Cov txheej txheem ntau heev thiab cov txheej txheem ntawmFerro Silicon magnesium alloymuaj raws li nram no:
1, raw khoom npaj
Cov ntaub ntawv nyoos tseem ceeb muaj xws li magnesia,ferrosilicon alloythiab hlau ore nrog qhov loj me. Magnesia yog qhov chaw ntawm magnesium ferrosilicon muab cov khoom silicon thiab hlau ntsiab, thiab hlau ore yog lub hauv paus ntawm hlau. Tsis tas li ntawd, lub ntiaj teb tsis tshua muaj neeg lossis yog siv rau hauv kev tsim covLub ntiaj teb tsawg magnesium Ferrro Silicon Alloy.
2, sib tov cov khoom xyaw
Raws li cov kev sib xyaw sib xyaw ntawm lub hom phiaj alloy, cov khoom siv roostately yog kom ntseeg tau tias qhov loj me ntawm cov ntaub ntawv raw yog cov khoom sib xyaw, tsim kom zoo rau kev saj tau zoo.
3, pub mis thiab preheating
Cov khoom xyaw raw yog pub rau hauv rauv taws (xws li cov khoom siv hluav taws xob, thiab cov hluav taws xob hluav taws xob ua kom zoo nkauj, thiab cov roj fais fab
4, ua tiav kev kho mob
Premelt cov ntaub ntawv raw hauv smelting rauv rau decompose thiab txo cov khoom tsis txaus ntseeg, nce cov khoom kub ntawm cov ntaub ntawv raw, thiab npaj rau tom qab melting thiab alloying.
5, smelting txheej txheem
Cov pa tsw qab zom:
Thaum cov ntaub ntawv raw ncav cuag ib qho kub thiab txias, cov lus teb smelting pib. Nyob rau lub sijhawm no, txo cov neeg sawv cev, slag, thiab lwm yam tuaj yeem txuas ntxiv rau kev tswj hwm lub Alloy muaj pes tsawg leeg thiab txhawb kev tawm ntawm cov nyom. Piv txwv li, hauv qee cov txheej txheem, silicon yog siv los ua tus neeg sawv cev txo cov neeg sawv cev kom hnov cov tshuaj magnesium ntawm qhov kub.
Cov nta ntawm cov cua sov sib txawv:
Submerged arc rauv:
Nws yog ib qho ntawm cov khoom siv uas nquag siv rau kev tsim cov av tsis tshua muaj kev kub ntxhov. Nws siv cov cua sov ntawm ARC thiab cov cua sov tsim los ntawm kev tiv thaiv tus nqi them rau smelt, thiab noj hluav taws xob ntau.
Nruab Nrab Zuag Cub:
Ntxiv npaj cov khoom nyoos xws li ferrosilicon,Magnesium hlau, SCRAP hlau,calcium silicon, Ntiaj teb tsis tshua muaj ferrosilicon, thiab lwm yam rau hauv qhov cub thiab yaj lawv nrog hluav taws xob. Txawm li cas los xij, nyob rau hauv cov qauv no, magnesium yog ib qho yooj yim rau melt ua ntej thiab sib txuas nrog cov pa roj ua ke kom tsim ntau cov pa roj hlau kom tsim cov khoom lag luam zoo.
Ib-qib qauv ntawm hluav taws xob arc rauv:
Ua ntej, lwm cov khoom siv raw tsuas yog magnesium hlau, txiv qaub, seem av thiab tsis tshua muaj cov zaub mov ua kom sib luag rau kev sib tw. Tom qab tus nqi yog melted, qhov ntsuas kub tau tsa los ua lub txiv qaub, tsis tshua muaj ntiaj teb thiab silicon hauv ferrosilicon hnov mob. Thaum cov ntsiab lus SI, CA, RE, FE thiab lwm yam hauv cov kua alloy ua tau raws li qhov yuav tsum tau ua tiav, nws tau coj tawm ntawm lub cub tawg. Tom qab ntawd cov kua tshuaj yog hliv rau hauv lub hau melting nrog lub hau thiab cov tshuaj khib nyiab tau nias rau hauv qab no. Thaum kawg, lub hau yog nias thiab nrum.
6, alllo casting
Thaum smelted alloy muaj pes tsawg leeg ua raws li qhov yuav tsum tau ua, nws yog nchuav tawm ntawm cov cua sov thiab pwm lossis rov qab ua ke. Tus txheej txheem no yuav tsum nruj tswj cov dej twj kub thiab nrawm thiab txoj kev kom paub tseeb tias qhov zoo thiab cov duab ntawm alloy ua raws li cov qauv.
7, cov txheej txheem tom qab ua
Xws li kev tshem tawm slag, kev zam, kev zam txim, kev kho cua sov thiab lwm yam txuas ntxiv txhim kho cov khoom tiav tiav thiab tau txais cov khoom tiav.
