How kuti refractory kongiri nemaoko avo?

Kuvaka Zvivako zvinangwa zvakasiyana kazhinji zvinoda kushandisa moto nemishonga zvinhu. Vanogona kushandiswa kudzivirira vanhu uye ezvirevo. Somumwe nezvinhu zvakadaro makabuda refractory kongiri. Vamwe dzakasiyana ayo anokwanisa kuwana kugara kutonhora kusvika 1000 ° C, uye chimiro uye anobatsira zvivako zviri vakaramba.

Key ehupfumi

Pakati huru zviri kongiri kwakadaro kunofanira pachena:

• mukuru refractoriness;
• kunowedzera waivako ehupfumi;
• simba;
• hapana vanofanira kushandisa inodhura. vachiridzira kwacho gadzira.

To musi, refractory kongiri inogona Classified kurema. Unozviita kana kuti inogona yakarondedzerwa zvinotevera mhando zvinhu:

• zvikuru kwazvo;
• nyore;
• yepasi;
• zvireme.

Somugumisiro, zvinhu zvinogona kutengwa chinogona kuita STRUCTURAL kana insulating kushanda kuti kunoenderana Zvinoumba chirungiso.

kugadzira zvinhu

Kana vakasarudza kuti refractory kongiri, chinofanira kuva vanyatsoona kwayo sezvamunoita. Material akaurayiwa pachishandiswa dzinokosha zvinoriumba uye vamwe yokuvirisa, pakati zviri:

• jecha Fireclay;
• magnesite;
• Siyana mhando muturunhuru ;
• aluminous simende.

Pakati yokuvirisa kuti vachiri govera chigayo pasi zvicherwa, aunopiwa zvinhu simba. Pakati yokuvirisa dzakadaro:

• pumice;
• nenguvo dzakarukwa zvakanaka zvakohwewa chromite mhangura;
• Nokufema nevira gang.

zvinoriumba aya vakawedzera kuwedzera arambe achirema kuti kwete rakapedzwa chigadzirwa asiwo yakaoma sezvamunoita. Dzimwe nguva, placeholders kwazvo mukugadzirwa akaita pasi chirimwa, asi mune zvimwe zviitiko angashandiswa refractory matombo uye kurwa vanogumurwa refractory zvidhina. Nokuti zvidzidzo siyana kongiri akawedzera aggregates kuti mapoka akasiyana. Kana iri nyaya vakasindimara, nezvekutanga angava dhayamita iri kuwanda 5 kusvika 25 mm. Kana totaura fines, ndicho panogumira 0,15 uye 5 mm. Pakati zvinhu izvi zvinofanira pachena:

• magnesite zvidhinha;
• fireclay pezvitinha;
• kurwa munhuwo chidhinha;
• aluminous gang;
• diabase;
• basalt;
• kwezvinoshandiswa Nokufema nevira gang.

Rakajairika pakati vatengi chinhu refractory kongiri, riri kugadzirwa kushandisa moto ivhu, nokuti ichiita zvose zvinodiwa kuvakwa. The aluminophosphate zvinhu uye mvura magirazi chiito ave mutauri. Portland, Magnesite uye aluminous cements , uye vave binders zvinoriumba. Kana zvokubikisa vari kuwedzera mvura girazi, unogona kuvandudza chokupika. Izvi ndezvechokwadi kunyanya kana chesamende kunovhengana rinoshandiswa vaumbe purasita rukoko.

Kuti uwane mazano pamusoro zvemichina

Refractory kongiri, murwiyo iyo inorondedzerwa munyaya, angava mumwe muchiso. Mumwe siyana kunoda kuwedzera ayo plasticizer, magnesite Nezvakakuyiwa uye ferrochromium gang. Kana uine chinangwa kugadzirira lightweight kongiri, unofanira kushandisa rakawedzerwa zvinhu pamusoro mhando:

• vermiculite;
• rakawedzerwa ivhu;
• perlite.

Kana ukasarudza arayire kugadzirwa musanganiswa kubva nyanzvi, nhamba zvakamisa hurongwa, ivo Muchazvinhonga pachavo, maererano ramunoda. The sezvamunoita anosarudzwa maererano operative tembiricha uye basa ezvinhu.

Uyewo, Kuronga mhando filler

Kana ukasarudza kuita refractory kongiri namaoko avo, ipapo iwe fillers akasiyana zvinogona kushandiswa, zvinoti:

• dinas;
• corundum;
• Goldstone;
• vakagadzirira mixes.

Kufunga chesamende nziyo, anoratidza muchiso. Somuenzaniso, ASBG chakaoma refractory aruminiyamu tubhokisi nezvakavhenganiswa, iro rinoshandiswa ferrous uye nonferrous simbi uye chafariz simba. High-alumina kongiri pamwe refractory zvivako rakapfupikiswa VGBS uye akaronga kuti pave monolithic lining kuti vachikanda yendiro, masvingo uye pazasi mudziyo.

sezvamunoita kwakadaro kungashandiswa pane kutonhora kusvika 1800 ° C. Unowedzera muvhenganiswa inopisa mukuru-Saba akasarudzwa nemabhii. Mwari akaronga kuti chafariz dzakabatana, yamavira uye midziyo yacho anowedzera rukoko. Kusangana tembiricha inogona kusvika padanho 750 ° C.

Screed

Kuomesa pakati refractory kongiri kunogona kuitwa pashure okuguma koukukutu danho. Muchiitiko ichi mhepo rinoshandiswa uye ambient kupisa hakufaniri yakaderera pane +10 ° C. Pamberi kwokutanga kudziyisa kongiri inofanira kuchengetwa kuti zuva kana kupfuura kuti vabudirire vachiwana mamiriro. nokuomesa oparesheni kunoita kuderedza huwandu vakasununguka mvura kongiri, izvo zvaizoita kuti makemikari maitiro pakati zvomumhepo uye pechiso lining.

Mushure achirapa liner akasiiwa ane nyorovera mhepo pasina kuomesa. Pashure Kurapwa zvakakwana kuva yakaoma lining. Kana zvisingaiti, chesamende akasiiwa ane namahwindo nyorovera ezvinhu. Zvakakosha kuti pave kufefetedza akanaka kana kusiya liner ari zvakanaka ventilated nzvimbo. Kana uri kushamisika sei kuti refractory kongiri, vanofanira kuva aiziva zvinhu uye kunyange kuigadzira kuti kushanda. Somuenzaniso, kuomesa danho anogona kutora nzvimbo uchishandisa akakodzera rusero kana blower, izvo achakupaiwo mhepo inopisa.

Features akanya

Usati kuita refractory kongiri namaoko avo, murwiyo chemhinduro anofanira vanyatsohuongorora akasarudzwa. Izvi chakataurwa pamusoro. Kana zvinoitwa vaiitawo, zvino inokurudzirwa kushandisa chovha. Zviri nani kuti kupisa-insulating kongiri, asi kuti hwakasimba zvingaitwa uye zvachose zvakakodzera, sezvo anobvumira kusanganisa noruvara uye nemazvo zvinhu pamwe kuwedzera zvishoma mvura. Maererano samende chisanganiso, ipapo mugumisiro uchava zvakaoma chaizvo kuti kuzadzisa.

rutsigiro ichi rinoshanda uyewo nokuti, nokuda gobvu kongiri mwando kugutsikana kunogona kutsoropodza. Pashure pezvose, nokuti zvinorondedzerwa zvinhu nesimba kunonyanyisa kunodiwa, pamwe Zvakanyanya Kunaka Panguva Yepamuviri arambe achirema. By hunhu hwavo, insulating kongiri ari manyoro kupfuura rizere, saka zvakakosha kuti vari yakakanyiwa runodiwa huwandu mvura. nekumwisa Its kunogona kukonzera kuderera simba uye arambe achirema, asi kushayikwa achaita vasanyanye goho.

The kukura refractory kongiri

Kugadzirira refractory kongiri inofanira kuitwa achiita zvaidiwa zvimwe zvikuru. Kana kushandisa zvinhu aronga kuvaka moto, zvino pashure solidifying mumushonga vanofanira kukwanisa kutsungirira tembiricha iri kuwanda 1200 ° C. Kubva musanganiswa inogona kuitwa choto uye firebox. Nokuti basa vachada kuva chesamende part 1 M-400, 2 mativi jecha kubva refractory nezvidhinha, chete mativi hondo zvidhina mafufu, uye 0.33 chikamu chamotte guruva chirungiso.

Kana uri kuronga kuvaka hwakasimba pakati, ipapo paari panguva nokushanda kudziyisa michina huchachinja pachena murazvo kuva zvechigarire. Izvi zvinoda kugadzirira mhinduro pamwe anotevera kukura: 2,5 zvikamu yakapwanyika ibwe, kongiri chikamu, 0.33 chikamu chamotte jecha. Kana marara, zvinogona kuitwa Goldstone kana tsvuku chidhinha, neimwe nzira dzimwe nguva rinoshandiswa chigayo pasi chidhinha dzvuku.

mhedziso

Properties ane mhinduro kusika munhu refractory kongiri zvakafanana nezvaishandiswa mune kwakajairika simende slurry vaiitawo. Kana ukaguta kuitwa vakapinda formwork, rakaramba inofanira kuendeswa Kutenderera. Dzimwe nguva zvinhu zvinoshandiswa yokuva zvitarisiko kubva plywood.

Kuti tidzivise kwemvura mvura panguva solidification, chacho pashure kugadzirwa anofanira chisimbiso. Izvi hwezvekukurukurirana nyore kubviswa castings. Nyore nzira kunama - polyethylene, asi kuitira kuti awane migumisiro yakanakisisa, unofanira kushandisa silicone, ndiro pre-lubricated mafuta muriwo.
