Na 45# tšepe e hloka ho halefa?
Na 45# tšepe e hloka ho halefa?
Tlhokahalo ea ho halefa ho eketsehileng e khethoa ke boemo. Haeba mocheso o setseng oa mocheso o ka laoloa nakong ea ho tima, ha ho hlokahale hore ho be le mocheso o eketsehileng oa mocheso o tlaase.
Sebopeho le thepa ea 45 # tšepe ka mor’a annealing, normalizing, quenching le tempering.
45# tšepe annealing: ferrite + pearlite;
45 # tšepe e tloaelehileng: ferrite + pearlite;
45 # ho tima tšepe: martensite;
45 # ho futhumatsa tšepe: martensite e halefileng (mocheso o tlase oa mocheso), troostite e futhumetseng (mocheso o mahareng), sorbite e futhumetseng (mocheso o phahameng oa mocheso).
Sebopeho sa tšepe ea 45 # kamora ho tloaeleha ke sebopeho sa ferrite + pearlite, sebopeho ka mor’a ho tima ke sebopeho sa martensite, le sebopeho ka mora ho tima + 400 ℃ mocheso ke sebopeho sa troostite se futhumetseng. The normalizing performance hardness e ka tlase ho HB200, empa thepa e bonolo ho etsoa machined, e ntseng e le morero oa mantlha oa ts’ebetso. Ho tima +400 ℃ boima ba ho futhumatsa bo botle haholo, ka holimo ho HB300.
Ho thatafala ha 45# tšepe e tingoeng le ho halefa ke pakeng tsa HRC20~HRC30;
Boima ba ho tima ba 45 # tšepe bo pakeng tsa HRC55 ~ 58, ‘me boleng bo ka fihla HRC62;
Ho nka matsatsi a 15-20 hore tšepe ea 45 # e sebelisoe hobane e hloka phekolo ea botsofali ho tsitsisa ts’ebetso ea tšepe.
Bothata bo phahameng ka ho fetisisa ts’ebetsong e sebetsang ke HRC55 (high-frequency quenching HRC58).
45 # tšepe ke tšepe ea boleng bo holimo ea khabone e nang le boima bo tlase le ts’ebetso e bonolo ea ho itšeha. E sebelisoa hangata ka har’a hlobo e le litempele, malebela, li-post tsa tataiso, joalo-joalo, empa kalafo ea mocheso e ea hlokahala.
