Hom Hlau Zoo Li Cas Rau Smelting Ferrosilicon

Hlau nyob rau hauv ferrosilicon los ntawm steel scraps nyob rau hauv tus nqi. Raws li cov kev xav tau zoo ntawm ferrosilicon, tsuas yog cov pa roj carbon monoxide pov tseg raug tso cai siv rau hauv smelting, thiab khib nyiab hlau xws li stainless hlau nrog cov ntsiab lus chromium, siab manganese hlau nrog cov ntsiab lus manganese siab, thiab lwm yam, siv tsis tau. Yog li ntawd, kev siv cov khib nyiab hlau rau smelt ferrosilicon yuav ua rau cov khoom pov tseg. Cam khwb cia hlau sawdust kuj tsis tuaj yeem siv vim nws cov ntsiab lus phosphorus siab. Cov khib nyiab uas tsis yog-ferrous hlau, xws li tooj liab thiab txhuas, tsis tuaj yeem siv los ua ferrosilicon. Yog li ntawd, txhawm rau kom ntseeg tau qhov zoo ntawm ferrosilicon, tsuas yog cov khib nyiab steel ua los ntawm cov pa roj carbon zoo tib yam tau tso cai siv rau hauv smelting.

Cov khib nyiab hnyav hlau tsis tuaj yeem siv tau, vim nws muaj ntau cov impurities thiab cov ntsiab lus hlau tsis yooj yim rau kev tswj xyuas thaum smelting. Nyob rau tib lub sijhawm, cov khib nyiab hnyav hnyav hlau tsis muaj zog thiab cov hmoov ntau, uas cuam tshuam rau huab cua permeability ntawm cov khoom siv thaum ntxiv rau hauv lub cub tawg. Yog li ntawd, nws yog ib qho tsim nyog uas cov ntsiab lus hlau hauv cov khoom siv hlau siv ntau dua 95% thiab qhov chaw huv si, tsis muaj qhov pom tseeb.

Qhov ntev ntawm cov hlau scraps yuav tsum tsis txhob ntev dhau los tiv thaiv kev sib xyaw tsis sib xws thiab txhaws ntawm cov yeeb nkab pub. Hlau trimmings uas ntev dhau lawm kuj yuav ua rau cov nqi thauj khoom tsis sib xws thiab cuam tshuam rau kev thauj khoom peb-theem tsis sib npaug. Vim li no, nws raug nquahu kom muab qhov ntev ntawm cov khoom siv hlau yuav tsum tsis pub tshaj 100 mm.
