Kaolin uboya: iinzuzo kunye nobubanzi

Vata ibandakanya kaolin mullite ifayibha kwaye igqalwa izixhobo usambathisa thermal. Eyahluke ukumelana nomlilo kunye nayo kusetyenziswa ukugcwalisa imigodi kwi wamatye kunye Ekungeneni itywina slot.

incazelo

Material lidla kuphunyezwa ngohlobo rolls. Oveliswa kwinkqubo ukunyibilika oxides lesilicon aluminium kwiqondo lobushushu eliphezulu emlilweni ezizodwa. Kaolin wool iminyaka emininzi esetyenziswayo ngokubonakalayo ngenxa yokugquma wobushushu izakhiwo kunye outperforms nezinye izinto ezininzi. Nakuba iintlobo mihla ezinye arhente ngempahla ezifanayo, kuya kusiba zithandwa ngakumbi waza wafumana ukusetyenziswa kwayo izicelo mveliso. Kusebenza izixhobo msinga yokugquma, amagumbi yokutsha, kubananisi ubushushu kunye turbines. Eyona ngokubanzi kolu shishino. Kwakhona kaolin uboya isetyenziswa ekwenziweni Iizilebhu kunye nezinye izinto ukubunjwa.

Le nto iye isandi high level kunye yokugquma nobushushu, ukumelana deformation kunye nongcangcazelo imithwalo. Ukongeza, umqhaphu uye ezinye iimpawu ukuba uphawu izinto ezininzi ngenjongo efanayo. Indlela zokwambathisa alichatshazelwa lobushushu eliphezulu kwindawo cala okanye oxidizing, inqanaba ukumelana angandiswa yi ukusetyenziswa chromium oxide. Ngaphandle koku, le iphambili kukugcina ubushushu kakhulu reduced-bume ekunciphiseni.

buhle

Vata MKRR-130 ilungele ekudalweni wagaleleka pads, iiseti ezisongwayo lwe oveni kunye izakhiwo eludongeni. ubunzima bayo kunciphisa ixesha kunye nomgudu ezifunekayo ufakelo yaye kunciphisa iindleko zamafutha. Kubalulekile ukuphawula ezinye izinto ezintle:

• Imicu icocwe kakuhle luphawulwa nokumelana eliphezulu ukuya devitrification;
• inqanaba elincinane sokuzuza ubushushu;
• ukumelana yashiya thermal;
• ukugcinwa lweempawu original ngexesha ukusetyenziswa ngokuphindaphindiweyo;
• ngezinga eliphezulu usambathisa ephilileyo;
• It alichatshazelwa ndlongondlongo imichiza, alkalis nentsimbi linyibilike;
• egalelwe namafutha ngokusekelwe yezimbiwa oyile, kunye nomphunga wamanzi;
• iimpawu zombane azitshintshanga nokuba kwiqondo lobushushu eliphezulu.

iimpawu

Kaolin zoboya eyenziwe alumina elinjubaqa, olusekelwe phezu kwentlabathi zwi. Eziko ekhethekileyo esikrwada-lokunyibilikisa inyibilikiswa kwiqondo lobushushu degrees 1800. Xa zone yokunyibilika langoku electrode ezintathu, lo gama kwisiza isizukulwana zabo ezimbini kuphela. ubuchule makazichaze osetyenziswa ukunyibilika umbandela, busekelwe phezu ifuthe zomphunga ekhethekileyo ngaphandle kokuba uxinzelelo malunga 0.7 MPA. Ejection umlomo uvumela sicatshulwa zonke inkqubo kubethwa. Njengoko yokuhlanganisa enze iglasi yamanzi, udongwe okanye isamente.

Vata kaolin ethengiswa imiqulu ngeemitha ukuya ku-10 ubude, ubukhulu kunye nobubanzi-2 cm kunye-60 cm, ngokulandelelana. Ngoko ke guquka, ngaloo ndlela kubonelelwa ingangeni Ukufudumala nasiphi kuyilo. Namhlanje, abavelisi bazama ukuphucula izinto ngokuthi kongezwe components ezongeziweyo, umzekelo yttria. Oku kuphucula uzinzo imicu kwaye yandisa nokusebenzisa amathuba.

Materials ukumelana nomlilo

izinto eliyinjubaqa ezenziwe iziseko izimbiwa kunye abanganyangekiyo amaqondo obushushu aphezulu, kunye neempawu zazo kuhlala ingatshintshwanga. Bona ezibalulekileyo kushishino ngentsimbi ye ye neyanamhlanje, eguqukayo kunye nezinye iinkqubo, ukwakhiwa kwenkqubo ye-lobushushu eliphezulu (Motors, zamandla) kunye namacandelo kubo. Emva kokusebenzisa refractories bathunyelwa ukuba ngokurisayikilisha.

Amaninzi, olu hlobo mveliso ngokumila uxande ubunzima ephantsi, okuwenza abalungele lining ezahlukeneyo. Okwangoku, kukho ukwehla elula kwimveliso refractories, njengoko ingqalelo ngakumbi ihlawulwe ukuveliswa mortars ezizodwa kunye concretes, ukumelana kumaqondo obushushu aphezulu.

izinto eliyinjubaqa: iindlela mveliso

izinto Zinelungelo matrix yodongwe eyenziwe borides elinjubaqa, nitrides, oxides yaye inqanaba eliphezulu inertness kwemichiza elide. Kwakhona wayedla carbon compound. Eliyinjubaqa kugcina impahla yayo xa isetyenziswe lobushushu phakathi izidanga 1600 kwaye zisetyenziswa kwiindawo ezininzi apho kukho imfuneko naliphi na inyathelo kwiimeko anikiweyo. Ngokutsho indlela yokutshata iimveliso zahlulwe iintlobo:

• eshushu Siyabandezelwa;
• ingxubevange, processed ukusuka anyibilike;
• plastic bokwakha;
• ingxubevange ngokusekelwe penoshlikera wamanzi;
• ukusika iibhloko zigqithiswe okanye ngamatye.
