Refractory zvidhinha ndeye ceramic zvinhu izvo zvinowanzo shandiswa munzvimbo dzakanyanya kupisa nekuda kwekushaikwa kwekupisa uye nekuti insulator yakanaka inoderedza kurasikirwa kwesimba. Refractory brick inowanzo umbwa nealuminium oxide uye silicon dioxide. Inonziwo "zvidhinha zvemoto."

Kune nzira mbiri huru dzekugadzira ferroalloys, imwe ndeye kushandiswa kwekabhoni mukubatana nemaitiro akakodzera ekunyungudutsa, uye imwe ndeye metallothermic kuderedza nedzimwe simbi. Iyo yekare maitiro anowanzo kubatanidzwa nebatch mashandiro, nepo ekupedzisira achinyanya kushandiswa kutarisa kune akasarudzika epamusoro-giredhi alloys anowanzo ane yakaderera kabhoni yemukati.

Metal casting inzira yechinyakare yave yakakosha kubudiriro yevanhu kwemazana emakore. Kubva pakugadzira zvivezwa zvakaoma kusvika pakugadzira yakaoma indus

Ferrosilicon yakakosha ferroalloy inoshandiswa zvakanyanya musimbi metallurgy uye foundry indasitiri. Ichi chinyorwa chichazivisa zvizere magadzirirwo ekugadzirwa kweferrosilicon, kusanganisira kusarudzwa kwezvinhu, nzira dzekugadzira, kuyerera kwemaitiro, kutonga kwemhando uye kukanganisa kwezvakatipoteredza.

Alloy musanganiswa kana kuti solid solution ine simbi. Saizvozvo, ferroalloy musanganiswa wealuminium yakasanganiswa nezvimwe zvinhu zvakaita semanganese, alum.

Silicon simbi poda chinhu chakakosha muindasitiri yekugadzira simbi. Inoshandiswa zvakanyanya sealloying agent mukugadzirwa kwemhando dzakasiyana dzesimbi. Iine yakasarudzika zvimiro uye mabhenefiti, silicon simbi poda inoita basa rakakosha mukusimudzira kunaka uye kuita kwezvigadzirwa zvesimbi. Ichi chinyorwa chine chinangwa chekupa kuongorora kwakadzama kwesilicon simbi poda yekugadzira simbi, kuratidza maitiro ayo, mashandisirwo, uye zvakanakira izvo zvinopa kuindasitiri yesimbi.
