Cov pa roj carbon phaj
| Yam khoom | Carbon steel phaj/ ntawv |
| Taw qhia | Feem ntau yog hais txog cov hlau uas nws cov pa roj carbon feem tsawg dua 2.11% thiab tsis muaj tshwj xeeb ntxiv cov khoom sib xyaw. Qee zaum hu ua cov pa roj carbon dawb lossis cov pa roj carbon. Cov pa roj carbon tseem hu ua carbon steel, uas hais txog cov hlau-carbon hlau nrog cov ntsiab lus carbon ntawm Wc tsawg dua 2.11%. Cov pa roj carbon feem ntau muaj me me ntawm silicon, manganese, sulfur, thiab phosphorus ntxiv rau carbon. Nws yog cov hlau tiaj tus uas tau nchuav nrog cov hlau yaj thiab nias tom qab txias. Nws yog tiaj thiab cov duab plaub, thiab tuaj yeem ncaj ncaj dov lossis txiav los ntawm cov hlau dav. Cov pa roj carbon tuaj yeem faib ua peb hom: carbon txheej txheem hlau, cov cuab yeej siv cov hlau thiab cov txiav cov qauv hlau dawb raws li nws lub hom phiaj. Cov txheej txheem carbon hlau tau muab faib ntxiv rau hauv kev tsim vaj tsev hlau thiab tshuab tsim cov hlau; Raws li txoj kev smelting, nws tuaj yeem muab faib ua qhib hearth steel thiab hloov steel; Raws li txoj hauv kev deoxidation, nws tuaj yeem muab faib ua cov hlau kub (F), tua cov hlau (Z), steel ib nrab tua (b) thiab tshwj xeeb tua hlau (TZ); Feem ntau, ntau dua cov ntsiab lus ntawm cov pa roj carbon, ntau dua qhov nyuaj thiab muaj zog dua, tab sis qis dua cov yas. |
