Liyini izinga lokushisa lokubumba le ukufakwa kwesithando somlilo?

1. Izinga lokushisa lokuqala lokukhanga lesithando sokushisa lokungeniswa:

Lapho izinga lokushisa lokuqala lokubunjwa kwesithando sokushisa lokungeniswa liphezulu, ukuguqulwa kwepulasitiki yezinto zensimbi kuphezulu, ukumelana kuncane, amandla e-kinetic asetshenziswa ngesikhathi sokuguqulwa mancane, futhi ubuchwepheshe bokucubungula obunenani elikhulu lokuguquguquka bungasetshenziswa. Kodwa-ke, ukushisa kokushisa kwesithando sokushisa kwe-induction kuphezulu kakhulu, okungabangeli kuphela i-air oxidation ejulile kanye nokwanda kwekhabhoni, kodwa futhi kubangela ukushisa okungaphezulu nokushisa ngokweqile. Lapho kunqunywa izinga lokushisa lokuqala lokubumba kwesithando sokushisa sokungeniswa, into yokuqala okufanele yenziwe ukuqinisekisa ukuthi izinto zensimbi azibangeli ukushisa ngokweqile nokushiswa ngokweqile, futhi ngezinye izikhathi futhi kunqunyelwe isigaba esincibilikisiwe sokushisa okuphezulu. Ngensimbi ye-carbon, ukuze kuvinjwe ukushisa ngokweqile nokushiswa ngokweqile, izinga lokushisa lokuqala nokuphela lokubumba ngokuvamile lingaphansi kuka-130-350 ° C kunomugqa we-solidus womdwebo wesigaba se-iron-carbon.

Izinga lokushisa lokuqala lokukhanga lesithando sokushisa lokungeniswa kumele liphinde lilungiswe ngokufanele ngokwemibandela ethile. Uma kusetshenziswa ukwakhiwa kwesando esinesivinini esikhulu, izinga lokushisa lomphumela we-thermoelectric elibangelwa ukuguqulwa kwesivinini esikhulu lingase libangele ukuthi i-billet ishiswe ngokweqile. Ngalesi sikhathi, izinga lokushisa lokuqala lokukhanga kufanele libe ngaphezulu kune Ngokuvamile, izinga lokushisa lokuqala lokubumba licishe libe ngu-150°C ngaphansi.

2. Izinga lokushisa lokugcina lokukhanga lesithando sokushisa lokungeniswa:

Izinga lokushisa lokugcina lokukhanga lesithando sokushisa lokungeniswa liphezulu kakhulu. Ngemuva kokumiswa kokwakhiwa, i-crystal yangaphakathi yokubumba izokhula futhi, futhi isakhiwo sokusanhlamvu esimahhadla sizovela noma isigaba sesibili sizoncibilika, sinciphise izakhiwo ezibonakalayo zokubumba. Uma izinga lokushisa lokugcina lokufakelwa kwesithando sokushisa lokungeniswa liphansi kunokushisa kokuqina komsebenzi, ukuqina komsebenzi obandayo kuzokwenzeka ngaphakathi kwe-billet yokuqamba, okuzonciphisa ukuguquguquka kwepulasitiki futhi kuthuthukise kakhulu ukumelana ne-deformation. Kukhona ukucindezeleka okukhulu kwangaphakathi, okubangela ukubunjwa kuqhekeke phakathi nayo yonke inqubo yokupholisa amanzi noma inqubo yesigameko. Ngakolunye uhlangothi, ukunwetshwa kokushisa okungaphelele kuzoholela ezindleleni zokubumba ze-asymmetrical. Ukuze kuqinisekiswe ukuthi umsebenzi wokuqinisa umsebenzi ngaphakathi kwe-forging ngemuva kokufoja, izinga lokushisa lokugcina lokubumba lesithando sokushisa lokungeniswa ngokuvamile liphakeme ngo-60-150 ° C kunokushisa kokuqina komsebenzi wensimbi. Ukumelana ne-deformation yezinto zensimbi kuvame ukusetshenziswa njengesisekelo esibalulekile sokunquma izinga lokushisa lokugcina lokubumba lesithando sokushisa sokungeniswa.
