Izitini ze-SK32 kanye ne-SK34: Ilungele izimboni ezinezinga lokushisa eliphezulu

Emhlabeni wokusetshenziswa kwezimboni zokushisa okuphezulu, izitini ze-SK32 kanye ne-SK34 zigqama njengezixazululo ezinokwethenjelwa neziphezulu - eziphikisayo zokusebenza. Lezi zitini ziyingxenye yochungechunge lwe-SK lwezitini ze-fireclay, ezaziwa ngokumelana nokushisa kwazo okukhethekile nokuqina kwazo.

1. Ukwakhiwa kanye Nokukhiqiza

Izitini ze-SK32 kanye ne-SK34 ze-fireclay zakhiwe ngezinto ezingavuthiwe ezinhle kakhulu, okuhlanganisa ubumba oluphikisayo, i-chamotte eqoshiwe, ne-mullite. Inqubo yokukhiqiza ihilela amasu athuthukile aqinisekisa ukuthi izitini zine-porosity ephansi, amandla aphezulu, nokumelana okuhle kakhulu nokukhishwa kwe-thermal, ukuhuzuka, nokugqwala.

Izitini ze-SK32

Izitini ze-SK32 ngokuvamile zine-alumina engu-35 - 38%. Lokhu kuqanjwa kubanika i-refractoriness engu-≥1690 °C kanye ne-refractoriness ngaphansi komthwalo (0.2 MPa) ye-≥1320 °C. Ane-porosity ebonakalayo engu-20 - 24% kanye nokuminyana kwenqwaba okungu-2.05 - 2.1 g/cm³.

Izitini ze-SK34

Izitini ze-SK34, ngakolunye uhlangothi, zinokuqukethwe okuphezulu kwe-alumina, okusukela ku-38 - 42%. Lokhu kuphumela ekukhanyeni okuphezulu okungu-≥1710 °C kanye ne-refractoriness ngaphansi komthwalo (0.2 MPa) we-≥1340 °C. I-porosity yabo ebonakalayo ingu-19 - 23%, kanti ukuminyana kwenqwaba kungu-2.1 - 2.15 g/cm³.

2. Izicelo

Ngenxa yezakhiwo zazo ezivelele, izitini ze-SK32 kanye ne-SK34 zithola ukusetshenziswa okubanzi ezimbonini ezihlukahlukene zokushisa okuphezulu.

Izitshalo Zensimbi

Ekwenziweni kwensimbi, izitini ze-SK34 ziyindlela - ukukhetha amalayini esithandweni somlilo, amaladi, nezinye izinto zokusebenza ezishisa kakhulu. Izimo zokushisa ezidlulele ezitshalweni zensimbi zidinga izinto ezinokumelana nokushisa okuphezulu, futhi izitini ze-SK34 ziwufanela kahle umthethosivivinywa. Ziyakwazi ukumelana nokushisa okukhulu futhi zivikele izakhiwo ezingaphansi emonakalweni

Izitini ze-SK32, ezinokumelana kwazo nokushisa okuphansi kancane kodwa ukusebenza okumangalisayo, zivame ukusetshenziswa ezindaweni zensimbi ezichayeke ekushiseni okusesilinganisweni, njengamalayini athile esithandweni lapho izimfuneko zokushisa zingeqisi kangako.​

Imboni Yezobumba.

Zombili izitini ze-SK32 kanye ne-SK34 zivame ukusetshenziswa kumahhani e-ceramic. Izitini ze-SK32 zifanele ama-kilns asebenza emazingeni okushisa aphakathi nendawo, ahlinzeka ngokufakwa okuthembekile nokumelana nokushisa. Izitini ze-SK34, ezinamandla azo okumelana nokushisa okuphezulu, zisetshenziswa eziko lapho kubandakanyeka amazinga okushisa adlulele kakhulu, okuqinisekisa ikhwalithi yemikhiqizo yobumba ngesikhathi sokudubula.

Izitshalo zikasimende

Ezikosini ezijikelezayo zikasimende, izitini ze-SK32 kanye ne-SK34 zidlala indima ebalulekile. Ukuchayeka isikhathi eside emazingeni okushisa aphezulu kanye nezinto ezigugulekayo ezitshalweni zikasimende kudinga izitini eziphikisayo ezinamandla amakhulu okusebenza kanye nokungagugi. Izitini ze-SK32 zisetshenziswa ezingxenyeni zehhavini lapho ukushisa kungenamazingeni aphezulu, kuyilapho izitini ze-SK34 zifakwa ezindaweni ezingaphansi kokushisa okunzima kakhulu, njengendawo evuthayo yesiko.​

Izitshalo ze-Petrochemical and Chemical

Izitini ze-SK34 zisetshenziswa kakhulu kuma-reactors namathuluzi ashisayo ezitshalweni ze-petrochemical kanye namakhemikhali. Lezi zitshalo zivame ukubhekana nokuguquguquka kwamakhemikhali okushisa okuphezulu, kanye nekhono lezitini ze-SK34 ukumelana nokushisa nokugqwala kwamakhemikhali kuzenza ukukhetha okuhle. Izitini ze-SK32 zingasetshenziswa kwezinye izinhlelo zokusebenza ngaphakathi kwalezi zitshalo lapho izimo zokushisa ziphakathi nendawo

3. Izinzuzo

Izitini ze-SK32 kanye ne-SK34 zinikeza izinzuzo ezimbalwa ezizenza zifiseleke kakhulu ekusetshenzisweni kwezinga lokushisa eliphezulu.​

Ukumelana Nokushisa Okuhle Kakhulu

Njengoba kushiwo ngaphambili, zombili izinhlobo zezitini zingakwazi ukumelana namazinga okushisa aphezulu. I-refractoriness ephezulu kanye nokusebenza okuhle ngaphansi komthwalo kuqinisekisa ukuthi bangakwazi ukugcina ubuqotho babo besakhiwo ngisho nasezimweni ezinzima kakhulu zokushisa - izindawo ezicindezela kakhulu.

I-Low Thermal Conductivity

Ane-conductivity ephansi ye-thermal, okusho ukuthi anciphisa ukulahlekelwa ukushisa. Le ndawo ayizuzisi nje kuphela ukugcina izinga lokushisa elifunekayo ngaphakathi kwemishini yezimboni kodwa futhi isiza ekwehliseni ukusetshenziswa kwamandla. Ngokuvimbela ukushisa ukuthi kungaphumi, izitshalo zingasebenza kahle kakhulu futhi zibize - ngempumelelo

Amandla Emishini Ephakeme.

Izitini ze-SK32 kanye ne-SK34 zinamandla amakhulu okusebenza. Lokhu kuzivumela ukuthi zibekezelele ukucindezelwa kwemishini, ukuhuzuka, kanye nomthelela okwenzeka kuzilungiselelo zezimboni. Ubuqotho babo besakhiwo buqinisekisa impilo ende yesevisi, kunciphisa isidingo sokushintshwa njalo futhi ngaleyo ndlela konga ezindlekweni zokunakekela.

Ukumelana Kahle Nokushisa Okushisayo kanye Nokugqwala

Izitini zimelana kakhulu ne-thermal spalling, okuwukuqhekeka noma ukuxebuka kwezinto ngenxa yoshintsho olusheshayo lokushisa. Baphinde banikeze ukumelana okuhle kakhulu nokugqwala, ikakhulukazi ezindaweni ezicebile ngamakhemikhali. Lokhu kubenza bafanelekele ukusetshenziswa ezinhlobonhlobo zezimboni lapho izinselele ezinjalo zivamile khona

4. Ukukhetha Isitini Esilungile

Lapho unquma phakathi kwezitini ze-SK32 ne-SK34 zohlelo oluthile, izici ezimbalwa zidinga ukucatshangelwa.
Izimfuneko Zezinga lokushisa

Isici esibaluleke kakhulu izinga lokushisa isitini esizochayeka kulo. Uma isicelo sibandakanya amazinga okushisa aphakeme ngokwedlulele, njengasezithandweni zokwenziwa kwensimbi noma iziko elithile lokushisa eliphezulu, izitini ze-SK34 ziyisinqumo esisobala. Nokho, ezinhlelweni zokusebenza ezinamazinga okushisa aphakathi nendawo, izitini ze-SK32 zinganikeza isixazululo esibiza kakhulu - esisebenza ngempumelelo ngaphandle kokudela okuningi ekusebenzeni.​

I-Chemical Environment

Ukwakhiwa kwamakhemikhali emvelo lapho isitini sizosetshenziswa khona kubalulekile. Ezindaweni ezinamazinga aphezulu amakhemikhali agqwalayo, ukumelana nokugqwala okungcono kwezitini ze-SK34 kungase kudingeke. Kodwa uma ukuchayeka kwamakhemikhali kukuncane, izitini ze-SK32 zingase zanele
Izindleko zokucatshangelwa

Izitini ze-SK32 ngokuvamile zibiza kakhulu - zisebenza kahle kunezitini ze-SK34. Uma izinga lokushisa nezidingo zamakhemikhali zohlelo lokusebenza zivumela, ukusebenzisa izitini ze-SK32 kungasiza ekwehliseni izindleko zephrojekthi zizonke. Kodwa-ke, kubalulekile ukuthi ungayekethisi ekusebenzeni ngenxa yokonga izindleko

Sengiphetha, izitini ze-SK32 kanye ne-SK34 ziyizinto ezimbili ezithembeke kakhulu zokuphikisa ezitholakalayo ekusetshenzisweni kwezimboni zezinga lokushisa eliphezulu. Izakhiwo zabo ezihlukile, uhla olubanzi lwezicelo, kanye nezindleko - ukusebenza kahle kubenza babe ukukhetha okuhle ezimbonini ezahlukahlukene. Kungakhathaliseki ukuthi imboni yensimbi, imboni ye-ceramics, isitshalo sikasimende, noma indawo ye-petrochemical, lezi zitini zinganikeza ukumelana nokushisa okudingekayo nokuqina ukuze kuqinisekiswe ukusebenza kahle nangempumelelo.
