Tsis tshua muaj lub ntiaj teb magnesium ferrosilicon alloy(lub npe hu ua RE MgSiFe alloy) yog ib qho tseem ceeb tsis tshua muaj lub ntiaj teb alloy nrog cov tshuaj muaj pes tsawg leeg thiab cov yam ntxwv.
Tshuaj muaj pes tsawg leeg
1. Magnesium (Mg):Raws li cov ntsiab lus tseem ceeb ntawm cov hlau, magnesium muaj cov khoom ua haujlwm zoo thiab cov khoom siv kho tshuab.
2. Silicon (Si):Silicon tuaj yeem txhim kho corrosion kuj thiab thermal stability ntawm alloy.
3. Hlau (Fe):Hlau feem ntau yog siv los ua cov khoom txhawb nqa kom muaj zog thiab hardness ntawm cov hlau.
4. Rare ntiaj teb cov ntsiab lus:Tsis tshua muaj lub ntiaj teb cov ntsiab lus xws li lanthanum (La), cerium (Ce), neodymium (Nd), thiab lwm yam tuaj yeem txhim kho lub cev thiab tshuaj lom neeg tshwj xeeb ntawm cov hlau, xws li kev txhim kho qhov kub thiab txias thiab oxidation tsis kam.
Yam ntxwv
1. Kev ua haujlwm siab kub:Tsis tshua muaj lub ntiaj teb magnesium ferrosilicon alloy muaj qhov kub thiab txias ruaj khov thiab oxidation tsis kam vim qhov sib ntxiv ntawm cov ntsiab lus tsis tshua muaj hauv ntiaj teb, thiab tsim nyog rau kev siv hauv qhov kub thiab txias.
2. Corrosion kuj:Qhov sib ntxiv ntawm silicon txhim kho corrosion kuj ntawm cov alloy, muab nws lub neej ntev kev pab cuam nyob rau hauv hnyav ib puag ncig.
3. Lub zog thiab hardness:Qhov sib ntxiv ntawm cov hlau txhim kho lub zog thiab hardness ntawm cov hlau, ua rau nws tsim nyog rau lub sijhawm uas xav tau cov khoom siv tshuab siab dua.
4. Electrochemical khoom:Cov ntsiab lus tsis tshua muaj hauv ntiaj teb tseem cuam tshuam rau kev coj tus cwj pwm electrochemical ntawm alloys, uas tuaj yeem txhim kho lawv daim ntawv thov kev ua tau zoo hauv kev ua haujlwm ntawm electrochemistry.
Kev ua lag luam
Tsawg-magnesium spheroidizers nrog cov ntsiab lus magnesium ntawm 4%, 5%, thiab 5.5%, nrog RE ntawm 1% thiab 2%, feem ntau yog siv rau nruab nrab-frequency furnace smelting thiab spheroidization ntawm tsawg-sulfur hlau kua. Nws muaj qhov zoo ntawm cov tshuaj tiv thaiv spheroidization maj mam thiab yooj yim nqus ntawm spheroidizing ntsiab.
Medium-magnesium series spheroidizers nrog cov ntsiab lus magnesium ntawm 6% thiab 7%, feem ntau yog siv rau cupola thiab hluav taws xob rauv ob chav smelting, los yog nruab nrab-frequency furnace smelting ntawm pearlite cam khwb cia hlau hlau castings. Raws li cov phab ntsa thickness ntawm cov casting thiab cov ntsiab lus leej faj ntawm cov hlau molten qub, qhov tsim nyog tus nqi ntawm spheroidizer yog txiav txim siab, nrog rau ntau yam kev siv thiab ntau yam kev kho spheroidization txheej txheem.
High-magnesium series spheroidizers yog tsim rau cupola smelting thiab molten hlau nrog sulfur ntsiab lus ntawm 0.06%-0.09%, thiab cov nyiaj ntxiv yog nruab nrab ntawm 1.6% thiab 2.0 %.
Spheroidizer, vermicularizer thiab inoculant rau cam khwb cia hlau. Tsis tshua muaj lub ntiaj teb magnesium ferrosilicon alloy, tseem hu ua magnesium alloy spheroidizer, yog ib qho zoo inoculant nrog lub zog txhua yam thiab muaj zog deoxidation thiab desulfurization los.
Steelmaking additives: Lub teeb tsis tshua muaj lub ntiaj teb magnesium ferrosilicon alloy siv hauv kev tsim cov spheroidizers, vermicularizers thiab inoculants kuj yog siv los ua tus neeg sawv cev ntxiv thiab alloying hauv kev tsim cov hlau thiab hlau. Nws yog siv rau refining, deoxidation, denaturation, neutralization ntawm low-melting point teeb meem impurities (Pb, arsenic, thiab lwm yam) thiab cov khoom tov alloying los tsim cov hlau tebchaw tshiab los purify steel.
Feem ntau, lub ntiaj teb tsis tshua muaj magnesium ferrosilicon alloy tau dhau los ua ib qho ntawm cov ntaub ntawv tseem ceeb hauv ntau qhov chaw ua haujlwm siab vim nws cov tshuaj lom neeg tshwj xeeb thiab kev ua tau zoo heev, txhawb kev txhim kho kev lag luam niaj hnub thiab thev naus laus zis.
