Chii chinonzi Refractory Bricks?

Refractory brickchinhu checeramic chinowanzo shandiswa munzvimbo dzakanyanya kupisa nekuda kwekushaikwa kwekupisa uye nekuti insulator yakanaka inoderedza kurasikirwa kwesimba. Refractory brick inowanzo umbwa nealuminium oxide uye silicon dioxide. Inonzi zvakare "chidhinha chemoto."

Kuumbwa kweRefractory Clay

Refractory ivhuinofanira kunge iine chikamu chepamusoro che "isina ngozi" silicon dioxide uyealuminiumoxide. Vanofanira kunge vane zvimedu zvidiki zvekukuvadza lime, magnesium oxide, iron oxide, uye alkali.
Silicon Dioxide: Silicon dioxide (SiO2) inopfava inosvika 2800 ℉ uye pakupedzisira inonyunguduka yoshanduka kuita chinhu chegirazi panenge 3200 ℉. Inonyungudika inosvika 3300 ℉. Iyi yakakwirira kupfava uye kunyungudika inoita kuti ive chinhu chikuru chekugadzira zvidhinha zvinoramba.
Alumina: Alumina (Al2O3) ine yakanyanya kupfava uye kunyunguduka tembiricha kupfuura silicon dioxide. Inonyungudika inosvika 3800 ℉. Nokudaro, inoshandiswa pamwe chete nesilicon dioxide.
Lime, magnesium oxide, iron oxide, uye alkali: Kuvapo kwezvinhu izvi zvinokuvadza kunobatsira kuderedza kunyorova uye kunyungudika tembiricha.

Zvinhu Zvikuru zveRefractory Bricks

Refractory bricks kazhinji ane yellowish-white muruvara
Ivo vane yakanakisa kupisa kupisa uye yakakura yekumanikidza simba
Mushonga wavo wekemikari wakasiyana chaizvo neyezvidhinha zvenguva dzose
Zvidhinha zvinoramba zvine 25 kusvika 30% alumina uye 60 kusvika 70% silica.
Izvo zvinewo ma oxides e magnesium, calcium, uye potassium
Refractory zvidhinhainogona kushandiswa kugadzira kilns, mavira, nezvimwe.
Vanokwanisa kumira tembiricha kusvika 2100 degrees Celsius
Ivo vane zvinoshamisa kupisa kugona izvo zvinobatsira zvimiro zvakasiyana kuti zvirambe zvakatsiga mukupisa kwakanyanya.

Kugadzira nzira yezvidhinha zvinoramba

Zvidhinha zvemoto zvinogadzirwa nenzira dzakasiyana-siyana dzekugadzira zvidhinha, sekukanda madhaka akapfava, kudzvanya kupisa, uye kuomesa. Zvichienderana nezvinhu zvezvidhinha zvemoto, mamwe maitiro achashanda zviri nani pane mamwe. Zvidhinha zvemoto zvinowanzoumbwa kuita rectangular chimiro chine zviyero zve 9 inches kureba × 4 inches yakafara (22.8 cm × 10.1 cm) uye ukobvu pakati pe 1 inch uye 3 inches (2.5 cm kusvika 7.6 cm).

Kugadzirira kwezvinhu:
Refractory zvinhu: Zvakajairwa mbishi zvinhu zvinosanganisira alumina, aruminiyamu silicate, magnesium oxide, silica, etc. Izvi mbishi zvinhu zvakaganhurwa zvichienderana nezvinodiwa uye mhando.
Binder: Ivhu, gypsum, nezvimwewo zvinowanzo shandiswa sebhainda kubatsira zvidimbu zvenyama kusanganisa nekuumba.
Kusanganisa uye kugaya:
Isa zvinhu zvakagadzirirwa zvakagadzirirwa mumudziyo wekuvhenganisa wekuvhenganisa nekusanganisa kuti uve nechokwadi chekuti zvakasiyana siyana zvakasanganiswa zvakasanganiswa uye zvakaenzana.
Mishonga yakasanganiswa inogayiwa zvakanaka kuburikidza neguyo kuita kuti zvidimbu zviwedzere kufanana uye zvakanaka.
Kuumba:
Iyo yakasanganiswa uye pasi mbishi zvinhu zvinoiswa mu mold mold uye inoumbwa kuita chimiro chezvidhinha kuburikidza nevibration compaction kana extrusion molding.
Kuomesa:
Mushure mekugadzira, zvidhinha zvinoda kuomeswa, kazhinji nekuomeswa kwemhepo kana kuomeswa muimba yekuomesa, kubvisa unyoro kubva pazvidhinha.
Sintering:
Mushure mekuoma, zvidhinha zvinoiswa mune refractory zvidhinha uye sintered at high temperatures to burn out the binder in the raw materials and kubatanidza zvimedu kuti zvigadzire chimiro chakasimba.
Iyo tembiricha yekupisa uye nguva inosiyana zvichienderana neyakasiyana mbichana uye zvinodiwa, uye kazhinji inoitwa pasi petembiricha yepamusoro inopfuura 1500 ° C.

Zvakanakira Kushandisa Refractory Bricks kana Fire Bricks

Kushandisarefractory zvidhinhainopa toni yezvakanakira. Izvo zvinodhura kupfuura zvidhinha zvakajairika nekuda kwekusiyana kwavo kwepamusoro-yekupedzisira insulating kugona. Nekudaro, ivo vanopa mamwe akasiyana mabhenefiti mukutsinhana nekuwedzera mari yako. Basic Refractory Bricks Suppliers muIndia zvakare vanovimbisa kuwanikwa kweMagnesia Bricks munyika uye vanopa zvidhinha zvinoramba zvichiva nezvakanakira zvinotevera:

Yakanakisa Insulation
Refractory zvidhinha zvinonyanya kushandiswa kune yavo incredible insulating properties. Vanovhara kupinda kwekupisa. Vanochengetawo chimiro chakasununguka zvose muzhizha uye munguva yechando.

Zvakasimba Kupfuura Zvidhinha Zvenguva Dzose

Refractory zvidhinha zvakasimba kudarika zvidhinha zvemazuva ose. Ndokusaka akasimba kupfuura zvidhinha zvenguva dzose. Ivowo zvinoshamisa lightweight.

Chero Chimiro uye Saizi
Basic Refractory Bricks Suppliers muIndia zvakare vanovimbisa kuwanikwa kweMagnesia Bricks munyika uye vanopa customizable refractory zvidhinha. Vazhinji vagadziri uye vatengesi vanopa zvidhinha zvakagadzirirwa muhukuru hunodiwa uye zviyero kune vatengi.

Chii chinonzi Refractory Bricks Chinoshandiswa?

Refractory zvidhinhatsvaga kushandiswa munzvimbo dzinopisa kupisa kwakakosha. Uyu muenzaniso unosanganisira mavira. Iwo akanakira kunenge ese akanyanyisa mamiriro ekunze. Vagadziri vakawanda vanozivikanwa vanotoshandisa zvidhinha izvi mumabasa ekuvaka dzimba. Mumamiriro ekupisa, zvidhinha zvinoramba zvichichengetedza mukati kutonhorera uye kutonhora kure. Vanochengetawo imba ichidziya.
Pamidziyo yemumba, yakadai sehovhoni, magrills, uye moto, zvidhinha zvinoramba zvichishandiswa zvinowanzogadzirwa nevhu rine kunyanya aluminium oxide nesilicon dioxide, zvinhu zvinokwanisa kutsungirira kupisa kwakanyanya. Aluminium oxide ine zvinoratidzira zvimiro, nepo silicon dioxide iri yakanakisa insulator. Iyo yakawanda aluminium oxide iripo mumusanganiswa, iyo yakakwirira tembiricha iyo zvidhinha inogona kumira (yakakosha kufunga nezvekushandiswa kwemaindasitiri) uye iyo inodhura iyo zvidhinha ichave. Silicon dioxide ine grey color, ukuwo aluminium oxide ine ruvara rweyero.

Zvinogara zvakakosha kusimbisa kuti pakugadzira kana kuvaka zvivakwa zvinosangana nemoto, unofanirwa kutarisisa kana zvinhu zvinoshandiswa zvinoenderana nemitemo yenzvimbo. Uyu mutengo muduku kubhadhara kuti udzivise kurasikirwa kwezvinhu kana dzimwe njodzi dzakakomba. Zvinogara zvichidikanwa kutsvaga mazano kubva kune nyanzvi nevagadziri.
