Izitini eziphikisayoyizici ezibalulekile zanoma yisiphi isicelo sezimboni, futhi ukukhethwa kwesitini esifanele kunoma yisiphi isicelo kuyisinqumo esibalulekile. Isitini esiphikisayo esilungile singathuthukisa ukusebenza kwesicelo, sandise isikhathi saso sokuphila futhi sinciphise ukusetshenziswa kwamandla. Ukukhetha isitini esifanele isicelo esifanele kubalulekile ukuze uqinisekise impumelelo yokufaka. Kulesi sihloko, sizoxoxa ngezinto ezihlukahlukene okufanele zicatshangelwe lapho kukhethwa isitini esifanele se-refractory sezinhlelo zokusebenza ezihlukene zezimboni.
1. Izinga lokushisa: Izinga lokushisa lohlelo lokusebenza kufanele libe yisici sokuqala okufanele sicatshangelwe lapho kukhethwa izitini eziphikisayo. Izicelo ezihlukene zinezidingo ezihlukene zokushisa, futhi isitini esifanele esiphikisayo kufanele sikwazi ukumelana nokushisa kwesicelo. Ukushisa kwesicelo kufanele kucatshangelwe lapho kukhethwa isitini esiphikisayo, njengoba ezinye izitini zenzelwe ukusebenza ngaphansi kwamazinga okushisa athile, kanti ezinye zenzelwe amazinga okushisa aphezulu.
2. Ukumelana:Izitini eziphikisayokufanele futhi kukhethwe ngokusekelwe ukumelana kwabo nezakhi ezahlukene. Isibonelo, ezinye izitini ziklanyelwe ukumelana kangcono nama-alkali nama-asidi, kuyilapho ezinye zenzelwe ukumelana kakhulu nokugqwala nokuhuzuka. Kubalulekile ukucabangela imvelo yesicelo lapho ukhetha isitini esiphikisayo, njengoba singathinta ukusebenza kwezitini.
3. I-Porosity: I-Porosity iyisici esibalulekile okufanele icatshangelwe lapho ukhetha isitini esiphikisayo, njengoba singathinta izakhiwo ezishisayo zesitini. I-porosity yisilinganiso semali yomoya ongadlula esitini, futhi kubalulekile ukucabangela lokhu lapho ukhetha isitini sohlelo lokusebenza oluthile. Isitini esine-porosity ephakeme sizoba nokumelana nokushisa okungcono kanye ne-thermal conductivity, kuyilapho isitini esine-porosity ephansi sizomelana kakhulu nokushisa okushisayo.
4. Ukwakheka kwamakhemikhali: Ukwakheka kwamakhemikhali esitini esiphikisayo nakho kuyisici esibalulekile okufanele sicatshangelwe lapho kukhethwa isitini esifanele sohlelo lokusebenza. Ukuqanjwa kwamakhemikhali ahlukene kuzonikeza amazinga ahlukene okumelana nezakhi ezahlukene. Kubalulekile ukuqonda ukwakheka kwamakhemikhali kwesicelo ukuze ukhethe isitini esifanele somsebenzi.
5. Izindleko: Izindleko zingenye into okufanele icatshangelwe lapho ukhetha isitini esiphikisayo. Izitini ezihlukene zinezindleko ezihlukene, futhi kubalulekile ukucabangela izindleko zesitini ngokuphathelene nezindleko zesicelo. Ukukhetha isitini esibiza kakhulu kungase kudingeke uma sidingeka ukuze kuhlangatshezwane nezidingo zokusebenza zohlelo lokusebenza.
Sengiphetha, lapho ukhetha ilungeloisitini esiphikisayongesicelo, kubalulekile ukucabangela izinga lokushisa, ukumelana, i-porosity, ukwakheka kwamakhemikhali, nezindleko zesitini. Kubalulekile futhi ukuqonda imvelo yesicelo ukuze ukhethe isitini esingcono kakhulu somsebenzi. Ukuthatha isikhathi sokucabangela zonke lezi zici kuzosiza ekuqinisekiseni ukuthi isitini esiphikisayo esifanele sikhethiwe kunoma yisiphi isicelo.
