Yam ntxwv ntawmsilicon carbide rauv tubes

Silicon carbide rauv tubeyog silicon carbide ua cov khoom siv tseem ceeb, zoo heevcov khoom siv silicon carbideua los ntawm kub kub firing, nrog kub kub kuj, ceev thermal conductivity, siab zog, siab hardness, zoo hnav tsis kam, zoo tshav kub tsis kam thiab av qeeg kuj, zoo thermal conductivity, zoo oxidation kuj thiab lwm yam zoo heev zog ntawm ob qho tag nrho cov installation. tshwj xeeb kub rwb thaiv tsev npog. Nws tuaj yeem tiv thaiv corrosion ntawm cov hlau tov ntawm hluav taws xob cua sov cov ntsiab lus (xws li silicon rods, hluav taws xob cua sov rauv hlau, thiab lwm yam), thiab daim ntawv thov tseem ceeb ntawm silicon carbide tiv thaiv hlab nrog ntau yam ntsuas zoo dua li cov khoom ntawm ntau yam graphite muaj thermal conductivity, oxidation tsis kam, kub poob tsis kam, thiab kub tsis kam

Manufacturing technology ntawm silicon carbide rauv tube

Cov khoom lag luam yog silicon carbide ua cov khoom siv tseem ceeb, los ntawm cov txheej txheem tshwj xeeb ntawm kev kub siab roasting ntawm cov khoom zoo silicon carbide, cov qauv ntev tuaj yeem kho raws li qhov xav tau tiag tiag ntawm cov neeg siv khoom.

Thawj siv ntawmsilicon carbide rauv tubes

Siv dav hauv kev cob qhia tsis-ferrous hlau, aluminium khoom degassing system, luam ntawv thiab dyeing machinery, zinc thiab txhuas kev cob qhia thiab cov khoom lag luam thiab lwm yam haujlwm.

Kev tsim kho ntawm silicon carbide rauv tube

Silicon carbide furnace tube muaj cov yam ntxwv ntawm lub siab input impedance, tsis tshua muaj suab nrov, zoo linearity, thiab lwm yam. Nws yog ib qho ntawm cov khoom siv ceev ceev ntawm silicon carbide tam sim no, thiab nws tau ua lag luam ua ntej. Piv nrog MOSFET Cheebtsam, JFET Cheebtsam tsis muaj teeb meem kev ntseeg tau tshwm sim los ntawm lub rooj vag oxygen txheej tsis xws luag thiab kev txwv ntawm cov cab kuj tsis tshua muaj zog, thiab tswj kom muaj peev xwm ua haujlwm tau zoo vim muaj kev ua haujlwm tsis zoo. Tsis tas li ntawd, JFET cov cuab yeej muaj kev ua haujlwm zoo thiab kev ntseeg siab ntawm qhov kub thiab txias. Vim yog cov qauv ntawm lub rooj vag electrode ntawm silicon carbide JFET ntaus ntawv, qhov pib voltage ntawm JFET feem ntau yog qhov tsis zoo, uas yog, muaj ntau yam khoom siv, uas yog qhov tsis zoo rau nws daim ntawv thov hauv kev siv hluav taws xob hluav taws xob, thiab yog incompatible nrog tam sim no universal tsav Circuit Court. Los ntawm kev qhia txog cov cuab yeej siv cuab yeej ntawm kev txhaj tshuaj zawj lossis mesa zawj qauv, cov cuab yeej txhim kho nrog lub xeev ua haujlwm tau tsim. Txawm li cas los xij, txij li cov khoom siv tau zoo tshaj plaws feem ntau yog tsim tus nqi ntawm cov yam ntxwv tas li, nws yog qhov yooj yim ntawm cov khoom siv tas li (depetion hom) jfet, thiab txoj kev sib txuas cov depletion hom JFET cov cuab yeej siv rau cov hlua txuas sab sauv yog ua tiav los ntawm kev sib txuas cov hluav taws xob qis Si chav MOSFETs hauv koob. Lub tshuab hluav taws xob ntawm lub cuab yeej JFET cascaded yog ib txwm sib xws nrog cov khoom siv hluav taws xob ntawm lub hom phiaj silicon. Cov qauv cascade yog qhov tsim nyog rau cov khoom siv hluav taws xob siab thiab cov khoom siv hluav taws xob siab, ntau dua li cov khoom siv silicon IGBT, ncaj qha kom tsis txhob muaj teeb meem kev sib raug zoo ntawm lub voj voog tsav.

Qhov zoo ntawm silicon carbide yog raws li nram no.

1, lub tshav kub hloov pauv muaj nuj nqi zoo, lub raj phab ntsa yog nyias (tsuas yog ob peb millimeters), cov khoom kub hloov teb yog sov heev;

2, tsis cuam tshuam los ntawm corrosion

3, kub tsis yaj, hlau ua kua tsis muaj kuab paug;

4, tuaj yeem siv los yaj sodium thiab strontium nplua nuj alloy;

5, cov tsos ntawm cov khoom tsis txuas nrog lub slag, kev tiv thaiv yog yooj yim heev;

6, kub tsis kam 1600;

7. Muaj zog thermal shock tsis kam

8, siab hardness, tsis yooj yim rau tawg

9 Nqi-zoo, lub neej nyob rau hauv ntau tshaj li ib nrab xyoo.

Cov saum toj no yog cov yam ntxwv ntawm kev ua haujlwm ntawm silicon carbide rauv tube, yog tias koj xav paub ntau ntxiv, koj tuaj yeem tiv tauj peb!
