1. Hauv kev siv desulfurization ntawm high-carbon ferrochrome hmoov yuav tsum tau nce qib hauv kev sib tsoo ntawm silicon, carbon ratio, vim hais tias ntawm lub txhuas aluminium hauv silicon, carbon muaj pes tsawg leeg ntawm aluminium alloy sulfur cov ntsiab lus muaj qhov cuam tshuam loj.
2. Tom qab desulfurization ntawm lub siab carbon carbon ferrochrome hmoov, cov hmoov tshauv cov roj teeb tsim yuav tsum tau kho kom raug. Thaum cov hmoov av thee magnesium oxide thiab calcium hydroxide tsis txaus, cov hmoov kua tsim nyog yuav tsum tau muab ntxiv.
3. Txhawm rau txhim kho kev tswj qhov kub thiab txias tuaj yeem txhim kho kev siv ua haujlwm ntawm desulfurization ntawm cov pa roj carbon ferrochrome siab, feem ntau yuav tsum yog cov haujlwm tswj kev kub thaum txog 1650 ~ 1700 ℃ zoo li.
