Izitena eziqhelekileyo ezixhathisayo:Ukuba ucinga ngexabiso kuphela, unokukhetha izitena ezinqabileyo ezinqabileyo, ezifana nezitena zodongwe.Esi sitena siphantsi.Isitena sixabisa kuphela i-$0.5~0.7/block.Inoluhlu olubanzi losetyenziso.Nangona kunjalo, ngaba ifanelekile ukusetyenziswa?Ngokumalunga neemfuno, ukuba ayifezekiswanga, inokubangela ukugcinwa rhoqo ngenxa yokugqoka kunye nokukrazula, kwaye ayinakukwazi ukusetyenziswa ngokuqhelekileyo.Ukugcinwa okuphindaphindiweyo kunokukhokelela ekulungisweni kwangaphambili kunye nomonakalo kwisixhobo, esingafanelanga inzuzo.
Izitena zodongwe zizinto ezibuthathaka ezinobunzima, ezinobunzima bomzimba malunga ne-2.15g / cm3 kunye nomxholo we-alumina we-≤45%.Nangona i-refractoriness iphezulu njenge-1670-1750C, isetyenziswa kakhulu kwiqondo lokushisa eliphezulu le-1400C.Le mveliso inokusetyenziswa kuphela ngokuhambelana neemfuno.Ubushushu, ezinye iindawo ezingabalulekanga, ubushushu obuqhelekileyo bokuqina kwezitena zodongwe aziphezulu, kuphela i-15-30MPa, ezi zihambelana nezalathi zemveliso, nto leyo ekwasisizathu sokuba izitena zodongwe zingabizi kakhulu.
Izitena eziphezulu ze-alumina refractory:Izitena eziphezulu ze-alumina zinamabakala amane asekelwe kwi-alumina.Ngenxa yokuba umxholo we-aluminium wezinto eziluhlaza uphezulu kunezitena zodongwe, igama lezitena eziphezulu ze-alumina zivela kule nto.Ngokwebakala, le mveliso ingasetyenziswa kuluhlu lobushushu obuphezulu lwe-1420 ukuya kwi-1550 ° C.Xa isetyenzisiwe, inokuthi ibonakale kumadangatye.Amandla oxinzelelo oluqhelekileyo lobushushu buphezulu ukuya kuma-50-80MPa.Xa ubonakaliswe kwilangatye, ubushushu bomhlaba abukwazi ukuba phezulu kunobushushu bokusebenza.Oku kuchaphazeleka kakhulu kukuxinana kwemveliso kunye nomxholo we-alumina.
Izitena zeMullite:Izitena eziphikisayo ze-Mullite zine-refractoriness ephezulu kunye nobushushu obuphezulu bokusebenza.Zifumaneka kwiintlobo ezinzima kunye nezilula.Izitena ezinzima ze-mullite ziquka izitena ze-mullite ezidityanisiweyo kunye nezitena ze-mullite ezidibeneyo.Imveliso yokumelana nokothuka kweThermal kulungile;Iimveliso ezikhaphukhaphu zinefuthe elihle lokufakwa kwe-thermal.Iimveliso ezikhaphukhaphu zezi: JM23, JM25, JM26, JM27, JM28, JM30, JM32.Iimveliso ze-mullite ezikhaphukhaphu ziyakwazi ukuvezwa ngamadangatye, kwaye iipores zisasazwa ngokulinganayo Ngokutsho kobunzima obuthile kunye nomxholo wempahla ekrwada yemveliso, i-JM23 ingasetyenziswa ngaphantsi kwe-1260 degrees, i-JM26 engaphantsi kwe-1350 degrees, kunye ne-JM30 ingasetyenziselwa uluhlu lobushushu eliphezulu 1650 degrees.Esi sisizathu sokuba kutheni izitena ze-mullite zibiza.
Izitena zaseCorundum:Isitena se-Corundum sisitena somgangatho ophezulu we-refractory kunye nomxholo we-alumina ongaphezu kwe-90%.Le mveliso ikwaneemveliso ezixutyiweyo nezixutyiweyo.Ngokwezinto ezibonakalayo, iimveliso zibandakanya: isitena se-zirconium corundum (i-AZS, isitena esixutyiweyo), isitena se-chromium corundum, njl. ye-1,700 degrees.Ixabiso lesi sitena esiphikisayo siyahluka ukusuka kumawaka aliqela ukuya kumashumi amawaka eyuan ngetoni nganye ngenxa yezinto ezifana nenkqubo yokuvelisa kunye nomxholo wezinto ezikrwada.
Izitena zebhola ze-alumina:Izitena ze-alumina ezihollow ibhola zizitena zokugquma ezikhaphukhaphu ezixabisa malunga ne-RMB 10,000 ngetoni nganye.Ngenxa yeendawo ezahlukeneyo zokusetyenziswa kunye neenkqubo zokuvelisa, kubandakanywa umxholo we-alumina, njl., ixabiso lemveliso kufuneka libe phezulu., njengoko kuthethwa, ixabiso lemali.
Oku ngasentla kukungeniswa kobuninzi, ukumelana nokushisa okuphezulu kunye nexabiso lezitena eziphikisayo.Ngokuqhelekileyo, ubuninzi bomthamo wezinto eziphikisayo zilinganiswa ngaphambi kokushiya umzi-mveliso.Ubuninzi bomthamo: kubonisa umlinganiselo wobunzima bemveliso eyomileyo kumthamo wayo opheleleyo, ochazwe kwi-g / cm3.
