Cov qib steel sib txawv cuam tshuam li cas?
Kev xaiv ntawm qib steel ncaj qha cuam tshuam li cas kev tsheb ciav hlau ASCE 60 ua haujlwm dhau sijhawm. Nws tsis yog hais txog lub zog xwb. Nws yog hais txog yuav ua li cas lub tsheb ciav hlau tuav hnav, qaug zog, thiab cuam tshuam.
Cov ntsiab lus carbon ntau dua ua rau cov tawv tawv. Qhov no txhim kho kev hnav tsis kam ntawm lub taub hau rail. Txawm li cas los xij, cov hardness ntau dhau tuaj yeem txo qhov tawv thiab ua rau muaj kev pheej hmoo ntawm kev tawg.
Alloying ntsiab zoo li manganese txhim kho lub zog thiab qaug zog tiv thaiv. Qhov no yog qhov tseem ceeb hauv cov ntawv thov uas nquag thauj khoom mus.
Rau cov neeg yuav khoom, lub hom phiaj tsis yog xaiv cov khoom siv "nyuaj tshaj", tab sis cov khoom tsim nyog tshaj plaws rau kev ua haujlwm tiag tiag.
Yuav Ua Li Cas Xaiv Cov Qib Hlau Zoo rau Koj Qhov Haujlwm?
Thaum xaiv ASCE 60 txoj kev tsheb ciav hlau, cov neeg yuav khoom yuav tsum pib nrog cov ntawv thov. Load theem, tsheb zaus, thiab ib puag ncig txhua yam cuam tshuam cov khoom xaiv.
- Rau kev siv lub teeb, cov qauv carbon steel xws li ASTM A1 feem ntau yog txaus. Nws muab cov nqi qis dua thiab kev ua haujlwm txaus.
- Rau qhov xav tau ntau dua, xws li kev thauj khoom ntau zaus lossis kev ntxhov siab ntau dua, qib zoo li U71Mn muab kev hnav zoo dua thiab kev pab lub neej ntev dua.
- Yog tias txoj kev tsheb ciav hlau siv nyob rau hauv ib puag ncig hnyav, xws li cov chaw nres nkoj lossis hnyav - txoj haujlwm kev tsheb ciav hlau, xaiv qhov siab dua - cov khoom ua tau zoo tuaj yeem txo qhov kev saib xyuas thiab hloov zaus.
Xaiv cov khoom tsim nyog yuav pab kom tsis txhob muaj kev ua haujlwm tsis zoo thiab tsis tsim nyog.
