Gusaba
Silicon Carbide CeramicsKorera uruhare rukomeye mu bikorwa bya Kiln mu nganda mu mirenge myinshi. Gusaba mbere ni silicon carbide ya Nozzles Nozzles, yakoreshejwe cyane muri sisitemu yo gutwika amabuye y'agaciro kuri metallurgical itunganya, kurangiza ikirahure, kurasa ceramic bitewe nubukungu bwabo bukabije. Ubundi buryo bwo gukoresha ni karbide ya silicon, ikora nk'inkunga kandi itanga ibice bikomeje kuba intambara ikomeza, cyane cyane mu kurema ceramicge yateye imbere, ibice bya elegitoroniki, n'ibihuha. Byongeye kandi, ceramics ya sic ikoreshwa nkibigize imiterere nkibiti, gari ya moshi, kandi ishyiraho itanura rya kiln, aho bihanganira kwibasirwa igihe kirekire hamwe nubushake bwamashanyarazi. Kwishyira hamwe kwabo mubice byubushyuhe kubice byubushyuhe bwa sisitemu yo kugarura ubushyuhe birerekana ibisobanuro byabo mumiyoborere ya Kiln. Izi porogaramu zishimangira guhuza na silicon Carbide kubisabwa bitandukanye mubikorwa byo gushyushya inganda.
Ibyingenzi bya Kiln zirimo:
1.Silicon carbide yatwitse nozzles
4.Silicon carbide urumuri tube
Ibyiza bya Tekinike
1. Umutekano udasanzwe
- Gushonga Ingingo: 2,730 ° C (Ikomeza Ultra-Ibidukikije Byinshi Byuzuye)
- Kurwanya okiside kugeza 1.600 ° C mu kirere (birinda gutesha agaciro mu kirere cya okiside)
2. Ikirangantego cyo mu bushyuhe
- 150 w / (min) gukora ubushyuhe mu bushyuhe bwicyumba (butuma kwimura ubushyuhe bwihuse hamwe no gukwirakwiza ubushyuhe bumwe)
- Kugabanya ibicuruzwa bya 20-30% ugereranije nibikoresho gakondo.
3. Kudacogora
- Kurwanya Flicture Ubushyuhe bwihuse buhebuje 500 ° C / SEC (Nibyiza gushyushya gukonja / gukonjesha).
- Kubungabunga ubunyangamugayo bwo gusiganwa ku magare (birinda gucapa no kubyamamaza).
4. Imbaraga nyinshi zakanishi ku bushyuhe bwo hejuru
- Gumana 90% byimbaraga-zubushyuhe kuri 1.400 ° C (Ibyingenzi kubigize imitwaro ya Kiln).
- MOHS Ikomeye ya 9.5 (irwanya kwambara ibikoresho bya Aburamu muri Kiln ibidukikije).
| Umutungo | Silicon carbide (sic) | Alumina (Al₂o₃) | Ibyuma byo kugarura (urugero, ni-ishingiye kuri alloys) | Gukosora gakondo (urugero, firebrick) |
| Max. Ubushyuhe | Kugeza kuri 1600 ° C + | 1500 ° C. | 1200 ° C (Softens hejuru) | 1400-1600 ° C (biratandukanye) |
| Ubushyuhe | Hejuru (120-200 W / M · k) | Hasi (~ 30 w / m · k) | Guciriritse (~ 15-50 w / M · k) | Hasi cyane (<2 w / m · k) |
| Kurwanya Ubushyuhe | Byiza | Abakene kuringaniye | Guciriritse (umuyoboro bifasha) | Abakene (ibice munsi ya vuba Δt) |
| Imbaraga za mashini | Kugumana imbaraga mubushyuhe bwo hejuru | Degrade hejuru ya 1200 ° C. | Gucika intege ku bushyuhe bwo hejuru | Hasi (kuvunika, kubaga) |
| Kurwanya Kwangirika | Irwanya acide, alkalis, ibyuma byashongeshejwe / slag | Gishyira mu gaciro (kwibasiwe na acide ikomeye / Base) | Ukunda kuri okiside / sulfidation kuri temps ndende | Gutesha agaciro ikirere cyangiza |
| Ubuzima | Kirekire (kwambara / okiside-irwanya) | Gushyira mu gaciro (ibice munsi y'amagare yo gusiganwa ku magare) | Ngufi (okiside / kunyerera) | Ngufi (guhunga, isuri) |
| Ingufu | Hejuru (kwimura cyane cyane) | Hasi (imyitwarire mibi yubushyuhe) | Mu buryo buciriritse (kuyobora ariko oki)) | Hasi cyane (kwikuramo) |
Urubanza
Ikigo gishinzwe gutunganya metallurgical itunganya ibikorwa bikomeye nyuma yo guhuza karomu ya silicon (sic) muburakari bwa Sitemics. Mugusimbuza ibice byinshi bihuye nasilicon carbide yatwitse nozzlesUrushinga rwatunguye:
✅ 40% yo hasi buri mwaka ibiciro bitewe no kugabanya guterwa ibice 1500 ° C + ibidukikije.
Kwiyongera 20% mu musaruro uhira, bitwarwa na Sic Kurwanya Ubushyuhe na Rarosion kuva ishonga.
Guhuza hamwe nisomero yo gucunga ingufu, imikoreshereze ya sic yo hejuru yubushyuhe bworoshye gukora neza kuri 15-20%.
