Kub Rolled Txheem Hlau H-Beams S275J {2}}

S275J {{{1} h-nqaj yog kub yob cov qauv txheej txheem hauv qab Europe: 2004, uas tau siv dav hauv kev tsim kho, engineering thiab kev siv khoom.

Raws li cov khoom kub kub dov, s275J {1}} h-ingot) thiab dhau los ntawm cov txheej txheem H-ingot) thiab dhau los ntawm kev ua kom muaj zog ntawm H-ingno (li 1200 tus txheej txheem tsim nyog rau cov ntawv thov.

Kub Rolling Kev Tsim Khoom ntawm S275J {1}} h-nqaj
Cua sov: lub billet lossis slab yog rhuab nyob rau hauv lub cub tawg mus txog 1200 degree.
Dov
Txias: Lub H-nqaj tom qab dov yog txias ib txwm los yog tswj kom ua tiav cov khoom siv uas xav tau.
Xov: nto (oxide) tsim thaum lub sij hawm dov ib txwm yog tshem siv cov hlau dej siab los yog cov qauv siv tshuab kom ntseeg tau tias yog qhov chaw du.

Raws li Flange Dav, Kub dov H-nqaj tau muab faib ua cov hauv qab no:

HW (dav flange): Flange dav yog kwv yees sib npaug rau nqaj nqaj.

HM (nruab nrab flange): Flange dav yog tsawg dua qhov tob.

Hn (nqaim flange): Flange dav yog tsawg dua qhov tob.

S275J {0 beams} h-nqaj hlau muaj nyob rau ntau qhov ntau thiab tsawg hauv European cov qauv xws li en 10034 (cov qauv txheej txheem steel h-nqaj). Qhov ntau thiab tsawg cov khoom muaj:

Qhov siab (h): 100 hli rau 1000 mm.

Flth Dav (B): 50 hli rau 400 hli.

Web Thickness (T1): 4.5 hli rau 20 hli.

Flange tuab (T2): 6 hli rau 35 hli.

Ntev: Feem ntau 6m, 9m, 12m lossis kev cai ntev txog 20m.

S275J {0 h nqaj qauv muaj nyob hauv ntau lub xeev raws li en {2}}:
Raws li dov (+ ar): xa tawm yam tsis muaj tshwj xeeb dov lossis kev kho cua sov.
Normalized dov (+ n): Rolled nyob rau hauv kev tswj hwm kub ntau yam kom ua tiav cov khoom piv rau qhov qub.
Thermomecthahanically dov (+ m): dov kom ua tiav cov khoom uas tsis tuaj yeem rov ua dua los ntawm kev kho kom sov.

Zoo ntawm S275J {1}} hect hlau
Cov Txheej Txheem Kev Ua Tau: H-Shares muaj lub zog siab-rau-qhov hnyav piv, ua rau lawv zoo tagnrho rau kev txhawb nqa hnyav.
Tus nqi-ua tau zoo: Cov ntsiab lus muaj peev xwm ntawm cov roj carbon qis thiab cov txheej txheem ntau lawm ua rau lawv muaj kev sib tw luv nqi.
Versatility: muaj nyob rau ntau qhov ntau thiab tsawg, yooj yim rau weld, txiav lossis daim ntawv.
Tougness: zoo cuam tshuam tsis kam ntawm 0 degree, haum rau huab cua huab cua.

Gnee steel tau tsim tsa nyob rau xyoo 2008, peb cov khoom tseem ceeb yog seem steel, lub tsev sib luag, thiab lwm yam. Peb zoo siab los muab koj tus nqi zoo tshaj plaws thiab cov lus qhia. Koj zoo siab tos txais koj mus ntsib peb lub tuam txhab.
