Chifukwa Chiyani Mumayanjana Nafe?

Mukatisankha, mumapeza zambiri kuposa zomwe mumapeza - mumapeza mnzanu.

• ukatswiri: Zaka zambiri zazaka zambiri pantchito yoyambira.
• Kusintha Mwamakonda: Mayankho opangidwa kuti akwaniritse zosowa zanu zenizeni.
• Thandizo: Kuyambira kusankha mpaka kukhazikitsa, tili nanu njira iliyonse.

Carbon Crucible ndi ngwazi zosawerengeka zakuponya zitsulo. M'malo mwake, amagwira ntchito yofunika kwambiri pothana ndi zovuta zina zomwe zimasungunuka kwambiri m'malo oyambira komanso malo otentha kwambiri. Kodi mumadziwa kuti ma crucibles awa amatha kupirira kutentha kopitilira 1600 ° C? Izi sizinthu zazing'ono! Kukhalitsa kwawo, kuphatikizidwa ndi matenthedwe apadera amafuta, kumawapangitsa kukhala ofunikira kwambiri mdziko lazitsulo.

1. Mbali zazikulu zaKusungunula Metal Crucibles

• Kulimbana ndi Kutentha Kwambiri: Zapangidwa kuti zipirire kutentha kwakukulu, zitsulo zosungunuka zazitsulo zimapangidwa kuti zigwirizane ndi zofunikira za zitsulo zosiyanasiyana, kuonetsetsa chitetezo ndi mphamvu.
• Kutentha Kwabwino Kwambiri: Zida zomwe zimagwiritsidwa ntchito zimalimbikitsa kugawa kutentha mwachangu komanso kofanana, kuchepetsa nthawi yosungunuka komanso kugwiritsa ntchito mphamvu.
• Kukaniza kwa Corrosion: Ndi zida zomwe zimalimbana ndi oxidation ndi kuukira kwa mankhwala, ma crucibles awa amatalikitsa moyo wautumiki, zomwe zimatanthawuza kupulumutsa ndalama pakapita nthawi.
• Low Coefficient of Thermal Expansion: Khalidweli limachepetsa chiopsezo cha kusweka panthawi yanjinga yotentha, kuwonetsetsa kudalirika pakusungunuka.
• Khoma Lamkati Losalala: Chojambulachi chimalepheretsa zitsulo kuti zisamamatire pamwamba pa crucible, kumathandizira kuthira komanso kuyeretsa mosavuta.2. Zosankha Zopangira Zopangira Zitsulo Zosungunuka
  Posankha chitsulo chosungunuka, ganizirani zinthu zotsatirazi:
  • Silicon Carbide Graphite: Nkhaniyi imapereka matenthedwe apamwamba kwambiri ndipo imalimbana kwambiri ndi kugwedezeka kwamafuta, ndikupangitsa kuti ikhale yabwino kwa ogwiritsa ntchito kutentha kwambiri. Ndiwothandiza makamaka m'malo osungunuka a induction.
  • Clay Graphite: Amadziwika kuti ndi olimba komanso okwera mtengo, ma graphite crucibles a dongo ndi oyenera kusungunula zolinga zonse. Amapereka matenthedwe abwino opangira matenthedwe ndipo amagwiritsidwa ntchito nthawi zambiri m'machitidwe achikhalidwe.
  • Graphite Yoyera: Yodziwika bwino chifukwa cha matenthedwe ake abwino komanso magetsi, ma graphite crucibles ndi abwino kwa mapulogalamu omwe amafunikira kulondola kwambiri komanso kuipitsidwa kochepa. Amachita bwino kwambiri m'malo otentha kwambiri ndipo amathandiza kwambiri zitsulo zamtengo wapatali.

  3. Kugwirizana ndi Mitundu ya Ng'anjo
  Mitsuko yachitsulo yosungunuka imakhala yosunthika ndipo imatha kugwiritsidwa ntchito mumitundu yosiyanasiyana yang'anjo, kuphatikiza:

  • Ma Induction Furnaces: Ndioyenera kuwongolera bwino kutentha kosungunuka, kuwapangitsa kukhala abwino kuponya zitsulo zapamwamba kwambiri.
  • Resistance Furnaces: Ng'anjozi zimapereka malo okhazikika, ofunikira kuti asungunuke mosasintha.
  • Vuto la Vacuum: Zofunikira pazida zovutirapo, ng'anjozi zimachepetsa kuwopsa kwa okosijeni komanso kuipitsidwa.
