Izihlungi ze-Ceramic Foam (CFF) ziyizingxenye zokuhlunga ezisezingeni eliphezulu ezibaluleke kakhulu embonini yesimanje ye-foundry kanye neye-metallurgical. Zinesakhiwo esiyingqayizivele samaseli avulekile axhumene nge-3D, zisusa ngempumelelo izinto ezifakiwe kanye nokungcola ensimbini encibilikisiwe, ziqinise ukugeleza koketshezi, futhi zithuthukise kakhulu ikhwalithi yokukhipha kanye nomkhiqizo. Ngokuqina okuhle kokushisa, ukumelana nokugqwala kwamakhemikhali kanye namandla aqinile omshini, izihlungi ze-ceramic foam ziye zaba yisisombululo sokuhlanza esithandwayo sokukhipha insimbi ngokunemba emhlabeni wonke.
Sihlinzeka ngezihlungi ze-foam ze-ceramic ezijwayelekile nezenziwe ngokwezifiso ukuze zivumelane nezimo ezahlukahlukene zokubumba zezimboni. Kunezinhlobo ezintathu zezinto ezisetshenziswa kakhulu: i-alumina, i-silicon carbide kanye ne-zirconia. Izihlungi ze-alumina zilungele ukubumba i-aluminium alloy esezingeni eliphansi. Izihlungi ze-silicon carbide zimelana namazinga okushisa afinyelela ku-1560°C, zilungele ama-alloy ethusi kanye nokucutshungulwa kwensimbi esezingeni eliphakathi. Izihlungi ze-zirconia zinikeza ukumelana kokuguguleka okuphezulu, eziklanyelwe ngokukhethekile ukubumba insimbi ehlanzekile kakhulu kanye nensimbi engagqwali. Izihlungi zethu zimboza ububanzi obuphelele bosayizi we-pore kusukela ku-10 PPI kuya ku-60 PPI. Amamodeli e-10-20 PPI anikeza amazinga aphezulu okugeleza kwama-ingot amakhulu, ama-PPI angu-20-30 alinganisa ukunemba nokusebenza kahle kokukhiqizwa kwe-billet ejwayelekile, kanye nezihlungi ze-30-60 PPI ezi-ultra-fine zisusa ukungcola okuncane kokubumba okucacile odongeni oluncane. Yonke imikhiqizo igcina ama-porosity aphezulu angu-75%-85% ukuqinisekisa ukugeleza kwensimbi okubushelelezi kanye nokusebenza okuzinzile kokuhlunga.
Njengoba zenzelwe izindawo zokusebenza ezinzima, ama-CFF ethu anokumelana okukhulu kokushaqeka kokushisa kanye nokumelana okunamandla nokukhuhla insimbi encibilikisiwe. Awabangeli ukungcola kwesibili futhi agcina ubuqotho besakhiwo obuzinzile ngaphansi kokusebenza okuqhubekayo kokushisa okuphezulu. Iyahambisana nokuthungwa kwesihlabathi, ukuthungwa kwesikhunta okuhlala njalo kanye nokuthungwa kokutshalwa kwezimali, lawa mahlungi angafakwa kalula ezitsheni zokuthela, ezigijimayo kanye nasezitsheni zokuhluza ukuze kuhlanzwe insimbi ngendlela ephumelelayo.
Zisetshenziswa kabanzi ekukhiqizweni kwensimbi yensimbi nengeyona eyensimbi, izihlungi zethu zihlanza i-aluminium encibilikisiwe yezingxenye zezimoto, izingxenye zezindiza kanye namaphrofayili ezakhiwo. Zisusa ama-oxide ethusi nasethusini ukuze zithuthukise ukuhanjiswa kukagesi, kuyilapho amamodeli e-silicon carbide enamandla aphezulu kanye ne-zirconia ehlunga insimbi encibilikisiwe ukuze kube nezingxenye zemishini eziqinile nezinembile.
Izihlungi ze-ceramic foam zekhwalithi ephezulu zinciphisa ngempumelelo ukukhubazeka kokubumba okufana nokugoba kanye nokufakwa kwe-slag, amazinga aphansi okulahla kanye nokunciphisa izindleko zokukhiqiza. Kwenziwe ngaphansi komthetho oqinileIzindinganiso ze-ISO, izihlungi zethu zinikeza ukusebenza okuzinzile nokuthembekile ekukhiqizweni ngobuningi, kusiza izinkampani zokusekela ukuthuthukisa izinqubo nokuthuthukisa izinzuzo zezomnotho.
Sinikeza izixazululo zobuchwepheshe ezenziwe ngokwezifiso ngokusekelwe ezintweni zakho zokusakaza, izimo zokusebenza kanye nemininingwane yomkhiqizo. Usekelo lokwenza ngokwezifiso okungejwayelekile kanye nama-oda amaningi anesitoko esanele kanye nokulethwa okuzinzile.
