Indlela yokuqhuba unyango lwe-post-forging heat forgings

Kuyimfuneko ukuqhuba unyango lobushushu emvaukwenzakuba injongo yayo kukuphelisa uxinzelelo lwangaphakathi emva kokubumba. Lungisa ubulukhuni bokubumba, ukuphucula ukusebenza kokusika; Iinkozo ezirhabaxa kwinkqubo yokubumba zisulungekile kwaye zifanayo ukulungiselela i-microstructure yamacandelo onyango lobushushu.

1. Ukushisa okuphezulu kweqondo lokushisa: ukunciphisa ubunzima, ukunciphisa okanye ukuphelisa uxinzelelo oluveliswayo xa upholisa okuqhelekileyo, ukuphucula iplastiki kunye nokuqina. Ifanelekile kwintsimbi ye-alloy enobunzima obuphezulu emva kokuqhelekileyo.

2. I-annealing epheleleyo: ukuphelisa isakhiwo esinqabileyo kunye nokungalingani okubangelwa yinkqubo yokubumba, ukucokisa ingqolowa, ukuphelisa uxinzelelo olushiyekileyo lwe-forging, ukunciphisa ukuqina, ukuphucula ukucwangciswa, kunye nokulungiselela umbutho wonyango lwexesha elizayo lwamalungu. I-annealing epheleleyo ifanelekile ngokubanzi kwintsimbi ye-hypoeutectoid.

3. I-annealing ye-Isothermal: fumana isakhiwo esifanayo ngakumbi kunokuba i-annealing epheleleyo, ukuphelisa ngokufanelekileyo ukuxinzezeleka koxinzelelo, ukunciphisa ubunzima. Kwiifogi ezibalulekileyo ezinkulu, zingasetyenziselwa ukusasaza i-hydrogen kunye nokuthintela ukuveliswa kwamabala amhlophe. Xa kuthelekiswa ne-annealing epheleleyo, inokunciphisa ixesha lokufunxa kwaye iphucule ukusebenza kakuhle kwemveliso.

4. Ukulungelelanisa: i-pearlite ecolekileyo inokufumaneka ukucokisa umbutho; Phuculaforgingsamandla kunye nokuqina, ukunciphisa uxinzelelo lwangaphakathi, ukuphucula ukusebenza kokusika; Ngentsimbi ye-eutectoid. I-Mesh carbides inokupheliswa.

I-5 spheroidization annealing: ukufumana i-cementite ye-spherical kunye nesakhiwo se-ferrite, kungekhona nje ukunciphisa ubulukhuni, kwaye kwinkqubo yokusika kulula ukufumana umgangatho wokucubungula ogudileyo, ekucimeni okulandelayo akulula ukuvelisa iintanda ze-deformation. I-Spheroidizing annealing ifanelekile kwintsimbi yekhabhoni ephezulu kunye nentsimbi ephezulu ye-carbon alloy die steel.
