Tichitora girazi rinoyangarara semuenzaniso, iwo matatu makuru ekudziya ekugadzira magirazi anosanganisira anoyangarara girazi rekunyungudusa, girazi regirazi rekugezera uye girazi rinopisa moto. Mukugadzira girazi rekugadzira, girazi rinonyungudusa muvira rinoita basa rekunyungudutsa zvinhu zvebatch mugirazi remvura uye kujekesa, homogenizing uye kutonhora kune tembiricha inodiwa pakuumbwa. Iyo tin yekugezera ndiyo yakakosha midziyo yekuumba girazi. Iyo girazi mvura ine tembiricha ye1050 ~ 1100 ℃ inoyerera ichibva mugero yekuyerera ichienda kune emarata emvura pamusoro mubhavhu rerata. Mvura yegirazi inopepetwa uye kukwenenzverwa pamusoro pebhati rekugezera retani, uye inodzorwa nekudhonzwa kwemuchina, varindi vepadivi nemichina yekudhirowa padivi kuita ribhoni regirazi rehupamhi hunodiwa uye ukobvu. Uye inosiya bhati remarata painotonhora zvishoma nezvishoma kusvika 600 ℃ panguva yekuenderera mberi. Basa rechoto che annealing nderokubvisa kushushikana kwakasara uye optical inhomogeneity yegirazi rinoyangarara, uye kudzikamisa chimiro chemukati chegirazi. Ribhoni yegirazi inoenderera ine tembiricha ingangoita 600 ℃ yakakonzerwa nebhati yekugezesa inopinda muchoto chinopinza kuburikidza neshanduko roller tafura. Ese aya matatu makuru emidziyo yekupisa inoda refractory zvinhu. Kuti ave nechokwadi chekushanda kwakajairika uye kwakagadzikana kushanda kwegirazi yekunyunguduka kwevira, zvechokwadi haiparadzaniswi kubva pakutsigirwa kwezvinhu zvakasiyana-siyana zvinoramba. Aya anotevera marudzi 9 ezvigadzirwa zvekuramba zvinowanzoshandiswa mumagirazi ekunyungudutsa mavira uye maitiro avo:
Silika zvidhinha zvegirazi kilns:
Mishonga mikuru: silicon dioxide (SiO2), zvirimo zvinofanirwa kuve pamusoro pe94%. Kushanda tembiricha: yakanyanya tembiricha yekushandisa ndeye 1600 ~ 1650 ℃. Zvimiro: kupikisa kwakanaka kune acidic slag erosion, asi kushomeka kuramba kune alkaline inobhururuka kukukurwa kwezvinhu. Inonyanya kushandiswa kugadzira mabheji makuru, madziro ezamu uye mavhiri madiki.
Fire Clay zvidhinha zvegirazi kilns:
Zvinonyanya kukosha: Al2O3 uye SiO2, Al2O3 zvinyorwa zviri pakati pe30% ~ 45%, SiO2 iri pakati pe51% ~ 66%. Kushanda tembiricha: yakanyanya tembiricha yekushandisa ndeye 1350 ~ 1500 ℃. Zvimiro: Iyo isina kusimba acidic refractory zvinhu ine yakanaka refractoriness, kugadzikana kwekupisa uye kuderera kwekushisa conductivity. Inonyanya kushandiswa pakugadzira pasi pechidziva chemoto, dziva remadziro echikamu chekushanda uye nzira, rusvingo, arch, yezasi cheki zvidhinha uye flue yekamuri yekuchengetera kupisa.
High alumina zvidhinha zvegirazi kilns:
Zvikamu zvikuru: SiO2 uye Al2O3, asi zvinyorwa zveAl2O3 zvinofanira kunge zvakakura kudarika 46%. Kushanda tembiricha: Iyo yakanyanya tembiricha yekushandisa ndeye 1500 ~ 1650 ℃. Zvimiro: Yakanaka corrosion kuramba, uye inogona kuramba ngura kubva kune ese acidic uye alkaline slags. Inonyanya kushandiswa mumakamuri ekuchengetera kupisa, pamwe chete nemidziyo inodzivirira yemadziva ekushanda, zviteshi zvezvinhu uye mafidhi.
Mullite zvidhinha:
Chinhu chikuru chemullite zvidhinha ndeyeAl2O3, uye zvinyorwa zvayo zvinenge 75%. Nekuda kwekuti inonyanya kuita mullite crystals, inonzi mullite zvidhinha. Density 2.7-3 2g/cm3, yakavhurika porosity 1% -12%, uye yakanyanya tembiricha yekushandisa i1500 ~ 1700 ℃. Sintered mullite inonyanya kushandiswa kugadzira masonry emadziro emakamuri ekuchengetedza kupisa. Fused mullite inonyanya kushandiswa kugadzira masonry emadziro emadziva, maburi ekutarisa, madziro buttresses, nezvimwe.
Fused zirconium corundum zvidhinha:
Fused zirconium corundum zvidhinha zvinonziwo zvidhinha zvesimbi zvichena. Kazhinji, yakasanganiswa zirconium corundum zvidhinha zvakakamurwa kuita mamakisi matatu maererano ne zirconium zvirimo: 33%, 36%, uye 41%. Iyo zirconium corundum zvidhinha inoshandiswa muindasitiri yegirazi ine 50% ~ 70% Al2O3 uye 20% ~ 40% ZrO2. Density ndeye 3.4 ~ 4.0g/cm3, iyo inooneka porosity i1% ~ 10%, uye yakanyanya tembiricha yekushanda inosvika 1700 ℃. Yakasanganiswa zirconium corundum zvidhinha zvine zirconium ye33% uye 36% inoshandiswa kuvaka honi dziva madziro, murazvo nzvimbo yemazamu madziro, madiki madiki echoto anoputika maburi, madiki echoto akadzikama arches, madiki echoto mashefu, rurimi arches, nezvimwe. makomba, uye zvimwe zvikamu apo mvura yegirazi inoparadza uye inoparadza zvinhu zvinoramba zvine chisimba. Nyaya iyi ndiyo inonyanya kushandiswa fused cast refractory zvinhu muindasitiri yegirazi.
Fused alumina zvidhinha:
Inonyanya kureva yakasanganiswa α, β corundum, uye yakasanganiswa β corundum refractory zvidhinha, izvo zvinonyanya kuumbwa ne92% ~ 94% Al2O3 corundum crystal phase, density 2.9 ~ 3.05g/cm3, inooneka porosity 1% ~ 10% tembiricha yekushanda inosvika 170% tembiricha. Fused alumina ine yakanakisa kuramba kune girazi permeation uye inenge isina kusvibiswa kumvura yegirazi. Iyo inoshandiswa zvakanyanya muchikamu chekushanda chedziva madziro, dziva rezasi, kuyerera chiteshi, kushanda chikamu chemidziyo chiteshi chedziva madziro, zvinhu chiteshi dziva pazasi uye zvimwe zvikamu zvegirazi rinonyungudusa choto chinobata mvura yegirazi uye chisingadi kusvibiswa kunopesana.
Zvidhinha zvequartz:
Chinhu chikuru iSiO2, ine zvinopfuura 99%, ine density ye1.9 ~ 2g/cm3, refractoriness ye1650 ℃, tembiricha yekushanda ingangoita 1600 ℃, uye asidi erosion resistance. Inoshandiswa kuvaka dziva madziro eacidic boron girazi, flame space thermocouple hole zvidhinha, nezvimwe.
Alkaline refractory zvinhu:
Alkaline refractory zvinhu zvinonyanya kureva magnesia zvidhinha, alumina-magnesia zvidhinha, magnesia-chrome zvidhinha, uye forsterite zvidhinha. Kuita kwaro ndekwekuramba kukukurwa kwezvinhu zvealkaline, uye refractoriness yayo ndeye 1900 ~ 2000 ℃. Inoshandiswa zvakanyanya mumadziro ekumusoro kweiyo regenerator yegirazi yakanyunguduka choto, iyo regenerator arch, iyo grid body, uye diki chevira chikamu chimiro.
Insulation zvidhinha zvegirazi furnaces:
Iyo nzvimbo yekupisa yekupisa yegirazi yekunyunguduka yevira yakakura uye kugona kwekupisa kwakadzikira. Kuti uchengetedze simba uye uderedze kushandiswa, huwandu hukuru hwezvinhu zvekudzivirira hunodiwa kuti uwedzere kuvharisa. Kunyanya, dziva rusvingo, dziva pasi, arch, uye rusvingo mune regenerator, kunyunguduka chikamu, kushanda chikamu, etc. anofanira insulated kuderedza kupisa dissipation. Iyo porosity yechidhinha chekudzivirira yakakura kwazvo, uremu hwakareruka, uye density haipfuure 1.3g/cm3. Sezvo kupisa kwekushisa kwekuita kwemhepo kwakashata zvikuru, chidhinha chekudzivirira chine porosity yakakura ine insulating effect. Iyo yekupisa kwayo conductivity coefficient yakadzikira 2 ~ 3 nguva yakaderera pane iyo yeyakajairwa refractory zvinhu, saka iyo yakakura iyo porosity, zviri nani iyo insulation mhedzisiro. Kune akawanda akasiyana marudzi ezvidhinha zvekuvharisa, anosanganisira ivhu rekudzivirira zvidhinha, silica insulation zvidhinha, yakakwirira alumina insulation zvidhinha uye zvichingodaro.
