Application
Silicon carbide ceramicsshanda mabasa akakosha mumabasa ekubikira maindasitiri muzvikamu zvakawanda. Chishandiso chekutanga ndeyesilicon carbide burner nozzles, inoshandiswa zvakanyanya mukupisa-tembiricha yekupisa masisitimu ekugadzira metallurgical, kugadzira magirazi, uye kupfura kweceramic nekuda kwekugadzikana kwavo munzvimbo dzinopisa zvakanyanya. Kumwe kushandiswa kwakakosha ndeyesilicon carbide rollers, iyo inoshanda setsigiro uye kuendesa zvinhu mumoto unoramba uripo, kunyanya mukunyunguduka kwemakaramiki epamberi, zvinhu zvemagetsi, uye girazi chairo. Pamusoro pezvo, SiC ceramics inoshandiswa senge matanda, njanji, uye maseta muvira remoto, kwavanotsungirira kuratidzwa kwenguva refu kune hutsinye mhepo uye kushushikana kwemagetsi. Kubatanidzwa kwavo mumayuniti ekupisa kupisa kwemarara ekudzoreredza masisitimu kunowedzera kujekesa kwavo kuita kwakasiyana-siyana mumoto une chekuita nekupisa. Aya maapplication anosimbisa kuchinjika kwesilicon carbide kune akasiyana mashandiro ekuda mukati meindasitiri yekudziya tekinoroji.
Akakosha maindasitiri kiln application anosanganisira:
1.Silicon carbide burner nozzles
4.Silicon carbide inopenya chubhu
Technical Advantages
1. Inoshamisa Thermal Kugadzikana
- Nzvimbo yekunyungudika: 2,730 ° C (inochengetedza nzvimbo dzepamusoro-pamusoro-tembiricha)
-Oxidation kuramba inosvika 1,600 ° C mumhepo (inodzivirira kushatisa mumhepo inokonzeresa)
2. Superior Thermal Conductivity
- 150 W/(m·K) thermal conductivity patembiricha yekamuri (inogonesa kukurumidza kutamisa kupisa uye kugovera tembiricha yakafanana)
- Inoderedza kushandiswa kwesimba ne20-30% zvichienzaniswa neyechinyakare refractory zvinhu.
3. Unmatched Thermal Shock Resistance
- Inomira nekukurumidza kuchinja kwekushisa kunodarika 500 ° C / sec (yakanakira cyclic kudziyisa / kutonhora maitiro).
- Inochengetedza kutendeseka kwechimiro pasi pekupisa bhasikoro (inodzivirira kuputika uye deformation).
4. High Mechanical Strength at Elevated Temperatures
- Inochengetedza 90% yekamuri-tembiricha simba pa1,400 ° C (yakakosha kune inotakura-inotakura honi zvikamu).
- Mohs kuomarara kwe9.5 (inoramba kupfeka kubva kune abrasive zvinhu munzvimbo dzemoto).
| Property | Silicon Carbide (SiC) | Alumina (Al₂O₃) | Refractory Metals (semuenzaniso, Ni-based alloys) | Traditional Refractories (semuenzaniso, firebrick) |
| Max. Tembiricha | Kusvikira ku1600°C+ | 1500°C | 1200°C (inopfava pamusoro) | 1400–1600°C (zvinosiyana) |
| Thermal Conductivity | Pamusoro (120–200 W/m·K) | Yakaderera (~30 W/m·K) | Pakati nepakati (~15–50 W/m·K) | Yakaderera zvakanyanya (<2 W/m·K) |
| Thermal Shock Resistance | Excellent | Murombo kusvika Pakati | Pakati nepakati (ductility inobatsira) | Varombo (kutsemuka pasi pekukurumidza ΔT) |
| Mechanical Simba | Inochengetedza simba pakupisa kwakanyanya | Inodzikira kupfuura 1200°C | Inopera simba pakupisa kukuru | Yakaderera (brittle, porous) |
| Corrosion Resistance | Inopikisa asidhi, alkalis, simbi dzakanyungudutswa / slag | Pakati (inorwiswa neakasimba acids / mabhesi) | Inotarirwa kune oxidation / sulfidation panguva yakakwirira tembiricha | Kunoshatisa mumhepo inoora |
| Hupenyu hurefu | Kureba (kupfeka/kupokana neoxidation) | Zvine mwero (zvimedu pasi pemhepo inopisa) | Pfupi (inowedzera oxidize / inokambaira) | Pfupi (spalling, erosion) |
| Kushanda Kwesimba | Yakakwira (inokurumidza kupisa kupisa) | Yakaderera (yakashata kupisa conductivity) | Zvine mwero (zvinoita asi oxidizes) | Yakaderera zvakanyanya (insulative) |
Indasitiri Nyaya
Iyo inotungamira metallurgical process bhizinesi yakawana yakakosha mashandiro ekuvandudza mushure mekubatanidza silicon carbide (SiC) ceramics mune yayo yepamusoro-tembiricha kiln masisitimu. Nekutsiva zvakajairwa alumina zvikamu nesilicon carbide burner nozzles, bhizinesi rakashuma:
✅ 40% yakaderera mutengo wepagore wekugadzirisa nekuda kwekuderedzwa kwechikamu mu1500 ° C+ nharaunda.
✅ 20% kuwedzera kwekugadzira nguva, inotungamirwa nekupokana kweSiC kune kuvhunduka kwekushisa uye ngura kubva kune yakanyungudutswa slag.
✅ Kurongeka neISO 50001 simba rekutonga zviyero, inosimudzira SiC's yakakwirira yekupisa conductivity kukwirisa kushanda kwemafuta ne15-20%.
