1. Akadzvanywa uye akatsamwa simbi
Muedzo wechiitiko wakadzvanywa uye akatsamwa simbi inonyanya kushandisa rockwell hardness tester hrc chiyero. Kana izvo zvinyorwa zvakaonda uye hrc chiyero hachina kukodzera, hra chiyero chinogona kushandiswa pachinzvimbo. Kana izvo zvinyorwa zvacho zvakaonda, kubva kune mhouwell hardness scales hr15n, hr30n, kana hr45n inogona kushandiswa.
2. Kumusoro kwakaomeswa simbi
Mukugadzirwa kwemaindasitiri, dzimwe nguva kukosha kweiyo basa rekushanda kunodiwa kuti kuve nekuoma kwakanaka, nepo nzvimbo yacho ichidiwa zvakare kuve nekuomerwa kwakanyanya uye kupfeka kupokana. Mune ino kesi, yakakwira-frequency furcching, makemikari carburization, nitriding, carbonitrid Iko ukobvu hwesimba rinoomesesa atowanzoita pakati pemamirimita mashoma nemamirimita mashoma. Zvekushandisa nehuremu hwekuomarara hutsinye, hrc zviyero zvinogona kushandiswa kuyedza kuomesa kwavo. Yepakati pepasi uko kumusoro kuomesa nzizi, HRR kana HRA zviyero zvinogona kushandiswa. Zvekutetepa nzvimbo dzakaomeswa dzakaomarara, kubva kune mhouwell hardness scales hr15n, hr30n, uye hr45n inofanira kushandiswa. Zvematete akaomarara akaomeswa, micro vickers hardness tester kana ultrasonic hardiner inofanirwa kushandiswa.
3. Simbi yakashamiswa, yakajairika simbi, nyoro nyoro
Zvigadzirwa zvakawanda zvesimbi zvinogadzirwa mune yakashongedzwa kana yakajairika mamiriro, uye imwe inotonhora yakamonera mahwendefa akakomberedzwawo zvinoenderana nemadhigirii akasiyana. Iko kuomesa kwekuomesa kwesimbi dzakasiyana-siyana dzakashata dzinowanzo kushandisa HRB zviyero, uye dzimwe nguva HRF zviyero zvinoshandiswawo kune zvakare kune zvakapetwa uye zvakaonda mahwendefa. Zvemapuranga akaonda, Rockwell Hardness Testers HR15T, HR30T, uye HR45T zviyero zvinofanirwa kushandiswa.
4. Stainless simbi
STOPLess STEEL ZVINHU ZVINOGONESWA MUZVINHU ZVINOGONESESWA SEZVINOGONESESWA, KUPEDZESA, Kupararira, uye mhinduro yakasimba. Mitemo yenyika inotsanangura iyo inoenderana yepamusoro uye yakaderera yakaoma tsika, uye kuomesa kwekuedza kunowanzoita rockwell hardness tester hrc kana hrb zviyero. Chiyero cheHRB chinozoshandiswa kune Austenitic uye ferritic simbi isina kuomarara, uye hrn chiyero cheRockwell tever
5. Yakagadzirirwa simbi
Iyo brinell yakaoma kuomesa bvunzo inowanzoshandiswa simbi yakagadzirirwa, nekuti iyo microcture yesimbi yakagadzirirwa haina yunifomu yakakwana, uye iyo brinell kuomarara kwekutarisa kwakakura. Naizvozvo, bvunzo yeBrinell inogona kuratidza mhedzisiro yezvigadzirwa uye zvivakwa zvezvikamu zvese zvezvinyorwa.
6. Kanda iron
Kanda zvinhu zvesimbi zvinowanzoonekwa neisina kuenzana mamiriro uye zviyero zvine mwero, saka brinell hardness kuomesa bvunzo kunowanzoitwa. Iyo Dombowell Hardness Tester inogona kushandiswa kuomesa kwekuomesa kwevamwe kwakakanda mwero webasa. Iko hakuna nzvimbo yakakwana pane chikamu chidiki chezvakanaka zvekukanda zviyo zveBrinell kuomarara kuomesa, nekuti hrecal scaly steel mabhora kupfuura 1.588mm diameter mabhora.
Zvakaoma kuvhenekera zvinongedzo zvesimbi zvinowanzo shandisa hardness hardness tester hrc. Kana zvinyorwa zvacho zvichinge zvisina kuenzana, dzakawanda data inogona kuyerwa uye huwandu hwepakati hwakatorwa.
7. Sitreed carbide (yakaoma alloy)
Kuedzwa kwezviitiko zvakaoma zvezvigadzirwa zvinowanzoita chete zvinoshandisa iyo Dombowell Hardness Tester HRA Salkes.
