Isicelo
I-silicone carbide ceramicssebenza izindima ezibalulekile ekusebenzeni kweziko ezimbonini emikhakheni eminingi. Isicelo esiyinhloko amabhomu e-silicon carbide burner, asetshenziswa kakhulu ezinhlelweni ezivuthayo ezisezingeni eliphezulu zokucubungula i-metallurgical, ukukhiqizwa kwezingilazi, nokudubula kwe-ceramic ngenxa yokusimama kwesakhiwo ezindaweni ezishisayo kakhulu. Okunye ukusetshenziswa okubalulekile amaroli e-silicon carbide, asebenza njengokusekela nokudlulisa izingxenye kumahhani aqhubekayo, ikakhulukazi ekufakweni kwezitsha zobumba ezithuthukisiwe, izakhi ze-elekthronikhi, kanye nengilazi enembile. Ukwengeza, ama-ceramics e-SiC asetshenziswa njengezakhi zesakhiwo njengemishayo, ama-rails, nama-setters ezithandweni zomlilo, lapho abekezelela ukuchayeka isikhathi eside emkhathini onolaka kanye nengcindezi yemishini. Ukuhlanganiswa kwazo kumayunithi okushintshanisa ukushisa kwezinhlelo zokuthola ukushisa kwemfucuza kuphinde kugqamise ukuguquguquka kwazo ekulawuleni okushisayo okuhlobene neziko. Lezi zinhlelo zokusebenza zigcizelela ukuguquguquka kwe-silicon carbide ezidingweni ezihlukene zokusebenza ngaphakathi kobuchwepheshe bokushisa bezimboni.
Izinhlelo zokusebenza eziyinhloko ze-industrial kiln zihlanganisa:
1.Imibhobho ye-silicon carbide burner
4.Ishubhu elikhazimulayo le-silicon carbide
Izinzuzo Zobuchwepheshe
1. I-Thermal Stability Eyingqayizivele
- Iphuzu elincibilikayo: 2,730°C (ligcina izinga lokushisa eliphakeme kakhulu)
- Ukumelana ne-oxidation kufika ku-1,600 ° C emoyeni (kuvimbela ukuwohloka kwe-oxidative atmospheres)
2. Superior Thermal Conductivity
- 150 W/(m·K) i-thermal conductivity ekamelweni lokushisa (inika amandla ukudluliswa kokushisa okusheshayo nokusabalalisa okufanayo kwezinga lokushisa)
- Yehlisa ukusetshenziswa kwamandla ngo-20–30% uma kuqhathaniswa nezinto ezivamile zokuphikisa.
3. Ukumelana Nokushaqeka Kwe-Thermal Okungenakuqhathaniswa
Imelana nokushintshashintsha kwezinga lokushisa okudlula u-500°C/sec (ilungele izinqubo zokushisisa/zokupholisa ngemijikelezo).
- Igcina ubuqotho besakhiwo ngaphansi kokuhamba ngebhayisikili okushisayo (ivimbela ukuqhekeka nokuguqulwa).
4. Amandla Emishini Ephezulu Emazingeni Okushisa Aphakeme
- Igcina u-90% wamandla ezinga lokushisa legumbi ku-1,400°C (okubalulekile kuzingxenye zomlilo ezithwalayo).
- Ukuqina kwe-Mohs okungu-9.5 (kumelana nokugqokwa kwezinto eziqhumayo endaweni yokushisa umlilo).
| Impahla | I-Silicon Carbide (SiC) | I-Alumina (Al₂O₃) | I-Refractory Metals (isb., ama-alloys ase-Ni) | I-Traditional Refractories (isb, isitini somlilo) |
| Ubukhulu. Izinga lokushisa | Kufika ku-1600°C+ | 1500°C | 1200°C (ithambisa ngenhla) | 1400–1600°C (kuyahlukahluka) |

| I-Thermal Shock Resistance | Kuhle kakhulu | Kumpofu kuya kokumaphakathi | Okulingene (ductility kusiza) | Impofu (iqhekeka ngaphansi kwe-ΔT esheshayo) |
| Amandla Emishini | Igcina amandla emazingeni okushisa aphezulu | Yehlisa izinga ngaphezu kuka-1200°C | Iyancipha emazingeni okushisa aphezulu | Phansi (brittle, porous) |
| Ukumelana Nokugqwala | Imelana nama-asidi, ama-alkali, izinsimbi/i-slag encibilikisiwe | Okulingene (kuhlaselwe ama-asidi/izisekelo eziqinile) | Ithambekele ku-oxidation/sulfidation emazingeni okushisa aphezulu | Yehlisa izinga endaweni edlayo |
| Ubude bempilo | Yinde (ukugqoka/ukumelana ne-oxidation) | Okumaphakathi (imifantu ngaphansi kokuhamba ngebhayisikili okushisayo) | Ifushane (i-oxidize/iyakhasa) | Okufushane (i-spalling, ukuguguleka) |
| Ukusebenza Kwamandla | Phezulu (ukudlulisa ukushisa okusheshayo) | Iphansi (i-thermal conductivity engalungile) | Okulingene (i-conductive kodwa i-oxidize) | Phansi kakhulu (i-insulative) |
Icala Lemboni
Ibhizinisi elihamba phambili lokucubungula i-metallurgical lizuze ukuthuthuka okuphawulekayo kokusebenza ngemva kokuhlanganisa izitsha zobumba ze-silicon carbide (SiC) ezinhlelweni zayo zokushisa ezishisayo. Ngokufaka esikhundleni sezinto ezivamile ze-aluminaamabhomu e-silicon carbide burner, ibhizinisi libike:
✅ Izindleko zokulungisa eziphansi ngo-40% zonyaka ngenxa yokuncipha kokuwohloka kwengxenye endaweni engu-1500°C+.
✅ Ukukhuphuka okungama-20% esikhathini sokukhiqiza, okuqhutshwa i-SiC ukumelana nokushaqeka okushisayo kanye nokugqwala okuvela ku-slag encibilikisiwe.
✅ Ukuqondanisa namazinga okuphathwa kwamandla e-ISO 50001, kusebenzisa i-SiC's high conductivity eshisayo ukuze kuthuthukiswe ukusebenza kahle kukaphethiloli ngo-15-20%.
