Yepamusoro{{0}chromium cast iron ianti-kupfeka zvinhu uye inoshanda zvakanakisa, uye maumbirwo ayo emakemikari anonyanya kusanganisira kabhoni, chromium, manganese, sililicon nezvimwe zvinhu. Iyo kabhoni yemukati yakakwira, inogona kusvika kupfuura 3.0%, iyo chromium yemukati inowanzoita 26%, silicon uye manganese zviri pakati nepakati, zvinhu izvi zvinoshanda pamwechete kuvandudza kusimba, kuoma uye kupisa kwakanyanya kwechinhu. Pamusoro pezvo, yakakwira chromium cast iron inewo huwandu hwakakodzera hwearoyi zvinhu senge nickel, molybdenum nemhangura, pakati peiyo chromium ndiyo chinhu chikuru, zviri mukati zviri pakati pe10% -30%, kazhinji 15% -22%. Ichi chinyorwa chinozivikanwa nekusapfeka kwepamusoro, kusimba kwepamusoro, kusimba kwepamusoro, uye kunaka kwepamusoro tembiricha uye kusaita ngura, uye inoshandiswa zvakanyanya munzvimbo dzakasiyana dzekusapfeka.
Yakakwira chromium yakakanda simbi inopfeka pombi yekudzivirira chinhu chine yakanakisa kupfeka kuramba uye corrosion kuramba, iyo inoshandiswa zvakanyanya muminda yakawanda.
1. High-chrome cast iron wear-inodzivirira pombi inoshandiswa zvakanyanya muindastiri yezvicherwa, inonyanya kushandiswa mukufambisa michina yemigodhi. Nekuda kwekunyanya kusakara kwezvinhu mumigodhi, kushandiswa kwe-zvinhu zvisingachinjiki kuvandudza hupenyu hwemichina. Yakakwira chromium yakakanda simbi inopfeka inopikisa pombi ine yakakwira kupfeka kuramba, inogona kunyatso ramba kupfeka kwezvinhu, kuitira kuvandudza hupenyu hwesevhisi hwemuchina.
2. Iyo yakakwirira-chromium cast iron wear-inodzivirira pombi inoshandiswawo zvakanyanya muindasitiri yemagetsi. Mumarasha{{4}magetsi emagetsi,{{5}chromium cast iron wear yakakwira-pombi dzisingadziviriki dzinoshandiswa zvakanyanya mukufambisa marasha bhoiler nemasisitimu ekukuya marasha. Nekuda kwekunyanya kusakara kwezvinhu mukutakura marasha uye masisitimu ekukuya marasha-magetsi anobatidzwa, kupfeka-zvisingachinji zvinodikanwa kuti zvigadzirise hupenyu hwemidziyo. Yakakwira chromium cast iron kupfeka kupokana pombi ine yakakwira kupfeka kuramba, inogona kunyatso ramba kupfeka kwezvinhu, nekudaro inovandudza hupenyu hwesevhisi yemidziyo.
3. Indasitiri yezvivakwa zvekuvaka yakakwira chromium cast iron kupfeka-pombi isingachinjiki muindasitiri yezvivakwa zvinoshandiswawo zvakanyanya muindasitiri yezvivakwa. Muchirimwa chesimende, chromium cast iron yakakwira kupfeka-pombi isingachinjiki inoshandiswa zvakanyanya muchigayo chesimende uye feni huru nemimwe michina. Nekuda kweiyo yakaipa kwazvo mamiriro ekushanda emidziyo iyi, kupfeka kwezvinhu uye kusvibiswa kwemhepo kunokonzeresa kukuvadzwa kukuru kumidziyo. Yakakwira chromium yakakanda simbi inopfeka inopikisa pombi ine yakakwira kupfeka kuramba uye kusagadzikana kwekuora, inogona kunyatso ramba kupfeka kwezvinhu uye ngura yemhepo, nekudaro inovandudza hupenyu hwebasa remidziyo.
4. High-chrome cast iron wear-pombi isingachinjiki inoshandiswawo zvakanyanya muindasitiri yemakemikari. Mumiti yemakemikari,{4}chromium cast iron wear yakakwira-pombi dzinodzivirirwa dzinoshandiswa zvakanyanya mumareactor akasiyana, pombi nemavharuvhu. Nekuda kwemamiriro ekushanda asina kunaka emidziyo iyi, kukora kweasidhi, alkali, munyu nemamwe makemikari uye kusakara kwezvinhu zvinokonzeresa kukanganisa kukuru kumidziyo. Yakakwira chromium cast iron kupfeka kuramba pombi ine yakakwira kupfeka kuramba uye kusagadzikana kwekuora, inogona kunyatso ramba kupfeka kwezvinhu uye kemikari corrosion, kuitira kuvandudza hupenyu hwebasa remidziyo.
5. Pamusoro peminda iri pamusoro, kupfeka kwesimbi yechrome yakakwirira-inodzivirira kupfekwa inoshandiswawo zvakanyanya mumunda wekudiridza. Mapaipi mumadiridziro ekurima anowanzosakara nekukuvadzwa nekuda kwezvinhu zvakaita sevhu nemidzi yezvirimwa. High chrome cast iron wear-inodzivirira pombi ine kusakara kwakanyanya uye kusaita ngura, izvo zvinokwanisa kudzivirira kukuvadzwa kwezvinhu izvi uye kuve nechokwadi chekushanda kwakajairika kwemadiridziro. Panguva imwecheteyo, nekuda kwekugara kwayo kwakasimba, inogonawo kuderedza kuwanda kwekugadziriswa kwepombi uye kuderedza mari yekugadzirisa. Pamusoro peminda iri pamusoro, yakakwira chrome cast iron inodzivirira pombi inoshandiswawo mune mamwe akawanda minda. Semuenzaniso, muindasitiri yepetroleum, yakakwira chrome cast iron inopfeka machubhu anoshandiswa kutakura mafuta asina kuchena uye zvigadzirwa zvakanatswa; muindasitiri yekuvaka ngarava, yakakwira chrome yakakanda simbi inopfeka isingachinji machubhu anoshandiswa mungarava mafuta masisitimu uye hydraulic masisitimu; muzvifambiso zvechitima, machubhu akakwira chrome cast iron wear resistant machubhu anoshandiswa mumabhureki echitima, zvichingodaro. Kushandiswa mundima idzi kwaratidza kushanda kwakakura uye kushanda kwakanaka kwemachubhu ehigh chromium cast iron wear{9}}anodzivirira machubhu.
