Yiziphi izindlela ezivame ukusetshenziswa zokucisha imishini yokuqeda imvamisa ephezulu

Izindlela ezivame ukusetshenziswa zokucisha imishini yokucisha imvamisa ephezulu yilezi:

1. Ukucima okukodwa okuphakathi

Inzuzo ye-single-medium quenching ukuthi kulula ukuyisebenzisa, kodwa ifaneleka kuphela ama-workpieces amancane amancane futhi alula, futhi ijwayele ukuguqulwa okukhulu kanye nokuqhekeka kwama-workpieces amakhulu.

2. Ukucisha okuphakathi kabili

Ukucisha okubili okuphakathi nendawo okokushisa umsebenzi ukuze wenze i-austenitize bese uwucwilisa endaweni enekhono eliqinile lokupholisa. Uma ukuguqulwa kwesakhiwo se-martensite sekuzokwenzeka, sidluliselwa ngokushesha endaweni enekhono lokupholisa elibuthakathaka ukuze kuqhubeke ukupholisa. Ngokuvamile, amanzi asetshenziswa njengendawo yokucisha epholisa ngokushesha, futhi uwoyela usetshenziswa njengendawo yokucisha epholisa kancane. Kwesinye isikhathi ukucisha amanzi kanye nokupholisa umoya kungasetshenziswa. Ukucisha okuphakathi kabili kungavimbela kangcono ukuwohloka nokuqhekeka kwengcezu yokusebenza. Ama-workpieces amakhulu e-carbon steel afanele ukucisha ngale ndlela.

3, ukuqedwa kwezigaba

Le ndlela yokucisha inciphisa kakhulu amandla okucisha ngenxa yokushisa okufanayo ngaphakathi nangaphandle kwendawo yokusebenza futhi iqeda ukuguqulwa kwe-martensitic ngaphansi kwezimo zokupholisa kancane, ngaleyo ndlela inciphisa ngempumelelo noma ivimbele ukuguqulwa nokuqhekeka kwe-workpiece, futhi iphinde inqobe ubunzima bokulawula amanzi. namafutha ekucimeni okukabili-okuphakathi. Ukushiyeka. Kodwa-ke, ngenxa yokushisa okuphezulu kwendawo yokupholisa kule ndlela yokucisha, izinga lokupholisa le-workpiece kubhavu we-alkali noma okugeza okusawoti lihamba kancane, ngakho-ke isikhathi sokulinda sinqunyelwe, futhi kunzima ukuthi izingxenye zesigaba esikhulu finyelela izinga elibalulekile lokucisha. umsebenzi omncane.

4. Ukucinywa kwe-Isothermal

I-Austempering inganciphisa ngokuphawulekayo ukuwohloka nokuqhekeka kwama-workpieces, futhi ifanele ukucubungula izingxenye eziyinkimbinkimbi, ezinembayo nezibalulekile ezibalulekile, njengezikhunta, amathuluzi namagiya. Njengokucisha okuhleliwe, ukucisha i-isothermal kungasetshenziswa kuphela ezintweni zokusebenza ezincane. Ithuluzi lomshini wokucisha imvamisa emaphakathi kanye nephezulu kufanele linqume ukuthi iyiphi indlela yokucisha ozoyisebenzisa ngokuya ngocezu lokusebenza okudingeka ulucime. Amathuluzi amancane nawo angafinyelelwa ngokucisha imidiya eyodwa.

Ngaphezu kwalezi zindlela zokucisha ezingenhla ohlelweni lokucisha amathuluzi omshini wokucisha ama-high-frequency, izinqubo eziningi ezintsha zokucisha ziye zathuthukiswa ukuze kuthuthukiswe amandla nokuqina kwensimbi eminyakeni yamuva nje, njengokucisha izinga lokushisa eliphezulu, ukucisha ukushisa kwe-cyclic ngokushesha, njll.
