Ukuhlukaniswa
Ama-alloy e-electrothermal: ngokuya ngokuqukethwe kwawo kwezakhi zamakhemikhali kanye nesakhiwo, angahlukaniswa ngezigaba ezimbili:
Enye uchungechunge lwe-iron-chromium-aluminium alloy,
Olunye uchungechunge lwe-nickel-chromium alloy, olunezinzuzo zalo njengezinto zokushisa zikagesi, futhi lusetshenziswa kabanzi.
Inhloso eyinhloko
Imishini yensimbi, ukwelashwa, imboni yamakhemikhali, izinto zobumba, izinto zikagesi, izinto zikagesi, ingilazi neminye imishini yokushisa yezimboni kanye nezinto zokushisa zomphakathi.
Izinzuzo kanye nokungalungi
1. Izinzuzo eziyinhloko kanye nokungalungi kochungechunge lwe-iron-chromium-aluminium alloy: Izinzuzo: i-iron-chromium-aluminium eshisayo kagesi i-alloy inokushisa okuphezulu kwesevisi, izinga lokushisa eliphezulu lesevisi lingafinyelela kuma-degrees angu-1400, (0Cr21A16Nb, 0Cr27A17Mo2, njll.), impilo ende yesevisi, umthwalo ophezulu womphezulu, kanye nokumelana okuhle kwe-oxidation, ukumelana okuphezulu, okushibhile njalo njalo. Okubi: Amandla aphansi kakhulu ekushiseni okuphezulu. Njengoba izinga lokushisa landa, ukuqina kwalo kuyanda, futhi izingxenye ziyaguquguquka kalula, futhi akulula ukugoba nokulungisa.
2. Izinzuzo eziyinhloko kanye nokungalungi kochungechunge lwe-alloy yokushisa kagesi ye-nickel-chromium: Izinzuzo: amandla okushisa aphezulu aphezulu kune-iron-chromium-aluminium, akulula ukuwohloka ngaphansi kokusetshenziswa kokushisa okuphezulu, isakhiwo saso akulula ukusishintsha, sithambile kahle, kulula ukusilungisa, sikhipha uketshezi oluningi, asinamandla kazibuthe, simelana nokugqwala. Siqinile, siphila isikhathi eside, njll. Okubi: Ngenxa yokuthi senziwe ngezinto zensimbi ze-nickel ezingavamile, intengo yalolu chungechunge lwemikhiqizo iphakeme kaningana kuneye-Fe-Cr-Al, futhi izinga lokushisa lokusetshenziswa liphansi kunele-Fe-Cr-Al.
okuhle nokubi
Okokuqala, sidinga ukwazi ukuthi intambo yokushisa ifinyelela esimweni esibomvu esishisayo, okuhlobene nokuhleleka kwentambo yokushisa. Ake siqale sisuse umshini wokomisa izinwele bese sisika ingxenye yentambo yokushisa. Nge-transformer engu-8V 1A, ukumelana kwentambo yokushisa noma intambo yokushisa yengubo kagesi akufanele kube ngaphansi kwama-ohm angu-8, ngaphandle kwalokho i-transformer izosha kalula. Nge-transformer engu-12V 0.5A, ukumelana kwentambo yokushisa akufanele kube ngaphansi kwama-ohm angu-24, ngaphandle kwalokho i-transformer izosha kalula. Uma intambo yokushisa ifinyelela esimweni esibomvu esishisayo, uma ibomvu kakhulu kungcono, kufanele usebenzise i-transformer engu-8V 1A, futhi amandla ayo makhulu kune-transformer engu-12V 0.5A. Ngale ndlela, singahlola kangcono izinzuzo kanye nokungalungi kwentambo yokushisa.
1. Izinga lokushisa eliphezulu lokusebenza kwengxenye libhekisela ekushiseni okuphezulu kwengxenye ngokwayo emoyeni owomile, hhayi ekushiseni kwesithando somlilo noma into eshisayo. Ngokuvamile, izinga lokushisa lobuso liphakeme ngama-degrees ayi-100 kunezinga lokushisa lesithando somlilo. Ngakho-ke, uma ucabangela izizathu ezingenhla, ekwakhiweni Naka izinga lokushisa lokusebenza kwezingxenye. Lapho izinga lokushisa lokusebenza lidlula umkhawulo othile, ukushiswa kwezingxenye ngokwazo kuzosheshiswa futhi ukumelana nokushisa kuzoncishiswa. Ikakhulukazi izingxenye ze-alloy yokushisa kagesi yensimbi-chromium-aluminium kulula ukuzishintsha, ukuzibhidliza, noma ukuziphula, okunciphisa isikhathi senkonzo. .
2. Izinga lokushisa eliphezulu lokusebenza kwengxenye linobudlelwano obukhulu nobubanzi bentambo yengxenye. Ngokuvamile, izinga lokushisa eliphezulu lokusebenza kwengxenye kufanele libe nobubanzi bentambo obungaphansi kuka-3mm, kanti ubukhulu bomugqa oyisicaba akufanele bube ngaphansi kuka-2mm.
3. Kukhona ubudlelwano obukhulu phakathi komkhathi oqothulayo esithandweni somlilo kanye nokushisa okuphezulu kokusebenza kwezingxenye, futhi ukuba khona komkhathi oqothulayo kuvame ukuthinta izinga lokushisa lokusebenza kanye nokuphila kwenkonzo kwezingxenye.
4. Ngenxa yamandla aphansi okushisa okuphezulu kwe-iron-chromium-aluminium, izingxenye ziguquguquka kalula emazingeni okushisa aphezulu. Uma ububanzi bentambo bungakhethwanga kahle noma ukufakwa kungafanele, izingxenye zizowa futhi zinciphise i-circuit ngenxa yokuguquguquka kokushisa okuphezulu. Ngakho-ke, kufanele kucatshangelwe lapho kuklanywa izingxenye.
5. Ngenxa yokwakheka kwamakhemikhali ahlukene e-iron-chromium-aluminium, i-nickel, i-chromium kanye nezinye izinhlobo zokushisa zikagesi eziwuchungechunge, izinga lokushisa lokusetshenziswa kanye nokumelana ne-oxidation kunqunywa umehluko wokumelana, okunqunywa ku-iron-chromium heat alloy material Al element of resistivity, i-Ni-Cr electric heating alloy material inquma ukumelana kwe-element Ni. Ngaphansi kwezimo zokushisa okuphezulu, ifilimu ye-oxide eyakhiwe ebusweni be-alloy inquma impilo yesevisi. Ngenxa yokusetshenziswa kwesikhathi eside, isakhiwo sangaphakathi se-element sishintsha njalo, futhi ifilimu ye-oxide eyakhiwe ebusweni nayo iyaguga futhi iyabhujiswa. Izinto ezingaphakathi kwezingxenye zayo zihlala zisetshenziswa. Njenge-Ni, Al, njll., ngaleyo ndlela zifinyeza impilo yesevisi. Ngakho-ke, lapho ukhetha ububanzi bentambo ye-electric furnace, kufanele ukhethe intambo ejwayelekile noma ibhande eliyisicaba elijiyile.
