Izitofu ezisebenzisa ama-recarburizer zifaka phakathi izitofu zikagesi, ama-cupola, izitofu zikagesi ze-arc, izitofu zokungenisa imvamisa ephakathi, njll., ukuze inani lensimbi elahliwe likhuliswe kakhulu, futhi inani lensimbi yengulube lingancishiswa noma kungasetshenziswa nsimbi yengulube.
I-recarburizer ngempela iwusizo olukhulu ekukhiqizweni kwama-castings. Kuzo zonke izinsimbi ezibunjiwe (insimbi empunga, insimbi ethambile, insimbi ye-vermicular graphite, insimbi empunga, insimbi emhlophe, njll.), i-graphite ku-recarburizer ye-graphite ingasetshenziswa njenge-Nuclei ye-pro-eutectic ye-graphite kanye ne-eutectic graphite. Ama-castings ahlukene adinga izinhlobo ezahlukene zama-recarburizer. Ngokombono wezindleko, ukukhetha i-recarburizer efanelekile kusiza kakhulu ikhwalithi yama-castings kanye nezinzuzo zomnotho. Ngaphezu kwalokho, izifundo zikhombisile ukuthi ngezilinganiso ezahlukene zama-recarburizer e-carbonaceous kanye nenqubo ye-carburizing, ngaphansi kwesimo sokwakheka kwamakhemikhali okufanayo kokugcina kwensimbi encibilikisiwe, okuqukethwe kwe-nitrogen ku-cast iron e-carburised kuyanda, kanti i-nitrogen eyakhiwe yi-nitrogen iyanda. I-Boronide, njll., ingasetshenziswa njengesisekelo se-graphite crystalline core, idala izimo ezinhle ze-nucleation kanye nokukhula kwe-graphite. Ngaleyo ndlela kuthuthukisa ikhwalithi yama-castings.
Ngaphansi kwezimo ezijwayelekile, i-recarburizer ifakwa esithandweni kanye nensimbi eqoshiwe kanye nezinye izindleko. Ukwengezwa kwemithamo emincane kungafakwa ebusweni bensimbi encibilikisiwe, noma kungangezwa ngobuningi ngamaqoqo. (Qaphela: Gwema ukuphakela insimbi encibilikisiwe ngobuningi obukhulu ukuze uvimbele ukungcoliswa ngokweqile, okuholela emphumeleni ongabalulekile we-carburizing kanye nomonakalo omkhulu ekubunjweni.)
Uma usebenzisa ama-recarburizer ekubunjweni, kufanele kuqashelwe ukuthi inani le-recarburizer elingeziwe likhethwa ngokuya ngobukhulu bezitofu ezahlukene kanye nokushisa kwesitofu. Ngezinhlobo ezahlukene zensimbi ephonswe, izinhlobo ezahlukene zama-recarburizer kufanele zikhethwe ngokuya ngezidingo. Okuqukethwe kwe-recarburizer emakethe kusatshalaliswa kakhulu kusuka ku-75-98.5. Ngezidingo zemakethe zekhwalithi yomkhiqizo, imakethe ye-recarburizer nayo iyashintshashintsha, ikakhulukazi ukukhethwa kwama-recarburizer afakwe i-graphitized kuthathe isinyathelo esibalulekile. Ngakho-ke, ukukhethwa kwama-recarburizer okubunjiwe nakho kuyindlela enhle kakhulu yokwazi.
