Marata esimbi asingapfeki:
(1) NM360 (kupfeka-resistant 360)
Kupa zita: N ndiko kuramba (nai) M ibhii rekutanga repinyin remavara maviri ekuChina ekukuya (mo), uye 360 inomiririra avhareji yeBrinell kuoma kwemahwendefa aya esimbi.
Kurapa kwekupisa: kupisa kwakanyanya, kudzima + kupisa (kudzima uye kudzikisira)
Kushandisa: NM360 kupfeka-resistant simbi pepa rinoshandiswa zvakanyanya mumashini emigodhi, marasha emigodhi michina, zvakatipoteredza.
Iyo zvakare inowanzoshandiswa seyepamusoro-yakasimba simbi yekugadzira ine goho simba ≥ 700MPa.Iyo inonyanya kupa dziviriro yezviitiko kana zvikamu zvinoda kusapfeka, kuitira kuti michina iite hupenyu hwakareba, kuderedza kuchengetedza kunokonzerwa nekugadzirisa, uye nenzira imwecheteyo kudzikisa capital investment.
Performance: Goho rinopfuura mazana masere, uye simba rekusimba rinopfuura 1000.
(2) NM400
NM400 ndeye yakakwirira-simba kupfeka-inodzivirira simbi mahwendefa.NM400 ine simba rakawanda remuchina;midziyo yayo yemagetsi ndeye 3 kusvika ku5 nguva yeakajairika akaderera-alloy simbi mapepa;inogona kuvandudza zvakanyanya kupfekedzwa kwekupokana kwezvikamu zvine chekuita nemakanika;nokudaro kuvandudza hupenyu hwebasa hwemakina uye kuderedza mari yekugadzira.Kuoma kwepamusoro kwechigadzirwa ichi kunowanzosvika 360 ~ 450HB.Inoshanda marata esimbi ekugadzira uye kugadzira ezvisingapfekeke uye zvikamu zvisina njodzi zvemigodhi nemichina yekuvaka yakasiyana.
NM400 kupfeka-resistant simbi pepa rinoshandiswa zvakanyanya mumichina yekuvaka, muchina wemigodhi, muchina wekuchera marasha, michina yekudzivirira kwezvakatipoteredza, michina yesimbi uye zvimwe zvikamu zvechigadzirwa.Excavator, loader, bulldozer bucket plate, edge plate, side edge plate, blade.Crusher liners, mashizha.
(3) Mn13 (yakajairwa yakakwira manganese simbi)
Mn13 isimbi yakakwira manganese kupfeka-resistant simbi (HIGH MANGANESE STELL SCRAP), iri sarudzo yakanakisa pakati pezvinhu zvinopfekwa senge kusimba kwakasimba uye kupfeka kwakanyanya-kumanikidza zvinhu.
Kune maviri makuru maitiro eyakakwira manganese simbi: imwe ndeyekuti iyo yakakura kukanganisa kwekunze, ndiko kukwirisa kwekupfeka kwekupokana kweyayo yepamusoro denga.Kana ikakanganiswa, kuoma kwayo kwepamusoro kuchakurumidza kuwedzera kubva paHB200 kusvika pamusoro peHB700, nekudaro ichigadzira yakanyanya kupfeka-inodzivirira pamusoro pedhiri.Iyo austenite muchikamu chemukati chendiro yesimbi ichiri kuchengetedza kunaka kwesimba kusimba;chechipiri ndechokuti nekupfeka zvishoma nezvishoma kwepamusoro-soro yakaomeswa, mitsva yekushanda-yakaoma icharamba ichiumba.
Mn13 yakakungurutswa ndiro yesimbi ine yakanakisa kupfeka kuramba kune yakasimba kukanganisa kupfeka uye yakanyanya kushushikana kupfeka, haizotyoke panguva yekushandiswa, uye ine nyore machining zvimiro sekucheka, welding, uye kukotama.
Nechinyakare yaishandiswa yakakwirira chromium cast iron ine yakanaka kupfeka kuramba chete yekufambisa kupfeka.Mn13 yakakungurutswa ndiro yesimbi inogona kunyatso kudzikisa mutengo wekushandisa wekupfeka zvikamu zvemidziyo, kuchengetedza mari yekuchengetedza michina, uye kugadzirisa kukwikwidza kwezvakapera zvigadzirwa.
Nekudaro, iyo yekupfeka kuramba kwesimbi yakakwira manganese inoratidza hukuru hwayo chete pasi pemamiriro akakwana kuita basa rakaoma, uye irombo mune dzimwe nyaya.
Iyo yakajairika Mn17 inomira-inodzivirira yakakwirira-manganese simbi ndeyekuwedzera huwandu hwemanganese pahwaro hweMn13 simbi, iyo inovandudza kugadzikana kweaustenite uye inodzivirira kunaya kwecarbides, nekudaro ichivandudza simba uye plastiki yesimbi nekuvandudza basa. kuomesa kugona kwesimbi.uye kuramba abrasion.Semuenzaniso, hupenyu hwebasa reZGMn18 maforogo enjanji anoshandiswa kuchamhembe ndeye 20% ~ 25% yakakwirira kupfuura yeZGMn13.
Magiredhi uye chiyero chekushandiswa kwesimbi yakakwira manganese inowanzoshandiswa kuChina ndeiyi: ZGMn13-1 (C 1.10%～1.50%) inoshandiswa kune yakaderera-impact parts, ZGMn13-2 (C1.00% ~1.40%) inoshandiswa zvikamu zvakajairika, ZGMn13- 3 (C0.90% ~ 1.30%) inoshandiswa kune zvikamu zvakaoma, uye ZGMn13-4 (C0.90% ~ 1.20%) inoshandiswa kune zvikamu zvepamusoro.Iyo manganese yemukati yemagiredhi mana epamusoro esimbi ndeye 11.0% kusvika 14.0%.
Nekugadzirisa nekugadzirisa, austenite-based manganese-nickel electrodes (rudzi rweD256 kana D266) inofanira kusarudzwa, neine yakareba uye yakaonda tsanangudzo, φ3.2mm × 350mm, uye kunze kwekuputira kune alkaline.Iyo nzira yekushanda inotora DC reverse yekubatanidza, diki ikozvino, isina simba arc, diki welding bead uye akawanda welding layer, uye inogara ichichengetedza yakaderera tembiricha uye yakaderera kupisa.Rova paunenge welding kubvisa kushushikana.Kukandira kwakakosha kunofanirwa kuonekwa kukanganisa.Flash welding (Swiss GAAS80/700 flash welding muchina) kana MAG welding (yakadai seNissan YD-S-500) inogona kushandiswa kune yakakosha welding, iyo inogona kunyatso simbisa iyo welding seam mechanic properties.
Appendikisi 1: Pfungwa yekuoma
Kuomarara indekisi yekuita kuyera kupfava nekuoma kwezvinhu.Kune nzira dzakawanda dzekuedza kuomarara, misimboti haina kufanana, uye kuyerwa kuomarara kukosha uye zvirevo hazvina kunyatsofanana.Inonyanya kuzivikanwa ndeye static load indentation method hardness test, zvinoti Brinell hardness (HB), Rockwell hardness (HRA, HRB, HRC), Vickers hardness (HV), rabha plastiki Shore hardness (HA, HD) uye humwe hurema Kukosha kwayo kunoratidza kukwanisa kwepamusoro pezvinhu zvekudzivisa kupindira kwechinhu chakaoma.Kuomarara hakusi kuwanda kwemuviri kwakapusa, asi indekisi yekushanda yakazara inoratidza kusimba, purasitiki, simba uye kuoma kwezvinhu.
Kuoma kwesimbi: Zita rekodhi rekuoma kwesimbi ndiH. Maererano nemaitiro akasiyana-siyana ekuedzwa kwekuoma, pane kunyanya kunotevera mazwi.
●Matauriro akajairika anosanganisira Brinell (HB), Rockwell (HRC), Vickers (HV), Leeb (HL) kuoma, nezvimwewo, pakati payo HB neHRC zvinowanzoshandiswa.
● HB ine zvakawanda zvakasiyana-siyana zvekushandisa, uye inowanzoshandiswa kana zvinhu zvinyoro, zvakadai sesimbi isina-ferrous, simbi isati yatanga kupisa kana mushure mekuvhara.HRC inokodzera zvinhu zvine kuomarara kwepamusoro, sekuomarara kwekupisa, nezvimwe.
Musiyano uripo pakati pezviviri ndewekuti probes yevakuomarara testers akasiyana.Maprobe eBrinell hardness tester mabhora esimbi, ukuwo maprobe eRockwell hardness tester ari madhaimani.Mune mamwe mamiriro ezvinhu, HB neHRC zvinogona kuchinjana nekutarisa kumusoro kwetafura.Yayo yekuverenga formula yepfungwa inogona kunyorwa se: 1HRC≈1/10HB.
●HV-yakakodzera kuongororwa kwemicroscopic.Vickers hardness (HV) inotsikirirwa pamusoro pechinhu chine mutoro usingasviki 120kg uye diamond square cone indenter ine vertex angle ye 136 °, uye nzvimbo yepamusoro yegomba rekupinza rezvinhu rakakamurwa nemutoro. kukosha, inova iyo Vickers kuomarara kukosha (HV).Rockwell kuomarara (HR-) inotemerwa nekudzika kweiyo indentation epurasitiki deformation kuona iyo kuoma kukosha index.Zviri nyore kushanda, nekukurumidza uye intuitive, uye yakakodzera kugadzirwa kwehuwandu.
