Maererano nokukanda rusvingo ukobvu uye zvinhu giredhi kusarudza makemikari anoumba

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 pamwe chete zvinotarisisa chimiro chemetallographic chechigadzirwa.

Zvese zviri zviviri ferrite cast iron uye pearlitic cast iron inoda Si (kuchinja Zvirimo zveSi zvinoreva kushandura CE) uye MN.

Castings inogona kuverengerwa seimwe yeaviri substrates zvichienderana nekuumbwa kwavo kwemakemikari, zvinoreva kuti pane zvinokwana zvina zvinongedzo kuti zvizadzise inodiwa kemikari mukugadzirwa kwemagiredhi akasiyana ezvikamu zvakatetepa-nemadziro uye makobvu-ane madziro.

Cherechedza:

1. Huremu hwezvinhu zvakasiyana-siyana hunogona kuverengerwa nekuwanza huremu hwesimbi yakanyungudutswa inogadzirwa ne% % yezvigadzirwa zvakawedzerwa.

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 kuomarara kuzadzisa zvakafanotemerwa zvinodiwa isarudzo iri nani.

3. Silicon carbide inogona kuwedzerwa kuderedza yakanyungudutswa simbi oxidation uye kudzivirira choto lining (general adding amount is 0.2%), inogona kutamba chikamu chekuwedzera kweC uye silicon effect.

4. Muyero wekutora unonyanya kuC uye Si.
