Mukuita basa, jaw plate inowanzopfekwa, izvo zvinokanganisa kuita kwakajairika kwejaw crusher. Iri bepa rinoongorora yakaderera-kabhoni alloy simbi zvinhu zveshaya anopwanya, uye rinokurukura kuchinja mutemo shaya ndiro kuoma uye kupfeka kuramba, kuitira kuona quenching tembiricha kana shaya ndiro kupfeka kuramba kunosvika padanho rakanaka.
Kusarudzwa kwezvinhu zveshaya
1. Mukugadzira, ndiro inofambiswa yeshaya uye ndiro yakagadzika shaya inogadzirwa nesimbi isingachinjiki yakakwira manganese simbi, main bearing liner uye eccentric bearing liner inogadzirwa necast babbitt alloy, uye ndiro yeshaya inogadzirwa nesimbi yakakandwa kuti ivandudze. durability. Iyo jaw plate yeshay crusher inofanirwa kunge iri musevhisi pasi pekupfeka-inodzivirira, inodzivirira-inopikisa uye yakakwirira-kuoma mamiriro. Vagadziri vakasiyana vanoshandisa akasiyana shaya ndiro zvinhu, senge yakakwira manganese simbi, yepakati manganese simbi, alloy cast iron, yepakati kabhoni yakaderera alloy kupfeka-resistant simbi uye yakakwirira chromium cast iron.
2. Medium-carbon low-alloy wear-resistant simbi inowanikwa nekuwedzera zvinhu zvakasiyana-siyana zvealloy zvakadai seCr, Si, Mn, Mo, V pahwaro hwesimbi-carbon simbi, uye iyo yakazara alloy content isingasviki 5. %. Iri rudzi rwepakati-kabhoni yakaderera-alloy kupfeka-inodzivirira simbi inogona kunyatso gadzirisa akasiyana kabhoni yemukati uye alloy element yemukati, saka inogona kuenderana neyakasiyana nzira yekurapa kupisa kuti iwane akasiyana ma mechanic properties, saka yakwezva kutarisisa uye kushandisa. Mune bepa rino, kupikisa kwekupfeka kwepakati kabhoni yakaderera alloy ZG42Mn2Si1REB yakadzidzwa, uye mutemo wekuchinja wekuomarara uye kupfeka kuramba nekushisa kwekudzima kwakakurukurwa, uye nzira iri nani yekurapa kupisa yakawanikwa.
Tiye sarudzo yekupisa kurapwa maitiro
Zvinoenderana nehunhu hweZG42Mn2Si1REB simbi, iyo martensite chimiro chakawanikwa mushure mekudzima chine hurema hwepamusoro uye nani kupfeka kuramba. Matatu etembiricha mapoinzi e870 ℃, 900 ℃ uye 930 ℃ anosarudzwa kurapwa kwekupisa, uye tembiricha yekudziya inoiswa zvakafanana pa230 ℃. Nekuti izvo zvinhu hazvina Mo element, kuitira kuti ive nechokwadi chekuoma, 5% Nacl mhinduro inoshandiswa kutonhora.
Migumisiro uye kuongorora
1. Pesvedzero yekudzima tembiricha pane kuomarara uye kupfeka kuramba
Hukukutu hwemasamples akadzimwa patembiricha dzakasiyana akayerwa neHR-150A Rockwell huma mita, achiyera mapoinzi mashanu nguva yega yega obva atora avhareji kukosha. Zvakaonekwa kuti nekuwedzera kwekushisa kwekudzima, kuoma kwekudzima kwekutanga kwakawedzera uye kwakaderera. Kana tembiricha yekudzima iri 870 ℃, kuoma kuri HRC53. Kana tembiricha yekudzima yakwira kusvika pa900℃, kuoma kunokwirawo kusvika paHRC55. Zvinogona kuonekwa kuti kuoma kunowedzera nekuwedzera kwekushisa; Kana tembiricha ikaramba ichikwira kusvika pa930 ℃, kuomarara kunodzikira kusvika paHRC54, uye zvinogona kuwanikwa kuti kuoma kwacho kwakakwira kana kwakadzimwa pa900℃. Nokudaro, nekuwedzera kwekushisa, kupera kwehuremu kunoderera. Kana tembiricha ikaramba ichikwira kusvika 930 ℃, kupera uremu kunowedzera kusvika 3.5mg. Zvinogona kuonekwa kuti kana yakadzimwa pa900 ℃, kuoma kwayo kwakakwirira uye kupera kwehuremu kunoshaikwa. Iyo yepakati kabhoni yakaderera alloy kupfeka-inodzivirira simbi ZG42Mn2Si1REB ine yakanaka kupfeka kuramba, izvo zvinoratidza zvakare kuti maitiro panguva ino ndiyo chaiyo kupisa kupisa maitiro.
2. Kufananidzwa kwekupfeka kusagadzikana pakati pepakati carbon low alloy uye yakakwirira manganese simbi
Kuenzanisira kwepamusoro kupfeka kuramba kwepakati kabhoni alloy simbi ZG42Mn2Si1REB, chinhu ichi chinofananidzwa nepamusoro manganese simbi ZGMn13. Pakati pavo, ZG42Mn2Si1REB yakaedzwa maererano neakataurwa pamusoro petekinoroji mamiriro ekudzima pa900 ℃ uye kupisa pa230 ℃, uye yakakwira manganese simbi ZGMn13 yakabatwa nemvura yakaoma. Mhedzisiro yekuedza inoratidza kuti kusagadzika kweyekutanga ndeye 1.5 nguva yeyekupedzisira, izvo zvinoratidza kuti ndiro yeshaya yepakati kabhoni yakaderera alloy simbi yakanyatso shandisa mukana weiyo zvinhu uye ine yakanakisa kupfeka kusamira pasi pemamiriro akakodzera ekupisa kupisa.
Nezve mutengo wezvinhu, yakakwira manganese simbi ine inosvika 13% Mn, saka inoda kushandisa akawanda alloy zvinhu. Kuenzaniswa nesimbi yakakwira manganese, yepakati kabhoni yakaderera alloy simbi ZG42Mn2Si1REB ine chete 3% ~ 4% alloy zvinhu, uye haina yakakwirira-mutengo Cr uye Mo zvinhu, saka ine yakakwira mutengo wemakwikwi mukana. Mukuwedzera, tichifunga nezvekugadzirisa kupisa, iyo yepakati kabhoni yakaderera alloy simbi inodzimwa pa 900 ℃ uye yakanyoroveswa pa230 ℃, nepo mvura inoomesera kurapwa kwesimbi yakakwira manganese kazhinji inodarika 1000 ℃, saka tembiricha yekudzima yekare yakaderera, nguva yekupisa ipfupi, uye simba rekuchengetedza simba rinonyanya kushamisa. Iyo iri nani yekupisa kupisa yakashandiswa kune shaya ndiro yecrusher, iyo zviri pachena yakavandudza kusapfeka, uye kutsiva kutenderera kweplate reshaya yakawedzerwa kubva pa150d kusvika 225d, paine hupfumi huri pachena.
Kuburikidza netsvagiridzo yekupfeka kuramba kwejaw plate yepakati kabhoni yakaderera alloy simbi yejaya crusher, mhedzisiro inoratidza kuti kana yakadzimwa pa900 ℃, iyo microstructure mushure mekudzima ndeye martensite, panguva ino, kuoma kwakakwira, huremu hwekupfeka. kurasikirwa kwakaderera, uye kupikisa kupfeka kuri nani.
Shanvim semutengesi wepasirese wekupwanya akapfeka zvikamu, tinogadzira macone crusher akapfeka zvikamu zvemhando dzakasiyana dzecrusher. Tine makore anopfuura makumi maviri enhoroondo mumunda weCRUSHER WEAR PARTS. Kubva 2010, takatengesa kuAmerica, Europe, Africa nedzimwe nyika pasi rose.
