Izizathu zokuvuza kwesithando somlilo sokungeniswa

Ingozi evamile emzimbeni wesithando somlilo we-induction melting furnace ivuza esithandweni. Uma kuba nengozi, uma kungekho zinyathelo ezithathwayo, kuzobangela ukugqashuka kweshubhu lekhoyili, futhi insimbi encibilikisiwe nesipholile kuzoqhuma. s isizathu:

1. Izici zekhwalithi zezinto ezisetshenziswa ekwakhiweni kwesithando somlilo: ngokuvamile zisebenzisa izinto zokwenziwa kwesithando somlilo we-quartz. Okuqukethwe kwe-silicon yesihlabathi se-quartz ne-quartz powder kufanele kube ngaphezu kuka-99.5%, ngamakristalu anamafutha, obala futhi angenakho ukungcola. Ngokuvamile sebenzisa isihlabathi se-quartz esihlanzekile kakhulu (okuqukethwe kwe-silicon 99.85%, ubulukhuni 8, ukuminyana okungu-2.65, i-refractoriness 1850 degrees).

2. Izinto ezihlanganisayo ezisetshenziswa ekwakhiweni kwesithando somlilo: izindlela zokwakha zesithando somlilo ngokuvamile zisebenzisa i-boric acid njengesibopho. I-boric acid inezinzuzo kanye nokubi kokubili: inzuzo ukuthi ukubopha kuyashesha ekushiseni okuphansi, ngokuvamile kuqala ku-600-700 degrees; okubi wukuthi ayimelani nezinga lokushisa eliphezulu kanye nokuguguleka komhlabathi. Ngaphansi kwezimo eziphakeme zokushisa, ingxenye engezansi yodonga lwesithando somlilo izobangela isenzakalo sokubilisa , Inombolo yokushisa esetshenzisiwe iyancipha kakhulu. Kunconywa ukusebenzisa i-boric acid njengesibophezelo, ngoba i-boric acid inezici zokubopha izinga lokushisa eliphezulu, izinga eliphezulu lokuncibilika, ukumelana nokushisa okuphezulu, nokumelana nokuguguleka.
