Tsawg Cov Carbon Steel yog dab tsi?

Cov pa roj carbon tsawg yog ib hom hlau uas muaj cov txheej txheem alloying ua los ntawm cov pa roj carbon tsawg. Feem ntau, nws muaj cov pa roj carbon ntsiab lus uas nyob nruab nrab ntawm 0. 05% thiab 0. 30% thiab cov ntsiab lus manganese uas ntog nruab nrab ntawm 0. {{5}} thiab {{6} .. 5%. Tsawg carbon hlau yog ib qho ntawm feem ntau ntawm cov hlau siv rau cov hom phiaj dav dav, hauv ib feem vim tias nws feem ntau pheej yig dua li lwm hom hlau. Thaum cov hlau muaj cov yam ntxwv uas ua haujlwm tau zoo hauv kev tsim ntau yam khoom lag luam, nws yog feem ntau ua rau daim ntawv tiaj tiaj los yog txaij hlau.

Cov khoom ua los ntawm cov hlau tsis tshua muaj kev sib tw nrog cov khoom lag luam uas tuaj yeem tsim cov khoom siv hlau stainless thiab txhuas cov hlau me. Cov pa roj carbon tsawg tuaj yeem siv los tsim ntau cov khoom lag luam tsim khoom - los ntawm cov cuab yeej siv hauv tsev thiab nkoj sab ua kom qis qis carbon hlau xaim thiab daim phiaj hlau. Txij li nws muaj tsawg cov pa roj carbon nyob rau hauv nws, cov hlau yog feem ntau malleable dua li lwm hom hlau. Raws li qhov tshwm sim, nws tuaj yeem muab dov mus rau hauv cov khoom zoo li lub cev tsheb cav.

Cov pa roj carbon ntsiab lus rau cov vaj huam sib luag uas ua los ntawm cov carbon steel hlau feem ntau tsis tshua zoo, feem ntau yuav qis dua 0. 10%. Cov pa roj carbon ntsiab lus rau cov khoom lag luam zoo li dov daim hlau cov txheej txheem, cov ntawv tso tseg, cov thwj cim, lossis cov seem yog siab dua, feem ntau nce mus txog 0. 30%. Cov kav dej yog cov khoom lag luam tsim los ntawm cov pa roj carbon ntau dua. Feem ntau, cov pa roj carbon txhuam me me siv hluav taws xob yog siv rau kev xa cov khoom siv xws li roj thiab roj.

Cov txheej txheem steelmaking zoo li cov qauv deoxidation tuaj yeem cuam tshuam cov yam ntxwv ntawm cov hlau tsis tshua muaj siab. Feem ntau, cov khoom no tau muab piv nrog cov hlau. Cov pa roj carbon qes qis feem ntau muaj qhov muag softer thiab cov khoom tsis muaj zog dua li cov hlau uas muaj cov pa roj carbon ntau dua. Qhov no tuaj yeem ua rau lawv yooj yim dua rau weld.

Lwm hom carbon hlau muaj xws li nruab nrab, siab, thiab ultrahigh carbon hlau tub ntxhais. Nruab nrab cov pa roj carbon steel ib txwm muaj cov ntsiab lus carbon ntau ntawm 0. 30 thiab 0. 60% thiab cov ntsiab lus manganese poob ntawm 0. 60 thiab 1. {{7} }%. Nws nquag siv rau kev ua cov khoom xws li axles, gears, shafts, thiab rail systems. Feem ntau siv los ua cov xov hluav taws xob ultra-lub zog lossis cov khoom siv rau lub caij nplooj ntoo hlav, cov pa roj carbon steel siab feem ntau muaj cov pa roj carbon muaj nyob ntawm 0. 60 thiab 1. } rau 0. 90%. Ultrahigh carbon steel, uas tuaj yeem siv rau kev tsim cov khoom zoo li riam, yog cov thermomechanically ua tiav thiab feem ntau muaj cov pa roj carbon ntau ntawm 1. 25 rau 2 0%.
