Daim ntawv thov
Silicon carbide ceramicsua lub luag haujlwm tseem ceeb hauv kev lag luam kiln ua haujlwm thoob plaws ntau qhov chaw. Ib daim ntawv thov tseem ceeb yog silicon carbide burner nozzles, dav siv nyob rau hauv high-temperature combustion systems rau metallurgical ua, iav manufacturing, thiab ceramic firing vim lawv structural stability nyob rau hauv huab cua kub ib puag ncig. Lwm qhov kev siv tseem ceeb yog silicon carbide rollers, uas ua raws li kev txhawb nqa thiab kev xa khoom hauv cov kilns tas mus li, tshwj xeeb tshaj yog nyob rau hauv sintering ntawm advanced ceramics, electronics Cheebtsam, thiab precision iav. Tsis tas li ntawd, SiC ceramics tau ua haujlwm raws li cov khoom siv xws li kab teeb, rails, thiab setters nyob rau hauv lub cub tawg, qhov chaw uas lawv tiv taus ntev raug rau huab cua hnyav thiab kev ntxhov siab. Lawv kev koom ua ke rau hauv cov khoom siv hluav taws xob sib txawv rau cov khoom siv hluav taws xob pov tseg ntxiv qhia txog lawv cov kev ua tau zoo hauv kev tswj xyuas qhov cub hluav taws xob. Cov ntawv thov no underscore silicon carbide lub adaptability rau ntau yam kev xav tau ntawm kev lag luam cua sov technologies.
Cov ntawv thov tseem ceeb ntawm cov kiln muaj xws li:
1.Silicon carbide burner nozzles
4.Silicon carbide radiant tube
Technical Advantage
1. Exceptional Thermal Stability
- Melting point: 2,730 ° C (txheej txheem ultra-high-temperature ib puag ncig)
- Oxidation tsis kam mus txog 1,600 ° C hauv huab cua (tiv thaiv kev degradation hauv oxidative atmospheres)
2. Superior Thermal Conductivity
- 150 W / (m·K) thermal conductivity nyob rau hauv chav tsev kub (ua kom kub hloov pauv sai thiab sib faib kub)
- Txo kev siv hluav taws xob los ntawm 20-30% piv rau cov khoom siv refractory tsoos.
3. Tsis sib xws Thermal Shock Resistance
- Nrog kev hloov pauv sai ntawm qhov kub siab tshaj 500 ° C / sec (zoo tagnrho rau cov txheej txheem cua sov / cua txias).
- Ua kom muaj kev ncaj ncees nyob rau hauv thermal cycling (tiv thaiv kev tawg thiab deformation).
4. Lub zog siv tshuab siab ntawm qhov kub siab
- Khaws 90% ntawm chav tsev kub ntawm lub zog ntawm 1,400 ° C (tseem ceeb rau cov khoom siv thauj khoom hnyav).
- Mohs hardness ntawm 9.5 (tiv thaiv hnav los ntawm cov ntaub ntawv abrasive nyob rau hauv kiln ib puag ncig).

| Max. Kub | Txog li 1600 ° C + | 1500 ° C | 1200 ° C (softens saum toj no) | 1400-1600 ° C (ntaus) |
| Thermal conductivity | Siab (120-200 W / m·K) | Tsawg (~ 30 W / m·K) | Nruab nrab (~ 15-50 W / m·K) | Tsawg heev (<2 W/m·K) |
| Thermal Shock Resistance | Zoo heev | Poob rau nruab nrab | Nruab nrab (ductility pab) | Tsis zoo (kawg hauv qab nrawm ΔT) |
| Mechanical Strength | Khaws lub zog ntawm qhov kub thiab txias | Degrades saum 1200 ° C | Tsis muaj zog ntawm qhov kub thiab txias | Tsawg (nkig, ntxeem tau) |
| Corrosion Resistance | Resistant acids, alkalis, molten hlau / slag | Nruab nrab (sib ntaus los ntawm cov kua qaub / cov hauv paus) | Yooj yim rau oxidation / sulfidation ntawm lub siab kub | Degrades nyob rau hauv corrosive cua |
| Lub neej ntev | Ntev (hnav / oxidation-resistant) | Nruab nrab (kawg nyob rau hauv thermal cycling) | Luv (oxidizes / creeps) | Short (spalling, yaig) |
| Zog Efficiency | High (hloov pauv kub ceev) | Tsawg (tsis zoo thermal conductivity) | Nruab nrab (conductive tab sis oxidizes) | Tsawg heev (insulative) |
