1. Lub thickness ntawm lubsilicon ferroingot yuav tsum tsis txhob tuab heev kom txo tau cov degree ntawm segregation ntawm silicon cov ntsiab lus nyob rau hauv lub fe silicon. nruj me ntsis tswj cov ntsiab lus ntawm silicon ntawm ferrosilicon, tsis tsawg dhau.

2. Tswj cov txhuas, phosphorus thiab calcium cov ntsiab lus ntawm carbon ferro silicon siab. Rau lub hom phiaj no, cov khoom siv raw zoo dua yuav tsum tau siv, tshwj xeeb tshaj yog cov hmoov tshauv coke tsis tuaj yeem siv los txo cov ntsiab lus txhuas thiab phosphorus. Txhawm rau txo cov calcium cov ntsiab lus ntawm ferrosilicon, nws yuav tsum raug txo kom tsawg thaum smelting. Ntxiv txiv qaub.

3. Ceev cov cua txias ntawm fe si kua, tiv thaiv cov hlau ingot segregation, thiab txo cov tsub zuj zuj ntawm cov teeb meem.
4. Txo cov ntsiab lus ntawm kev puas tsuaj impurities P, ca, thiab lwm yam.
