Cored Hlau Rau Hlau Ua

Ferroalloy cored hlau yog ib hom steelmaking cored hlau, feem ntau suav nrog ferrosilicon, ferromanganese, ferrochrome thiab lwm yam. Ntxiv cov ntsiab lus no hauv cov txheej txheem steelmaking tuaj yeem txhim kho lub zog, hardness thiab hnav tsis kam ntawm steel. Ferroalloy cored hlau reacts nrog oxygen, sulfur thiab lwm yam hauv cov hlau kom ua tiav lub hom phiaj ntawm deoxidation thiab desulfurization.

Calcium silicate core hlau yog ib hom steelmaking core hlau nrog lub peev xwm ntawm desulfurization thiab deoxidation. Calcium silicate caij tuaj yeem hnov ​​​​mob nrog cov pa oxygen, sulfur thiab lwm yam hauv cov hlau los tsim cov tebchaw ruaj khov, yog li ua tiav cov txiaj ntsig ntawm desulfurization thiab deoxidation. Tsis tas li ntawd, calcium silica core hlau tseem muaj lub luag haujlwm ntawm cov nplej ua kom zoo dua qub, txhim kho cov plasticity thiab toughness ntawm cov hlau.

Aluminium thiab magnesium core hlau yog ib hom tshiab ntawm cov tub ntxhais hlau hlau, feem ntau yog siv los txhim kho corrosion kuj ntawm steel thiab vuam kev ua tau zoo. Aluminium thiab magnesium tuaj yeem hnov ​​​​mob nrog cov pa oxygen hauv cov dej steel los tsim cov txhuas oxide thiab magnesium oxide zaj duab xis, zoo tiv thaiv cov pa yaig ntawm cov hlau. Nyob rau tib lub sijhawm, aluminium thiab magnesium core hlau kuj tseem tuaj yeem kho cov nplej, txhim kho lub zog thiab lub zog ntawm cov hlau.
