Cov lus qhia luv luv:

Silicon thiab calcium cored hlau yog cov khoom siv sib xyaw ua ke ntawm silicon thiab calcium alloy tawg rau hauv qee qhov loj me thiab tom qab ntawd dov nrog txias dov tsawg carbon hlau sawb. Nws yog tsuas yog siv rau kev ua steel thiab casting.

Nta thiab siv:

* Nws muaj txiaj ntsig los kho thiab tswj cov ntsiab lus ntawm cov pa yooj yim thiab cov ntsiab lus, zoo heev kom cov alloy tso tawm, txo tus nqi ntawm kev ua kom cov steelmaking, luv rau lub sijhawm sib tsoo thiab ua tib zoo tswj qhov muaj pes tsawg leeg.

* Nws tuaj yeem ntxuav molten steel thiab ib nrab hloov cov khoom thiab cov ntaub ntawv ntawm kev koom tes, txhim kho qhov zoo ntawm molten steel thiab txhim kho lub xeev casting.

* Cov xaim xaim hluav taws xob tau muab faib ua ob hom: kev kos duab sab hauv thiab sab nraud. Cov cuab yeej siv cuab yeej xav tau rau xaim hlau yog yooj yim thiab txhim khu kev qha.
