Daim ntawv thov ntawm silicon carbide rau casting:
1. Tiv thaiv cov nag lossis daus ntawm carbides, nce cov ferrite, thiab txo cov pob dawb;
2. Txhim kho qhov kev ua tau zoo thiab kev ua haujlwm zoo;
3. Ua kom fluidity, ruaj khov ntawm cov hlau molten, thiab tiv thaiv kev sib cais;
4. Txo cov phab ntsa thickness rhiab heev, ua rau cov qauv ntom thiab txiav nto du;
5. Txhim kho graphite nucleation muaj peev xwm thiab nce graphite core;
6. Rau ductile hlau, nws yog ib tug haib deoxidizer, uas yuav txo tau tus nqi ntawm nodularizing tus neeg sawv cev ntxiv thiab txhim kho tus nqi nodularizing;
7. Restore rusty seem thiab alloys kom txo tau tus nqi ntawm molten hlau;
8. Tshem tawm cov txheej txheem oxidation ntawm cov hlau molten, txo cov cua sov ntawm phab ntsa oxidation, thiab txuas lub neej ntawm cov phab ntsa ntawm lub cub tawg los ntawm 30%;
9. Muaj zog deoxidation kom huv si molten hlau.
Yuav ua li cas siv silicon carbide rau casting:
Tus nqi ntawm silicon carbide ntxiv yog nyob ntawm qhov nyiaj ntawm silicon uas tuaj yeem nqus tau los ntawm 1KG ntawm silicon carbide hauv cov hlau molten: 0.5KG
Kev suav (tus nqi nqus yog kwv yees li 90%), qhov xwm txheej tshwj xeeb yog raws li qhov tseeb ntawm qhov chaw!
Thaum tus nqi ntawm silicon ntxiv rau lub cub tawg ntawm cov hlau molten raug xam, nws yog ib qho yooj yim los xam cov nyiaj ntawm silicon carbide xav tau.
Yog hais tias tus txheej txheem tej yam kev mob tso cai, lub molten hlau yuav tsum tau overheated ntawm 1550 degree rau 5 feeb kom zoo dua nqus.
Txoj kev ntxiv yog qhov pib zoo ib yam li cov txheej txheem ntxiv ntawm tus neeg sawv cev carburizing. Khi lub cev hnyav silicon carbide nyob rau hauv ib lub hnab woven, muab tso rau hauv lub molten hlau nyob rau hauv lub cub tawg, thiab smelt lub npog cov ntaub ntawv, tab sis qhov kev txiav txim yog tom qab ntxiv tus neeg sawv cev carburizing.
