Dab tsi "MH" Tiag Tiag Qhia rau koj - Thiab yog vim li cas nws tsis yog tib lo lus nug li N vs J
Qhov "M" hauv MH txhais tau tias cov hlau yogthermomechanically dov: lub strip yog kub- dov nrog kev tswj qhov kub thiab txias los ntawm qhov kawg dov hla dhau, ua raws li kev ua kom txias txias, yog li cov nplej ua kom zoo zoo tshwm sim thaum dov nws tus kheej es tsis yog nyob rau hauv nyias cov cua sov- cov kauj ruam tom qab kho. Qhov no yog ib txoj kev sib txawv ntawm "N" (normalized) tus me nyuam tus mob, qhov twg lub kauj mus los ntawm dov thiab ces ib tug txawv normalizing tshav kub kev kho mob los kho cov grain qauv tom qab qhov tseeb.
Cov tswv yim sib txawv tshwm sim hauv chemistry, tsis yog tus nqi txheej txheem xwb. Txhawm rau ntaus tib lub zog hauv chav kawm, TM dov ua tiav cov txiaj ntsig zoo yam tsis xav tau ntau npaum li cov pa roj carbon lossis alloying, uas yog vim li cas MH- cov khoom siv qib feem ntau nqa qis carbon sib npaug (CEV) dua li JR / J0H / J2H txoj hauv kev ntawm tib lub zog tawm los. Tsawg CEV txhais tau tias yuav tsum tau ua kom sov tsawg dua thiab muaj kev zam txim ntau dua ntawm cov txheej txheem vuam - cuam tshuam lub sijhawm lub raj no tau txiav, coped, thiab welded rau hauv ib lub thav duab es tsis yog tsuas yog thauj khoom hauv compression.
Vim li cas "Mill" hauv Cov Lus Tshawb Nrhiav tsis yog qhov xwm txheej
Cov neeg yuav khoom nrhiav "mill square hollow section" feem ntau yog qhov txawv ntawm cov khoom lag luam - txiav cov khoom, thiab qhov sib txawv yog tiag tiag, tsis yog cov khoom siv - saw nyiam.
Mill- ncaj qha square hollow seem los nrog ib daim ntawv pov thawj uas taug qab cov seem rov qab mus rau ib qho tshwj xeeb cam khwb cia / cua sov tooj los ntawm qhov kev tsim khoom no - EN 10204 3.1 daim ntawv pov thawj teev cov tshuaj muaj pes tsawg leeg thiab cov txiaj ntsig ntawm cov tshuab ntsuas cua sov, tsis yog cov ntaub ntawv qib generic. Cov khoom lag luam, tshwj xeeb tshaj yog tias re- txiav los ntawm qhov ntev zeb ntev lossis sib sau ua ke thoob plaws ntau qhov cua sov, tuaj yeem poob qhov ntawd ib qho - mus rau - ib qho kev taug qab tshwj tsis yog tus neeg khaws khoom tshwj xeeb tau khaws cia thiab dhau los ntawm cov ntaub ntawv kub ib ntus.
Rau feem ntau cov fabrication no tsis muaj teeb meem. Nws pib muaj teeb meem thaum qhov project specification hu rau tag nrho cov ntaub ntawv traceability (feem ntau ntawm cov qauv steel cov hauj lwm tswj los ntawm EN 1090 execution class EXC3/EXC4), los yog thaum ib tug fabricator xav kom phim CEV thiab txhua yam khoom precisely hla ib welded los ua ke es tsis xav tias "S275 yog S275."
Case hauv point:Tus txheej txheem fabricator nrhiav S275MH SHS rau ib qho EXC3- ntsuas thav duab tau txais cov khoom siv los ntawm ob qhov sib txawv nruab nrab ntawm - qhov project tom qab hloov pauv stockist. Ob qho khoom siv tau ntsib S275MH ntawm daim ntawv, tab sis cov ntawv pov thawj zeb tau pom qhov sib txawv CEV ntawm kwv yees li 0.03% ntawm cov cua sov - me me, tab sis txaus tias tus kws tsim cov khoom siv vuam xav tau ob qhov sib cais WPS validations es tsis txhob ntawm ib, ntxiv ib lub lis piam rau cov txheej txheem vuam kev pom zoo ua ntej fabrication yuav rov pib dua. Thov ib zaug - cua sov, zeb-ncaj mov rau tag nrho tonnage ntawm kev txiav txim theem yuav zam tau qhov kev ncua tag nrho.
MH vs MLH - Cov Lus Nug Txog Cov Neeg Yuav Khoom Feem Ntau Nco
S275MH thiab S275MLH muaj cov txiaj ntsig zoo sib xws. Qhov txawv yog Charpy cuam tshuam qhov ntsuas kub: MH raug kuaj thiab lav ntawm 20 degree, thaum MLH txuas rau tib qhov lav mus rau -20℃. Rau cov qauv nyob rau hauv unheated sab nrauv tej yam kev mob, low- huab cua kub, los yog ib yam dab tsi uas muaj feem xyuam rau tiag tiag - loading txaus ntshai, MLH yog qhov tseeb hu - thiab nws feem ntau tsis yog ib tug loj tus nqi nce yog txiav txim raws li ib feem ntawm cov thawj zeb khiav es tsis thov tom qab qhov tseeb los ntawm stocked MH cov ntaub ntawv.
FAQ
Q: Puas yog MH raug nqi ntau dua li qib J0H / J2H rau tib lub zog S275?
A: Feem ntau yog tus nqi qis, khi rau TM dov txheej txheem thiab qis dua -CEV chemistry tswj, tsis yog chav kawm sib txawv. Tus nqi yog feem ntau tsim nyog nws tsuas yog thaum weldability / CEV lossis tag nrho zeb traceability tiag tiag tseem ceeb rau qhov project.
Q: S275MH puas tuaj yeem hloov nrog S275J2H ntawm tib txoj haujlwm?
A: Tsuas yog tias tus qauv tsim thiab vuam txheej txheem tsis cia siab rau qis CEV lossis Charpy lav. Txheeb xyuas qhov project spec - EN 1090 execution classes saum EXC2 feem ntau qhia qhov kev xa khoom kom meej, tsis yog qib zog xwb.
Q: Puas yog MLH ib txwm zoo dua MH?
A: Tsis tau txais - MLH ntxiv qhov qis- qhov kub thiab txias tau lees paub tias feem ntau sab hauv lossis me me- huab cua cov qauv tsis xav tau. Qhia meej tias nws yog lub neej ntawd thaum nws tsis tas yuav tsuas yog nqaim koj cov pob zeb muaj.
Q: Dab tsi yog daim ntawv pov thawj zeb tiag tiag xav tau los qhia rau tag nrho traceability?
A: Ib daim ntawv pov thawj EN 10204 3.1 khi rau ib qho hluav taws xob tshwj xeeb / cam khwb cia, nrog rau cov tshuaj lom neeg muaj pes tsawg leeg thiab cov txiaj ntsig ntawm cov khoom siv rau cov cua sov ntawd - tsis yog daim ntawv teev cov khoom lag luam. Nug tshwj xeeb rau cov cua sov- cov ntawv pov thawj txuas yog tias qhov project xav tau nws.
