Kukanda kukanganisa kwesimbi inogoneka yakakandwa uye nzira yekudzivirira

Chirema chimwe: Haikwanise kudurura

Zvimiro: chimiro chekukanda hachina kukwana, micheto uye makona zvakatenderera, izvo zvinowanzoonekwa muzvikamu zvitete zvemadziro.

Zvikonzero:

1. Iron liquid okisijeni yakakomba, kabhoni nesilicon zvirimo zvakaderera, sulfuri yemukati yakakwira;

2. Kudzikira kupisa tembiricha, kunonoka kudururira kukurumidza kana kudira kwepakati.

Nzira dzekudzivirira:

1. Tarisa kana huwandu hwemhepo hwakanyanya;

2. Wedzera relay coke, gadzirisa kureba kwepasi pasi;

3. Kuvandudza tembiricha yekukanda uye kumhanya kwekukanda, uye usadimbure kuyerera panguva yekukanda.

Chikanganiso chechipiri: shrinkage yakasununguka

Zvimiro: pamusoro pemapores ane hutsinye uye haana kuenzana, ane dendritic crystals, concentrated pores for shrinkage, maduku akapararira nokuda kwe shrinkage, anowanzoonekwa mumanode anopisa.

Zvikonzero:

1. Zvinyorwa zvekabhoni uye silicon zvakanyanyisa, shrinkage yakakura, riser feeding haina kukwana;

2. Tembiricha yekudurura yakanyanya uye shrinkage yakakura;

3, mutsipa wekusimudza wakareba, chikamu chidiki kwazvo;

4, tembiricha yekukanda yakadzikira, kusanaya kwemvura kwesimbi yemvura, kunokanganisa kudya;

Nzira dzekudzivirira:

1. Kudzora kemikari yesimbi liquefaction kudzivirira yakaderera kabhoni uye nesilicon content;

2. Kunyatsodzora tembiricha yekudira;

3, inonzwisisika dhizaini inosimuka, kana zvichidikanwa, nesimbi inotonhora, kuve nechokwadi chekutevedzana kwekusimba;

4. Wedzera zviri mukati bismuth zvakakodzera.

Chirema chetatu: kupisa kunopisa, kutonhora kutsemuka

Zvimiro: Kupwanya kunopisa kunotsemuka pamwe nemuganho wezviyo pakupisa kwepamusoro, nechimiro chakaomarara uye oxidizing ruvara. Mutswero wemukati unopisa unowanzogara pamwe ne shrinkage cavity.

Cold crack inoitika pakadzika tembiricha, transgranular fracture, flat shape, metallic luster kana zvishoma oxidized surface.

Zvikonzero:

1, solidification process shrinkage yakavharwa;

2, zviri mukati kabhoni musimbi yemvura yakadzikira, zvirimo nesarufa zvakanyanyisa, uye tembiricha yekudurura yakanyanya;

3, liquid iron gasi rinenge rakakura;

4. Zvikamu zvakaoma zvakazara kare.

Nzira dzekudzivirira:

1, kuvandudza mhando, musimboti wemvumo;

2. Chikamu chikuru chekabhoni hachifaniri kunge chiri pasi pe2.3%;

3, chengetedza zviri mukati mesarufa;

4, cupola kusvika muovheni yakazara, mhepo yemhepo haigone kuve yakakura kwazvo;

5, kudzivirira kukanda tembiricha yakawandisa, uye vandudza kutonhora kumhanyisa, kuitira kunatsa zviyo;

6. Dzora kupisa kwekutakura.
