Pakati pezvakasiyana zvakasiyana-siyana zvekukanda alloys, kupfeka-resistant cast simbi isimbi yakashandiswa zvakanyanya. Kupfeka-resistant simbi yakakandwa inonyanya kunatsiridza kupfeka kuramba kwesimbi castingsnekuwedzera zvakasiyana zvemukati zvealloying zvinhu, senge manganese, chromium, kabhoni, nezvimwe, kune alloy. Panguva imwecheteyo, kupikisa kupfeka kwesimbi-inodzivirira simbi castings kunoenderanawo nenzira yekupisa yekurapa inoshandiswa neiyofoundryuye chimiro chekuumbwa.
Zvinoenderana neakasiyana maitiro ekupfeka, kupfeka kwesimbi castings kunogona kukamurwa kuita abrasive kupfeka, anonamira kupfeka, kuneta kupfeka, corrosion kupfeka uye kusagadzikana kupfeka. Kupfeka-resistant simbi castings inonyanya kushandiswa mukatiminda yemaindasitirinemamiriro ekushanda akaoma uye yakakwira mechanic kuita zvinodiwa, senge migodhi, simbi,kuvaka, simba, petrochemical, kuchengetedza mvura,kurimauye maindasitiri ezvekufambisa. Pfeka-resistant simbi castings anonyanya kushandiswa mumamiriro eabrasion ane humwe hunhu hunorema, senge midziyo yekukuya, yekuchera, macrusher, matirakita, nezvimwe.
Muindasitiri yezvivakwa, mhando dzinowanzo shandiswa dzesimbi dzakakandwa dzinopfekwa dzinosanganisira simbi isingapfeki manganese, simbi isingapfeki chromium, simbi isingapfeki yakaderera-alloy cast uye simbi isingagadzirike kabhoni. PaRMC Foundry, simbi inodzivirira kupfeka inogona kukandwa nemaitiro akati wandei ekukanda kusanganisiragreen sand kukanda, resin yakavharwa jecha kukanda, kusabika mold kukanda, kuisa mari, kurasika furo uyevacuum casting.
1) Kupfeka-Kudzivirira Manganese Simbi
Zvinoenderana neyakasiyana manganese element yemukati, simbi inodzivirira manganese yekukandira inonyanya kukamurwa kuita yakaderera-manganese kupfeka-resistant simbi yakakandwa, yepakati manganese kupfeka-inodzivirira simbi yakakandwa uye yakakwira manganese kupfeka-inodzivirira simbi yakakandwa. Kupfeka-resistant manganese simbi ine kusimba kwakanyanya uye haisi nyore kuputsika panguva yekushandiswa. Panguva imwecheteyo, ine yakanakisa basa kuomesa zvivakwa, saka kupfeka-inodzivirira manganese simbi yakakodzera kune abrasive kupfeka mamiriro.
Anowanzo shandiswa magiredhi e-wear-resistant manganese simbi yekukanda ndeaya: M13 (Hadfield Steel), Mn5, Mn6, Mn7, Mn8, Mn17 ZG120Mn7Mo1, ZG120Mn13, ZG120Mn13Cr2, J9119, J911130, J91130, J911349, J9, etc.
2) Kupfeka-inodzivirira Chrome Simbi
Iyo inodzivirira kupfeka chromium simbi yekukandira inogadzirisa kuoma uye kupfeka kusagadzika kwesimbi yakakandwa nekuwedzera huwandu hwakakodzera hwechromium kune alloy simbi. Kuwedzera zviri mukati mechromium mukati mekabhoni simbi kunogona kuvandudza kuoma kwesimbi yakakandwa uye zvakare kunatsiridza kuoma kwesimbi yakakandwa. Kuwedzera hushoma hwe molybdenum kunogona kuwedzera kuomarara kwesimbi yakakandwa. Iyo nzira yekupisa yekupisa yekupfeka-inodzivirira chromium simbi inowanzo kupisa tembiricha yekudzima + yakaderera tembiricha kudzikama. Izvo zvinofanirwa kucherechedzwa kuti sezvo iyo kabhoni yemukati yekupfeka-inodzivirira chromium simbi inowedzera chero nguva, kuoma kwesimbi castings kuchawedzera, asi kuoma kwayo kuchaderera.
Anowanzo shandiswa mamakisi ekupfeka-resistant chromium simbi yekukanda ndeiyi: ZG30CrMo, ZG35CrMo, ZG40Cr, ZG40CrMo, ZG42CrMo, ZG50CrMo, nezvimwe.
3) Wear-Resistant Low-alloy Cast Steel
Yakaderera-alloy simbi inoreva simbi yealloy ine alloying element zviri pasi pe5%. Sezvo kuoma uye kuoma kwesimbi yakaderera-alloy cast inogona kugadziriswa mumhando yakakura, kupfeka-resistant low-alloy cast steel inoshandiswa zvakanyanya uye zvakanyanya. Pakusarudza nzira yekukanda simbi uye kupisa kupisa, zvinodikanwa kunyatso funga nezvesimba, simba rekuita uye kupfeka kuramba kweyepasi-alloy kupfeka-resistant simbi yekukandira kuti uwane yakanyanya kunaka mhedzisiro. Zvakajairika alloying zvinhu mu low-alloy kupfeka-resistant cast simbi zvinosanganisira molybdenum, chromium, manganese, nickel, uye silicon.
Anowanzo shandiswa mamakisi ekupfeka-resistant yakaderera-alloy simbi yekukanda ndeiyi: ZG30Mn2Si, ZG30Mn2SiCr, ZG30CrMnSiMo, ZG30CrNiMo, ZG40CrNiMo, nezvimwe.
4) Kupfeka-Kudzivirira Carbon Steel
Kupfeka kupikisa kwekabhoni simbi kunonyanya kuwanikwa nekuoma kwepamusoro kwesimbi castings. Kana iyo kabhoni yemukati yakakura kupfuura 0.35%, kuomeswa kwepasi kunowanzo shandiswa pamusoro pekukanda simbi. Kana iyo kabhoni yemukati iri pasi pe 0.35%, iyo kabhoni simbi castings inogona kuve carburized, nitrided kana carbonitrided kuvandudza kwayo kupfeka kuramba.
