Umthelela wokushisa okushisa kanye nesikhathi sokufakelwa kwenqubo yokwenziwa kwama-ingots ensimbi.Ukushisa kokushisa kanye nesikhathi sokufaka amapharamitha amabili ayinhloko enqubweni yokwenza izinsimbi zensimbi, ezithinta ngokuqondile i-plasticity ye-blank kanye nekhwalithi yomkhiqizo wokugcina.Lapho ukhetha izinga lokushisa elifanele lokushisa, kuyadingeka ukucabangela ukwakheka kwamakhemikhali ensimbi kanye nezidingo zenqubo yokubumba.
Okokuqala, ake sithole ukuqonda okujulile komphumela wokushisa okushisa kuma-ingots ensimbi.Ukushisa okwedlulele kokushisa kungase kubangele izinhlamvu ezingaphakathi kwe-ingot yensimbi ukuthi zikhule ngokushesha kakhulu, ngaleyo ndlela kunciphise ipulasitiki yezinto.Ngakolunye uhlangothi, uma izinga lokushisa lokushisa liphansi kakhulu, lingase liholele ekushiseni okunganele, okuholela ekusabalaliseni izinga lokushisa okungalingani kwe-ingot yensimbi futhi ngaleyo ndlela kuthinte ikhwalithi ye-forgings.Ngakho-ke, ukukhetha izinga lokushisa elifanele lokushisisa kubalulekile ukuze uqinisekise ukuthi ingot yensimbi ifinyelela kupulasitiki odingekayo.
Ngokusho kwebhukwana lokubumba, izinga lokushisa lokushisa lokubumba ama-ingots ensimbi kufanele ngokuvamile libe phakathi kuka-1150 no-1270 ℃.Kodwa-ke, ezimweni lapho isilinganiso sokubumba singaphansi kuka-1.5, ukulungiswa okuhambisanayo kufanele kwenziwe.Isibonelo, kumamaki ensimbi ajwayelekile, izinga lokushisa elinconywayo liyi-1050 ℃ lapho isilinganiso sokubumba singu-1.5-1.3.Ezimeni lapho isilinganiso sokubumba singaphansi kuka-1.3 noma singekho isilinganiso sokuqamba endaweni, kunconywa ukwehlisa izinga lokushisa libe ngu-950 ℃.
Ngaphezu kokushisa okushisa, isikhathi sokufakelwa kabusha singenye yemingcele ebalulekile enquma ipulasitiki kanye nokufana kwezinga lokushisa kwama-ingots ensimbi.Ubude besikhathi se-insulation buthinta ngokuqondile ukuthi ingxenye ephakathi ye-ingot yensimbi ingafinyelela izinga lokushisa lokubumba futhi iqinisekise ukufana kokusabalalisa kwezinga lokushisa ezingxenyeni ezihlukahlukene.Isikhathi eside se-insulation singashintsha kancane kancane izinga lokushisa langaphakathi le-ingot yensimbi, ngaleyo ndlela kuthuthukiswe i-plasticity ye-ingot futhi kunciphise ukuguquguquka kanye nokukhubazeka kwe-forging.Ngakho-ke, lapho uklama izinqubo zokubumba, kuyadingeka ukunquma ngokunengqondo isikhathi sokufaka ukuze kuhlangatshezwane nezidingo zokuqamba kanye namazinga ekhwalithi.
Kafushane, izinga lokushisa lokushisa kanye nesikhathi sokubamba kuyimingcele ebaluleke kakhulu enqubweni yokubumba yensimbi yensimbi.Ngokukhetha izinga lokushisa elifanele lokushisa kanye nesikhathi sokufaka esinengqondo, kungaqinisekisa ukuthi ingot yensimbi ithola ngokugcwele ipulasitiki edingekayo futhi iqinisekise ukufana kwezinga lokushisa ezingxenyeni ezihlukahlukene.Ngakho-ke, kuma-ingots ensimbi amakhulu, kungcono ukwenza ukushaja kwe-ingot eshisayo ngemva kokudilizwa ukuze kugwenywe ukwanda kweziphambeko zangaphakathi kanye nengozi yokuphuka kwe-ingot okubangelwa ukucindezeleka okushisayo nesakhiwo okukhiqizwa lapho kupholiswe ekamelweni lokushisa.
