Dhayamita nehukobvu hwewaya yekudziisa chinhu chinoenderana nekupisa kwakanyanya. Dhayamita yewaya yekudziisa yakakura, zviri nyore kukunda dambudziko rekushanduka kwechinhu pakupisa kwakanyanya uye kuwedzera hupenyu hwayo hwekushanda. Kana waya yekudziisa ichishanda pasi pekupisa kwakanyanya, dhayamita haifanire kunge iri pasi pe3mm, uye ukobvu hwebhandi rakatsetseka hahufanire kunge huri pasi pe2mm. Hupenyu hwebasa hwewaya yekudziisa hunoenderanawo zvakanyanya nedhayamita nehukobvu hwewaya yekudziisa. Kana waya yekudziisa ikashandiswa munzvimbo inodziya zvakanyanya, firimu rekuchengetedza oxide rinogadzirwa pamusoro, uye firimu re oxide rinokwegura mushure menguva yakati, richigadzira kutenderera kwekugadzirwa nekuparadza kunoramba kuripo. Maitiro aya zvakare maitiro ekushandisa zvinhu zviri mukati mewaya yekudziisa yemagetsi. Waya yekudziisa yemagetsi ine dhayamita nehukobvu hwakakura ine zvinhu zvakawanda uye hupenyu hwebasa hwakareba.
1. Zvakanakira zvikuru nezvakaipa zvemhando yesimbi-chromium-aluminium alloy: Zvakanakira: iron-chromium-aluminium electric heating alloy ine tembiricha yepamusoro yebasa, tembiricha yepamusoro yebasa inogona kusvika 1400 degrees, (0Cr21A16Nb, 0Cr27A17Mo2, nezvimwewo), hupenyu hurefu hwebasa, mutoro wepamusoro, uye kuramba kwakanaka kweoxidation, resistivity yakanyanya, yakachipa nezvimwewo. Zvakashata: Simba rakaderera zvakanyanya patembiricha yepamusoro. Sezvo tembiricha ichiwedzera, plasticity yayo inowedzera, uye zvikamu zvinoshanduka nyore nyore, uye hazvisi nyore kukotama nekugadzirisa.
2. Zvakanakira zvikuru nezvakaipa zve nickel-chromium electric heating alloy series: Zvakanakira: simba rekupisa rakakwirira rakakwirira kupfuura re iron-chromium-aluminium, harisi nyore kuchinja kana richishandiswa pakupisa kwakanyanya, chimiro charo hachisi nyore kuchichinja, plasticity yakanaka, iri nyore kugadzirisa, ine emissivity yakawanda, haina magineti, inodzivirira ngura. Yakasimba, inogara kwenguva refu, nezvimwewo. Zvakashata: Nekuda kwekushandiswa kwezvinhu zvisingawanzoitiki zvesimbi ye nickel, mutengo wezvigadzirwa izvi wakakwira kanoverengeka kupfuura weFe-Cr-Al, uye tembiricha yekushandisa yakaderera pane yeFe-Cr-Al
Michina yesimbi, kurapwa, indasitiri yemakemikari, zvedongo, zvemagetsi, zvemagetsi, zvegirazi nezvimwe zvekushandisa pakudziisa maindasitiri pamwe nemidziyo yekudziisa yehurumende.
