Yepamusoro tembiricha inodzivirira refractory zvidhinha zveKilns, furnaces
Zvinoenderana nezvikamu zvakasiyana zvezvidhinha zvinoramba, zvinogona kukamurwa kuita zvikamu zvishanu, zvinoti: silicon-alumina series refractory bricks, alkaline series refractory bricks, carbon-containing refractory bricks, zirconium-containing refractory bricks, uye zvidhinha zvinopisa zvinopisa.
Chero choto hachina kuvakwa nemhando imwe chete yezvidhinha zvinoramba, inoda musanganiswa wezvidhinha zvakasiyana zvinoramba.
(1)Sirika zvidhinha zvinoreva zvidhinha zvinoramba zvine zvinopfuura 93% SiO2, ayo ndiwo makuru emhando yeasidhi refractory zvidhinha.Iyo inonyanya kushandiswa kugadzira coke oveni, asiwo kune mavhavha uye zvimwe zvinotakura-zvinotakura zvikamu zvemafuta ekupisa emhando dzakasiyana dzegirazi, ceramics, kabhoni calciners, uye zvidhinha zvinoramba.Inoshandiswa mumidziyo inopisa iri pasi pe600 ° C uye nekuchinja kukuru kwekushisa.
(2)Zvidhinha zvevhu.Zvidhinha zvevhu zvinonyanya kuumbwa nemullite (25% kusvika 50%), girazi chikamu (25% kusvika 60%), uye cristobalite uye quartz (kusvika 30%).Kazhinji, ivhu rakaoma rinoshandiswa seyakabikwa, clinker inoverengerwa pachine nguva uye yozosanganiswa nevhu rakapfava.Magirazi mashoma emvura, simende, uye mamwe mabhanhire anogonawo kuwedzerwa kugadzira zvigadzirwa zvisina kupiswa uye zvinhu zvisina kuumbwa.Ichi chidhinha chinowanzo shandiswa chidhinha mumavira anoputika, zvitofu zvinopisa, zvitofu zvekudziisa, mabhoiler emagetsi, kilns yeraimu, kilns inotenderera, ceramics, uye zvidhinha zvinopisa zvidhinha.
(3) High-alumina refractory zvidhinha.Iko kuumbwa kwemaminerari e-high-alumina refractory zvidhinha ndeye corundum, mullite, uye girazi zvikamu.Izvo zvigadzirwa zvakakwirira-alumina bauxite uye sillimanite zvakasikwa ore, uye kune zvakare yakasanganiswa corundum, sintered alumina, synthetic mullite, uye clinker calcined nealuminium uye ivhu muzvikamu zvakasiyana.Iyo inonyanya kugadzirwa nenzira ye sintering.Asi zvigadzirwa zvinosanganisira zvidhinha zvakasanganiswa, zvidhinha zvakasanganiswa, zvidhinha zvisina kupiswa, uye zvidhinha zvisina kuumbwa.High alumina refractory zvidhinha anoshandiswa zvakanyanya musimbi nesimbi indasitiri, isiri-ferrous simbi indasitiri, uye mamwe maindasitiri.(4) Corundum refractory zvidhinha, corundum zvidhinha zvinoreva rudzi rwezvidhinha zvinoramba zvine AL2O3 zvemukati zvisingasviki 90% uye corundum sechikamu chikuru, chinogona kukamurwa kuita sintered corundum zvidhinha uye yakasanganiswa corundum zvidhinha (5) High- alumina heat-insulating light-weight refractory zvidhinha.Iyo insulating light refractory brick ine bauxite seyakanyanya AL2O3 yemukati isingasviki 48%.Maitiro ekugadzira anotora nzira yefuro, uye nzira yekupisa-kunze yekuwedzera inogona kushandiswa zvakare.High-alumina heat-insulating lightweight refractory zvidhinha zvinogona kushandiswa kuvaka-heat-insulatory layers uye nzvimbo dzisina kusimba kwepamusoro-tembiricha yakanyungudutswa kukukurwa kwezvinhu uye kukorobha.Kana yakanangana nemurazvo, tembiricha yekusangana kwepamusoro-yepamusoro-alumina inodzivirira kupisa-inodzivirira zvidhinha haifanire kunge yakakwira kupfuura 1350 ℃.Mullite heat-insulating refractory zvidhinha inogona kubata zvakananga murazvo uye iine hunhu hwepamusoro-tembiricha kuramba, kusimba kwepamusoro, uye inoshamisa-yekuchengetedza simba.Inokodzera jira re pyrolysis furnace, hot blast furnace, ceramic roller kiln, electric porcelain drawer kiln, uye zvakasiyana-siyana zvekupikisa.(6) Clay heat-insulating lightweight refractory zvidhinha zvidhinha zvinopisa zvinopisa zvine AL2O3 zvine 30% kusvika 48% zvakagadzirwa nevhu refractory sechinhu chikuru mbishi.Maitiro ayo ekugadzira anotora iyo yekupisa-kunze plus hunhu nzira uye foam nzira.Kushandisa ivhu refractory, mabheji anoyangarara, uye refractory ivhu clinker seyakagadzirwa, kuwedzera binder uye sawdust, kuburikidza nebhachi, kusanganisa, kuumba, kuomesa, uye kupfura, chigadzirwa chine huwandu hwakawanda hwe 0.3 kusvika 1.5g/cm3 inowanikwa.Kubuda kwevhu kupisa-kuvharidzira zvidhinha kunodarika hafu yehuwandu hwehuwandu hwekupisa-kupisa zvidhinha zvinopisa.
Inonyanya kushandiswa mumavira anoputika, mavhiri anopisa anopisa, mavira ekudziya, masimbi esimbi, coke oveni, carbon furnaces, ladle, ladle casting masisitimu, boilers, simende kilns, magirazi kilns, tunnel kilns, rotary kilns, uye shaft kilns uye mamwe mavhiri ekupisa Simende. uye midziyo inopisa inoshandiswa zvakanyanya musimbi, indasitiri yemakemikari, ceramics, coking, kabhoni, kukanda, michina, magetsi emagetsi, zvekuvaka, peturu, uye mamwe maindasitiri.
