Cov lus qhia luv luv:

Silicon calcium cored hlau yog cov khoom siv ferroalloy ua los ntawm kev sib tsoo silicon calcium rau hauv cov hmoov ua cov khoom tseem ceeb thiab muab tso rau hauv cov ntawv hlau.

Cov xov kab xaim yog muab tso rau hauv cov hlau molten lossis molten steel ntawm qhov tob tob zoo tshaj plaws los ntawm cov khoom siv hlau, kom cov hlau cored yuav zoo siab thiab silicon-calcium metallurgical cov khoom siv tuaj yeem ua lub luag haujlwm zoo dua.

Nta thiab siv:

* Ua kom tsis muaj hlau molten, hloov cov duab ntawm cov lus sib dhos, deoxidize, desulfurize, degassing, txhim kho qhov zoo ntawm molten steel, txhim kho lub xeev casting.

* Nyob rau hauv tus txheej txheem ntawm kev rov ua kom zoo dua, cov txiaj ntsig ntawm cov ntsiab lus tuaj yeem nce ntxiv, lub sijhawm smelting tuaj yeem ua kom luv, qhov muaj pes tsawg leeg tuaj yeem tswj tau kom raug, thiab tus nqi ntawm steelmaking tuaj yeem txo.

* Alloying ntau yam, siab zoo, yog qhov zoo rau kev nqus ntawm cov ntsiab lus tshwj xeeb.
