Ukuze kuhlangatyezwane nemfuno yomthengi, iShijiazhuang dong huan enyibilikayo yentsimbi castings co., I-ltd iye yaphuhliswa izifakelo ezitsha zentsimbi ezinyibilikayo. Ukwakhiwa kweekhemikhali zemathiriyeli ekrwada sinokushwankathela.
Amaxabiso e-C, Si, CE kunye ne-Mg kufuneka ahlangabezane nemilinganiselo ephambili yokuphosa. Ubungakanani becandelo lokuphosa bumisela izinga lokupholisa lokusa, ngelixa ukwakheka kweekhemikhali kunye nesantya sokupholisa ngokudibeneyo kumisela ubume bemetallographic yemveliso.
Zombini i-ferrite cast iron kunye ne-pearlitic cast iron ifuna i-Si (ukutshintsha umxholo weSi kuthetha ukutshintsha i-CE) kunye ne-MN.
I-Castings ingahlelwa njengenye yee-substrates ezimbini ngokokwakheka kweekhemikhali, nto leyo ethetha ukuba kukho ubuncinane izithako ezine zokuphumeza ukwakheka kweekhemikhali ezinqwenelekayo ekuveliseni amanqanaba ahlukeneyo amacandelo abhityileyo kunye neendonga ezishinyeneyo.
Phawula:
1. Ubunzima bezithako ezahlukahlukeneyo bunokubalwa ngokuphindaphinda ubunzima bentsimbi etyhidiweyo eveliswa yi-% % yezithako ezongeziweyo.
2. Umxholo we-MN ubekwe ngamabomu kwinqanaba eliphantsi, kuba kwintsimbi ye-ferrite nodular, nangona umxholo uphantsi, unokukhuthaza ukuveliswa kwe-pearlite, kwi-pearlite, umxholo ophezulu we-MN kulula ukubangela ukuhlukana kwe-MN kwi. pearlite, usebenzisa Cu ukwenza ubulukhuni ukuhlangabezana neemfuno zangaphambili lukhetho olungcono.
3. I-Silicon carbide inokongezwa ukunciphisa i-oxidation yensimbi etyhidiweyo kwaye ikhusele i-furnace lining (imali eyongezelelweyo ngokubanzi yi-0.2%), inokudlala inxalenye yokunyuka kwe-C kunye ne-silicon effect.
4. Ireyithi yokufunxa ikakhulu ye-C kunye ne-Si.
