Ingabe insimbi engu-45# idinga ukufuthwa?

Isidingo sokuthukuthela okwengeziwe sinqunywa isimo. Uma izinga lokushisa elisele lingalawuleka ngesikhathi sokucisha, asikho isidingo sokufudumeza okwengeziwe kwezinga lokushisa eliphansi.

Isakhiwo kanye izakhiwo 45 # steel ngemva annealing, normalizing, quenching kanye tempering.

45# annealing steel: ferrite + pearlite;

45# insimbi evamile: i-ferrite + pearlite;

45 # ukucisha insimbi: martensite;

I-45# i-steel tempering: i-martensite e- tempered (izinga lokushisa eliphansi lokushisa), i-troostite eqinile (izinga lokushisa eliphakathi nendawo), i-sorbite epholile (izinga lokushisa eliphakeme).

Isakhiwo sensimbi engu-45 # ngemuva kokujwayelekile siyisakhiwo se-ferrite + pearlite, isakhiwo ngemuva kokucisha siyisakhiwo se-martensite, futhi isakhiwo ngemva kokucisha + 400 ℃ ukufudumala kuyisakhiwo se-troostite esithambile. Ukuqina kokusebenza okujwayelekile kungaphansi kwe-HB200, kodwa impahla kulula ukwenziwa ngomshini, okusewuhlelo lwenqubo oluyinhloko. Ukucisha +400℃ ubulukhuni bokushisa kuhle kakhulu, ngaphezu kwe-HB300.

Ubulukhuni bensimbi engu-45# ecishiwe futhi buqinile buphakathi kwe-HRC20~HRC30;

Ukuqina kokucisha kwensimbi engu-45# kuphakathi kwe-HRC55~58, futhi inani lingafinyelela ku-HRC62;

Kuthatha izinsuku ezingu-15-20 ukuze kusetshenziswe insimbi engu-45# ngoba idinga ukwelashwa kokuguga ukuze kuzinze ukusebenza kwensimbi.

Ukuqina okuphezulu kakhulu ekusebenzeni okusebenzayo yi-HRC55 (i-high-frequency quenching HRC58).

I-45# insimbi iyinsimbi yesakhiwo sekhabhoni ephezulu enobulukhuni obuphansi kanye nokucutshungulwa okulula kokusika. Isetshenziswa kakhulu ekubunjweni njengezifanekiso, amathiphu, izigxobo zomhlahlandlela, njll., kodwa ukwelashwa kokushisa kuyadingeka.
