ZhenAn Silicon (Hlau) Hmoov Ntxiv Ntshiab
Nyob rau hauv cov txheej txheem ntau lawm ntawm kev lag luam foundry, ntxiv qhov tsim nyog tus nqi ntawmhlau silicon hmoovtuaj yeem ua si qee yam deoxidation nyhuv. Hlau silicon hmoov tuaj yeem hloov ferrosilicon, txo cov nqi tsim khoom thiab txhim kho qhov zoo ntawm castings. Hlau silicon hmoov reacts nrog oxygen nyob rau hauv cov kua slag theem los yog kua hlau, xav kom tso ib tug loj npaum li cas ntawm combustion kub, vim hais tias cov tsim SiO2 sai sai khiav tawm nyob rau hauv cov ntaub ntawv no, ntxiv dag zog rau kinetic tej yam kev mob ntawm cov tshuaj tiv thaiv. Cov yam ntxwv no tseem ceeb heev rau deoxidation. Cov txheej txheem yuav pab tau.
Ob lub Si thiab C muaj nyob hauv SiC muaj peev xwm raug oxidized. Thaum qhov kub thiab txias yog tib yam, lub peev xwm ntawm ob yog kwv yees li qub. Yog li ntawd, SiC kuj yog ib qho zoo heev deoxidizer tsis yog rau cov cua txias cupolas, tab sis kuj rau cov cua kub cupolas.
Silicon Powder rau Thermal Spray
Cov nyhuv deoxidation ntawm SiC yog nyob rau hauv qhov cub induction. SiSiC thiab CSiC yog txiav txim siab los ntawm cov khoom seem ntxiv thiab nws qhov zoo, xws li ntawm 85% thiab ntau dua 95%. Rau cupolas, nws qhov tseem ceeb yog me me, thiab cov nyhuv deoxidation tuaj yeem tsuas yog qhia hauv cov ntsiab lus dav dav. Cov txheej txheem melting (xws li kev siv cov cua txias, cua thib ob, oxygen enrichment, cua kub, acidity, alkalinity, tsis muaj hauv ob sab phlu) thiab ib ntus kev hloov nyob rau hauv lub melting txheej txheem yuav muaj ib qho tseem ceeb cuam tshuam.
Qhov tseeb,metallic silicon hmoovtuaj yeem siv tsis tau tsuas yog hauv kev lag luam foundry, tab sis kuj nyob rau hauv lwm yam lag luam.
