Uthini umxholo wehydrogen kwintsimbi etyhidiweyo ngokunyibilikiswa kwesithando somlilo?

Kwintsimbi ye-grey cast, i-hydrogen yinto enobungozi, umxholo ophantsi, ungcono. Ngenxa yomxholo ophezulu wekhabhoni kunye ne-silicon kwi-iron cast, i-solubility ye-hydrogen kubo iphantsi. Kwintsimbi etyhidiweyo enyibilike kwi-cupola, umxholo we-hydrogen ngokuqhelekileyo ngu-0.0002 ~ 0.0004%. Kwintsimbi etyhidiweyo enyibilikisiweyo yi-induction melting furnace, ngenxa yokuba ujongano phakathi kwesinyithi kunye negesi yesithando somlilo incinci, umxholo we-hydrogen ungaphantsi, malunga ne-0.0002%. I-hydrogen eveliswa ngokuphosa ayinakwenzeka ukuba ibangele i-porosity kunye nemingxuma ekujuleni.
