Peb daim hlau muab faib ua phaj nruab nrab thiab dov phaj. Cov phaj nruab nrab tsuas yog siv nyob rau hauv submerged arc rhiav, thiab dov phaj yog siv ntau dua.Cov phaj no tsuas yog muab tso rau hauv cov khoom siv raw ntawm cov yeeb nkab steel tom qab kev tshuaj ntsuam xyuas thiab tshem tawm xeb.
Cov qauv siv feem ntau ntawm cov kauj no yog 1620, 1540, 1380, 1290, 1250, 1130 thiab 1020. Lawv yog siv rau kev thauj mus los ntawm cov roj av, roj tsheb, kev thauj mus los ntawm dej vapor, steel qauv, kab sib chaws, machining thiab sib sib zog nqus ua. Kev siv yog dav heev.
Ntxiv mus, peb daim hlau yog muab los ntawm cov loj-paub steel mills xws li Tuam Tshoj Railway thiab Zongheng, thiab qhov zoo yog guaranteed heev. Txais tos hu rau Huayang yog tias koj xav tau ncaj welded steel kav.
Qhov tseem ceeb ntawm cov khoom siv raw rau cov yeeb nkab steel zoo yog qhov tseeb ntawm nws tus kheej. Qhov zoo ntawm cov ntaub ntawv raw yog ncaj qha ntsig txog kev ua haujlwm, kev pabcuam lub neej thiab kev ua haujlwm hauv cov ntawv thov sib txawv ntawm cov kav dej steel. Cov hauv qab no yog piav qhia qhov tseem ceeb ntawm cov khoom siv raw rau cov yeeb nkab steel zoo los ntawm ntau yam:
Ib, Txiav txim siab cov yam ntxwv ntawm cov kav hlau steel
Lub zog thiab toughness: Cov hlau zoo feem ntau muaj lub zog siab thiab tawv, uas yog lub hauv paus rau kev tsim cov kav hlau zoo. Lub zog siab txhais tau hais tias cov yeeb nkab steel tuaj yeem nqa tau ntau dua, thaum lub siab tawv kom ntseeg tau tias cov yeeb nkab steel tsis yooj yim tawg thaum nws raug cuam tshuam los yog siab. Cov cuab yeej no tseem ceeb heev rau kev siv cov yeeb nkab steel hauv kev tsim kho, tshuab, tsheb thiab lwm yam.
Hnav tsis kam thiab corrosion kuj: high-zoo steel feem ntau muaj zoo hnav tsis kam thiab corrosion kuj. Kev hnav tsis kam ua rau cov yeeb nkab steel kom muaj qhov zoo ntawm qhov zoo hauv cov txheej txheem siv mus ntev thiab txo qhov kev ua haujlwm degradation los ntawm kev hnav; Corrosion kuj ua kom ntseeg tau tias cov yeeb nkab steel tseem tuaj yeem ua haujlwm ruaj khov hauv qhov chaw ntub dej thiab corrosive thiab ua kom nws lub neej ua haujlwm ntev.
Weldability: Zoo weldability yog ib qho tseem ceeb yuav tsum tau nyob rau hauv cov txheej txheem ntawm steel yeeb nkab ua thiab siv. Cov hlau zoo feem ntau muaj cov weldability zoo, uas tuaj yeem tuav lub zog thiab nruj ntawm qhov vuam thaum vuam, yog li ua kom muaj kev ua tau zoo thiab kev nyab xeeb ntawm cov yeeb nkab steel.
2, cuam tshuam cov txheej txheem ntawm cov yeeb nkab steel
Kev xaiv cov khoom siv raw: Hauv cov txheej txheem ntawm cov yeeb nkab steel, kev xaiv cov khoom siv raw yog thawj kauj ruam tseem ceeb. Tsuas yog los ntawm kev xaiv cov khoom zoo steel uas ua tau raws li lub teb chaws thiab cov qauv kev lag luam tuaj yeem ua kom ntseeg tau tias kev ua tiav ntawm cov txheej txheem tsim khoom tom ntej thiab qhov kawg ntawm cov khoom siv steel yeeb nkab.
Kev siv thev naus laus zis: nws yooj yim dua los tswj qhov tseeb qhov tseeb thiab qhov chaw zoo ntawm cov hlau zoo thaum ua haujlwm, yog li txhim kho cov khoom lag luam thiab cov khoom sib xws ntawm cov yeeb nkab steel. Tsis tas li ntawd, cov hlau zoo tuaj yeem hloov kho rau ntau yam kev xav tau, xws li kub dov, txias dov, vuam thiab lwm yam.
3, Nws muaj feem xyuam rau kev nyab xeeb thiab kev ntseeg siab ntawm cov kav dej steel
4, Ua tau raws li lub teb chaws thiab cov qauv kev lag luam
Piv txwv li, cov khoom siv raw ntawm cov yeeb nkab steel zoo ua lub luag haujlwm tseem ceeb. Nws tsis tsuas yog txiav txim siab qhov kev ua tau zoo ntawm cov yeeb nkab steel thiab kev ua haujlwm zoo ntawm kev ua cov thev naus laus zis, tab sis kuj tseem cuam tshuam txog kev nyab xeeb thiab kev ntseeg siab ntawm cov yeeb nkab steel thiab seb nws ua tau raws li lub teb chaws thiab cov qauv kev lag luam. Yog li ntawd, thaum xaiv cov kav dej steel, peb yuav tsum tau them sai sai rau qhov zoo thiab qhov chaw ntawm lawv cov khoom siv raw.
