhia txog cov ntsiab lus tseem ceeb ntawm Ferrous,lub raj hlau squarethiab cov hlau uas tsis yog hlau.
1. Ferrous yog hais txog hlau thiab nws cov hlau sib xyaw. Xws li hlau, hlau npua, ferroalloys, hlau cam khwb cia, thiab lwm yam. Hlau thiab hlau npua yog cov hlau sib xyaw ua los ntawm cov hlau square tube, nrog rau carbon ua lub ntsiab ntxiv, hu ua hlau carbon alloys.
Hlau npua yog cov khoom ua los ntawm kev smelting hlau ore rau hauv lub cub tawg, feem ntau yog siv rau kev ua hlau thiab kev tsim cov yeeb nkab plaub fab. Cov hlau npua casting yog yaj hauv lub cub tawg hlau kom tau txais cov hlau cam khwb cia (kua). Cov hlau cam khwb cia ua kua yog pov rau hauv lub raj plaub fab, thiab hom hlau cam khwb cia no hu ua hlau cam khwb cia.
Ferroalloy yog ib qho hlau sib xyaw ua ke ntawm hlau thiab silicon, manganese, chromium, titanium thiab lwm yam ntsiab lus. Ferroalloy yog ib qho ntawm cov khoom siv raw rau kev ua hlau. Nws yog siv los ua cov pa oxygen scavenger thiab cov khoom siv alloy rau hlau hauv kev ua hlau square tube.
2. Muab cov hlau npua rau kev ua hlau rau hauv lub cub tawg hlau thiab yaj nws raws li ib txoj kev kom tau txais hlau. Cov khoom ntawm hlau suav nrog cov ingots, cov billets casting txuas ntxiv, thiab ntau yam hlau castings tsim los ntawm cov yeeb nkab sib koom ua ke. Cov hlau feem ntau hais txog hlau feem ntau hais txog hlau dov rau hauv ntau lub raj plaub fab. Cov hlau raj plaub fab yog Ferrous, tab sis hlau tsis sib npaug kiag li rau kub dub.
