Nta
Peb liRiser leegrau kev lag luam me meyog engineered los txhim kho casting efficiency, thiab wordercision hlau txaus, ua rau muaj ib qho kev sib xyaw ua ke nyob rau hauv cov ntawv thov ua ke zoo li kev siv tsheb thiab aerospace. Nrog cov khoom siv khoom tshaj lij, suav nrogSilicon Carbide (Sic), Silicon Nitride (Si₃n₄), thiabNitride-Bonded Silicon Carbide (NBSC), peb muab cov kev daws teeb meem uas muaj rau qhov tshwj xeeb ntawm txhua lub chaw ua haujlwm.
Cov Khoom Siv Khoom thiab Xaiv Cov Khoom Siv
Cov leeg riser yog qhov tseem ceeb nyob rau hauv qis-siab casting thauj mus los molten hlau los ntawm lub cub tawg mus rau mould rau mould mus rau mould mus rau mould mus rau mould rau cov tswj tau. Cov leeg cov khoom siv 'cov khoom siv yog qhov tseem ceeb los ua kom muaj qhov kub thiab txias, thiab kev sib cuam tshuam ntsuas dej. Peb cov ntaub ntawv tseem ceeb tau sau tseg hauv qab no, nrog cov ncauj lus kom ntxaws ntawm txhua cov khoom siv tshwj xeeb thiab cov kev lag luam zoo.
Cov khoom sib piv
| Khoom | Cov Nta Tseem Ceeb | Qhov Zoo | Tsis zoo |
|---|---|---|---|
| Silicon Carbide (Sic) | Siab siab thermal conductivity, oxidation tsis kam | Raug nqi-ua tau zoo, ruaj, thiab thermally ruaj khov | Moderate tsis kam rau huab cua sov heev |
| Silicon Nitride (Si₃n₄) | Kev kub siab rau siab ntev, thermal poob siab tiv | Superior deturable, tsawg hlau nplaum | Tus nqi siab dua |
| Nitride-Bonded Silicon Carbide (NBSC) | Ua ke ntawm Si₃n₄ thiab Sic Procerties | Pheej yig, haum rau cov uas tsis-ferrous | Kev muaj mob ntev dua piv rau cov ntshiab si₃n₄ |
Silicon Carbide (Sic)Yog siv dav rau General-hom phiaj casting vim nws sib npaug ntawm cov nqi-ua hauj lwm zoo thiab thermal conductivity.Silicon Nitride (Si₃n₄)yog qhov zoo rau high-end Casting xav tau, muab kev zam tshwj xeeb thermal tsis kam thiab muaj peev xwm loj hauv qhov chaw siab.Nitride-Bonded Silicon Carbide (NBSC)Ua hauj lwm ua kev xaiv kev lag luam rau cov ntawv thov uas ob qho khoom muaj txiaj ntsig thiab cov khoom sic tau zoo dua.
Cov Nta Tseem Ceeb
- Siab siab thermal conductivity: Nrawm thiab txawm tias kub hloov pauv, zoo tagnrho rau kev tswj cov hlau tswj cov hlau ntawm qhov ntsuas kub.
- Thermal poob siab tsis kam: Tsim los tuav cov kev hloov pauv kub heev, uas txo qhov kev pheej hmoo ntawm kev tawg.
- Kev corrosion thiab oxidation tsis kam: Enhanced durability txawm nyob rau hauv txoj kev siv tshuaj lom ib puag ncig.
- Tus Hlau Hlau Ntws: Ua kom cov khoom xa tuaj ntawm Molten hlau, txo kev kub ntxhov thiab ua kom muaj kev kub siab zoo.
Qhov zoo ntawm peb cov leeg riser
- Txhim Kho Casting EquiciCiymievic: Los ntawm kev txhawb nqa du thiab tswj kav hlau txaus, peb cov leeg riser pab txo cov khoom tsis xws luag thiab txhim kho cov khoom lag luam xaus.
- Ntev-kav ntev: High hnav tsis kam thiab thermal endurance txo qhov zaus ntawm kev hloov pauv.
- Zog siv tau: Advanced Thermal cov khoom ua kom cov hlau bolten tseem nyob ntawm qhov ntsuas kub, pab txhawb kom muaj kev noj haus qis dua.
Kev Ua Tshwj Xeeb

Cov Ntawv Thov Siv
Cov leeg riser tau siv nyob rau hauvTsawg-siab tuag castingNyob thoob plaws kev lag luam xws li:
- Automotive: Cov khoom siv rau cov cav ntoo, cov log, thiab cov qauv txheej txheem.
- Ib tug tub rog: Precision cov khoom sib tw yuav tsum muaj lub zog siab thiab kub ua kom tau.
- Khoom siv hluav taws xob: Cheebtsam nrog cov geometries ntau thiab siab thermal conductivity.
Cov Lus Nug
- Q: Cov khoom twg yog qhov zoo tshaj rau txhuas casting?
A:Silicon nitride (Si₃n₄) yog qhov kev xaiv saum toj vim nws lub durability thiab qis wettability nrog txhuas, txo thiab oxidation. - Q: Kuv tuaj yeem tau txais cov lus sau sai sai npaum li cas?
A:Peb muab cov lus hais hauv 24 teev raws li tau txais cov ntaub ntawv ntxaws xws li qhov ntev, kom muaj nuj nqis, thiab daim ntawv thov. - Q: Dab tsi yog cov hmoov txhuas rau kev txiav txim ntau?
A:Feem ntau, lub sijhawm coj yog 7-12 hnub, nyob ntawm qhov ntau thiab cov lus qhia tshwj xeeb.
