Q235B Seamless Square Yeeb Nkab

Q235B seamless square tube yog ib qho uas nquag siv carbon structural steel seamless steel raj nrog ntau yam kev siv thiab cov yam ntxwv ua tau zoo. Cov hauv qab no yog cov ncauj lus kom ntxaws txog Q235B seamless square raj:

1. Cov yam ntxwv ntawm cov khoom
Cov tshuaj muaj pes tsawg leeg: Q235B seamless square tube yog tsim los ntawm carbon, silicon, manganese, sulfur, phosphorus thiab lwm yam ntsiab lus, uas cov ntsiab lus carbon yog nyob nruab nrab ntawm 0.12% thiab 0.20%, xyuas kom meej qhov yooj yim lub zog thiab hardness ntawm cov hlau. Nyob rau tib lub sijhawm, tus nqi tsim nyog ntawm manganese txhim kho lub hardenability thiab lub zog ntawm cov hlau, thaum cov ntsiab lus ntawm cov ntsiab lus xws li silicon, sulfur thiab phosphorus yog nruj me ntsis tswj xyuas kom cov purity thiab kev ua tau zoo ntawm cov hlau.
Cov khoom siv kho tshuab: Q235B seamless square raj muaj lub zog muaj zog thiab lub zog tensile, feem ntau lub zog tawm los tsis tsawg dua 235MPa, thiab lub zog tensile yog nruab nrab ntawm 375MPa thiab 500MPa. Qhov no ua rau cov khoom siv los tiv thaiv kev thauj khoom loj thiab cuam tshuam, thiab tsim nyog rau kev tsim khoom ntawm ntau yam qauv.
Lwm yam khoom: Q235B seamless square raj kuj muaj cov yas zoo thiab tawv, thiab tuaj yeem ua rau qee yam yas deformation thaum raug kev ntxhov siab yam tsis tau tawg yooj yim, uas txhim kho kev nyab xeeb thiab ruaj khov ntawm cov qauv. Nyob rau tib lub sijhawm, cov khoom siv kuj muaj kev ua haujlwm vuam zoo, uas yooj yim rau vuam thiab kev sib txuas nrog lwm cov ntaub ntawv hlau, thiab yooj yim rau kev tsim kho.
2. Cov txheej txheem ntau lawm
Cov txheej txheem tsim khoom ntawm Q235B seamless square raj feem ntau suav nrog cov kauj ruam xws li kev npaj cov khoom siv raw, cua sov, perforation, dov, sizing, txias, straightening, soj ntsuam thiab ntim. Ntawm lawv, perforation thiab dov yog cov kauj ruam tseem ceeb hauv cov txheej txheem tsim khoom, thiab cov hlau billet tau ua tiav rau hauv cov yeeb nkab steel seamless los ntawm ob kauj ruam no. Thaum lub sij hawm cov txheej txheem ntau lawm, tsis xws li cua sov kub, dov ceev thiab txias txoj kev yuav tsum tau nruj me ntsis tswj los xyuas kom meej qhov tseeb dimension thiab kev ua tau zoo ntawm seamless square raj.

3. Daim ntawv thov teb
Q235B seamless square raj yog nyiam rau nws cov kev ua tau zoo heev thiab daim ntawv thov dav. Cov hauv qab no yog nws lub ntsiab daim ntawv thov teb:

Kev tsim kho: Q235B seamless square raj yog dav siv rau hauv kev txhawb nqa, ncej, nqaj thiab kem ntawm lub tsev qauv, thiab muab kev txhawb nqa zoo rau lub tsev nrog nws lub zog siab thiab zoo plasticity. Nyob rau tib lub sijhawm, cov khoom siv kuj tuaj yeem siv los tsim cov khoom siv hauv tsev xws li ntaiv thiab guardrails.
Mechanical field: Hauv kev tsim khoom siv tshuab, Q235B seamless square raj feem ntau yog siv los tsim ntau yam khoom siv kho tshuab, cov cuab yeej cuab tam, thiab lwm yam kom tau raws li qhov yuav tsum tau ua ntawm txhua yam muaj zog thiab ruaj khov. Nws cov kev ua haujlwm zoo thiab kev ua haujlwm vuam ua rau cov khoom siv no muaj kev thov dav dav hauv kev tsim khoom siv tshuab.
Tsheb teb: Hauv kev tsim tsheb, Q235B seamless square raj feem ntau yog siv los tsim cov qauv ntawm lub cev, chassis thiab lwm qhov chaw los txhim kho lub peev xwm thauj khoom thiab kev nyab xeeb ntawm tsheb. Lub zog siab thiab toughness ntawm cov khoom no ua rau cov qauv tsheb ruaj khov thiab ruaj khov.
Lwm qhov chaw: Tsis tas li ntawd, Q235B seamless square tubes tseem tuaj yeem siv rau hauv kev tsim khoom nkoj, kev tsim kho choj, cov khoom siv tshuaj thiab lwm yam kev ua haujlwm kom tau raws li cov qauv tsim hauv ntau qhov chaw ib puag ncig.
