ASTM A53 Cov Yeeb Nkab Carbon Hlau

Nkag Siab ERW YEEB: Cov Ntsiab Lus thiab Cov Ntsiab Lus Erd cov khoom nplaum lub ntsiab lus thiab dab tsi yog ERW YEEB

ERW, uas sawv rau hluav taws xob tiv thaiv vuam, muab nce rau ib qho tshwj xeeb ntawm cov yeeb nkab steel. Yog li, dab tsi yog erw yeeb nkab? Ib cov yeeb nkab erw, lossis ntau dua cov hluav taws xob tiv thaiv hlauv steel yeeb yaj kiab, ua ke los ntawm thawj cov npoo ua ke siv lub hauv paus ua ke siv hluav taws xob ua ke. Thaum cov chav tsev hluav taws xob tam sim no los ntawm cov npoo ntawm cov hlau sawb, qhov xam tiv thaiv ntawm cov hlau ua kom sov. Qhov kub no yog txaus kom yaj cov npoo, thiab nrog daim ntawv thov ntawm siab, molten txhim kho fuse, tsim kom muaj zog thiab txuas ntxiv weld.

Kev tsim khoom txheej txheem ntawm ERW YEEB

Kev sib yuav ntawm ERW kav yog qhov meticulously orchestrated muaj kab ke ntawm cov kauj ruam. Thaum pib, lub steel sawb yog ua tib zoo uncoiled thiab ncaj. Qhov no tseem ceeb thawj kauj ruam ua kom cov kab txaij muaj qhov chaw tiaj thiab tsis sib xws, tso lub hauv paus rau qhov siab- zoo kawg cov khoom lag luam. Tom qab, nws undergoes ib txheej txheem tu kom huv. Ib qho av, xeb, lossis lwm yam paug uas tuaj yeem yog Mar Weld zoo raug tshem tawm. Cov theem tom ntej muaj feem cuam tshuam nrog kev siv cov kab yob kom meej kom cov kab txaij ua cov sawb mus rau hauv lub tog raj kheej. Thaum lub tog raj kheej tsim, cov npoo tau coj mus rau hauv ze ze. Cov hluav taws xob ces nias tiv thaiv cov npoo, thiab ib qho hluav taws xob tam sim no yog siv. Cov cua sov tsim los ntawm cov kev tawm tsam cov npoo, thiab lub siab los ntawm cov hluav taws xob yuam, ua rau muaj kev muag khoom weld mold. Tshaj tawm - vuam, cov yeeb nkab yuav raug rau cov txiaj ntsig ntxiv xws li kev kho kom zoo nkauj, thiab kho cua sov kom txhim kho nws cov khoom siv cua sov thiab sab ruaj khov.
