Ndezvipi zvimisikidzo zvembatya zvechikamu chega chega che blast furnace inopisa blast stove?

The refractory configuration analysis of each part of the blast furnace hot blast stove inogoverwa nevagadziri vezvidhinha vanoramba.

Iyo blast furnace inopisa blast stove ndeye inogadziridza kupisa inotsinhanisa, kunyanya kupa yakanyanya tembiricha yekudziya nharaunda yemhepo inopfuta ye blast furnace kuti iwane yakanyanya kushanda tembiricha yemhepo, kazhinji 1200 ~ 1350 ℃. Iwo akajairika anofananidzwa anopisa anoputika mavira emoto anoputika ari 3 ~ 4. Kuti zvizadzise zvinodikanwa zvekupisa tembiricha sosi uye nguva yakareba sevhisi yehuni dzinopisa, zvinhu zvinoramba zvemoto zvinopisa zvinofanirwa kuve nehunhu hwekupisisa tembiricha yekupisa uye kushivirira kwakanyanya, kuramba kwakanaka kwekukwira, hombe chaiyo yekupisa, uye yakanaka thermal conductivity. .

Zvinoenderana nechimiro chechikamu chimwe nechimwe chechitofu chinopisa uye pesvedzero yemamiriro echoto, zvinhu zvinoramba zvechitofu chinopisa chinogona kukamurwa kuita zvikamu zviviri: kupisa kwakanyanya uye kuderera kwekushisa. Zvikamu zvekushisa kwepamusoro: kusanganisira chikamu chepamusoro chekamuri inopisa, cheki zvidhinha pane chikamu chepamusoro chekugadzirisa, zvidhinha zvakakura zvemadziro, pamusoro pechoto, nezvimwewo; zvikamu zvekushisa zvepakati uye zvakaderera: zvinosanganisira nzvimbo dzepakati nepamusoro dzekamuri inopisa, checkered zvidhinha pakati nepakati pezvikamu zve regenerator, zvidhinha zvakakura zvemadziro, uye zvikamu zvekubuda, nezvimwewo.

Zvinoenderana nechimiro chechitofu chinopisa chinopisa, chinogona kukamurwa kuita: pamusoro pechoto, madziro makuru ejenareta, chidhinha checheki, madziro ekuparadzanisa, madziro makuru ekamuri rinopisa, chinopisa uye zvimwe zvikamu. .

1. Refractory kumusoro kwechoto:

Kumusoro kwechoto kunowanikwa munzvimbo yepamusoro yekupisa mukati mevira rinopisa rinopisa, uko iyo refractory zvinhu zvinosangana zvakananga nemhepo inopisa uye flue gasi. Iyo refractory zvinhu ine yakasimba thermal shock resistance uye creep resistance inofanira kusarudzwa. Kazhinji, zvidhinha zvesilica uye zvidhinha zvevhu zvakaderera zvinogona kushandiswa. Zvidhinha zvakakwirira zvealumina, zvidhinha zvakakwirira zvealumina, zvidhinha zvemullite, zvidhinha zvevhu zvakapfava, zvidhinha zveandalusite, pendi inopfapfaidza acid, pendi yevhu, nezvimwe.

2. Refractory zvinhu zvemadziro makuru e regenerator:

Rusvingo rwakakura rweregenerator rusvingo rukuru rwechitofu chinopisa chitofu, uko kutonhora kwepamusoro kunenge kwakakwirira, uye kutonhora kwemhepo pakati nepakati pezvikamu zvishoma zvishoma. Chikamu chepamusoro chemadziro makuru emugadziriso anogona kushandisa silica zvidhinha, yakaderera inokambaira yakakwira alumina zvidhinha, uye yakakwirira aluminium kupisa kupisa. Zvidhinha, zvidhinha zvemullite, zvidhinha zvevhu zvakareruka, pendi yepfapfaidzo isingamiri, pendi yekupfapfaidza yakareruka, nezvimwe.

Pakati pepakati, yakaderera inokambaira yakakwira alumina zvidhinha, mullite zvidhinha, andalusite zvidhinha, zvidhinha zvevhu, ivhu rekupfapfaidza pendi, mwenje wekupfapfaidza pendi, nezvimwe zvinogona kushandiswa.

Chikamu chepasi chinogona kushandisa zvidhinha zvevhu, zvidhinha zvakakwirira zvealuminium, zvidhinha zvevhu zvakapfava, zvidhinha zvakakwirira zvealumina, zvidhinha zvevhu, pendi dzakapfapfaidza, kongiri inodzivirira kupisa, nezvimwe.

3. Refractory zvinhu zvecheki zvidhinha:

Iyo yepamusoro-yepamusoro-yekushisa zone yecheki zvidhinha zve regenerator inofanira kugadzirwa nezvinhu zvinoramba zvine kunaka kwepamusoro-tembiricha kugadzikana, corrosivity uye creep resistance. Nzvimbo dzepakati nedzepasi dzinotakura kudzvanywa kukuru kubva kune yepamusoro refractory zvinhu. Pamusoro pekugutsa kuita kwayo kunokambaira, inodawo kuita kwakanaka kweyakajairika tembiricha yekumanikidza simba uye kupisa kwekutya kugadzikana.

Chikamu chepamusoro chezvidhinha checheki chinowanzo shandisa silicon cheki zvidhinha uye yakakwirira-aluminium cheki zvidhinha, chikamu chepakati chinoshandisa yakaderera-creep high-aluminium cheki zvidhinha uye yakakwirira-aluminium cheki zvidhinha, uye chikamu chepasi chinoshandisa yakaderera-creep high-aluminium cheki. zvidhinha nezvidhinha zvevhu.

Pamusoro pezvo, regenerator ye spherical hot blast stove inowanzo shandisa mabhora erefractory kutsiva zvidhinha zvecheki, anonyanya kuzivikanwa ndeakakwira alumina refractory mabhora, uye ivhu refractory mabhora anogona kushandiswa munzvimbo dzakaderera tembiricha.

4. Refractory zvinhu zvekuparadzanisa madziro:

The partition wall is refractory brick wall inoparadzanisa regenerator uye kamuri yekupisa. Kureba kwemadziro ekuparadzanisa kunowanzo 400 ~ 700mm yakakwirira kupfuura yecheki zvidhinha zve regenerator kuti ive nechokwadi chekugovera mhepo yakafanana. Nekuda kwemusiyano mukuru wetembiricha pakati pemativi maviri emadziro ekukamura, mutsauko wekupisa wekupisa wemadziro unova wakakura, izvo zvinoita kuti zvinhu zvinoramba zvemadziro emadziro kutsvedza, kukotama uye kutsemuka. Naizvozvo, silica zvidhinha uye yakakwirira alumina zvidhinha zvinogona kushandiswa pamusoro chikamu refractory zvinhu zvechikamu madziro.

High-alumina zvidhinha uye yakakwirira-aluminium insulation zvidhinha zvinogona kushandiswa pakati, uye pasi-creep high-alumina zvidhinha uye yakakwirira-aluminium insulation zvidhinha zvinogona kushandiswa mu thermal shock part.

Zvidhinha zvevhu uye zvidhinha zvevhu zvakareruka zvinogona kushandiswa kune chikamu chepasi.

5. Refractory zvinhu zvemadziro makuru ekamuri yekupisa:

Rusvingo rukuru rwekamuri rinopisa rinonyanya kufanana nechinhu chinoramba chekugadzirisa. Chikamu chepamusoro chinogona kushandisa silika zvidhinha, yakakwirira alumina zvidhinha, yakakwirira alumina insulation zvidhinha, akareruka silica zvidhinha, zvidhinha zvevhu, pendi yekupfapfaidza, nezvimwe.

High-alumina zvidhinha, pasi-creep high-alumina zvidhinha, high-alumina insulation zvidhinha, chiedza chevhu zvidhinha, spray pendi, nezvimwewo zvinogona kushandiswa pakati.

Chikamu chezasi chinogona kushandisa zvidhinha zvevhu, yakakwira alumina zvidhinha, zvidhinha zvevhu zvisingaremi, pendi yekupfapfaidza, kongiri inodzivirira kupisa, nezvimwe.

6. Burner nozzle:

The burner nozzle ndiyo midziyo inotumira gasi yakavhenganiswa mweya mukamuri yekupisa yekupisa. Kune simbi uye ceramic zvinhu. Parizvino, akawanda e ceramic burners anoshandiswa. Kuti uone kusimba kwemhepo, kutendeseka uye hupenyu hwesevhisi yehuni inopisa, Zvinodikanwa kuti mutsara wekuwedzera coefficient uye inokambaira kuramba yeanopikisa pano yakanaka, saka iyo inopisa muromo inogona kugadzirwa nemullite, mullite-cordierite, yakakwirira. -aluminium-cordierite, yakakwirira-aluminium castable preforms, nezvimwe.

7. Refractory zvinhu zvezvimwe zvikamu zvechitofu chinopisa:

(1) Refractory zvinhu zvepombi dzemhepo inopisa, kusanganisira mapaipi makuru ekupa mhepo, mapaipi ebazi uye mhepo inopisa yakatenderedza mapaipi. Kazhinji, inogadzirwa nevhu rakareruka zvidhinha, uye iyo inopisa mhepo yekubuda uye iyo huru yemhepo duct interface inogona kugadzirwa nepamusoro-alumina zvidhinha uye mullite zvidhinha. Iyo inopisa inoputika chitofu yakatenderedza pombi uye pombi yebazi rekupa mhepo inogona kudururwa pamwe nepamusoro-alumina simende refractory inokandwa uye phosphate refractory castable.

(2) Ivhavha yemhepo inopisa inogadzirwa nezvinhu zvinoramba, saka mativi ose ari maviri anopisa uye anoiswa pasi pemagetsi vibration, corrosion uye kuchinja kwekushisa. Hupenyu hwekugadzira zvidhinha zvevhu uye yakakwirira alumina zvidhinha ndeye 6 kusvika Gumiguru, uye yakakwirira alumina simenti refractory castables inoshandiswa. Kudurura hupenyu hwekuumba hunogona kusvika makore anenge 1.5.

(3) Refractory zvinhu zvinoshandiswa kune flue uye chimney. Iyo flue chimney inonyanya kushandiswa pakuburitsa gasi reflue. Iyo flue gasi yakareba kupfuura flue gasi. Naizvozvo, flue refractory zvinhu zvinogona kuvakwa nezvidhinha zvevhu, uye chimney chinogona kudururwa nekongiri. Chikamu chezasi chakaiswa nezvidhinha zvevhu sechidziviriro.
