Tsanangudzo
Kuti ugadzire zvigadzirwa zvemhando yepamusoro pamutengo wakaderera nehunyanzvi hwepamusoro uye kuvimbika, unofanirwa kusarudza zvipfeko zvakagadziridzwa kune yako yekupwanya application. Zvinhu zvikuru zvekufunga nezvazvo sezvinotevera:
1. Mhando yematombo kana zvicherwa zvekupwanywa.
2. Material particle size, hunyoro hwemukati uye Mohs kuoma giredhi.
3. Zvinhu uye hupenyu hwemabheti ekurova akamboshandiswa.
Kazhinji, kupfeka kuramba (kana kuomarara) kwesimbi-yakaiswa simbi inodzivirira zvinhu zvinozodzikisira kupikisa kwayo (kana kuoma). Iyo nzira yekumisikidza ivhu musimbi matrix zvinhu inogona kuwedzera zvakanyanya kupfeka kwayo kuramba pasina kukanganisa kukanganisa kwayo.
High Manganese Steel
Yakakwira manganese simbi ndeye isingapfeki zvinhu zvine nhoroondo refu uye yakashandiswa zvakanyanya mukukanganisa macrusher. Yakakwirira manganese simbi ine yakatanhamara kukanganisa kupikisa. Iko kupfeka kupikisa kunowanzoenderana nekumanikidzwa uye kukanganisa pamusoro payo. Kana kukanganiswa kukuru kwakaiswa, iyo austenite chimiro chiri pamusoro chinogona kuomeswa kusvika HRC50 kana kupfuura.
Yakakwira manganese simbi simbi sando dzinowanzo kurudzirwa kupwanya kwekutanga nezvinhu zvehukuru hwekudya particle size uye kuomarara kwakaderera.

Microstructure yepamusoro manganese simbi
Martensitic Steel
Martensite chimiro chinoumbwa nekukurumidza kutonhora kweyakazara yakazara kabhoni simbi. Maatomu ecarbon anogona kupararira kunze kwemartensite chete mukukurumidza kutonhora mushure mekupisa. Martensitic simbi ine kuomarara kwepamusoro pane yakakwirira-manganese simbi, asi kupikisa kwayo kunodzikiswa. Kuoma kwesimbi yemartensitic iri pakati peHRC46-56. Zvichienderana neaya zvivakwa, martensitic simbi blow bar inowanzo kukurudzirwa kupwanya maapplication uko kune yakaderera maitiro asi yakakwirira kupfeka kuramba kunodiwa.

High Chromium White Iron
Mune yakakwira chromium chena iron, kabhoni inosanganiswa nechromium muchimiro chechromium carbide. Yakakwira chromium chena iron ine yakatanhamara kupfeka kuramba. Mushure mekurapwa kwekupisa, kuomarara kwayo kunogona kusvika 60-64HRC, asi kupikisa kwayo kunodzikiswa. Kuenzaniswa nesimbi yakakwira manganese uye martensitic simbi, yakakwira chromium cast iron ine yakanyanya kupfeka kuramba, asi kupikisa kwayo ndiko kwakadzikira.

Microstructure yeHigh Chromium White Iron
Ceramic-Metal Composite Material (CMC)
CMC chinhu chinopfekwa chinosanganisa kusimba kwakanaka kwezvinhu zvesimbi (martensitic simbi kana yakakwira-chromium cast iron) nekuomarara kwakanyanya kweindasitiri ceramics. Ceramic particles yehukuru chaihwo inobatwa zvakanyanya kuti iite porous body of ceramic particles. Simbi yakanyungudutswa inopinda zvizere mukati memukati meiyo ceramic chimiro panguva yekukanda uye inosanganisa zvakanaka nehari.
Iyi dhizaini inogona kunyatso kuvandudza maitiro ekurwisa-kupfeka kwechiso chekushanda; panguva imwecheteyo, iyo huru yebhari yekurova kana nyundo ichiri kugadzirwa nesimbi kuti ive nechokwadi chekushanda kwayo kwakachengeteka, kunyatsogadzirisa kupokana pakati pekupfeka kuramba uye kukanganisa kupikisa, uye inogona kuchinjirwa kune akasiyana ekushanda mamiriro. Inovhura munda mutsva wekusarudzwa kwezvipfeko zvepamusoro-soro kune vazhinji vevashandisi, uye kugadzira hupfumi huri nani.
a.Martensitic Steel + Ceramic
Kuenzaniswa neyakajairwa martensitic blow bar, iyo martensitic ceramic blow sando ine kuomarara kwepamusoro pane yakapfekwa pamusoro, asi kupikisa kwesando yekurova hakuzodzike. Mumamiriro ekushanda, iyo martensitic ceramic blow bar inogona kuva yakanaka kutsiva application uye kazhinji inogona kuwana kanokwana ka2 kana kureba hupenyu hwesevhisi.
b.High Chromium White Iron +Ceramic
Kunyangwe yakajairwa yakakwira-chromium iron blow bar yatove neyakanyanya kupfeka kuramba, kana kupwanya zvinhu zvine kuomarara kwakanyanya, senge granite, mamwe mabhawa asingapfekeri anowanzo shandiswa kurebesa hupenyu hwavo hwekushanda. Muchiitiko ichi, high-chromium cast iron ine yakaiswa ceramic blow bar ndiyo mhinduro iri nani. Nekuda kwekumisikidzwa kweceramics, kuomarara kwekupfeka kwesando yekurova kunowedzera kuwedzera, uye kusagadzika kwayo kunovandudzwa zvakanyanya, kazhinji kaviri kana hupenyu hurefu hwesevhisi pane yakajairika high chromium chena iron.
Zvakanakira zveCeramic-Metal Composite Material (CMC)
(1) Yakaoma asi isina brittle, yakasimba uye isingapfeki, kuwana chiyero cheviri chekusapfeka uye kusimba kwepamusoro;
(2) Kuomarara kweceramic ndeye 2100HV, uye kusamira kwekupfeka kunogona kusvika 3 kusvika ku4 nguva yeakajairika alloy zvinhu;
(3) Yakasarudzika chirongwa dhizaini, inonzwisisika kupfeka mutsara;
(4) Hupenyu hurefu hwebasa uye hupfumi hwepamusoro.
