High Carbon Ferrosilicon Rau Foundry Kev Lag Luam
Cov pa roj carbon ntau ferrosilicon feem ntau yog ntim rau hauv cov thawv hnyav hnyav lossis cov hnab ntim loj rau kev thauj mus los thiab khaws cia. Cov nruas feem ntau yog hlua nrog lub hnab yas kom tsis txhob ya raws los ntawm kev cuam tshuam cov khoom zoo. Qhov hnyav ntawm txhua lub nruas tuaj yeem muaj li ntawm 200 kg txog 1000 kg, nyob ntawm qhov loj ntawm lub nruas thiab cov kev xav tau ntawm cov neeg siv khoom.

Kev piav qhia
High carbon ferrosilicon yog ib hom ferrosilicon alloy uas siv dav hauv kev lag luam foundry rau kev tsim hlau thiab hlau castings. Nws yog tsim los ntawm hlau, silicon, thiab carbon, nrog cov ntsiab lus carbon feem ntau yog li ntawm 2 mus rau 10 feem pua. Cov ntsiab lus carbon siab ntawm cov hlau no ua rau nws yog qhov zoo tshaj plaws ntawm cov pa roj carbon rau steel ntau lawm, raws li nws tso cai rau kev tswj xyuas cov ntsiab lus carbon ntawm cov khoom kawg.
Nyob rau hauv cov ntawv thov foundry, siab carbon ferrosilicon yog siv los ua deoxidizer thiab alloying tus neeg sawv cev. Thaum ntxiv rau molten hlau los yog hlau, nws reacts nrog oxygen los tsim silicon dioxide (SiO2) thiab carbon monoxide (CO), uas yog ob qho tib si gases uas yooj yim tshem tawm ntawm lub yaj. Qhov no yuav pab kom huv si cov hlau thiab tiv thaiv kev tsim ntawm qhov tsis xws luag xws li porosity thiab slag inclusions.
Tsis tas li ntawd, siab carbon ferrosilicon kuj tseem siv los ua tus neeg sawv cev alloying los muab cov khoom tsim nyog rau cov khoom kawg, xws li nce hardness, lub zog, thiab hnav tsis kam. Nws yog feem ntau siv rau hauv kev tsim cov hlau cam khwb cia, uas yog ntau yam khoom siv uas siv ntau yam kev siv, suav nrog cov khoom siv tsheb, cov kav dej thiab fittings, thiab cov khoom siv tshuab.
Specification
Silicon (Si): 70-80 feem pua min

Loj: 0-10mm, 10-50mm, los yog raws li cov neeg siv khoom xav tau.
Nta:
Feem ntau muaj nyob ib ncig ntawm 70-80 feem pua silicon thiab 4-8 feem pua carbon, nrog rau cov seem uas yog tsim los ntawm lwm yam xws li sulfur, phosphorus, thiab txhuas.
Grey los yog nyiaj nyob rau hauv cov xim, nrog ib tug metallic luster.
Siab melting point, feem ntau nyob ib ncig ntawm 1,200 txog 1,400 degrees Celsius.
Ua raws li tus neeg sawv cev deoxidizing thiab txhim kho cov khoom siv ntawm cov hlau cam khwb cia thiab hlau.
Qhov zoo:
Txhim kho cov cuab yeej cuab tam ntawm cam khwb cia hlau thiab hlau, xws li hardness, lub zog, thiab toughness.
Ua raws li tus neeg sawv cev deoxidizing, pab tshem tawm cov pa oxygen thiab lwm yam impurities hauv molten hlau.
Ua kom lub fluidity thiab casting muaj peev xwm ntawm molten hlau.
Nqi-zoo piv rau lwm yam alloying ntsiab xws li nickel, chromium, thiab molybdenum.
