Simbi simbi

Iro simbi yakasviba iyo inokandwa nesimbi yakanyungudutswa uye yakamanikidzwa mushure mekutonhora.
Iyo iri flat, rectangular uye inogona kutemwa zvakananga kana kutemwa kubva kune yakafara simbi mitsetse.
Iyo simbi ndiro yakakamurwa zvichienderana neiyo gobvu, iyo simbi simbi iri pasi pe4 mm (iyo yakaonda ndeye 0.2 mm), iyo yepakati-mmms simbi, uye iyo yekuwedzera-gobvu blate ndeye 60-115 mm.
Zvimhe zvesimbi zvakakamurwa mukupisa-kutenderera uye kutonhora-kutenderera maererano nekufamba-famba.
Upamhi hwenzvimbo yakatetepa ndeye 500 ~ 1500 mm; Upamhi hweiyo gobvu pepa ndeye 600 ~ 3000 mm. Mashitsi anozivikanwa nerudzi rwesimbi, kusanganisira yakajairika simbi, simbi yepamusoro simbi, simbi yesimbi, inopisa simbi, Simbi Simbi uye Indasitiri Simbi Simbi Simbi Steel Steel. Enamel ndiro, bulletproof ndiro, etc. Maererano nepamhepo coating, pane bepa rakarongedzwa, tin-rakarongedzwa sheet, pepa rakarongedzwa, purasitiki.
Yakaderera alloy yakarongedzwa simbi
(zvakare inozivikanwa seyakajairika yakaderera Alloy Simbi, Hsla)
1. Chinangwa
Inonyanya kushandiswa mugadziri yemabhiriji, ngarava, mota, midziyo yakakwirira, midziyo yokumanikidza, mafuta uye gasi masheya, zvivakwa zvakakura, nezvimwe.
2. Performance zvinodiwa
(1) Simba Rakakwira: Kazhinji Simba rayo rakabiwa riri pamusoro pe300mpa.
. Zvezvikamu zvikuru zvezvinyorwa zvakakura, zvakanyanya kupunzika kuomarara kunodiwawo.
.
(4) Yakadzika inotonhora-brittle transition tembiricha.
(5) Kupesana kwakanaka kwehutori.
3. Under hunhu

16mn ndiyo inonyanya kushandiswa uye yakawanda inobereka mhando yeiyo yakaderera-alloy yakakwira-simba simbi munyika yangu. Chimiro chekushandisa muHurumende chakasarudzika-pearlite, uye simba rayo ndere 20% kusvika ku30% yakakwira kabhoni kugadzirwa simbi ndeye 20% kusvika pamakumi maviri nemakumi matatu neshanu muzana.
15mnvn ndiyo inonyanya kushandiswa simbi mune yepakati-simba nzizi. Iyo ine simba rakanyanya, uye kuoma kwakanaka, nekuoma uye nekuomarara kwakaderera, uye kunoshandiswa zvakanyanya mukugadzirwa kwezvivakwa zvakakura senge mabhiriji, maburi, uye ngarava.
Mushure mekunge chikamu chesimba chinopfuura 500mpa, iyo ferrite uye zvigadziko zvemafuro zvakaoma kuita zvinodiwa, saka yakadzika kabhoni Boka ririmo rinokudziridzwa. Kuwedzera kwekuva 1, mn, b uye zvimwe zvinhu zvinobatsira kuti uwane mamiriro emhepo pasi pemhepo, kuti ishandiswe. , midziyo yakakwirira-yakakwirira, nezvimwe.
5. Hunhu hwekupisa kurapwa
Rudzi urwu rwesimbi runowanzoshandiswa mune inopisa-yakatenderera uye yemhepo-yakatonhorera nyika uye haidi kurapwa kwakakosha kupisa. Iyo micrantructure iri mukushandisa nyika inowanzo farira + sorbhi.
Alloy Carburized Simbi
1. Chinangwa
Iyo inonyanya kushandiswa mugadziri yekufambisa magiya mumotokari uye maturakiti, Camshafts, Piston Pins uye zvimwe zvidimbu zvemuchina pane zvemukati menyu injini. Zvikamu zvakadaro zvinotambura kubva mukupokana kwakasimba uye kupfeka panguva yebasa, uye panguva imwechete yeberekiti yakakura ichichinjana, kunyanya kukanganisa mitoro.
2. Performance zvinodiwa
.
. Kana kuomarara kweiyo musimboti hakuna kukwana, zviri nyore kuputsa pasi pechiitiko chekukanganisa mutoro kana kuyambuka; Kana simba risina kukwana, iyo brittle carbeld layer inoputswa nyore nyore uye yakatetepa.

.
4. Steel giredhi uye giredhi
20Cr yakaderera yakaoma Alloy Alloy Carbleed Simbi. Iyi mhando yesimbi ine yakaderera kuomarara uye yakaderera musimboti simba.
20CrMnTINDIMEDIum Hardenabilation Alloy Carburized Simbi. Rudzi urwu rwesimbi rune hardenability, yakaderera kuderera kwekunzwa, yakajeka yunifomu carblization transition layer, uye yakanaka michina uye tekinoroji uye tekinoroji.
18cr2ni4wa and 20cr2ni4a High Hardenability Alloy Alloy Carburized Simbi. Rudzi urwu rwesimbi rine zvimwe zvinhu zvakadai seiri acr uye ni, ine miganho yakakwirira, uye ine kuomarara kwakanaka uye kupisa-tembiricha kukanganisa kuomarara.
5. Kupisa kurapwa uye microcenture zvivakwa
Iyo yekupisa kurapa maitiro eAlloy Carbleed Simbi inowanzo bvisa kudzima mushure mekutakura, uye wobva wazungunuka pakudziya kwakadzika. Mushure mekurapa kwekushisa, chimiro chemusoro wepamhepo chakarukwa chibvumirano chezvemari + nehasha marensite + chiyero chidiki cheAustenite, uye kuomarara kuri 60hrc ~ 62hrc. Iyo core dhiza ine hukama nekusagadzikana kwesimbi uye kuwanda-chikamu chikamu chezvikamu. Kana akaomeswa zvizere, yakaderera-carbon akatsamwisa martensite ine kuomarara kwe40hrc kusvika 48hrc; Muzhinji, inonzi Trostite, akatsamwa, uye simbi simbi. Element muviri, kuomarara ndiko 25hc ~ 40hrc. Kuomarara kwemoyo kunowanzo kukwirira kupfuura 700kj / m2.
Alloy akadzima uye akatsamwa simbi
1. Chinangwa
Alloy yakabviswa uye yakachena simbi inoshandiswa zvakanyanya mukugadzira zvakasiyana-siyana zvakakosha zvikamu pamotokari, maturakiti emachina, shafts, inobatanidza tsvimbo, mabheti, nezvimwe.
2. Performance zvinodiwa
Vazhinji vevakadzoserwa uye vanotsamwa zvikamu zvinotakura zvinhu zvakasiyana siyana zvinoshanda, mamiriro ezvinhu ekushushikana akanyanya kuoma, uye akanyanya kuwirirana midziyo anodikanwa, ndiko kuti, simba rakanyanya uye rakashata uye rakaoma. Alloy yakabviswa uye yakatsamwa simbi inodawo kuomarara kwakanaka. Nekudaro, mamiriro ezvinhu ekunetseka ezvikamu zvakasiyana akasiyana, uye zvinodiwa nekuomerwa kwakasiyana.

. Kuwedzerwa kweMolybdenum hakugone kungosimudzira kuomarara, asi zvakare kudzivirira yechipiri mhando yehasha brittleness.
. Kuwedzera yakakodzera molybdenum kuenda ku chromium-nickel simbi haina kungowoma chete, asi zvakare inobvisa yechipiri mhando yehasha brittleness.
5. Kupisa kurapwa uye microcenture zvivakwa
Iyo yekupedzisira yekupisa kurapwa kweiyo alloy yakabviswa uye yakatsamwa simbi ndeyekudzima uye yakakwira tembiricha temperation (kudzima uye kupaza uye kutsamwa). Alloy yakadzurwa uye yakachena simbi ine high yakaoma, uye mafuta anowanzo shandiswa. Kana kuomarara kwakanyanyisa, kunogona kutove nemhepo-yakatonhorera, iyo inogona kuderedza kupisa kupisa kuremara.
Zvivakwa zvekupedzisira zveAlloy zvakadzimwa uye nekutsamwa simbi inoenderana nekushisa tembiricha. Kazhinji, kutsamwa pa500 ℃ -650 ℃ inoshandiswa. Nokusarudza tembiricha yekudziya, zvivakwa zvinodiwa zvinogona kuwanikwa. Kuti udzivirire mhando yechipiri yehasha brittleness, kukurumidza kutonhora (mvura inotonhorera kana yemafuta inotonhorera) mushure mekutsamwa inobatsira kuomesesa.
Iyo microdhi yeAlloy yakadzurwa uye yakatemwa simbi mushure mekurapa kwemaitiro ekupisa kwakadzikira shungu. Zvezvikamu zvinoda kupfeka zvinopfeka (senge magiya uye spindles), induction inopisa nzvimbo dzinodzora uye yakaderera-tuka inoitwa, uye chimiro chechiso chakashatiswa mrense. Kuomarara pamusoro pekusasvikira 55rc ~ 58hro.
Simba reukuru reAlloy rakadzurwa uye nekutsamwa simbi mushure mekudzora uye kutsamwa kwave kuita 800mpa, uye kuomarara ndiko kukwirira is 800kj / m2, uye kuomarara kweiyo core kunogona kusvika ku24hrc ~ 25hrc. Kana iyo chikamu-chikamu chikamu chakakura uye chisina kuomeswa, kuita kwakanyatso kuderedzwa.
