(2) Fesi muaj qhov loj me me, tsis muaj hmoov zoo, thiab cov nyhuv inoculation ruaj khov;
(3) Cov nyhuv inoculation ntawm ferrosilicon hais yog muaj zog dua li ntawm cov ferrosilicon zoo tib yam, thiab nyiam ua slag kuj me me;
(4) Txhim kho pwm lub neej thiab txo qhov tsis xws luag;
(5) Txo cov pinholes, txhim kho qhov zoo ntawm cov kav dej cam khwb cia, thiab nce tus nqi ntawm kev tshuaj xyuas ib zaug;
(6) Tshem tawm microshrinkage porosity thiab txhim kho kev ua haujlwm casting.
Ferrosilicon feem ntau muaj 70% mus rau 75% silicon, uas muab ferrosilicon zoo silicide zog.
Ferrosilicon muaj qis hysteresis poob, uas txhais tau hais tias nws tuaj yeem txo qis zog hauv AC electromagnetic teb.
Cov khoom siv silicon hauv ferrosilicon muaj peev xwm deoxidation zoo thiab desulfurization.
