Dab tsi ua rau cov ntsiab lus qis ntawm Ferrosilicon?

Kev siv coke ua tus neeg sawv cev txo qis rau smelt ferrosilicon, ua kom cov pa roj carbon self-roasting electrodes yooj yim dua, siv cov coke cib los tsim cov hlau qhov ncauj thiab ntws hlau zawj, qee zaum siv cov graphite hmoov coated ingot pwm, kev siv cov qauv carbon. nplawm los sau cov qauv ua kua, thiab lwm yam hauv luv luv, smelting ferrosilicon los ntawm lub cub tawg mus rau cov tshuaj tiv thaiv hlau, cov txheej txheem pouring, lub sij hawm rau kev sib cuag nrog carbon yog obviously ntau.

Txawm li cas los xij, cov ntsiab lus carbon ntawm ferrosilicon tsawg dua {{0}}.1 feem pua, feem ntau 0.05-0.07 feem pua ​​, yog vim li cas? Qhov siab dua cov ntsiab lus ntawm silicon ntawm ferrosilicon, qhov qis dua cov ntsiab lus ntawm ferrosilicon. Raws li cov ntaub ntawv, cov ntsiab lus ntawm silicon ntawm ferrosilicon yog kwv yees li 30 feem pua, thiab feem ntau ntawm cov pa roj carbon nyob rau hauv ferrosilicon muaj nyob rau hauv lub xeev ntawm silicon carbide (silicon carbide). Silicon carbide yog yooj yim oxidized thiab txo los ntawm silicon dioxide los yog silicon oxide nyob rau hauv crucible. Silicon carbide nyob rau hauv ferrosilicon, tshwj xeeb tshaj yog thaum kub tsis tshua muaj, nws solubility me me, yooj yim rau precipitate thiab ntab. Yog li ntawd, cov residual silicon carbide nyob rau hauv ferrosilicon yog tsawg heev, thiab yog li ntawd cov pa roj carbon ntsiab lus ntawm ferrosilicon yog tsawg heev.
