Nekuda kwekusimba kwakasimba kwezvinhu zvinoumbwa zvemanganese yakakwira uye alloy simbi, alloy isingapfeki nekuoma kwakasimba inogona kukwiridzirwa pamusoro, kuitira kuti simba repamusoro rezino rebucket rivandudzwe zvakanyanya, kuitira kuti uwane mamwe. yakanakira bhaketi zino.Nekuda kwekuti ine misimboti yakasimba mukugadzirisa kusanaya kwemvura, kuvharidzira masimbi alloys ane kuomarara kwakanyanya uye kwakanaka kupfeka kuramba kunofanirwa kusarudzwa muzvinyorwa.
Zvinoenderana nezvidzidzo zvakakodzera, iyo yakakwira iron alloy ine yakasimba kupfeka kuramba kupfuura iyo yakakwira manganese simbi zvinhu, uye iyo yakakwira iron alloy kana martensitic cast iron alloy inoshandiswa mukugadzira mazino matsva emubhaketi uye kugadziriswa kwemazino ekare ebhaketi.Pakugadzirisa kurapwa, murazvo weacetylene unogona kutemwa nemuromo wezino rekare remubhaketi, uchisiya imwe groove, wobva washandisa austenitic simbi manganese welding tsvimbo kugadzira inowirirana yechimiro chepakutanga, uye pakupedzisira kufukidzira welding kurapwa pamusoro. kuvandudza kusamira kwekupfeka kwevacheri vakakura mumigodhi.

Kutanga, nzira yekucheka
Kana zino remubhakiti rinosangana nedombo (ore) pasi pemutoro wepamusoro, kune rumwe rutivi, rinosangana nedombo (ore) pamusoro uye rinogadzira simba guru rekuita, kana simba regoho rezino rebhaketi rakaderera. muromo wezino remubhaketi unoburitsa imwe purasitiki deformation, iyo iri nyore kugadzira furrow yepurasitiki.Ukuwo, kana zino remugomo rinopinzwa mudombo (ore), kana kuoma kwezino remugomo kwakadzikira pane kuoma kwedombo (ore), matombo (ore) zvidimbu zvinosundirwa pamusoro pedombo. bucket zino, iro rinogadzira machipisi marefu muchimiro checurve kana spiral, ichigadzira groove yekucheka, iyo inogona kuperekedzwa ne micro cutting chips.Chip nekuda kwekugera chiito uye nhamba huru ye deformation, inobereka yakawanda deformation yakadzikama kupisa, inoratidzika padyo uye yakarongeka yakarongeka inotsvedza nhanho, kuumbwa kwemakwinya, kuwedzera, kukwesha kwayo nedombo (ore) kuburitsa kupisa kwefriction, deformation. Kupisa kwakadzikama uye kupisa kwekukwenya kwakasanganiswa kuita kuti tembiricha yechip ikwire zvakanyanya, dynamic recrystallization, tempering kupfava, shanduko yechikamu chekuchinja, nezvimwewo, shandura chimiro chemukati chechip, zvimwewo zvinoonekwa zvekunyunguduka kwenzvimbo.
Chechipiri, kuneta peeling mechanism
Zino remugomo rinoiswa mudombo (ore) kuti ridzokere, uye mugero weplastic gejo wakaumbwa pamusoro unopwanywa nematombo ematombo ari kumusoro kwenguva yakawanda, anogona kugadzira tafura yesimbi yakawanda-kuyerera, uye kutsemuka uye kutsemuka. ichagadzirwa apo kushushikana kweiyo bucket zino zvinhu kunodarika muganhu wesimba.Yekutanga yakatsemuka perpendicular kune yekupfeka gwara, uye imwe yacho yakatsemuka kana kubvarurwa pasi nzira yekupfeka, ine yakatsetseka grooved mitsetse kudivi remberi, yakapfava kumusana, uye mitsetse inopindirana inoumbwa nekupwanya deformation pamativi.Kana dombo racho rikakona, rinoveura deformation layer uye kuumba marara, ayo akati sandara uye anoputika ane rough edges.Panewo mamiriro ezvinhu, apo zino rebhaketi uye dombo rinoramba richiita, iyo bhaketi zino repurasitiki deformation uye rinokonzera basa rakakwirira rekuomesa, kuitira kuti zino rezino rezino rive brittle, pasi pesimba rakasimba redombo, the mazino epamusoro anozogadzira brittle chips, uye nzvimbo yaro ine radial makatsemuka ezvakadzika zvakasiyana.Ichi brittle cracking character is also strictly a fatigue flaking mechanism.Kupfeka kusashanda kwemaitiro kunoenderana nezvinhu uye mamiriro ekushanda, kunyanya kusanganisira kucheka, kuneta kupepeta uye mamwe maitiro.Kazhinji kutaura, nzira yekucheka inotonga kuparara kwekupfeka kwemazino ebhakiti, inosvika kupfuura 7O;Nekuwedzera kwekuoma kwemazino emubhakiti, kuneta kwekutsvaira nzira kwakawedzera zvishoma nezvishoma, kuverenga kwe2O ~ 3O;Kana kuoma kwezvinhu kunosvika kumucheto wepamusoro, brittleness inowedzera uye brittle chipping inogona kuitika.Nokuda kwemamiriro ekushanda anotungamirirwa nemaitiro ekucheka, kuvandudza kuoma kwebhakiti zino zvinhu zvinobatsira kuvandudza kusakara kwayo;Kune iyo kuneta peeling michina, iyo zvinhu zvinodiwa kuti ive yakanaka yakaoma uye yakaoma kukwana;High kuoma, kusimba kwakanyanya kwekutsemuka, kuderera kwekukura kwekuwedzera uye kukwirira kwekuneta kwekuramba zvese zvinobatsira mukuvandudza kusakara kwemidziyo.
