1. ** Dab tsi yog cov khoom siv nyoos rau kev ua cov kav hlau steel? **
Cov ntaub ntawv raw thawj yog ** hlau ore, thee (hloov pauv (hloov dua siab tshiab rau Coke), thiab limestone **. Siv cov qauv hloov scrap kuj tseem yog cov khoom siv raw loj.
2. ** Dab tsi yog cov khoom siv ntawm cov yeeb nkab steel? **
Cov kav dej hlau yog feem ntau ua los ntawm ** Hlau **, ib qho alloy tsim feem ntau ntawm ** (fiCon (NI), lossis Molybdenum (mo) rau cov khoom tshwj xeeb.
3. ** Cov ntaub ntawv raw rau hlau? **
Cov ntaub ntawv tseem ceeb yog:
- ** Cov ore hlau ** (qhov chaw ntawm cov hlau)
- ** COKING CoAL ** (hloov dua siab tshiab rau Coke rau roj thiab txo tus neeg sawv cev)
- ** Limestone ** (flux kom tshem tawm impurities)
- ** Dua SCRAP hlau ** (feem ntau siv hauv hluav taws xob arc rauv).
4. ** Dab tsi yog cov khoom siv hlau nplaum tshaj plaws? **
** Carbon Steel ** yog cov khoom siv feem ntau, tshwj xeeb ** me-carbon (me) hlau ** (piv txwv li, ASTM A53, API 5L gr). Nws muaj lub zog zoo, Weldability, thiab tus nqi-ua hauj lwm zoo rau cov ntawv thov uas dav dav.
5. ** Yuav ua li cas 3 qib ntawm cov yeeb nkab steel? **
Peb dav siv qib yog:
- ** ASTM A53 **: Cov qauv rau welded \/ seamless cov pa roj carbon steel hlau (kev pabcuam dav dav).
- ** ASTM A106 **: Txheem rau Seamless cov pa roj carbon hlau hlau (qhov kev pab kub siab).
- ** API 5L **: Txuj ci rau seamless \/ Welded Steel Kab Kav (Roj \/ Roj \/ Roj \/ Roj \/ Roj \/ Gr B, X42, X65).
