Cov chaw thov tseem ceeb
JIS G3466 Txheem Hlau Yeeb Nkab Vim tias nws cov kws kho tshuab zoo (lub zog, kev ua tiav) thiab kev ua tiav yooj yim, siv tau ntawm cov hauv qab no:

1. Architecture thiab Civil Engineering
• Tsev cov ncej: siv rau kab teeb, txhua, trusses thiab lwm yam kev tiv thaiv cov tsev ntawm cov qauv hlau.
• Cov qauv hluav taws xob thaiv phab ntsa: Cov qauv pob txha pob txha taub hau raws li iav kab hlau rhuav phab ntsa lossis phab ntsa hlau.
• Choj auxiliary qauv: xws li cov choj pem teb chaw txhawb nqa, kev siv kev tsim kho kev tsim kho ib ntus, thiab lwm yam.

2. Mechanical Raug
• Cov cuab yeej ntsuas: Txhawb cov ncej rau kev lag luam machinery, cov cuab yeej ntau lawm, tshuab cov cuab yeej siv.
• conveying system: conveyor bracket, cov ntaub ntawv khaws cia cov txee.

3. Cov vaj tse thiab cov chaw pej xeem
Femer / GuardNab: Cov qauv tiv thaiv rau kev loj, tshav dav hlau, chaw ntau pob.
• Lub Ncej Teeb Ncej / Kos Npe Phaj: Cov khoom siv hauv paus rau cov teeb pom kev zoo thiab teeb liab teeb liab.

4. Lub zog tshiab thiab siv tshwj xeeb
• Hnub ci txhawb nqa: Cov qauv txhawb nqa ntawm lub photovoltaic zog tiam (nrog tawm tsam kev kho mob corrosion).
• Cov chaw nyob ib ntus: Exhibition sawv, tsim kev tsim kho (raug rau cov qauv kev nyab xeeb ntxiv).

Kev ua tau
JIS G3466 Cov Yeeb Nkab Hlau Raug Xav Tau Ua Raws Li Cov Txheej Txheem, cov kauj ruam tseem ceeb muaj xws li:

1. Npaj raw khoom siv
• Kev xaiv cov hlau steel: carbon steel coil conforming rau JIS G3131 (kub dov cov ntawv hlau qis dua steel hlau) lossis cov qauv zoo sib xws.
• Unciling thiab Levering: Tus Steel Chev yog ib qho kev ntxhov siab hauv kev ntxhov siab thiab kev ntxhov siab sab hauv yog tshem tawm los ntawm tus qib kom ntseeg tau cov ntawv tiaj tus.

2. Moulding txheej txheem
• Cov phaj txias: Lub phaj Steel yog maj Bent mus rau hauv ib lub xwmfab lossis duab plaub raj dawb paug ntawm cov hlua txuas txuas ntxiv mus.
• Cov kev siv hluav taws kub ntau zaus (HFW): Kev nquag siv hluav taws xob ua kom muaj zog tsim kom muaj kev kaw (vuam seams yuav tsum ua kom tau raws li ntawm JIS cov qauv).

3. Ua tiav thiab tom qab kev kho mob
• Sizing thiab ncaj: kho cov qhov tseeb ntawm cov yeeb nkab los ntawm pwm kom tshem tawm txoj kev tsis muaj kev cuam tshuam.
• Txiav: ya pom lossis laser txiav raws li cov neeg siv khoom ntev.
• Nto Kho:
◦ Pickling / Sandblasting: Tshem tawm cov oxide thiab vuam.
◦ Galvanizing / Txheej: txhim kho corrosion tsis kam (xaiv cov txheej txheem, kev xaiv rau JIS h {0}} thiab lwm cov qauv).

4. Kev Soj Ntsuam Zoo
• Cov Khoom Siv Neeg Kho Tshuab: Tshawb Kuaj Tensile Zog (ntau dua lossis sib npaug ntawm 270 MPa), tawm lub zog, elongation, thiab lwm yam.
WELD Kev Soj Ntsuam: eddy kev soj ntsuam tam sim no (ect) lossis kev kuaj ultrasonic (ees) kom ntseeg tau tias tus weld yog pub dawb.
• Qhov seem tsis pub muaj kev ntxhov siab: Tshawb seb qhov seem loj, Phab Ntsa Thickness thiab ncaj ntsib cov kev xav tau ntawm JIS466.

1. Kev tswj cov txheej txheem vuam: kom tsis txhob muaj cov khoom siv embrittlement tshwm sim los ntawm overheating, txuam nrog cov ntaub ntawv vuam thiab cov ntsuas yuav tsum siv.
2. Txias kev tsim kho qhov tseeb: kev hnav khaub ncaws yob yuav tsum tau ntsuas tsis tu ncua los tiv thaiv ntu ntawm kev tawm tsam.
3. Kev tiv thaiv corrosion corrosion: yog tias siv nyob rau hauv ib puag ncig sab nraum zoov lossis siab heev ntawm galvanized txheej los yog lub tsho tiv no ua rau cov txheej txheem tiv thaiv corrosion.

Kev sib piv nrog lwm cov qauv
• Txawv los ntawm J3444 (ncig lub raj): JIS G3466 yog tsim rau square / plaub hau, nrog ntau dua kev qhia thiab muaj kev sib txuas yooj yim.
Cov Txheej Txheem Thoob Ntiaj Teb: Cov qauv zoo sib xws xws li en 10219 (cov yeeb nkab txias tsim hauv Tebchaws Europe) thiab ASTM A500 (cov pa roj carbon (cov pa roj carbon monoxide
