Chishandiso chikuru chekunyungudutsa simbi isiri-ferrous ndeye-non-ferrous metal smelting furnaces. Kudzidza kudiwa kwemhando dzakasiyana-siyana uye kunaka kwezvinhu zvinoramba zvichikonzerwa nekufambira mberi kwetekinoroji yeindasitiri yekunyungudutsa simbi kunofanirwa kuve iro basa guru reiyo refractory indasitiri yekuwedzera hupenyu hweasiri-ferrous simbi yekunyungudutsa mavira uye kuwedzera kugadzirwa.
1. Indasitiri yekunyungudutsa mhangura
Nzira yekugadzira mhangura ndiyo ine nzira dzakawanda mumatare akasiyana-siyana asina-ferrous. Iyo nzira yekugadzira mhangura munyika yangu haingosanganisire maitiro ese emhangura munyika, asi zvakare inosanganisira yakasarudzika nzira munyika yangu, senge sirivheri yekunyungudutsa nzira yemhangura uye oksijeni pasi. Furidzira choto chinonyunguduka.
Mukuita kunyungudutswa kwemhangura yemoto, mutsauko unonyanya mukugadzirwa kwemhangura matte, nepo inoshandura inofuridza nekunatsa mhangura zvakangofanana.
Nekuda kwekushisa kwepamusoro mushongwe yekupindura yevira remoto, mhepo inomhanya-mhanya yakasanganiswa neyakanyunguduka inoshatisa uye inoshatisa iyo reaction tower. Parizvino, yakasanganiswa magnesia-chrome zvidhinha zvinoshandiswa. Panguva imwecheteyo, kuitira kuchengetedza magnesia-chrome zvidhinha zvakasanganiswa, akati wandei akachinjika emhangura ndiro majaketi emvura akaiswa sandwich mune zvidhinha masonry, uye mvura-yakatonhorera yemhangura mapaipi kana vertical mhangura ndiro yemvura jaketi inorongwa pakati pezvidhinha masonry. goko. , pamusoro peiyo reaction tower uye yekumusoro yakadzika tembiricha nzvimbo inovakwa neyakajairwa magnesia-chrome zvidhinha. Muchikamu chekubatanidza pakati peiyo reaction tower uye nechepamusoro petangi yekunyungudutsa (saizvozvowo kubatana pakati pesedimentation tank uye inokwira flue), iri pasi pekukukurwa uye kusimba kwakasimba kwekunyunguduka kwepamusoro-tembiricha kunyunguduka uye guruva-rakaremerwa nepamusoro-tembiricha. kuyerera kwemhepo, uye lining iri nyore kukuvadzwa, saka mhangura yakacheneswa inowanzoshandiswa. Chimiro chemhando yepamusoro magnesia-chrome zvidhinha zvakaiswa nepombi tamping refractory castables kana majaketi emvura emhangura.

2. Lead uye zinc industry
Lead-zinc airtight blast furnace
Lead-zinc airtight blast furnace isimbi yakakosha inonyungudutsa simbi mbiri dzinotungamira uye zingi panguva imwe chete mumudziyo mumwe. Hunhu hwayo ndehwekuti 800-850 ℃ mhepo inopisa inoshandiswa pakuputika; kumusoro kwechoto kunochengetwa pakupisa kukuru kwe1050-1100 ℃; Nzvimbo yemoto ye-lead-zinc airtight blast furnace inovakwa nemagnesia zvidhinha, nzvimbo yemoto ijasi remvura, mutumbi wevira unovakwa nepamusoro-aluminium zvidhinha, uye pamusoro pechoto chinoputirwa ne-high-alumina unshaped refractory materials. Mibhedha yekumberi yelead-zinc airtight blast furnaces ese emagetsi ekudziisa pamberi pemibhedha, uye hupenyu hwavo hwesevhisi hwakaderera pane hwehuni hwekuputika. Kunyanya nekuda kwekukukurwa kwe slag uye scouring slag mitsetse. Parizvino, maviri e lead-zinc airtight blast furnaces muChina akaiswa chrome slag zvidhinha uye aluminium-chromium-titanium zvidhinha zvakateerana. Kunyangwe zera rechoto rinogona kusvika kupfuura gore re1, richiri rakaderera pane hupenyu hwe lead-zinc airtight blast furnaces. Nzira yekuenderera mberi nekuvandudza hupenyu hwehuto hwemagetsi ekupisa pamberi pemubhedha kuti uenderane nehupenyu hwekutungamirira-zinc airtight blast furnace ndiyo kiyi yekuvandudza kushanda kweiyo lead-zinc airtight blast furnace.
