Cov hlau kub dov (HRCoil) yog ib hom hlau uas tsim los ntawm cov txheej txheem dov kub. Thaum cov hlau carbon yog ib lo lus dav dav siv los piav qhia txog hom hlau uas muaj cov ntsiab lus carbon tsawg dua 1.2%, cov khoom sib xyaw tshwj xeeb ntawm cov hlau kub dov sib txawv nyob ntawm nws daim ntawv thov. Hauv qhov kev nkag siab no, cov hlau kub dov tsis tas li muajcov hlau carbon.

Cov Txheej Txheem Kub Dov

Kev dov kub yog ib txoj kev ua cov hlau uas cov khoom siv raug cua sov rau qhov kub siab thiab tom qab ntawd dov rau hauv cov ntawv lossis cov kauj. Cov txheej txheem no tso cai rau kev tswj hwm qhov microstructure thiab cov khoom siv kho tshuab ntawm cov khoom siv ntau dua li kev dov txias. Cov kauj dov kub feem ntau yog siv rau ntau yam kev siv, suav nrog kev tsim kho, kev thauj mus los, thiab kev tsim khoom.

Cov Hlau Carbon

Cov hlau carbon yog ib hom hlau uas muaj cov pa roj carbon ua nws cov khoom siv tseem ceeb. Cov pa roj carbon uas muaj nyob hauv cov hlau carbon tuaj yeem sib txawv ntau, xws li cov hlau qis-carbon nrog cov ntsiab lus carbon tsawg dua 0.2% mus rau cov hlau siab-carbon nrog cov ntsiab lus carbon ntau dua 1%. Cov hlau carbon muaj ntau yam khoom siv kho tshuab thiab tuaj yeem siv rau ntau yam kev siv, suav nrog cov khoom siv hauv tsev, cov cuab yeej, thiab cov riam.

Kev Txheeb Xyuas

Cov hlau kub dov thiab cov hlau carbon yog ob qho chaw sib cais nrog cov yam ntxwv thiab kev siv tshwj xeeb. Cov hlau kub dov yog hais txog ib hom hlau tsim los ntawm cov txheej txheem dov kub thiab feem ntau yog siv rau hauv kev tsim kho, kev thauj mus los, thiab kev tsim khoom. Cov hlau carbon, ntawm qhov tod tes, yog hais txog ib hom hlau uas muaj cov pa roj carbon ua nws cov khoom siv tseem ceeb thiab muaj ntau yam khoom siv kho tshuab uas ua rau nws haum rau ntau yam kev siv.
