Nzira yekugadzira graphite heating rod mu vacuum fire

Chitofu chevacuumtsvimbo yegirafitiinonziwo "vacuum furnace graphite heating rod". Kare kare, vanhu vakashandura graphite kuita kabhoni, saka inonzitsvimbo yekabhoni. Chinhu chakagadzirwa negrafiti carbon rod igrafiti, iyo inonzi adhesive molding. Inogona kugadzirwa kuita zvigadzirwa zvegrafiti zvemaumbirwo akasiyana-siyana, kusanganisira graphite round rod. Nekuda kwehunhu hwegrafiti, ine hunhu hwakanaka hwakasiyana sengekutenderera kwemhepo, mafuta ekuzora, kuramba kupisa kwakanyanyanezvimwewo. Nokudaro, tsvimbo yekabhoni yegirafiti inewokutenderera kwakanaka kwazvo, kupinza kupisa, mafuta ekuzora,kuramba kupisa kwakanyanyanezvimwe zvinhu. Mamiriro ezvinhu eramangwana ndeekuti zvinhu zvegrafiti hazvichinjwe. Saka, kugadzirwa nekuwanikwa kwematanda egrafiti zvakasiyana, uye mashandiro ematanda egrafiti anogadzirwa achasiyana. Saka tingasiyanisa sei? Zvigadzirwa zvegrafiti zvakagadzirwa zvakananga nehupfu hwegrafiti nenamira, kana kutanga zvagadzirwa kuita zvinhu zvakakura zvikweya, izvo zvinogadziriswa nemuchina zvichienderana nemufananidzo kana chimiro chechigadzirwa.
Kune misiyano mikuru uye hunhu pakati petsvimbo yakatenderera yegraphite yakagadzirwa nenzira yekutanga netsvimbo yakatenderera yegraphite yakagadzirwa nenzira yechipiri. Nekuda kwekushomeka kwakakwana panguva yekuburitsa,tsvimbo yegrafiti yakawedzerwaneupfu hwegrafiti ne namatidziro zvichave zvakapfava zvikuru, zvine huremu husina kunaka uye kusimba kwemhepo kwakakura (maburi makuru). Guruva richadonha rava muchimiro chechisikigo, uye richapararira kana rakanyikwa nedoro. Panguva imwe chete, nekuda kwehuwandu hwakawanda hwe namatidziro, conductivity, heat conduction uye lubrication ye graphite rod zvichaderera zvikuru, Chikonzero chiri nyore kwazvo. Grafiti chinhu chinofambisa uye namatidziro izvinhu zvinodzivirira, izvo zvinoderedza zvakanyanya kufambiswa kwesimbi yegrafiti. Zita rakajairika resimbi iyi yegrafiti carbon rod nderekuti carbon arc air gouging carbon rod. Inoshandiswa kucheka mufoundry. Pamusoro pesimbi iyi panofanira kuputirwa nemhangura kudzivirira hunyoro uye kuendesa magetsi. Saka, mhando iyi yesimbi yekabhoni inewo chinhu chekuti dhayamita yacho ichave iri pasi pe 0.1-0.2mm yakanyorwa, nekuti pamusoro payo painongosvika dhayamita yakanyorwa kana yaputirwa nesimbi ye10%.
Kunyangwe nzira yechipiri yakagadzirwawo nehupfu hwegraphite ne namati, pane kusimbiswa kukuru pamaitiro ayo. Chekutanga, hupfu hwegraphite ne namati hunoshandiswa kugadzira hombezvinhu zvegrafitipasi pekumanikidzwa kwakanyanya, uye ipapoyakanyudzwanekupisa kwakanyanya (kuoma uye kuputika kweglue). Nenzira iyi, hapana kana gundi rinonamira mugraphite mushure mekugocha zvakare. Maitiro aya ekugocha impregnation akakosha zvikuru. Kudzikira kwegraphite mushure mekugocha impregnation kune hunhu hwegraphite pachayo uye kune mabasa ese nehunhu hwegraphite. Nekuti graphite yakadaro ine kuchena kwakanyanya, inonziwographite yakachena kwazvo, uye tsvimbo yegirafiti yakagadzirwa inonziwo tsvimbo yegirafiti yakachena kwazvo.
