Square raj yog cov khoom siv tseem ceeb rau kev tsim kho thoob ntiaj teb thiab kev tsim kho tshiab, nrog rau ntau yam kev siv thiab ntau yam. Raws li cov duab sib txawv, cov raj square feem ntau muab faib ua plaub pawg: profiles, phaj, kav dej, thiab cov khoom hlau. Txhawm rau kom yooj yim rau kev tsim khoom, xaj, xa khoom, thiab kev tswj hwm cov raj square, lawv tau siv dav.
1. Lub tswvyim ntawm square tube:
Square tubesyog cov ntaub ntawv tsim los ntawm steel ingots, billets, los yog square tubes los ntawm kev ua haujlwm siab kom tau raws li peb cov duab, qhov ntau thiab tsawg, thiab cov khoom.
Square raj yog ib qho tseem ceeb thiab cov khoom siv tseem ceeb rau kev tsim kho thiab kev ua tiav ntawm plaub qhov kev hloov kho tshiab hauv Suav teb. Nws yog dav siv thiab muaj ntau yam ntawm ntau yam. Raws li qhov sib txawv ntawm qhov sib txawv, cov raj square feem ntau muab faib ua plaub pawg: profiles, phaj, kav dej, thiab cov khoom hlau. Txhawm rau pab txhawb lub koom haum ntawm square tube ntau lawm, kev txiav txim thiab muab khoom, thiab txhim kho kev tswj hwm kev lag luam.
2. Txoj kev tsim cov raj square
Feem ntaulub cevKev ua haujlwm muaj cov yas deformation ntawm cov txheej txheem steel (billets, ingots, thiab lwm yam) los ntawm kev ua haujlwm siab. Raws li kev ua haujlwm kub ntawm square tube, lub raj square tuaj yeem muab faib ua kev ua haujlwm txias thiab kub ua haujlwm. Cov txheej txheem tseem ceeb rau cov raj square muaj xws li:
Rolling: Ib txoj kev ua haujlwm siab nyob rau hauv uas square tube hlau billets dhau los ntawm qhov khoob (ntau yam duab) ntawm ib khub ntawm cov rotating rollers, thiab cov khoom hla ntu txo qis thiab qhov ntev nce vim qhov compression ntawm cov menyuam. Qhov no yog ib txoj kev siv ntau lawm rau square tube ntau lawm, feem ntau yog siv los tsim square tube profiles, daim hlau, thiab kav. Muab faib ua txias dov thiab kub dov.
Rolling: Ib txoj kev ua haujlwm siab nyob rau hauv uas square tube hlau billets dhau los ntawm qhov khoob (ntau yam duab) ntawm ib khub ntawm cov rotating rollers, thiab cov khoom hla ntu txo qis thiab qhov ntev nce vim qhov compression ntawm cov menyuam. Qhov no yog ib txoj kev siv ntau lawm rau square tube ntau lawm, feem ntau yog siv los tsim square tube profiles, daim hlau, thiab kav. Muab faib ua txias dov thiab kub dov.
Forged square tube: Ib txoj hauv kev ua haujlwm siab uas siv lub zog reciprocating ntawm lub forging rauj lossis lub siab ntawm cov xovxwm los hloov qhov khoob rau hauv cov duab thiab qhov loj me uas peb xav tau. Nws feem ntau muab faib ua dawb forging thiab tuag forging, thiab feem ntau yog siv los tsim cov ntaub ntawv uas muaj qhov loj ntawm qhov loj me xws li cov ntaub ntawv loj thiab cov ntawv loj.
Rub lub raj square: yog hais txog cov txheej txheem ntawm kev kos duab dov hlau billets (cov duab, cov raj, cov khoom, thiab lwm yam) los ntawm cov qhov tuag kom txo tau qhov hlais thiab nce qhov ntev. Nws feem ntau yog siv rau kev ua haujlwm txias.
Extrusion: Ib txoj kev ua nyob rau hauv uas ib lub raj square tso hlau nyob rau hauv lub kaw extrusion chamber thiab siv lub siab ntawm ib kawg kom extrude cov hlau los ntawm ib tug tshwj xeeb pwm qhov kom tau tiav cov khoom ntawm tib lub puab thiab loj. Nws yog feem ntau siv nyob rau hauv zus tau tej cov non-ferrous hlau square raj
3. Ferrous, steels thiab non-ferrous hlau
Ua ntej qhia txog kev faib cov hlau, luv luv qhia cov ntsiab lus ntawm Ferrous,square tube steelthiab nonferrous hlau.
1. Ferrous hais txog hlau thiab nws cov alloy. Xws li steel, npua hlau, ferroalloys, cam khwb cia hlau, thiab lwm yam. Hlau thiab npua hlau yog alloys raws li cov hlau square tubes, nrog carbon raws li lub ntsiab ntxiv ntsiab, collectively hu ua hlau carbon alloys.
Npua hlau yog hais txog cov khoom tsim los ntawm smelting hlau ore rau hauv lub qhov cub tawg, feem ntau yog siv rau steelmaking thiab square tube manufacturing ntawm castings. Casting npua hlau yog melted nyob rau hauv lub molten hlau cub kom tau cam khwb cia hlau (kua). Cov kua cam khwb cia hlau yog cam khwb cia rau hauv ib lub raj square, thiab hom cam khwb cia hlau no hu ua cam khwb cia hlau.
Ferroalloy yog ib qho alloy uas muaj hlau thiab silicon, manganese, chromium, titanium thiab lwm yam khoom. Ferroalloy yog ib qho ntawm cov khoom siv raw rau steelmaking. Nws yog siv los ua Oxygen scavenger thiab alloy element additive rau steel hauv square tube steelmaking.
2. Muab npua hlau rau steelmaking rau hauv steelmaking rauv thiab yaj nws raws li ib tug txheej txheem kom tau hlau. Cov khoom ntawm cov hlau muaj xws li ingots, nruam casting billets, thiab ntau yam steel castings tsim los ntawm square yeeb nkab ob leeg casting. Feem ntau hu ua steel feem ntau yog hais txog steel dov mus rau hauv ntau lub square tubes. Square tube steel belongs rau Ferrous, tab sis hlau tsis yog sib npaug rau dub kub
