Uhlolojikelele lwe-Bearing Steel

Insimbi yokuthwala isetshenziselwa ukwenza amabhola, ama-roller namasongo okuzala.I-Bearing steel inokuqina okuphezulu nokufana okufanayo, ukumelana nokugqoka kanye nomkhawulo ophezulu wokunwebeka.Izidingo zokufana kokwakheka kwamakhemikhali, okuqukethwe kanye nokusatshalaliswa kwe-non-metallic inclusions, kanye nokusatshalaliswa kwama-carbides ensimbi enensimbi kuqinile kakhulu.Ingelinye lamabanga ensimbi aqine kakhulu kukho konke ukukhiqizwa kwensimbi.

Amamaki ensimbi ezinsimbi ezithwalayo ezivamile awuchungechunge lwensimbi olune-carbon chromium ephezulu, njenge-GCr15, Gcr15SiMn, njll. Ngaphezu kwalokho, izinsimbi ezithwala i-carburized, ezifana ne-20CrNi2Mo, 20Cr2Ni4, njll., zingasetshenziswa futhi ngokuvumelana nezimo zokusebenza ezihlukene, ezingenasici. izinsimbi ezinensimbi, njenge-9Cr18, njll., nezinsimbi ezinezinga lokushisa eliphezulu, njenge-Cr4Mo4V, Cr15Mo4V2, njll.

Impahla ebonakalayo

Izakhiwo ezibonakalayo zensimbi enensimbi ikakhulukazi zihlanganisa i-microstructure, isendlalelo se-decarburized, ukufakwa okungeyona insimbi kanye ne-macrostructure.Ngokuvamile, imikhiqizo ilethwa nge-annealing eshisayo egoqayo kanye ne-annealing yomdwebo obandayo.Isimo sokudiliva sizoboniswa kunkontileka.I-macrostructure yensimbi kumele ingabi namgodi wokushwabana, ibhamuza elingaphansi kwesikhumba, indawo emhlophe kanye nembotshana encane.I-porosity emaphakathi kanye ne-porosity evamile akufanele idlule ibanga le-1.5, futhi ukuhlukaniswa akufanele kudlule ibanga lesi-2. Isakhiwo esihlanganisiwe sensimbi sizosatshalaliswa ngokulinganayo i-pearlite enohlamvu oluhle.Ukujula kongqimba lwe-decarburization, inclusions engeyona eyensimbi kanye nokungalingani kwe-carbide kuzothobelana namazinga kazwelonke afanelekile.
