Kev nkag siab txog qib ntawm cov saw hlau yog qhov tseem ceeb rau kev xaiv cov saw hlau zoo rau kev lag luam, kev nqa khoom, lossis kev nyab xeeb. Muaj ntau hom saw hlau sib txawv hauv khw, peb yuav paub li cas yog tias peb siv qib ntawm cov saw hlau zoo rau peb cov haujlwm? Kauj ruam thawj zaug yog kev paub txog qib saw hlau, cov khoom tiav ntawm cov saw hlau thiab lawv txhais li cas.
Cov Qib Chain Yog Dab Tsi?
Cov qib saw hlau yog ib txoj hauv kev los faib cov saw hlau ua los ntawm cov hlau sib xyaw raws li lawv lub zog tensile thiab qhov txwv tsis pub ua haujlwm (WLL). Qib siab dua, cov saw hlau yuav muaj zog thiab tawv dua.
| Qib | Khoom siv | Lub zog tensile (psi) | Kev Siv Feem Ntau |
| Qib 30 | Cov pov thawj kauj (carbon) | ~30,000 | Kev ua haujlwm yooj yim: khi, thaiv kev |
| Qib 43 | Kev Ntsuas Siab (carbon) | ~43,000 | Kev khi khoom, kev rub, kev sau ntawv |
| Qib 70 | Kev Thauj Mus Los (hlau) | ~70,000 | Cov saw hlau thauj khoom, cov khoom siv khi tsheb thauj khoom |
| Qib 80 | Cov hlau sib xyaw | ~80,000 | Kev nqa saw, cov saw ntoo, rigging |
| Qib 100 | Cov hlau alloy zoo tshaj plaws | ~100,000 | Kev nqa hnyav, kev sib txuas, kev nqa saum toj kawg nkaus |
| Qib 120 | Cov hlau alloy txhim kho | ~120,000 | Kev tshwj xeeb hnyav lifting |
Cov Lus Tseem Ceeb Yuav Tsum Paub:
1. Kev Txwv Kev Thauj Khoom Ua Haujlwm (WLL):Qhov hnyav tshaj plaws uas ib txoj saw hlau tuaj yeem nqa tau zoo.
2. Lub zog tensile:Lub zog siab tshaj plaws ntawm cov saw hlau tuaj yeem tiv taus ua ntej tawg.
3. Kev Ntsuas Pov Thawj:Ib qho kev sim ntawm qhov kev thauj khoom tshwj xeeb (feem ntau yog 2x WLL) kom paub tseeb tias tsis muaj qhov tsis zoo.
Cov Saw Tiav:
Nov yog cov ntsiab lus luv luv ntawm lawv lub ntsiab lus:
1. Xim tus kheej:tsis muaj qhov tiav lossis txheej
2. Cov oxide dub:Cov oxide dub lossis blackening yog ib txheej hloov pauv rau cov khoom siv ferrous, siv los ntxiv qhov tiv taus corrosion me ntsis, rau qhov tsos, thiab kom txo qhov kev cuam tshuam ntawm lub teeb.
3. Hluav taws xob galvanized:electroplating los siv zinc rau ntawm qhov chaw, muab tso rau hauv cov kua ntsev zinc, thiab hluav taws xob tso cov zinc du, ci, nyias, sib xws.
4. Kub dip galvanized:Nws cuam tshuam nrog kev muab cov hlau tso rau hauv cov zinc uas yaj ntawm qhov kub li ntawm 450 ° C, Cov zinc cuam tshuam nrog cov hlau los tsim cov txheej zinc-hlau sib xyaw tuab dua, Muab kev tiv thaiv xeb zoo dua rau lub sijhawm ntev, tshwj xeeb tshaj yog sab nraum zoov.
5. Hmoov txheej: Kev txheej hmoov yog ib hom txheej uas siv ua hmoov qhuav thiab ntws dawb.Cov txheej txheem hmoov tuaj yeem tsim cov txheej txheem tuab dua li cov txheej txheem kua ib txwm yam tsis muaj kev khiav lossis sagging.
Lus Cim:Tsuas yog Qib 80 thiab siab dua thiaj li tau txais kev pom zoo rau kev nqa saum toj raws li OSHA thiab ASME cov qauv.
Xaiv Txoj Cai Saw:
1.Txiav txim siab qhov hnyav:Paub qhov hnyav thiab qhov kev nyab xeeb.
2. Ib puag ncig:Corrosive, high-temperature, thiab lwm yam.
3. Siv:Lifting, rub, khi, thiab lwm yam.
4. Cov Cai:OSHA, DOT, lossis lwm yam kev ua raws li cov cai.
