Dab tsi yog cov khoom ntawm cov lub thawv-hom ua haujlwm rauv

box-type resistance furnace yog tsim los ntawm lub cub tawg thav duab, lub plhaub ntawm lub cub tawg, lub tshuab hluav taws xob, lub tshuab hluav taws xob, lub tshuab hluav taws xob qhov rooj, hluav taws xob cua sov thiab cov cuab yeej pabcuam.

Next, let’s understand the role of each part of the box-type resistance furnace

1. Rauv thav duab: Lub luag haujlwm ntawm lub tshuab ua kom sov yog los ua lub luag haujlwm ntawm lub qhov cub hauv ob sab phlu thiab cov khoom ua haujlwm. Nws yog feem ntau welded rau hauv ib tug ncej nrog seem steel thiab coated nrog steel phaj. Lub thawv me me rau qhov cub tsis tas yuav tsum tau nruab nrog lub tshuab ua kom sov, thiab lub plhaub ntawm lub cub tawg yog welded los ntawm cov hlau tuab, uas tuaj yeem ua lub luag haujlwm ntawm lub cub tawg. Rau qee qhov, nws kuj ua lub luag haujlwm tiv thaiv.

2. Lub plhaub ntawm lub cub tawg: Lub luag haujlwm ntawm lub plhaub ntawm lub tshuab hluav taws xob yog los tiv thaiv lub tshuab hluav taws xob hauv ob sab phlu, ntxiv dag zog rau cov qauv ntawm lub cub tawg hluav taws xob thiab tswj lub airtightness ntawm lub cub hluav taws xob. Nws yog feem ntau welded nrog steel daim hlau overlaid ntawm steel ncej. Qhov tsim nyog tsim ntawm lub cub tawg thav duab thiab lub plhaub ntawm lub cub tawg muaj lub zog txaus.

3. Rauv hauv ob sab phlu: Qhov ua haujlwm ntawm lub tshuab ua kom sov yog los tiv thaiv qhov kub ntawm lub thawv-hom tiv thaiv rauv thiab txo cov cua sov. Cov khoom siv hauv ob sab phlu zoo yuav tsum tsis yog tsuas yog muaj qee qhov ntawm cov refractoriness, tiv thaiv kom txias thiab kub ceev, tab sis kuj muaj tsawg dua cov cua sov. Lub qhov cub hauv ob sab phlu yog tsim los ntawm cov ntaub ntawv refractory thiab cov ntaub ntawv khaws cia thaum tshav kub kub, cov khoom siv refractory yog nyob ze rau lub tshuab hluav taws xob cua sov, thiab cov khoom txuag hluav taws xob yog ze rau lub plhaub sab nraud. Yuav kom txo tau cov cua sov, cov hauv ob sab phlu ntawm lub qhov cub hluav taws xob tau txais kev tsim hluav taws xob peb txheej, thiab cov txheej sab hauv siv cov ntaub ntawv refractory, xws li polycrystalline mullite fiberboard thiab zirconium-muaj fiberboard; nruab nrab thiab txheej txheej siv cov ntaub ntawv rwb thaiv tsev, siab aluminium lossis txheem Ceramic fiber board, muaj kev xav, fiber ntau daim pam, thiab lwm yam. Lub hauv ob sab phlu ntawm nruab nrab-kub lub thawv rauv yog ua los ntawm lub teeb refractory thiab thermal rwb thaiv tsev cov ntaub ntawv xws li siab alumina los yog aluminium silicate refractory. fiber ntau, thiab fiber ntau daim pam cov ntaub ntawv feem ntau yog siv nyob rau hauv txheej nyob ze ntawm lub cub tawg plhaub. Vim tias qhov kub thiab txias ntawm lub qhov cub hluav taws xob qis, cov khoom siv ntawm cov txheej txheem refractory thiab cov txheej txheem rwb thaiv tsev tsis siab, thiab cov khoom siv txhuas silicate refractory fiber ntau tuaj yeem ua tau raws li qhov yuav tsum tau ua. Ua li no, lub tshuab hluav taws xob hluav taws xob tuaj yeem tiv thaiv tau zoo dua.

4. Lub qhov rooj rauv: Lub qhov rooj ntawm lub qhov cub rauv feem ntau yog ua los ntawm cam khwb cia hlau lossis steel phaj. Ib qho kev txwv kev txwv kev nyab xeeb yog ntsia rau ntawm lub qhov cub qhov rooj qhib lub cuab yeej thiab cuam tshuam nrog cov cua sov tswj fais fab mov. Thaum lub qhov rooj rauv qhib, lub hwj chim tswj tau raug txiav tawm los tiv thaiv kev ua haujlwm. Kev nyab xeeb ntawm tus neeg. Txhawm rau ua kom yooj yim rau kev soj ntsuam cov cua kub hauv lub qhov cub, qhov kev soj ntsuam feem ntau yog tsim nyob rau hauv nruab nrab ntawm lub qhov cub qhov rooj. Qhov no ua rau muaj kev saib xyuas zoo ntawm kev ua haujlwm ntawm lub thawv rauv.

5. Heating elements: The heating elements of box-type resistance furnaces often use resistance wires, silicon carbide rods, silicon molybdenum rods, etc. Their main function is to heat up.

6. Cov cuab yeej pabcuam: Cov cuab yeej pabcuam ntawm lub thawv rauv yog cov thermocouple, uas yog siv rau kev ntsuas kub. Ntxig lub thermocouple ncaj qha mus rau hauv lub cub tawg kom saib xyuas qhov kub ntawm qhov sib txawv hauv qhov cub tawg.

Cov saum toj no yog cov kev taw qhia ntawm lub thawv-type resistance furnace chaw tsim tshuaj paus ntawm lub ntsiab Cheebtsam ntawm lub thawv-hom rauv thiab lub luag hauj lwm ntawm txhua feem. Yog tias tsim nyog, thov nrog peb tham.
