ma crucibles amapangidwa ndi chiyani?

Kapangidwe kacruciblezipangizo ndi kufunika kwawo mu zitsulo

Crucible ndi chida chofunikira kwambiri pamakampani opanga zitsulo, chomwe chimagwiritsidwa ntchito kukhala ndi kutenthetsa zitsulo ndi ma aloyi osiyanasiyana. Komabe, mawonekedwe a crucible amakhudza mwachindunji ntchito yake ndi moyo m'malo otentha kwambiri. Choncho, kumvetsetsa kapangidwe ka crucible ndikofunika kwambiri kuti musankhe crucible yoyenera kuti mugwiritse ntchito zitsulo. Nkhaniyi ifufuza zigawo zazikulu za crucibles ndi kufunikira kwake muzitsulo zazitsulo.

1. Graphite crucible
Graphite crucible ndi imodzi mwa mitundu yodziwika kwambiri. Chifukwa cha kukana kwake kutentha kwambiri komanso kukhazikika kwa mankhwala, amagwiritsidwa ntchito kwambiri posungunula zitsulo zopanda chitsulo monga aluminiyamu, mkuwa, ndi golide. Chigawo chachikulu cha graphite crucible ndi carbon, yomwe imakhala ndi matenthedwe abwino kwambiri, omwe amalola zitsulo kutenthedwa mofulumira komanso mofanana, motero kuchepetsa nthawi yosungunuka. Kuphatikiza apo, graphite crucible imakhala yabwino kukana dzimbiri ndipo imatha kupirira kukokoloka kwa zinthu zambiri za acidic ndi zamchere zosungunuka.

2.Silicon carbide crucible
Ma silicon carbide crucibles amakondedwa ndi mafakitale azitsulo chifukwa cha kuuma kwawo kwakukulu komanso kukana kwa okosijeni. Silicon carbide ndi chinthu cholimba kwambiri chomwe chimatha kupirira kutentha kwambiri popanda kupunduka. Poyerekeza ndi ma graphite crucibles, silicon carbide crucibles imakhala ndi moyo wautali wautumiki ndipo ndi yoyenera kwambiri kusungunuka kwachitsulo, chitsulo ndi zitsulo zina zotentha kwambiri. Kuphatikiza apo, zinthu za silicon carbide zimakhala ndi kukhazikika kwamphamvu kwamafuta, kumachepetsa chiopsezo cha kuwonongeka kwa crucible chifukwa chakusintha kwachangu kwa kutentha.

3. Ceramic crucible
Ma crucibles a ceramic amapangidwa makamaka ndi zida za ceramic monga alumina ndi zirconia. Ma crucibles awa amawonetsa kusakhazikika kwamankhwala ndipo ndi oyenera kukonza zitsulo ndi ma aloyi omwe amawononga kwambiri zida zina. Malo osungunuka a ceramic crucibles amawathandiza kukhala okhazikika pansi pa kutentha kwambiri ndipo amagwiritsidwa ntchito kwambiri m'ma laboratories ndi ntchito zina zapadera za mafakitale. Komabe, ma crucibles a ceramic ndi opepuka kwambiri ndipo amafunikira kusamala mosamala akamagwiritsidwa ntchito kuti apewe kusweka chifukwa champhamvu yamakina.

4. Chitsulo crucible
Zitsulo zachitsulo zimagwiritsidwa ntchito kwambiri posungunula zitsulo zazikulu, monga maziko. Ma crucibles achitsulo nthawi zambiri amapangidwa ndi zitsulo zosagwira kutentha ndipo amakhala ndi mphamvu zamakina komanso kukana kutentha kwambiri. Ngakhale ma crucibles achitsulo sakhala otenthetsera ngati ma graphite crucibles, amatha kupirira kugwedezeka kwakuthupi, kuwapangitsa kukhala oyenera kusungunula ntchito zomwe zimafuna kutsitsa pafupipafupi ndikutsitsa kapena kusamutsa.

5. Zida zina
Kuphatikiza pa zida zomwe zatchulidwa pamwambapa, palinso zida zapadera zomwe zimagwiritsidwa ntchito pazinthu zinazake. Mwachitsanzo, ma tungsten crucibles amagwiritsidwa ntchito poyesera kutentha kwambiri chifukwa cha malo osungunuka kwambiri komanso kukana kwa dzimbiri. Titaniyamu crucibles amagwiritsidwa ntchito kusungunula ma aloyi apadera chifukwa sachita ndi zitsulo zambiri.

Pomaliza
Zomwe zimapangidwa ndi crucible sizimangotsimikizira kukhazikika kwake komanso kukhazikika kwake m'malo otentha kwambiri, komanso zimakhudza mwachindunji magwiridwe antchito ndi chitetezo cha smelting. Choncho, posankha crucible, katundu wa mankhwala, matenthedwe matenthedwe, mphamvu zamakina ndi moyo wautumiki ziyenera kuganiziridwa potengera zofunikira za ntchito. Ma Crucibles azinthu zosiyanasiyana amatenga gawo losasinthika mumakampani opanga zitsulo, kupereka chitsimikizo chodalirika cha kukonza zitsulo koyenera komanso kotetezeka.
