Furnace tekinoroji ye fused alumina corundum neutral ramming zvinhu zve induction vira

Maitiro akasiyana siyana echishandiswa chevhenekeri maitiro akakoshawo zvakanyanya kuhupenyu hwebasa remoto, uye akasiyana maitiro asina kufanira anogona kudzora hupenyu hwebasa hwevira. Naizvozvo, anotevera mapoinzi anofanirwa kutariswa panguva yekushandiswa.

(1) Sezvo sintered layer ye ramming material yechoto chitsva iri nhete, mashandisirwo echoto chitsva akakosha zvikuru. Choto chekutanga chevira idzva chinofanira kuwedzera 50% yemvura inofanira kunyungudutswa. Izvi zvinogona kudzivisa kukanganisa kwakadai sekuputika uye kuputika kunokonzerwa nekukurumidza kutonhora kwechigadziko chevira mushure mokunge mvura yose yabudiswa; choto chitsva chinofanira kuramba chichinyungudutswa zvakanyanya sezvinobvira kudzivirira kunyunguduka kwepakati. Mitswe inobuda inofanira kunyungudutswa nguva dzose kwevhiki imwe.

(2) Edza kudzivirira kunyungudika kwekushisa kwakanyanya panguva yekunyungudika. Pakupisa kwakanyanya, jira rechoto rinoita nesimbi yakanyungudutswa mucrucible, sezvinoratidzwa mune inotevera formula: SiO2+2C→Si+2CO. Iyo yakakwira tembiricha, iyo yakakwirira yeC uye yakaderera iyo Si, kuparara kwechoto chevira kuchawedzera, kunyanya muIzvo zvinonyanya kuoneka kana choto chiri chitsva, saka edza kudzivirira kupisa kwepamusoro paunenge uchivimbisa tembiricha yemvura kana ichinyunguduka.

(3) Dzivisa kupisa kwebindu rechoto. Nekuti mwero wekupisa weyepakati frequency furenace unokurumidza, kana munyungudusa usinga terere, kuchaja kuchaita se “bhiriji” uye vhezheni yechoto ichaita seyakagadzirwe tembiricha yepamusoro kana kutopfuura iyo refractoriness yevira rechoto, izvo zvinogona kukonzera. jira rechoto kuti rinyunguduke uye riparadze kukuvara.

(4) Panguva yekushandiswa, kana choto ichida kuvharwa kwenguva yakareba nekuda kwekutadza uye zvimwe zvikonzero, simbi yakanyungudutswa muchoto inofanira kudururwa kudzivirira tambo yechoto kuti isaparare nekuda kwekutsemuka kwembambo yechoto. kana simbi yakaumbwa yanyungudutswa.

(5) Edza kushandisa chaji yakachena panguva yekushandisa, kunyanya kana choto chiri chitsva.

6 Panguva imwecheteyo, kudzivirira kuputika kunokonzerwa nekusiyana kwekushisa kwakanyanya pakati pepamusoro nepamusoro tembiricha yevheni yevira panguva yekutonhora, chifukidziro chechoto chinofanira kuvharwa kuti chigadzirise vhezheni yevira Panguva yekutonhora, mativi ekumusoro uye epasi akaenzana. , kuitira kuti ave nechokwadi chehupenyu hwebasa rechoto.

(7) Sezvo mitswe yakatwasuka ichioneka kana choto ichitonhora, apo choto chinotonhora chinotangwa, choto chacho chinofanira kubikwa patembiricha yakaderera isati yanyunguduka, kuitira kuti mitswe yacho itange yavharwa, uye mitswe yacho inogona kudziviswa kuti isapinda. mumitswe apo simbi yakanyungudutswa inonyunguduka uye mitswe inowedzerwa.

(8) Teerera kumamiriro echoto panguva yekushandiswa kwechoto. Kucherechedza mamiriro echoto rudzi rwekudzivirira kwechoto. Pasi pechoto chinoyerwa mazuva ose e3, uye rusvingo rwevira runofanira kucherechedzwa pachoto chimwe nechimwe zuva rega rega, nokudaro kuve nechokwadi chekuchengetedzwa kwechigadziko chevira. .

(9) Kuchengetedza uye kugadzirisa kwemidziyo yemoto induction, senge kucheneswa kwecoil, kuchenesa marara pacoil kudzivirira kuparara kwekoiri, nekudaro kudzivirira kuparara kwechoto kunokonzerwa nekutadza kwemidziyo, uye nekuvandudza hupenyu hwebasa recrucible.
