Ferro phosphorus (Cov mis nyuj noj: Fe₃p, feem ntau cov tsiaj ntawv hais tias raws li hlau (fe) thiab phosphorus cov ntsiab lus feem ntau yog kwv yees li 20% mus rau 35%. Tsis zoo li cov phosphorus ntshiab (muaj kuab lom thiab volatile), ferrophosphorus yog qhov ruaj khov, thiab siv tau yooj yim}}

FEP Almoy yog tsim los ntawm pyrometallurgical smelting, siv phosphorus ore (apatite lossis phosphorite), hlau ore, thiab coe ua cov ntaub ntawv raw. Tus txheej txheem muaj ob txoj kev loj:

Fais arc rauve (EAF) txoj kev:Siab - kub smelting (1500-1600℃phosphorus hlau (p ntau dua li {}} haum rau precision alloys.
Moj Tej Siab Rauv Txoj Kev:Co - smelting nrog ironmaking, yi-}- qhov zoo tagnrho rau cov txheej txheem steel.

Ob qho txheej txheem hloov pauv dag phosphorus phosphorus rau hauv ruaj khov fe₃p, tshem tawm cov phom sij thiab ua kom cov hlau phosphorus tso tawm hauv molten hlau.

Daim ntawv tseem ceeb: phosphorus cov ntsiab lus saws txiav txim ncaj qha {{heb} dua p cov txheej txheem kev coj tsis kam tab sis tej zaum yuav nce siab dua? BOIN P Cov qib sib npaug lub zog thiab ductility rau cov qauv hlau qauv.

Cov kev siv tseem ceeb ntawm ferro phosphorus

Ferro Phosphorus lub peev xwm los tswj cov ntsiab lus phosphorus thiab txhim kho cov khoom siv hlau ua rau nws tsis tseem ceeb thoob plaws kev lag luam tseem ceeb:

Steelmaking: Deagidation & Alloy ntxiv dag zog

Deagidation AuXilation:

Hauv qhov qis -} alloy txheej txheem steel, ntxiv 0.2-0.5%} pos oxygen ferro piv rau (O) los ntawm 50-70 ppm rau tsawg dua los yog sib npaug rau 25 pm. Phosphorus reacts nrog o los ua p₂o₅ ruaj khov, uas ua ke nrog sio₂ los ua tus {{}}}}} tso tawm), txo cov olide inclusions los ntawm 30%.

Alloy ntxiv dag zog:

Rau siab - lub zog hlau (piv txwv li, tswj tau lub zog ntawm ferrophorus)

Weathering Hlau:

Ntxiv 0.06-0.12% p ntawm nruab nrab {2} Piv rau cov qauv steel {}}}}} siv hauv cov choj, kev tsheb nqaj hlau, thiab sab nraum zoov cov qauv.

Casting: FLUCTIONY & KEV POJ OTWORKENTION

Grey Hlau casting:

Nruab Nrab - phosphorus FEP (25-30% P) ntxiv rau ntawm 0.3-20%} Cov tsev twj tso kua mis (piv txwv li lub cev tso kua mis) nrog qhov tsawg kawg nkaus shrinkage tsis xws luag. Nws kuj tseem nce saum npoo hardness los ntawm 20-25%, txhim kho kev coj ua rau cov tshuab kho tshuab.

Zas Iron Haum:

Hauv cov hlau crankshafts, trace phosphorus (0.02-0.04% ntawm kev tsis txaus siab "

Tshwj xeeb alloys: hnav & hluav taws kub tiv taus

Hnav - istant alloys:

Siab - phosphorus FEP (30-35% p) yog qhov tseem ceeb ntawm fe {p} p} p alloys (siv hauv cov ntaub pua plag (excavator thoob). Ntxiv 8-12% P cov fa hard fe₃p theem (hardness ntau dua los yog sib npaug nrog 900 hv), ua rau aliole 3x ntau dua {10} {tiv taus tshaj manganese steel.
