JIS 3101 SS400 SEEM

JIS G 3101: Tus qauv rau cov qauv kev siv hluav taws xob uas siv cov qauv hlau hauv Japanese muaj cov khoom siv tshuaj lom neeg thiab cov khoom siv neeg kho tshuab).

SS400: Tus qib steel nyob rau hauv tus txheej txheem no, nrog lub zog tensile ntawm 400 MPA, nws yog dav siv hauv cov qauv txheej txheem xws li kev tsim kho thiab tshuab.

Hollow profiles: feem ntau yog hais txog cov square hlab, cov leeg puag ncig, thiab cov pob zeb ua raws li cov khoom siv profile

Tshuaj lom neeg muaj pes tsawg leeg (JIS G 3101 SS400):

Cov pa roj carbon (c): tsawg dua lossis sib npaug rau 0. 29%

Manganese (MN): tsawg dua lossis sib npaug rau 1.40% (kho raws li tuab)

Phosphorus (P), Sulfur (s): tsawg dua lossis sib npaug nrog {{050% (cov sulfur thiab phosphorus kom ntseeg tau weldability)

Cov Khoom Siv Neeg Kho Tshuab:

Paib lub zog: ntau dua los yog sib npaug rau 245 MPa

Lub zog tensile: {400-510 mpa mpa

Elongation: ntau dua los yog sib npaug rau 17% (thaum tuab tsawg dua lossis sib npaug rau 16 hli)
Profile txheem (siv Jis G 3466 ua piv txwv)

Qhov loj me tshwj xeeb:

Square raj \/ duab plaub: Xwb ntev 20 × 20 hli rau 400 × 400 hli, phab ntsa thickness 1. {4 hli.

Cov kav dej puag ncig: cov ntau ntawm cov ciaj ciam dav thiab phab ntsa tuab yog txiav txim siab raws li cov qauv tshwj xeeb.

Txheej txheem tsim khoom:

High-furnency vuam (HFW) lossis kev sib tsoo txias los yog tsim nyog rau cov kav dej nruab nrab thiab nyias muaj nyias cov kav dej.

Cov txheej txheem kub kub yog siv rau cov raj thuv-phab ntsa kom ntseeg tau lub zog.

Qhov Zoo:

Tus nqi ua nqi tau zoo, yooj yim rau cov txheej txheem thiab Weld.

Nws yog dav siv hauv kev tsim cov thav ntawv, xa cov khoom siv, cov khoom siv tshuab, thiab lwm yam.

Txwv:

Lub corrosion kuj yog qhov nruab nrab thiab cov kev kho mob saum npoo (xws li galvanizing thiab tha xim) yuav tsum muaj.

Nws muaj tsis zoo tsawg-kub nyuaj thiab tsis haum rau ib puag ncig txias heev.

Welding: It is necessary to control the input heat to avoid embrittlement of the heat-affected zone. Preheing yog pom zoo rau cov kav hlau tuab-walled.

Cov kev kho deg: Xaiv cov galvanization lossis txheej raws li ib puag ncig los txhim kho corrosion tsis kam.

Tuam Tshoj GB \/ T 6728: Zoo sib xws rau tus qauv ntawm txias-tsim hollow seem steet steel, cov khoom siv Q235 yog benchmarked tiv thaiv ss400.

ASTM A500 ntawm Tebchaws Meskas: Npog Carbon Steel Qauv Kaves, qib B muaj kev ua tau zoo ib yam li SS400.

European EN 10219: Tsim-Tsim Khaub Ncaws Helded Hollow Profiles, nrog cov khoom S235JRH piv.

Kev xaiv lub hauv paus: Xaiv cov phab ntsa tuab thiab cov duab hla sab hauv raws lub thauj khoom thiab ib puag ncig.

Kev Soj Ntsuam Zoo: Cov tsos tshuaj ntsuam, ntsuas Tensile thiab kev twv yuav tau ua raws li JIS cov qauv yog qhov yuav tsum tau ua.

JIS G 3101 SS400 HOLLOW SCILES sib txuas ua ke cov txiaj ntsig ntawm cov khoom siv thiab cov qauv ntaub ntawv thiab yog cov qauv kev lag luam thiab txuag tau zoo thiab txuag tau cov qauv kev siv nyiaj. Thaum txiav txim qhov tseeb, nws yog ib qho tsim nyog kom muaj kev nkag siab cov qauv txheej txheem, ib puag ncig cov txheej txheem kev nyab xeeb thiab ua kom muaj kev nyab xeeb. Hauv kev ua tiav tiag tiag, cov qauv txheem (JIS G 3101) thiab tus qauv profile (xws li JIS G 3466) yuav tsum tau hais meej kom tsis txhob meej pem.
