Nzvimbo yekurima yemichina yekurima/yekutsvaira/yekutsvaira foshoro/yekutsvaira yakaita semuseve

Tsananguro pfupi:

Foshoro iyi ine mapapiro maviri yakaita semuseve inoshandiswa pakurima michina yekurima,

yakagadzirirwa kuchengetedza zvirimwa mumunda. Muviri mukuru wakagadzirwa nesimba guru

Simbi isingaparare senge simbi ye65Mn, yakaomeswa nekupisa uye kudzimwa, ine kuomarara kwakanyanya,

kuramba kwakasimba kwekupfeka, kuramba kukanganiswa uye kuramba kukotama, izvo zvinogona kuchinjika kumunda wakasimba

mashandiro. Pamusoro payo panoiswa pendi yebhuruu inodzivirira ngura kuti iwedzere hupenyu hwebasa.

Ruzivo rweChigadzirwa

Matagi eChigadzirwa

Zvikamu zvekubatsira zvemichina yekurima, zvakaita semagejo nemafoshoro, zvakagadzirwa nesimbi yakasimba uye isingaparare. Mupendero wepamusoro wakagadziriswa kupisa kwakakosha, zvichiita kuti ive yakapinza uye inogara kwenguva refu, isina simba rakawanda rekupinda muvhu. Yakakodzera kuchera zvakadzika pasi pemamiriro akasiyana-siyana evhu, zvichivandudza zvakanyanya kushanda kwekucheka nekutenderera kwevhu. Dhizaini yayo yekuisa maburi inoenderana nemamodheru ejecha akajairika uye iri nyore kutsiva. Inodzivirira kukanganiswa nekukotama, inogona kuwedzera hupenyu hwese hwezvikamu zvekurima uye isarudzo yakanaka yekushanda kwekurima kwakanaka.

Chigadzirwa ichi chakagadzirwa nezvinhu zviviri zvemhando yepamusoro, simbi yemanganese ye65Mn uye simbi yeboron ye30MnB, zvinoumbwa nekugadzirwa kweintegral integral inodziya zvakanyanya. Chimiro chechinhu chacho chakakora uye hachina zvikanganiso zvakaita semaburi nemakomba ejecha. Nekushandisa nzira yekurapa kupisa ye isothermal quenching, kuoma kwemuromo wefoshoro kunosvika 48-52HRC, uye kuoma kwe matrix kunoramba kuri pamusoro pe35-40J/cm², zvichizadzisa mamiriro akanaka ekushanda kwe "kuoma kwekunze uye kuoma kwemukati". Nzvimbo iyi yakagadziridzwa yakaitwa nekurapwa kwakasimba kwenzvimbo, nekuoma kwe55HRC uye yakawedzera zvakanyanya kuramba kwekusakara.

Foshoro yegejo inoshandisa chimiro chakakombama chakakombama, uye kona yekuisa inoverengwa nemazvo (inogadziriswa kubva pa22 ° kusvika 28 °), zvichideredza zvinobudirira kuramba kudhonzwa neanenge 15% -20%. Musoro wefoshoro nemadziro efoshoro zvakabatana nenzira inofambira mberi kubvisa nzvimbo dzekushushikana. Yakashongedzerwa nemaburi maviri anodzivirira kusunungura seyakajairwa, anoshandiswa pamwe chete nenzungu dzinozvivharira kuti ive nechokwadi chekuti inoshanda kwenguva refu pasina kusunungura. Mamwe mamodheru anochengetedza nzvimbo dzefoshoro dzinotsiviwa, uye zvikamu zvepamberi chete ndizvo zvinofanirwa kutsiviwa mushure mekunge muromo wefoshoro wapera, zvichideredza mari yekugadzirisa.

Kusapfeka zvakanyanya: Nguva yekushanda kwayo yakareba ka2-3 kupfuura mafoshoro akajairwa ekukanda, uye inogona kushanda nguva dzose kwemaeka 800-1200 pasi pemamiriro ekunze akajairwa e loam.

Kusabatwa nenjodzi: Kana ukasangana nezvipingamupinyi zvakaita sematombo nemidzi yemiti, matrix yakasimba inogona kudzikamisa uye haiputsike nyore nyore

Kuzvirodza: Chimiro chakasarudzika che multilayer composite chinochengetedza banga rakapinza panguva yekusakara uye kubvaruka

Kudzivirira kupatsanurwa kwevhu: Pamusoro paro panokweshwa kuti pawedzere huwandu hwekupatsanurwa kwevhu ne30%, zvichiita kuti rikwanise kushandiswa muvhu rakaoma
