ERW Ntau Lawm Txhim Kho

Qhov zoo ntawm cov khoom siv raw siv hauv ERW ntau lawm tau txhim kho tau zoo. Tsawg-carbon, tsawg-phosphorus, qis-sulfur steel qhov chaw tsim, microalloying; converter smelting, ladle refining, nqus degassing, nruam casting thiab lwm yam tshiab technologies nyob rau hauv cov txheej txheem smelting. Kev tswj cov dov thiab tswj cov cua txias yog siv rau hauv cov txheej txheem dov Lub tshuab tau zoo heev rau qhov zoo li qhov loj me, zoo li lub cev thiab cov khoom siv tshuaj lom neeg ntawm cov kub dov zeb. Rolled steel strips rau loj thiab nruab nrab-qhov loj me ERW steel kav. Cov raj xa dej uas tsim los ntawm Baosteel Co., Ltd., uas sawv cev rau qib siab tshaj plaws ntawm cov kub-kuav los tiag steel sawb nyob rau hauv Tuam Tshoj, tau mus txog qhov yuav tsum tau ntawm API 5L tus qauv ntawm American Petroleum Institute thiab yog nyob rau hauv lub thoob ntiaj teb ua theem.
