Kaolin uvolo: izinzuzo futhi ububanzi

Vata siqukethe kaolin mullite fibre futhi libhekwa njengoba ezishisayo ukwahlukanisa izinto. It ahluke ukumelana nomlilo futhi liyasetshenziswa ukugcwalisa imigodi ku wokwakha futhi uphawu slot ukuvuleka.

incazelo

Material ngokuvamile ukusebenza ngendlela imiqulu. It ikhiqizwa inqubo encibilika Silicon oxides kanye ne-aluminium ngamazinga ashisa kakhulu e amaziko ekhethekile. Kaolin uvolo iminyaka eminingi isiphethwe osetshenziselwa zifudumele izakhiwo kanye outperforms ezinye izinto eziningi. Naphezu ezihlukahlukene zanamuhla yezinye agents nge izakhiwo efanayo, kuba zithandwa kakhulu futhi zitholakala wathola elisetshenziswa izicelo ezimbonini. It uba amadivayisi a ezishisayo ukwahlukanisa, amandla omlilo emakamelweni, ukushisa kanye abaphehla ugesi. I kabanzi kunazo kuphawuliwe umkhakha. Futhi kaolin uvolo isetshenziswa womshini slabs nezinye izinto olubunjiwe.

Indaba has a high level umsindo nokushisa ukwahlukanisa, ukumelana ukusonteka vibration imithwalo. Ngaphezu kwalokho, ukotini has nezinye izakhiwo ukuthi kukhona isici izinto eziningi nge injongo efanayo. Izindlela nangokuvikela alithintwa okushisa aphakeme e imvelo hlangothi noma oxidizing, ezingeni ukumelana zingandiswa ngokusebenzisa chromium oxide. Naphezu kwakho konke lokhu, isici esiyinhloko iwukuhlale yokushisa kakhulu encishisiwe esimweni ukunciphisa.

izinzuzo

Vata MKRR-130 ilungele ukudalwa kwabhoboka pads, ukwahlukanisa amasethi Ohhavini nodonga ezakhiwe. Isisindo sayo esincane kunciphisa nesikhathi edingekayo futhi umzamo odingekayo ukuze ukufakwa futhi kunciphise nezindleko nophethiloli. Kuyaphawuleka nezinye izici ezinhle:

• Imicu yotshani bahlanza kahle zinezikhathi ukumelana devitrification;
• izinga eliphansi kunawo wonke ukushisa ekuqongeleleni;
• ukumelana ukushaqeka ezishisayo;
• ekulondolozweni izici yasekuqaleni phakathi Ukulisebenzisa ngokuphindaphindiwe;
• ngezinga eliphezulu ukwahlukanisa umsindo;
• It is hhayi ehlaselwe nolaka amakhemikhali, alkalis nensimbi liyancibilika;
• inert namafutha esekelwe uwoyela amaminerali, futhi amanzi umusi;
• izici kagesi zihlala zinjalo ngisho noma kushisa kakhulu.

Izici

Kaolin uvolo wenza alumina refractory, ogxile asebenza ngebhethri isihlabathi. Ku-ore-sokuncibilikisa esithandweni ekhethekile Incibilikile ezingeni lokushisa 1800 degrees. Esikhathini indawo ukuncibilika ukwethula electrode ezintathu, kanti endaweni esizukulwaneni sabo ezimbili kuphela. amasu ekushayweni isetshenziselwa encibilika indaba, kusekelwe umthelela umusi ekhethekile enikeziwe ukuthi ukucindezela mayelana 0.7 MPA. Ejection umlomo wombhobho ivumela ukudlula zonke inqubo ukushaywa. Njengoba binders bangase benze amanzi ingilazi, ubumba noma usimende.

Vata kaolin okuthengiswa imiqulu amamitha angu-10 ubude, ukujiya kanye ububanzi 2 cm cm 60, ngokulandelana. Kuyinto nezimo, ngalokho lunikeze ngumuntu okwaziyo Ukuthokomala nganoma yisiphi design. Namuhla, abakhiqizi abazama ukuthuthukisa indaba ukwengeza izingxenye ezengeziwe, isibonelo yttria. Lokhu kwenza kube ngcono ukuzinza zemicu enwetshiwe ukusetshenziswa amathuba.

Izinto ukumelana nomlilo

izinto Refractory wenza kusukela elisekela amaminerali kanye amelana okushisa aphakeme, futhi izici zabo zihlala zinjalo. Bona azinakusilela umkhakha steel ziphuzo zazihluzwa, izinqubo oluyingozi nezinye, ukudalwa izindlela ephezulu lokushisa (izinjini, sikhungo) futhi izingxenye ngabo. Ngemuva kokusebenzisa Refractories ithunyelwa khona udoti.

Ngokuvamile, lolu hlobo umkhiqizo has simise elingunxande nesisindo ongaphakeme, abenze ekahle ulwelwesi ehlukahlukene. Okwamanje, kukhona ukwehliswa elula ekukhiqizeni Refractories, njengoba kakhudlwana ikhokhelwa ukukhiqizwa izigqulo akhethekile Concretes, ukumelana namazinga okushisa aphakeme.

izinto Refractory: izindlela yokukhiqiza

izinto Sinenkosi matrix Ceramic eyenziwe borides refractory, nitrides, oxides futhi abe ezingeni lelisetulu inertness chemical futhi ihlala isikhathi eside. Futhi ngokuvamile sisetshenziswa carbon kwakwakhe. Refractory ukugcina izakhiwo zabo lapho zihlatshwa lokushisa phakathi 1600 degrees futhi zisetshenziswa ezindaweni eziningi lapho kukhona isidingo sokwenza e izimo inikezwe. Ngokusho indlela yokwakha imikhiqizo zihlukaniswe izinhlobo eziningana:

• hot ecindezelwe;
• ingxubevange, kusetshenzwe kusuka ukuncibilika kwezinguzunga;
• plastic ukwakha;
• ingxubevange esekelwe penoshlikera uketshezi;
• usike kusukela amabhlogo kusetshenzwe noma amatshe.
