Abakhiqizi bemishini yokucisha imvamisa ephezulu chaza kafushane inqubo yokudonsa insimbi

1. Kuhlanganiswe ngokuphelele

Inqubo: Ukushisa ngaphezu kwe-Ac3 ukuya ku-30-50°C → ukulondolozwa kokushisa → ukupholisa kube ngaphansi kwama-degree angu-500 ngesithando somlilo → ukupholisa komoya ekamelweni lokushisa.

Inhloso: ukucwenga okusanhlamvu, ukwakheka okufanayo, ukuthuthukisa ipulasitiki nokuqina, ukuqeda ukucindezeleka kwangaphakathi, nokwenza kube lula ukukhanda.

2. Ukuncishwa kwe-Isothermal

Inqubo: ukushisa ngaphezu kwe-Ac3 → ukulondolozwa kokushisa → ukupholisa okusheshayo kumazinga okushisa e-pearlite → ukuhlala kwe-isothermal → ukuguqulwa kuya ku-P → ukupholisa komoya;

Inhloso: Ibid. Kodwa isikhathi sifushane, kulula ukusilawula, futhi i-deoxidation kanye ne-decarburization kuncane. (Ifanele i-alloy steel kanye nezingxenye ezinkulu ze-carbon steel ezino-A ozinzile kakhulu.

3. Ukuncishiswa kokuphamba

Umqondo: Kuyinqubo ye-spheroidizing cementite ensimbi.
