Lo msesane wokubumba ubandakanya ukufogina okufana neringi esembindini, i-fan ring, iringi encinci yokutywina, kunye neringi yocinezelo yetanki yamanzi yesikhululo samandla sejenereyitha yeinjini yeinjini, kodwa ayifanelanga ukufogiswa kweringi engeyiyo eyemagnetic.
Inkqubo yokwenziwa kwemveliso:
1 Ukunyibilika
1.1. Intsimbi esetyenziselwa ukukhwabanisa kufuneka inyibilikiswe kwiziko lombane le-alkaline. Ngemvume yomthengi, ezinye iindlela zokunyibilikisa ezifana ne-electro-slag remelting (ESR) nazo zingasetyenziswa.
1.2. Xa kusenziwa imigangatho yebanga lesi-4 okanye ngaphezulu kunye nebanga lesi-3 ubukhulu bodonga obungaphezulu kwe-63.5mm, intsimbi etyhidiweyo esetyenzisiweyo kufuneka icocwe ngevacuum okanye icocwe ngezinye iindlela zokususa iigesi eziyingozi, ngakumbi i-hydrogen.
2 Ukubumba
2.1. Ingot nganye yensimbi kufuneka ibe nesibonelelo esaneleyo sokusika ukuze kuqinisekiswe umgangatho wokubumba.
2.2. I-Forgings kufuneka yenziwe kwi-forging presses, i-forging ihamile, okanye i-rolling Mills enomthamo owaneleyo wokuqinisekisa ukubunjwa okupheleleyo kwecandelo elinqamlezayo lesinyithi kunye nokuqinisekisa ukuba icandelo ngalinye linomlinganiselo owaneleyo wokubumba.
3 Unyango lobushushu
3.1. Emva kokuba i-forging igqityiwe, i-forging kufuneka ifakwe ngokukhawuleza kunyango lwangaphambi kokushisa, olunokuthi lube ne-annealing okanye luqhelekileyo.
3.2. Unyango lobushushu bokusebenza lucima kwaye luvutha (i-16Mn inokusebenzisa i-normalization kunye ne- tempering). Ubushushu bokugqibela bobushushu bokwenza izinto akufunekanga bube ngaphantsi kwe 560℃.
4 Ukwakhiwa kweekhemikhali
4.1. Uhlalutyo lokubunjwa kweekhemikhali kufuneka lwenziwe kwibhetshi nganye yensimbi etyhidiweyo, kwaye iziphumo zokuhlalutya kufuneka zihambelane nemigangatho efanelekileyo.
4.2. Uhlalutyo lwemveliso yeekhemikhali ezigqityiweyo kufuneka lwenziwe kwi-forging nganye, kwaye iziphumo zokuhlalutya kufuneka zihambelane nemigangatho efanelekileyo. 4.3. Xa i-vacuum decarburizing, umxholo we-silicon akufanele udlule i-0.10%. 4.4. Kwibakala lesi-3 i-ring forgings kunye nobukhulu bodonga obungaphezulu kwe-63.5mm, izinto ezinomxholo we-nickel ezingaphezu kwe-0.85% kufuneka zikhethwe.
5 Iimpawu zoomatshini
5.1. Iimpawu ze-tangential mechanical of the forgings kufuneka zihambelane nemigangatho efanelekileyo.
6 Uvavanyo olungonakalisi
6.1. I-forgings akufanele ibe neentanda, i-scars, i-folds, imingxuma eyanciphayo, okanye ezinye iziphene ezingavumelekanga.
6.2. Emva komatshini ochanekileyo, yonke imiphezulu kufuneka ihlolwe ngamasuntswana omagnetic. Ubude bomgca wemagnethi akufanele budlule i-2mm.
6.3. Emva kokusebenza kwonyango lobushushu, i-forgings kufuneka iqhube uvavanyo lwe-ultrasonic. Idayamitha elinganayo yobuntununtunu kufuneka ibe yi-φ2 mm, kwaye isiphene esinye akufanele sigqithise i-diameter elinganayo φ4mm. Kwisiphene esinye phakathi kwedayamitha ezilinganayo ze-φ2mm~¢4mm, akufuneki kubekho iziphene ezingaphezu kwesixhenxe, kodwa umgama phakathi kwazo naziphi na iziphene ezibini ezimeleneyo kufuneka ube mkhulu kunophinda-phindwe kahlanu kunodayamitha enkulu yesiphene, kwaye ixabiso lokuthomalalisa okubangelwa ziziphene akufuneki libe likhulu. ngaphezulu kwe-6 dB. Iziphene ezidlula le migangatho ingentla kufuneka zixelwe kumthengi, kwaye omabini amaqela kufuneka abonisane malunga nokuphatha.
