Kuti isangane nezvinodiwa nemutengi, Shijiazhuang dong huan inogadzika iron castings co., Ltd yakagadziridzwa masimbi matsva anogadzika.Kune kemikari yezvakagadzirwa zvinhu tine muchidimbu.
Iyo C, Si, CE uye Mg kukosha kwekukanda kunofanirwa kusangana nehukuru hwekukanda.Saizi yechikamu chekukanda inosarudza mwero wekutonhora wekukanda, ukuwo kemikari uye mwero wekutonhodza zvakabatana zvinotarisisa chimiro chemetallographic chechigadzirwa.
Ose ari maviri simbi yakakandwa simbi uye pearlitic simbi inoda Si (kushandura Zviri mukati meSi zvinoreva kushandura CE) uye MN.
Castings inogona kuverengerwa seimwe yeaviri substrates zvichienderana nekuumbwa kwavo kwemakemikari, zvinoreva kuti kune zvingangove zvina zvinongedzo kuti zvizadzise inodiwa kuumbwa kwekemikari mukugadzirwa kwemagiredhi akasiyana ezvikamu zvakatetepa-ane madziro uye makobvu-ane madziro.
Cherechedza:
1. Huremu hwezvinhu zvakasiyana-siyana hunogona kuverengerwa nekuwanza huremu hwesimbi yakanyungudutswa inogadzirwa ne% % yezvigadzirwa zvinowedzerwa.
2. Zvinyorwa zveMN zvakagadzirirwa nemaune panzvimbo yakaderera, nokuti mu ferrite nodular iron, kunyange kana zvinyorwa zvakaderera, zvinogona kukurudzira kugadzirwa kwepearlite, mu pearlite, yakakwirira MN zvinyorwa zviri nyore kukonzera kuparadzaniswa kweMN mu. pearlite, kushandisa Cu kuita kuoma kuzadzisa zvakafanotemerwa zvinodiwa isarudzo iri nani.
3. Silicon carbide inogona kuwedzerwa kuderedza yakanyungudutswa iron oxidation uye kudzivirira choto lining (general adding amount is 0.2%), inogona kutamba chikamu chekuwedzera kweC uye silicon effect.
4. The absorption rate inonyanya kuC uye Si.
