Kaolin shinda: kubatsirwa uye kukura

Vata une kaolin mullite nokusanzwira uye semhosva kumbogadzirwa kuti mudziye zvinhu. Zvakasiyana nemishonga moto rinoshandiswawo kuzadza voids iri masonry uye chisimbiso slots mawindo.

tsananguro

Material kakawanda chinozoiswa dziri mabhanzi. It anogadzirwa muitiro kubvunda nesilicon oxides uye aruminiyamu panguva yakakwirira tembiricha iri rinokosha yamavira. Kaolin shinda kwemakore akawanda achishingaira kushandiswa nokuda kumbogadzirwa kuti mudziye zvivako uye outperforms zvimwe zvinhu zvizhinji. Pasinei ano-siyana nezvimwe yomuchipatara zvakafanana ehupfumi, zviri kuva akakurumbira zvikuru uye vakawana kushandiswa kwayo maindasitiri mafomu. It anoita somunhu kumbogadzirwa kuti mudziye mano, combustion makamuri, kupisa exchangers uye turbines. Inonyanya munyaya indasitiri. Uyewo kaolin shinda rinoshandiswa zvaAtemisi Slabs nezvimwe kuumbwa zvinhu.

The acho ane yakakwirira yakati inzwi nokupisa kuputira, kuramba deformation uye vibration zvinorema. Uyezve, donje ane zvimwe zvivako zviri yo nezvinhu zvizhinji akafanana chinangwa. The insulating zvinoreva haisi kukanganiswa yakakwirira tembiricha iri kwazvakarerekera kana oxidizing kwezvakatipoteredza, padanho kurwisa zvinogona yakawedzera nokushandisa chromium oxide. Pasinei neizvi, chikuru chikabviswa ndiko kuramba kupisa iri substantially wakaderedzwa ari kuderedza mhepo.

zvakwakanakira

Vata MKRR-130 rakanakira pakusikwa akamedura Mapedhi, kuputira anoita yamavira uye rusvingo zvakagadzirwa. Its Minimum uremu kunoderedza uwandu kwaida nguva uye kushanda kunodiwa kuti chokugadza kunoderedza huni mari. Zvinokosha kucherechedza zvimwe zvinhu zvakanaka:

• vakachenesa kwazvo fibers vanoonekwa ne mukuru kuramba devitrification;
• Minimum pamwero nokupisa kuwanda;
• kuramba chafariz kuvhunduka;
• Kuchengetedzwa yepakutanga zvatariswa panguva akadzokorora kushandiswa;
• refu dhigirii nokurira kuputira;
• Hazvina kukanganiswa hasha makemikoro, alkalis uye simbi inonyunguduka;
• inert kuti mafuta kwakavakirwa mafuta chicherwa, uye mvura mhute;
• nemagetsi Unhu kuramba kuchinja kunyange yakakwirira tembiricha.

Features

Kaolin shinda rakagadzirwa refractory alumina, iyo yakavakirwa Goldstone jecha. In rinokosha mhangura-simbi vira unonyauka panguva tembiricha kuti 1800 inegumi. In utsotso mapazi kupa electrodes matatu, panguva nzvimbo vezera ravo vari vaviri chete. ichivhuvhuta chidobi rinoshandiswa kuti kubvunda mashoko, inobva matambudziko ari chiutsi chaiyo inopiwa kuti kumanikidzwa vanenge 0,7 MPa. Ejection kamwene kunoita ndima dzose muchiridza muitiro. Sezvo binders anogona kuita mvura girazi, nevhu kana simende.

Vata kaolin inotengeswa mabhanzi anosvika 10 metres urefu, ukobvu uye upamhi 2 cm uye 60 cm azvaitwa. Hazvina kuchinja, nokudaro pave snug ikodzere chero zvakagadzirwa. Nhasi, vagadziri vari kuedza kuvandudza zvinhu kubudikidza kuwedzera mamwe zvinoriumba Somuenzaniso yttria. Izvi anovandudza kutsiga fibers uye kuwedzera kushandiswa kuita.

Zvinhu husingakwanisi nemoto

Refractory zvinhu yaigadzirwa chicherwa zvingoro uye husingakwanisi dzakakwirira tembiricha uye maitiro avo vanoramba kuchinja. Ivo inokosha zvikuru simbi indasitiri nokuda DISTILLATION, kugadzikana uye nemamwe maitiro, pakusikwa zvigadziriswe mukuru-tembiricha (Motors, reactors) uye zvinoumba kwavari. Pashure kushandisa refractories vanotumirwa kuti marara.

Kakawanda, kwakadai chigadzirwa ane rectangular chimiro uye pasi uremu, achivaita yakanaka siyana lining. Pari, pane rutapudzo nyore kugadzirwa refractories, sezvo pfungwa iri rwakabhadharwa kuna kugadzirwa dzinokosha mumaturi uye concretes, husingakwanisi yakakwirira tembiricha.

Refractory zvinhu: mukugadzira nzira

zvinhu Vane zvedongo chizvaro yakagadzirwa refractory borides, nitrides, oxides uye yakakwirira pamwero kwemakemikari inertness uye mukurumari. Uyewo aiwanzoshandisa kabhoni akakura. Refractory vaine ehupfumi dzavo kana apindwa tembiricha pakati 1600 madhigirii uye zvinoshandiswa dzakawanda kunodiwa kudiwa chero chinhu ari kupiwa ezvinhu. Maererano nzira rokuumba zvigadzirwa vari rakakamurwa marudzi akawanda:

• hot-kwazvo;
• chiwanikwa, kupatsanurwa kubva uchanyangadika;
• chikweshe Anoumba;
• chiwanikwa kwakavakirwa mvura penoshlikera;
• akatema kubva kupatsanurwa zvinogumbura kana matombo.
