SiC hmoov

Silicon Carbide (SiC)

Silicon Carbide siv hauv steelmaking sivqis-qib SiC. Nws ua lub luag haujlwm tseem ceeb hauv kev lag luam metallurgical.

Nws ua raws li qhov ua tau zoocomposite deoxidizer, muaj peev xwm ntawm ib txhij deoxidizing, recarburizing, silicifying, thiab txawm pab kho qhov kub thiab txias. Tam sim no, nws tau dav siv los hloov lossis hloov qee cov khoom siv kim kim xws li ferrosilicon thiab recarburizers, yog li txo cov nqi tsim steel.

Core Functions thiab Mechanism

Thaum SiC ntxiv rau cov hlau molten, nws dhau los ua tshuaj lom neeg. Thawj qhov kev sib npaug yog:

SiC + FeO → Si + Fe + CO↑

Cov txiaj ntsig tseem ceeb ntawm cov tshuaj tiv thaiv no suav nrog:

Deep Deoxidation:Cov tshuaj tiv thaiv sai sai txo cov ntsiab lus oxygen hauv cov hlau molten. Lub generated CO roj kuj nce, stirring lub molten da dej thiab pab tshem tawm impurities, yog li purifying cov hlau.

Siv Recarburization thiab Silicification:Cov silicon (Si) thiab carbon (C) tso tawm los ntawm cov tshuaj tiv thaiv yaj rau hauv cov hlau molten, zoo ntxiv ob qho tib si ib txhij.

Txhim kho steel huv huv:SiC muaj tsawg dua impurities (xws li sulfur thiab nitrogen) dua li cov khoom siv rov ua dua tshiab (piv txwv li, roj av coke), uas muaj txiaj ntsig zoo rau kev txhim kho cov hlau kawg.

Auxiliary Temperature Adjustment:Cov tshuaj tiv thaiv deoxidation yog exothermic, uas pab txhawb qhov kub ntawm cov hlau molten. Nws tuaj yeem siv los ua cov khoom cua sov thaum cov ntsiab lus carbon siab tab sis qhov kub thiab txias tsis tshua muaj.
