Iko kushandiswa kwakaringana kwemukati lining zvinhu zvechoto chemukati uye nzira yekuvaka choto.

1. Chii chinosumwa pano ndeichi: Quartz acid yakaoma furnace wall lining ramming material (acid furnace wall lining material). Nyaya iyi ndeye pre-yakasanganiswa yakaoma ramming musanganiswa. Izvo zviri mukati binder, anti-cracking agent uye stabilizer zvakagadzirirwa zvinoenderana nezvinodiwa, uye mushandisi anogona kuzviisa zvakananga mukushandisa. Kunyanya kutarisisa: vashandisi havabvumidzwe kuwedzera chero zvinhu uye mvura kana uchishandisa. Ichi chigadzirwa chakakodzera kunyungudutsa grey iron, simbi chena, kabhoni simbi, yakakwira gong simbi, yakakwira chromium simbi, alloy simbi, particle simbi, washing zvinhu, mhangura, aruminiyamu uye zvimwe zvinhu mu induction choto.

2. Kuvaka choto, ovheni uye sintering process

Usati waoma-knotting madziro echoto, tanga waisa jira reasbestosi muchoto coil insulation layer, uye nemaoko nhanho uye compact yega yega yechinhu panguva yekuisa.

Knotted furnace pasi: Ukobvu hwechoto chepasi hunosvika 200mm-280mm, uye jecha rinozadzwa kaviri kana katatu kudzivirira kusaenzana kwese kwese kana bhuku rekugadzira, uye madziro evira revira mushure mekubikira uye kunyungudika hakuna kuomarara. Naizvozvo, kukora kwechikafu kunofanira kunyatsodzorwa. Kazhinji, kukora kwejecha rekuzadza hakupfuuri 100mm / nguva yega yega, uye madziro echoto anodzorwa mukati me60mm. Multi-person oparesheni inokamurwa kuita mashift, 4-6 vanhu pashift, 30 maminetsi zvinotsiva nguva imwe neimwe knotting, kutenderedza choto Chengetedza zvishoma nezvishoma uye shandisa zvakaenzana kuti udzivise kusaenzana density.

Apo mapfundo ari pasi pechoto anosvika paurefu hunodiwa, crucible mold inogona kuiswa nekuikwesha. Panyaya iyi, kutarisirwa kunofanira kutorwa kuti ive nechokwadi chokuti crucible mold inopindirana necoil, inogadziriswa vertically kumusoro uye pasi, uye chimiro chiri pedyo sezvinobvira kusvika pasi pechoto chakavakwa. Mushure mekugadzirisa iyo yekutenderera clearance kuti ienzane, shandisa matatu emapuranga wedges kusungirira, uye yepakati yekusimudza uremu inotsikirirwa kudzivirira madziro echoto kuti asarove. Kutamiswa kwejecha requartz kunoitika panguva yeknotting.

Knotting madziro echoto: Ukobvu hwemukati wemadziro echoto ndeye 90mm-120mm, kuwedzera yakaoma knotting zvinhu mumabhechi, jira rakafanana, ukobvu hwekuzadza hahupfuuri 60mm, uye knotting imaminitsi gumi nemashanu (manual. knotting) kusvika yatsvuka nechekumusoro kwekoiri . Iyo crucible mold haibudiswe kunze mushure mekunge knotting yapera, uye inoita basa rekuita kudziyisa panguva yekuomesa uye kunyura. Kana iwe uchida kubvisa crucible mold, peta madziro ekunze ecrucible mold ne 15-2 layers yepepanhau usati wavhara madziro echoto uye uiputire zvakasimba ne tepi. Mushure mekuputira, rusvingo rwevira rinopisa kusvika ku3 degrees, uye pepanhau rinoputirwa. Bvisa crucible mold nekukurumidza. Iyo dhiramu yesimbi ine dhayamita ye900-10 cm uye kureba kwemuromo wechoto yakati sandara uye pini yesimbi inoshandiswa pakuita kudziyisa panguva yekuomesa uye kunyura.

Kubika uye sintering zvirevo: kuti uwane iyo matatu-layer chimiro chechoto chevira, iyo yekubikira uye sintering process yakakamurwa kuita matanho matatu: teerera kune pini yesimbi uye simbi diki yakawedzerwa muchoto panguva yekubikira nekupisa. Usawedzera zvidimbu zvakakura zvesimbi, inonongedza kana mazino.

Kubika nhanho: Kupisa crucible mold kusvika 900 ° C kwemaminitsi makumi maviri pamwero we20 kupisa kuchengetedza kwemaminitsi makumi maviri, 200 kuchengetedza kupisa kwemaminitsi makumi maviri, uye 20 kuchengetedza kupisa kwemaminitsi makumi maviri. Chinangwa ndechekubvisa zvachose unyoro mumadziro echoto.

Semi-sintering stage: Chengetedza tembiricha iri pa400 kwemaminitsi makumi maviri, 20 kwemaminitsi makumi maviri, uye 500 kwemaminitsi makumi maviri. Kupisa kunofanirwa kudzorwa kudzivirira kutsemuka.

Yakazara sintering nhanho: yakakwira tembiricha sintering, iyo sintered chimiro checrucible ndiyo hwaro hwekuvandudza hupenyu hwayo hwesevhisi. Kupisa kwekupisa kwakasiyana, kuwanda kweiyo sintering layer haina kukwana, uye hupenyu hwebasa hwakaderedzwa zvakanyanya.

Mune 2T induction furnace, anenge 950 kilogiramu emapini esimbi anowedzerwa kuti awedzere kupisa kweiyo coil panguva yekubika. Sezvo kubheka nekunyunguduka kuchienderera mberi, simba remagetsi rakadzikama rinogadzirwa kuburikidza neakaderera-simba kutapurirana kukwenya simbi yakanyungudutswa kuti izadze choto. Kupisa kwechoto kunosimudzwa kusvika ku1700 degrees kuchengetedza kutonhora kwemaminetsi makumi matanhatu, kuitira kuti mukati memadziro echoto inopisa zvakafanana kumusoro uye pasi. Nyatsodzora tembiricha yezvikamu zvitatu zveshanduko yejecha requartz, simudzira iyo yakazara chikamu shanduko yejecha requartz, uye gadzirisa yekutanga sintering simba rembiru yevira revira.

3. pfupiso

Kwehupenyu hwehuni hwemadziro emadziro echoto chekupinza, kunze kwekuvimbisa yakakwana uye inonzwisisika matatu-layer madziro evira, kutarisisa kunofanirwa kubhadharwa kune yakajairika kushanda. Scientific kubika uye sintering maitiro, yakasimba mashandiro ekuita, anogona kuwedzera hupenyu hwechoto.

4. Packaging uye kuchengetedza nzira

Multi-layer hunyoro-proof bepa uye yemukati firimu kurongedza 25kg / bhegi, chengeta munzvimbo yakaoma kudzivirira kunyura hunyoro. Kurudziro yehupenyu hwesherufu yakanyanya kunaka
