Ziziphi iziphene ezibangelwa kukuphoswa kwevalvu?

1. I-stomata

Le yingxinano encinci eyenziwe yigesi apho inkqubo yokuqina kwesinyithi ingaphumi ngaphakathi kwesinyithi. Udonga lwayo lwangaphakathi lugudileyo kwaye luqulathe igesi, enokugqama okuphezulu kwi-ultrasound wave, kodwa ngenxa yokuba ngokusisiseko iyingqukuva okanye i-ellipsoid, sisiphene senqaku, esichaphazela ubukhulu bayo bokugqama. Umngxuma womoya kwi-ingot uthambekiswa ube sisiphene sendawo emva kokubumba okanye ukuqengqeleka, okuluncedo ukufunyaniswa ngokuhlolwa kwe-ultrasound.

2. Ukurhoxa kunye nomngxuma okhululekileyo

Xa i-casting okanye i-ingot ipholisiwe kwaye iqina, ivolumu kufuneka inciphe, kwaye isiphene esingenanto asinakongezwa yintsimbi engamanzi. Ii-vovities ezinkulu nezixineneyo zibizwa ngokuba yimingxuma yokuncibilika, kwaye ii-voids ezincinci nezisasazekileyo zibizwa ngokuba zikhululekile. Ngenxa yomthetho wokwandiswa kobushushu kunye nokuncibilika okubandayo, umngxuma wokuncibilika uya kubakho, kodwa kukho iimilo ezahlukeneyo, ubungakanani kunye nezikhundla ezineendlela ezahlukeneyo zokucubungula, kwaye uba sisiphene xa ufikelela emzimbeni wokuncibilika okanye we-ingot. Ukuba i-ingot ayiwunqumli umngxuma wokuncibilika ucocekile kwaye uyizise kwiindawo zokubumba, iya kuba ngumngxuma wokuncibilika oseleyo (umngxuma wokuncibilika oseleyo, umbhobho wokuncibilika oseleyo).

3. Isilayidi se-slag

I-slag kwinkqubo yokunyibilikisa okanye i-refractory emzimbeni wesithando ikrazula kwisinyithi esilulwelo, kwaye itsalwa kwi-casting okanye kwi-ingot yentsimbi xa igalelwa, okwenza isiphene se-slag clamp. I-slag ayihlali yodwa, idla ngokuba kwimeko exineneyo okanye isasazeke kubunzulu obahlukeneyo, ifana neziphene zomthamo kodwa idla ngokuba nomgca othile.

4. Ixutyiwe

Iimveliso zempendulo kwinkqubo yokunyibilikisa (ezifana ne-oxide, i-sulfide, njl.njl.) -izinto ezingezizo zesinyithi, okanye izinto ezongeziweyo zezinye izinto kwizixhobo zesinyithi azinyibiliki ngokupheleleyo kwaye zihlala zenze izinto ezihlanganisiweyo zesinyithi, ezifana noxinano olukhulu, izinto ezinamaqondo aphezulu okunyibilikisa - i-tungsten, i-molybdenum, njl.njl.

5. Ushwankathelo lwamagama

Ukwahlulwahlulwa kwi-casting okanye kwi-ingot kubhekisa ikakhulu kukwahlulwahlulwa kwezakhi ezakhiwe kulwabiwo olungalinganiyo lwezakhi kwinkqubo yokunyibilikisa okanye kwinkqubo yokunyibilikisa isinyithi. Iipropati zoomatshini zendawo enokwahlulwahlulwa zahlukile kwiipropati zoomatshini ze-matrix yesinyithi iyonke, kwaye umahluko ngaphaya koluhlu oluqhelekileyo oluvumelekileyo uba sisiphene.

6. Ukuphosa imifantu

Ukuqhekeka kwi-casting kubangelwa kakhulu kukuxinana koxinzelelo lokuqina kokupholisa isinyithi kudlula amandla okugqibela ezinto, kunxulumene nokuma koyilo lwe-casting kunye nenkqubo ye-casting, kwaye kunxulumene nokuziva ubuthathaka kokuqhekeka kwezinye izinto zesinyithi (ezifana nomxholo ophezulu wesalfure, ukubuthathaka okubandayo, umxholo ophezulu we-phosphorus, njl.njl.). Kwi-spindle, kuya kubakho ukuqhekeka kwi-shaft crystal, kwaye kwi-billet forging elandelayo, iya kuhlala kwi-forging njenge-crack yangaphakathi ye-forging.
