Iivalvu ezifakwayo zinokubangela iziphene

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 ukufunyanwa ngokuchongwa kwe-ultrasound.

2. Isilayidi se-slag

I-slag kwinkqubo yokunyibilikisa okanye i-refractory emzimbeni wesithando ihluba isinyithi esilulwelo, kwaye ibandakanyeka 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.

3. 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.

4. Jika ulusu

Oku kwenziwa ngentsimbi ukusuka kwiladle ukuya kwi-ingot casting ingot, ngenxa yokuthulula ukuphazamiseka, ikhefu, egalelwe kumphezulu wesinyithi esilulwelo emoyeni, ifom ye-oxide epholileyo ngokukhawuleza, ukuthululwa okutsha kwisinyithi esilulwelo kuya kuqhekeza emzimbeni we-ingot kwaye kwenze iziphene (indawo) ezihambelanayo, oko kukwenza i-ingot billet elandelayo ayikwenzi.

5. I-Anisotropy

Xa i-casting okanye i-ingot ipholisiwe kwaye iqina, isantya sokupholisa ukusuka kumphezulu ukuya embindini siyahluka, ngoko ke kuya kwakheka i-crystallization tissue eyahlukileyo, ebonisa i-anisotropy yeempawu zoomatshini, kwaye ikwakhokelela kwi-anisotropy yeempawu ze-acoustic, oko kukuthi, kukho isantya sesandi esahlukileyo kunye nokuncitshiswa kwesandi ukusuka embindini ukuya kumphezulu. Ubukho bale anisotropy bunokuba nefuthe elibi kubungakanani kunye nendawo yeziphene ezivavanyiweyo ngexesha lokufunyanwa kwe-ultrasonic.
