Indima ephambili yezitena zokugquma kukugcina ubushushu kunye nokunciphisa ukulahleka kobushushu. Izitena ze-insulation ngokuqhelekileyo azidibanisi ngokuthe ngqo nomlilo, kwaye i-firebrick idla ngokudibana ngokuthe ngqo nomlilo. Izitena zomlilo zisetyenziswa ikakhulu ukumelana namadangatye osiwe. Ngokuqhelekileyo yohlulwe ibe ziindidi ezimbini, ezizezi, i-indefinite Unshaped refractory imathiriyeli kunye nemathiriyeli emile erefractory.
Izinto eziRefractory ezingamiliselwanga
I-castables refractory imathiriyeli yi-particle exutywe ngumgubo eyenziwe ngeentlobo ezahlukeneyo okanye i-aggregates kunye ne-binder enye okanye ngaphezulu. Usetyenziso kufuneka luxutywe nolwelo olunye okanye ngaphezulu, kunye nolwelo olunamandla.
IMilo yokuRefractory Material
Kwiimeko eziqhelekileyo, imilo yezitena eziphikisayo zinobungakanani obuqhelekileyo, zinokuthi zenziwe ngokwezifiso ngokweemfuno zabathengi.
Umahluko oPhambili phakathi kwezitena zokuKhusela kunye nezitena zomlilo
1. Ukusebenza kweInsulation
I-conductivity ye-thermal yezitena zokugquma ngokuqhelekileyo yi-0.2-0.4 (iqondo lokushisa eliphakathi kwama-350±25 ° C) w/mk, kunye ne-thermal conductivity ye-firebrick ingaphezulu kwe-1.0 (iqondo lokushisa eliphakathi kwe-350±25 °C)w/mk Ngoko ke, ukugqunywa kwe-thermal. ukusebenza kwezitena zokugquma zingcono kakhulu kunezitena zomlilo.
2. Ukuchasa
I-refractoriness yesitena esikhuselayo ngokuqhelekileyo ingaphantsi kwe-1400 degrees, kwaye i-refractoriness yesitena esichasayo ingaphezulu kwe-1400 degrees.
3. Ukuxinana
Izitena ze-insulation zizinto zokugquma ezikhaphukhaphu, ubuninzi bezitena ze-insulation ngokuqhelekileyo ziyi-0.8-1.0g / cm3 kwaye ubuninzi bezitena eziphikisayo zingaphezulu kwe-2.0g / cm3.
Ukuqukumbela
Isishwankathelo, isitena esichasayo sinamandla amakhulu omatshini, ubomi benkonzo ende, ukuzinza kakuhle kweekhemikhali, akukho mpendulo yeekhemikhali kunye nezinto eziphathekayo kunye nokumelana nokushisa okuphezulu, kwaye ubushushu obuphezulu bokushisa bunokufikelela kwi-1900 ° C. Izitena eziRefractory zilungele ukusetyenziswa kwi-high-low-low shift converters, abaguquleli, abaguquleli be-hydrogenation, iitanki ze-desulfurization, kunye neziko le-methanation yezityalo zesichumisi sekhemikhali ukudlala indima yokusasaza ulwelo lwegesi, ukuxhasa, ukugquma, kunye nokukhusela ii-catalysts. Izitena zokucima umlilo zingasetyenziselwa kwizitofu ezishushu kunye nezixhobo zokuguqula ukufudumala kwishishini lensimbi.
Izitena zomlilo zineenzuzo zokuxinana okuphezulu, amandla aphezulu, ukuxhathisa ukunxiba, ukuxhathisa okulungileyo kwe-corrosion, i-coefficient ephantsi yokwandisa i-thermal, ukusebenza kakuhle kokusila, ingxolo ephantsi, ubomi benkonzo ende, kunye nezinto ezingangcolisi. Yindlela yokugaya efanelekileyo efanelekileyo kumashishini ahlukeneyo okugaya.
Izitena eziphikisayo kunye nezitena zokufakelwa zihluke kakhulu, ukusetyenziswa kwazo kwendalo, ububanzi kunye nendima azifani. Izinto ezahlukeneyo ziya kusetyenziswa kwiindawo ezahlukeneyo. Xa kuthengwa izinto eziphathekayo, kufuneka sithathe isigqibo sokuba yeyiphi na into efanelekileyo yokusetyenziswa kwethu ngokwemeko yethu yokwenyani.
