Ukwenziwa kwerotha yeeinjini zomphunga kwishishini

1. Ukunyibilika

1.1 Ukuveliswa kweengxenye ezibunjiweyo, i-alkaline electric arc furnace smelting elandelwa ukucocwa kwangaphandle kunconywa kwiingots zetsimbi.Ezinye iindlela zokuqinisekisa umgangatho nazo zinokusetyenziselwa ukunyibilikisa.

1.2 Ngaphambi okanye ngexesha lokuchithwa kwee-ingots, intsimbi kufuneka iqhube i-vacuum degassing.

2. Ukubumba

2.1 Iimpawu eziphambili ze-deformation ngexesha le-forging process kufuneka ziboniswe kwi-forging process diagram.Isibonelelo esaneleyo sokusika kufuneka sinikezelwe kwiindawo eziphezulu kunye nezisezantsi ze-ingot yensimbi yokuqinisekisa ukuba inxalenye edibeneyo ikhululekile kwi-slag inclusions, i-shrinkage cavities, i-porosity, kunye neziphene ezinzima zokuhlukana.

2.2 Izixhobo zokubumba kufuneka zibe nomthamo owaneleyo wokuqinisekisa ukungena ngokupheleleyo kwecandelo elinqamlezayo.I-axis yecandelo elibunjiweyo kufuneka lilungelelanise ngokusondeleyo ngokusemandleni kunye ne-axial centerline ye-ingot yensimbi, ngokukhethekileyo ukukhetha isiphelo se-ingot yensimbi kunye nomgangatho ongcono we-turbine drive end.

3. Unyango lobushushu

3.1 Unyango lwe-post-forging, normalizing kunye ne- tempering kufuneka lwenziwe.

3.2 Ukusebenza unyango ubushushu kufuneka kwenziwe emva machining rough.

3.3 Ukusebenza kokunyanga ubushushu kubandakanya ukucima kunye nokufudumala kwaye kufuneka kuqhutywe kwindawo ethe nkqo.

3.4 Iqondo lokushisa lokufudumeza ukucima ngexesha lokunyanga ubushushu bokusebenza kufuneka libe ngaphezu kweqondo lokushisa lokuguqulwa kodwa lingadluli kwi-960 ℃.Ubushushu bobushushu akufunekanga bube ngaphantsi kwe 650 ℃, kwaye inxalenye kufuneka ipholiswe kancinci iye ngaphantsi kwe 250 ℃ phambi kokuba isuswe kwiziko.Izinga lokupholisa phambi kokususwa kufuneka libe ngaphantsi kwe-25 ℃/h.

4. Unyango oludambisa uxinzelelo

4.1 Unyango lokunciphisa uxinzelelo kufuneka lwenziwe ngumthengisi, kwaye iqondo lokushisa kufuneka libe phakathi kwe-15 ℃ ukuya kwi-50 ℃ ngaphantsi kweqondo lobushushu langempela.Nangona kunjalo, ubushushu bonyango lokunciphisa uxinzelelo akufunekanga lube ngaphantsi kwama-620 ℃.

4.2 Inxalenye ephothiweyo kufuneka ibe kwindawo ethe nkqo ngexesha lonyango lokunciphisa uxinzelelo.

5. Ukuwelda

I-Welding ayivumelekanga ngexesha lokuvelisa kunye neenkqubo zokupakisha.

6. Ukuhlolwa kunye novavanyo

Isixhobo kunye nekhono lokuqhuba iimvavanyo malunga nokwakheka kweekhemikhali, iipropathi zoomatshini, ukuhlolwa kwe-ultrasonic, uxinzelelo olushiyekileyo, kunye nezinye izinto ezichaziweyo kufuneka zihambelane nezivumelwano zobugcisa ezifanelekileyo kunye nemigangatho.
