Basa re graphite mold mu brazing

Graphite molds inoita basa rakakosha mukubhuroka, kunyanya kusanganisira zvinotevera zvinhu:

• Yakagadziriswa uye yakarongedzwa kuti ive nechokwadi chokuti weldment inochengetedza nzvimbo yakagadzikana panguva yekugadzira, ichidzivirira kubva pakufamba kana kukanganisa, nekudaro kuve nechokwadi chekururama uye hutano hwekushongedza.
  Kupisa kwekushisa uye kutonga kwekushisa Nokuti graphite ine yakanaka yekupisa conductivity, inogona kukurumidza uye yakaenzana kuendesa kupisa, iyo inobatsira kudzora kugoverwa kwekushisa panguva yekugadzirwa kwebrazing, kuitira kuti zvinhu zvinoputika zvinogona kunyunguduka zvakakwana uye kuzadza weld kuti iwane kubatana kwakanaka.
  Kugadzira chimiro chaicho uye chimiro Inogona kugadzirwa mune chaiyo chimiro uye chimiro sezvinodiwa kubatsira kuumba welding joint uye weldment shape inoenderana nezvinodiwa.
  Dziviriro mhedzisiro Inopa imwe dziviriro kune weldment uye inoderedza kupindira uye pesvedzero yekunze kwezvakatipoteredza pane brazing process, sekudzivirira oxidation.

Graphite molds ine akawanda akakosha mabhenefiti ekubhuroka:

• Excellent thermal conductivity Inogona kukurumidza kutamisa kupisa, kuita kuti brazing zvinhu zvinyunguduke zvakaenzana, kuvandudza kushanda uye kunaka kwekubatana.
  Kugadzikana kwekemikari yepamusoro Hazvisi nyore kugadzirisa kemikari nezvinhu zvebrazing uye weldment, kuve nechokwadi chekuchena uye kugadzikana kwekugadzirisa.
  Mutengo wakaderera Kana uchienzaniswa nezvimwe zvinhu zvinodzivirira tembiricha yepamusoro, mutengo wezviumbwa zvematombo une mari shoma, izvo zvinobatsira kudzikisa mutengo wekugadzira.

Graphite molds ine simba rakakosha pamhando yebrazing:

• Kukanganisa kuzadza kweiyo weld
  Iyo yakakodzera graphite mold inogona kuve nechokwadi chekuti iyo brazing inozadza zvizere weld, ichigadzira yunifomu uye dense welded joint, uye kuvandudza kusimba uye chisimbiso chejoini.
  Sarudza iyo microstructure yejoinhi
  Iko kupisa kwekushisa kwekuita uye chimiro che mold inokanganisa kugovera kwekushisa uye kutonhora kwehuwandu panguva yekugadzira brazing, nekudaro ichikanganisa microstructure uye kushanda kwejoini.
  Inokanganisa kurongeka kwedimensional ye weldment
  Iko kurongeka kwe mold kunoenderana zvakananga neiyo dimensional kurongeka kweiyo weldment. Kana iyo mold iko kusiri kwakakwira, inogona kukonzera dimensional kutsauka kweiyo weldment uye kukanganisa kuita kwayo.
