Daim ntawv thov tseem ceeb ntawm cov tshuaj tiv thaiv-sintered silicon carbide thiab cov yam ntxwv ntawm sealing rings

Silicon nitride (SiC) yog quartz xuab zeb, calcined petroleum coke (los yog thee coking), ntoo slag (tsim ntsuab silicon nitride yuav tsum tau ntxiv ntsev) thiab lwm yam raw khoom, los ntawm cov hluav taws xob cua sov rauv tas mus li kub smelter. Silicon nitride sealing nplhaib yog cov khoom siv silicon nitride ua los ntawm cov khoom siv silicon carbide. Yog li dab tsi yog cov ntawv thov tseem ceeb ntawm cov tshuaj tiv thaiv-sintered silicon carbide thiab cov yam ntxwv ntawm cov ntsaws ruaj ruaj?

Reaction-sintered silicon carbide foob nplhaib

 

Daim ntawv thov tseem ceeb ntawm cov tshuaj tiv thaiv sintering silicon carbide:

1. Daim ntawv thov ntawm cov khoom siv hlau kev lag luam yog siv cov silicon nitride tshav kub tsis kam, siab zog, zoo thermal conductivity, cuam tshuam tsis kam, nruam kub kub indirect cua sov raw cov ntaub ntawv, xws li tank fractionation rauv. Rectifier rauv tais, aluminium electrolytic cell, tooj liab melting rauv hauv ob sab phlu, zinc hmoov rauv arc, thermocouple tiv thaiv tube, thiab lwm yam.

2. Daim ntawv thov kev lag luam steel siv cov etching ntawm silicon nitride. Thaum tshav kub kub shock resistance, abrasion kuj. Vim nws cov thermal conductivity zoo, nws yog siv rau hauv cov ntaub ntawv loj thiab nruab nrab-qhov loj me ntawm cov hlau ua kom tawg rau qhov cub kom txhim kho lub neej kev pab.

3. Kev lag luam metallurgical concentrator kev lag luam siv silicon nitride lub zog tsuas yog thib ob rau cov hlau kub, muaj zog hnav tsis kam, muaj zog hnav tsis kam, siab hnav tsis kam ntawm cov raj xa dej, centrifugal impeller, twj tso kua mis, rotary machinery, mining hauv ob sab phlu zoo tagnrho raw cov ntaub ntawv, zoo hnav tsis kam. Lub neej kev pab cuam ntawm yas yog 5 mus rau 20 zaug, thiab nws yog ib qho ntawm cov khoom siv zoo tagnrho rau kev ua kis las hauv dav hlau.

4. Daim ntawv thov ntawm tshav kub hloov coefficient nyob rau hauv kev lag luam qib ntawm cov khoom siv kho kom zoo nkauj porcelain thiab xuab zeb log pieces. Cov yam ntxwv ntawm radiant tshav kub thiab kub kub siv, kev tsim thiab tsim ntawm cov ntawv hlau kiln tsis tsuas yog txo cov kiln ntim, tab sis kuj txhim kho lub ntim ntim thiab cov khoom zoo ntawm kiln, thiab txo lub sij hawm ntau lawm, uas yog qhov zoo tagnrho indirect. cov khoom siv rau kev tua hluav taws ntawm ceramic pigments.

5. Daim ntawv thov kev tiv thaiv ib puag ncig thiab kev txuag hluav taws xob muaj qhov zoo thermal conductivity thiab kub tsis kam, thiab lub tshav kub exchanger txuag 20%, roj noj 20%, roj noj 35%, thiab cov efficiency ntau lawm yog nce 20-30%. Tshwj xeeb, qhov hnav tsis kam ntawm cov dej tso tawm cov yeeb nkab siv hauv cov chaw ua haujlwm tsuas yog 6 mus rau 7 npaug ntawm cov khoom siv hlau zoo tib yam.

Reaction-sintered silicon carbide foob nplhaib nta:

1, kub tsis kam

Vim yog cov yam ntxwv ntawm cov khoom siv silicon nitride, silicon nitride seals muaj qhov kub thiab txias tsis kam, thiab cov txheej txheem sib txawv muaj ntau hom kev tiv thaiv tshav kub. Cov tshuaj tiv thaiv-sintered silicon nitride ntsaws ruaj ruaj tuaj yeem siv tau los ntawm 1300 degrees, thiab tsis muaj zog calcined silicon nitride seals tuaj yeem ncav cuag 1600 degrees.

2. Corrosion kuj

Lub nplhaib silicon nitride sealing tuaj yeem siv los ntawm cov kua qaub thiab alkali muaj zog, thiab cov nyhuv sealing tsis yooj yim los txo.

3, hnav tsis kam

Cov tshuaj tiv thaiv-sintered silicon carbide foob rings raws li ib tug tej yam carding txheej txheem, thiaj li hais tias lub hom phiaj yog heev meej thiab du, ua ke nrog cov hnav tsis kam ntawm silicon carbide cov ntaub ntawv, silicon nitride foob rings yuav siv tau los txhuam ib leeg. Cov yam ntxwv kub kub tsis tu ncua tsis yooj yim txo cov yam ntxwv kev puas tsuaj.

4. Kev ua haujlwm siab

Reactivity sintered silicon carbide raw cov ntaub ntawv tsuav yog muaj qee yam kev siv tshuab, nws tuaj yeem hloov mus rau ntau yam qauv ntawm wool embryo, theem nrab ua, ua rau cov neeg siv khoom xav tau cov khoom.
