Amanqaku aphambili olawulo lwenkqubo xa kunyibilikiswa intsimbi etyhidiweyo kwisithando somlilo se-induction

Amanqaku aphambili olawulo lwenkqubo xa kucetyiswa ukuba kusetyenziswe ukuchithwa kwesithando somlilo ukunyibilikisa intsimbi etyhidiweyo ngolu hlobo lulandelayo:

1. Isixa se-ingots yehagu kwi-charge akufanele idlule i-20%, ngokukhethekileyo malunga ne-10%;

2. Kwi-recarburizer eyongeziweyo kunye nentlawulo, kungcono ukuba ube nomlinganiselo othile (40-55%) we-metallurgical silicon carbide;

3. Ukunyamekela ngokucokisekileyo unyango lwe-inoculation ngexesha lokucofa isinyithi, kwaye ukhethe izitofu ezifanelekileyo ngokwemiqathango ethile yokuvelisa yeshishini. Isixa se-inoculants esongeziweyo kufuneka sibe yi-0.1-0.2% ephezulu kunokuba ngexesha le-cupola smelting. Elona nani lifanelekileyo kufuneka liphumelele iziphumo zovavanyo lwangaphandle. Ngokuqinisekileyo;

4. Kufuneka ifakwe ngokukhawuleza ngexesha lokugalela;

5. Xa uvelisa i-castings eneemfuno eziphezulu, i-metallurgical silicon carbide kufuneka ifakwe kwisithando somlilo ukwenzela ukulungiswa kwangaphambili ngaphambi kokucofa.
