Iyo huru yekupisa yemidziyo yekugadzira girazi, senge fusing density, vaviri groove, nzira yekudyisa uye annealing density, inonyanya kugadzirwa nezvinhu zvinoramba.tIye sevhisi inoshanda uye hupenyu hwesevhisi yemidziyo uye kunaka kwegirazi kunoenderana nerudzi uye mhando yezvidziviriro zvinoshandiswa.tkufambira mberi kwetekinoroji yekugadzira kunoenderana nekuvandudzwa kweiyo refractory yekugadzira tekinoroji uye mhando kusvika pamwero mukuru. Naizvozvo, zvinodikanwa kusarudza zvine musoro uye kugadzirait inonyanya kukosha kushandisa refractories mukugadzira uye kushanda kwemazuva ese kwegirazi rinopisa michinatiye wechipiri ndiyo mamiriro ebasa uye corrosion mechanism yezvikamu zvakasiyana zvemidziyo yekupisafire zvinhu zvinoreva inorganic nonmetallic zvinhu kana zvigadzirwa zvine moto kuramba zvisingasviki 1500 ℃ (1580 ℃ muChina uye yaimbova Soviet Union)it inogona kuve yakasikwa zvigadzirwa, zvakare inogona kuve yakagadzirwa nevanhu zvigadzirwa uye zvinhu, refractories mukuwedzera kune imwe nhanho yekudzivirira moto, asi zvakare inofanirwa kuve nekugona
Main technical performance yehurongwa:
① Kuti isangane nezvinodiwa zvekushanda kwekushisa kwepamusoro, haifanire kupfava uye kunyungudika pakupisa kwakakwana;
② Inogona kutakura mutoro wechoto uye kushushikana mukati mekushanda, uye kutakura kumwe kudzvinyirira kwakashata pakupisa kwakanyanya.;
Iko hakuna kurasikirwa kwesimba rekugadzirisa, deformation uye kukundikana;
③ Yakakwira tembiricha vhoriyamu kugadzikana haigone kuburitsa mumvuri wakawandisa kana shrinkage, gobvu rechoto masonry kana kudira muviri hauzodzike nekuda kwekuwedzera kwevhoriyamu.emakatsemuka kana makatsemuka aripo;
④ Thermal shock resistance haiputsi pasi peimwe tembiricha mutsauko uye kuvhunduka kwekushisa;
⑤ Iyo anti invasion performance inogona kumira kwenguva refu kuita kwegasi, mvura uye yakasimba corrosive medium pasina kukurumidza kukukurwa, uye inogona kumira mukuora.okuderedzwa kwe xidation pakupisa kwakanyanyaitinogona kumira nekugona kwekushisa kwepamusoro uye nekumhanya kwakanyanya kuyerera murazvo uye utsi, kukukurwa kwesimbi yemvura uye slag, pamwe nekudonha kwekumanikidza.ikukuya kwesimbi nezvimwe zvinhu;
② Iko kupisa kwekuongorora kwekupisa kwekupisa uye zvimiro zvakasara zvivakwa zvinoreva kutsemuka uye kuyedzwa kudonha kwemuviri wezvidhinha kunokonzerwa nekushanduka kwekushisa. Chimiro.
Kudonha kunoreva chokwadi chekuti kunyunguduka kwezvidhinha kunopinda muchidhinha pamwe nemapores ayo uye nzira dzekutsemuka, uye kupindirana nacho kugadzira chimiro chakafanana neicho chepakutanga..
Kana tembiricha yachinja zvakanyanya, iyo metamorphic layer ine akasiyana zvidhinha chimiro uye zvivakwa zvinotsemuka nekudonha.
Indasitiri yegirazi yakasarudzika pakuti chikamu chakakukurwa chegirazi dense sulfur muviri ucharamba uri mugirazi remvura kana ichigona kunyungudika zvachose..
Mugirazi, kuumbwa kwegirazi kunongokanganiswa zvishoma, izvo zvisingakuvadzi kune rimwe girazi, asi kwete kune rimwe girazi rinokosha..
Xu: kana isingakwanise kunyungudika zvachose, nhevedzano yemagirazi akaremara sematombo, nodules uye mabhubhu achaumbwa, zvichikonzera marara. Rimwe divi.
Parizvino, hupenyu hwesevhisi yegirazi huru yekuyangarara yeChina yasvika makore makumi mashanu.
Anopfuura makore 8, asi pachine mukaha mukuru kana uchienzaniswa nenyika dzine indasitiri yegirazi yakagadziridzwa. Nokudaro, hutano hwe refractory ndiyo kiyi yehutano hwegirazi.
Zvinhu zvakakosha zvekusimudzira maindasitiri
Hunhu hwerefractories yegirazi choto
Refractories iboka re multiphase uye multicomponent yakaoma masisitimu, ayo anoumbwa neakasiyana akasiyana emakemikari ekuumbwa uye zvicherwa zvine akasiyana zvimiro.
Plastid. Izvo zvimiro zve refractories zvine hukama zvakanyanya kune yavo makemikari kuumbwa, chikamu kuumbwa, bonding morphology uye kugovera, pamwe nehunhu hwechikamu chimwe nechimwe.
makemikari anoumbwa
Mushonga wemakemikari we refractories ndechimwe chezvinhu zvinokosha zvinotarisa maitiro e refractories.Kemikemikari ye refractories inogona kupatsanurwa muzvikamu zviviri maererano nekuumbwa uye basa: chikamu chikuru chinoverengera huwandu hukuru uye chinotamba sarudzo. basa mukuita kwayo, uye chikamu chidiki chinoverengera chitsama chidiki chinonzi chikamu chechipiri. Chikamu chechipiri chinosanganisira chikamu chekusachena chinoperekedza zvinhu zvakasvibiswa uye chikamu chekuwedzera chakawedzerwa kuzadzisa chimwe chinangwa.
(1) Chikamu chikuru chikamu chikuru kuumbwa kwenguva yemoto matrix mune refractories, iyo inowanzova imwe kana akati wandei emhando dzakanyanya kunyunguduka ignition oxides kana asiri oxides anoumbwa neakasanganiswa zvicherwa. Kuita kwayo uye kuwanda kwaro kunotarisisa zvimiro zvenguva yemoto zvinhu. Nguva yemoto zvinhu zvinogona kukamurwa kuita asidhi, alkaline uye isina kwayakarerekera zvinoenderana nemakemikari avo.
(2) Chikamu chekusachena chinoreva zvinhu zvinoramba zvinounzwa kana kusanganiswa mukugadzira nekuda kwekushandiswa kwechisikigo chicherwa.
Kazhinji kutaura, Ko, Nao, FeO uye FeO zvinhu zvemoto zvenguva
Izvo zvinokuvadza tsvina muchigadzirwa. Pamusoro pezvo, iyo acid oxide (ro2) uye acid oxide mune yakakosha pyrotechnic zvinhu (RO ndiyo chikamu chikuru) inowedzerwawo.
Iyo okisijeni mumidziyo yepyrotechnic inoonekwa sezvikamu zvinokuvadza, zvine solvation yakasimba pakupisa kwakanyanya. Mhedzisiro yacho haisi pachena
Iyo chete tembiricha yekuumbwa ye eutectic fluid chikamu inoderera uye huwandu hwemvura chikamu hunowedzera, uye nekuwedzera kwekushisa, huwandu hwechikamu chemvura hunoderera.
Iyo inowedzera kumhanya inokwidziridzwa, iyo inokanganisa zvakanyanya kupisa kwekushisa kwezvigadzirwa zve refractory. Nokudaro, zvinodikanwa kudzora kuumbwa kwekusachena kwakaderera sezvinobvira
Semuenzaniso, chikamu chikuru chesilica brick iSiO, uye zvinokuvadza zvinosanganisira Ao, kune uye alkali metal oxides. American Standard
Izvo zvinodikanwa kuti iyo yakazara yemukati yetsvina mune yakakosha giredhi silicon breaker isingasviki 0.5%, uye zvirimo muAo muBritish standard silicon breaker i0.3%
Kune marudzi maviri ekuyerera mhedzisiro yetsvina mune refractories ine zviri mukati a1o isingasviki 0.6%
(1)Nekuda kwekuita kwemakemikari, yakaderera kunyungudika mvura chikamu chinoumbwa;(2)Chikamu chemvura chakaumbwa patembiricha imwechete haireve kuti yakaderera kunyungudikalarge quantity.
(3) Kuti uvandudze mashandiro emuviri, kugadzirwa kwekuita uye kushanda kweiyo refractory, kuwedzera kwemakemikari anoumbwa mukugadzira kana kushandiswa kwekuramba..
Chinhu chiduku chekuwedzera chinogona kuwedzerwa kuvandudza kushanda kwechigadzirwa chinonzi additive. Iyo dosage yezvinowedzera inosiyana nemaitiro avo uye mabasa, uye kazhinji yakaderera.
Izvo zvishoma zviuru gumi kusvika kune zvishoma muzana zvehuwandu hwekuumbwa kwezvinhu zvepyrotechnic. Additives inogona kukamurwa muzvikamu zvinotevera zvichienderana nezvinangwa zvavo uye mabasa:
(1）Nguva yemoto zvinhu zvakaunganidzwa zvinosunga kuita kirasi: binder, inozivikanwawo sesementing agent kana kumira mumiriri;(2）gadzirisa marongero uye kuomesa chiyero kirasi: kusanganisira inomhanyisa mumiriri, polar mumiriri uye zvichingodaro;(3）shandura iyo rheological properties: kusanganisira mvura inoderedza, plasticizer, gelling agent uye degumming agent, nezvimwewo;(4）Gadzirisa sangano remukati Chimiro kirasi: inosanganisira furo agent, defoamer, shrinkable agent, kuzvimba agent, nezvimwewo;(5）kuvandudza durability kirasi: kusanganisira inhibitor, kuchengetedza, anti kuzvimba agent, etc Cryoprotectants, nezvimwe; Kuvandudza mashandiro, kusanganisira sintering aid, mineralizer, fast drying agent, stabilizer, etc. Hydration resistance; Antioxidant, anti reducing agent, etc..
Kune akawanda marudzi ekuwedzera, ayo ari akakosha ekutsvagisa zvinhu muindasitiri yemidziyo yemoto
Zvishoma: 2. Inogona kuchinja zviri pachena mamwe mabasa kana maitiro ezvigadzirwa zvinoramba; 3. Haina kukanganisa kwakakomba pane zvakakosha zvezvigadzirwa, zvakadai sekugadzirwa kwesilika zvidhinha.
Kuwedzerwa kwemukaka we lime uye iron ndeye mineralizer kufambisa kuumbwa kwequartz; Cao yakawedzerwa kune chigadzirwa ndeye stabilizer kuita kuti chigadzirwa chigadzikane.
Mhedzisiro yacho inoratidza kuti cubic ZrO 2 inoumbwa pakupisa kwepamusoro inogadzikana pakudziya kwakadzika: MgO nezvimwe zvinowedzera mukuchena kwakanyanya Al 2O ceramics vari sintering aids.high density sinter inogona kuwanikwa pane yakaderera tembiricha.
