Indima eyinhloko yezitini zokufakelwa ukugcina ukushisa nokunciphisa ukulahlekelwa ukushisa. Izitini zokuvikela ukushisa ngokuvamile azixhumani ngqo nelangabi, futhi izitini zomlilo ngokuvamile zithintana nelangabi. Izitini zomlilo zisetshenziswa kakhulu ukumelana nelangabi lokuthosiwe. Ivamise ukuhlukaniswa ngezinhlobo ezimbili, okuyizinto eziphikisayo ezingapheli ezingabunjiwe kanye nezinto eziphikisayo ezinomumo.
I-Refractory Material Engabunjiwe
I-castables refractory material iyizinhlayiyana eziyimpuphu ezixubene ezakhiwe ngamaqoqo ahlukahlukene noma ama-aggregate kanye nesibophezelo esisodwa noma ngaphezulu. Ukusetshenziswa kufanele kuxutshwe noketshezi olulodwa noma ngaphezulu, olunoketshezi olunamandla.
I-Shaped Refractory Material
Ezimweni ezijwayelekile, ukwakheka kwezitini eziphikisayo kunosayizi ojwayelekile, kungabuye kwenziwe ngokwezifiso ngokuya ngezidingo zamakhasimende.
Umehluko Oyinhloko Phakathi Kwezitini Zokushisisa Nezitini Zomlilo
1. Ukusebenza kwe-Insulation
I-thermal conductivity yezitini zokufakelwa ngokuvamile i-0.2-0.4 (isilinganiso sokushisa 350±25°C)w/mk, futhi ukuqhutshwa kokushisa kwe-firebrick kungaphezu kwe-1.0 (isilinganiso sokushisa 350±25°C)w/mk Ngakho-ke, ukufakwa okushisayo ukusebenza kwezitini zokufakelwa kungcono kakhulu kunezitini zomlilo.
2. Ukungavumelani
I-refractoriness yesitini sokushisa ngokuvamile ingaphansi kwama-degree angu-1400, futhi ukuphikiswa kwesitini esiphikisayo kungaphezu kwama-degree angu-1400.
3. Ukuminyana
Izitini ezibamba ukushisa ziyizinto zokufaka izinto ezingasindi, ukuminyana kwezitini zokufakelwa ngokuvamile zingu-0.8-1.0g/cm3 futhi ukuminyana kwezitini eziphikisayo ngokuyisisekelo kungaphezu kuka-2.0g/cm3.
Isiphetho
Kafushane, isitini esiphikisayo sinamandla amakhulu emishini, impilo ende yesevisi, ukuzinza okuhle kwamakhemikhali, akukho ukusabela kwamakhemikhali ngezinto kanye nokumelana okuhle kwezinga lokushisa eliphezulu, futhi izinga lokushisa eliphakeme elimelana nokushisa lingafinyelela ku-1900 ° C. Izitini ze-Refractory zifaneleka ngokukhethekile ukusetshenziswa kuma-high-low-low shift converters, ama-reformers, ama-converter e-hydrogenation, amathangi e-desulfurization, kanye neziko le-methanation lezitshalo zomanyolo wamakhemikhali ukuze zibambe iqhaza ekuhlakazeni uketshezi lwegesi, ukusekela, ukumboza nokuvikela ama-catalysts. Izitini ze-refractory zomlilo nazo zingasetshenziswa ezitofini ezishisayo kanye nemishini yokuguqula ukushisa embonini yensimbi.
Izitini zomlilo zinezinzuzo zokuminyana okuphezulu, amandla aphezulu, ukumelana nokugqoka, ukumelana nokugqwala okuhle, i-coefficient ephansi yokwandisa ukushisa okushisayo, ukusebenza kahle kokugaya okuphezulu, umsindo ophansi, impilo ende yesevisi, nezinto ezingangcolisi. Kuyindlela enhle yokugaya efanele imishini ehlukahlukene yokugaya.
Izitini eziphikisayo nezitini zokufakelwa zihluke kakhulu, ukusetshenziswa kwazo kwemvelo, ububanzi kanye nendima akufani. Izinto ezihlukene zizosetshenziswa ezindaweni ezahlukene. Lapho sithenga izinto zokwakha, kufanele sinqume ukuthi yiluphi uhlobo lwezinto eziphikisayo ezifanele ukusetshenziswa kwethu ngokwesimo sethu sangempela.
