Mafura anowanzo kuvakwa achishandisa simbi akati wandei, imwe neimwe yakasarudzwa kune yayo chaiyo zvivakwa uye kukodzera kwepamusoro-tembiricha yekushandisa. Mamwe masimbi anoshandiswa muchoto anosanganisira:

1. Simbi: Simbi chinhu chinoshandiswa zvakanyanya mukuvakwa kwechoto nekuda kwesimba rayo, kusimba uye mutengo wakaderera. Carbon uye simbi isina tsvina inowanzoshandiswa kugadzira magomba echoto, zvimiro zvemukati uye zvimiro zvekutsigira.

2. Refractory metals: Refractory metals yakadai se molybdenum, tungsten, tantalum uye niobium inoshandiswa mukupisa kwekushisa kwechoto kushandiswa nekuda kwekunyanya kunyunguduka kwayo, simba pakupisa kwepamusoro, kupisa kwekushisa uye kusagadzikana kwekuora. Aya masimbi anowanzo shandiswa mukudziya zvinhu, zvikamu zvechoto, uye zvigadziriso.

3. Nickel-based alloys: Nickel-based high-temperature alloys anoshandiswa kune zvikamu zvechoto zvinoratidzwa kune tembiricha yepamusoro uye nzvimbo dzinopisa. Aya maalloys anopa kusimba kwepamusoro-tembiricha, oxidation kuramba, uye kugadzikana kwekupisa, zvichiita kuti ive yakakodzera kurapwa kwekupisa uye yakakwirira-tembiricha yekugadzirisa zvikumbiro.

4. Mhangura yemhangura nemhangura: Mhangura uye alloys ayo, akadai sendarira nendarira, anoshandiswa mune zvimwe zvikamu zvechoto, kunyanya mumashandisirwo anoda zvakanaka thermal uye magetsi conductivity. Mhangura inowanzoshandiswa muchoto coils uye magetsi ekubatanidza.

5. Cast Iron: Cast iron inoshandiswa mune mamwe marudzi echoto, kunyanya mumashandisirwo ayo anopisa conductivity uye kuramba kune kupisa kunotyisa kunobatsira. Inowanzoshandiswa pakuvaka mamwe marudzi ehuni dzemaindasitiri uye zvitofu.

Kusarudzwa kwesimbi dzekuvaka choto kunoenderana nezvinhu zvakasiyana-siyana, senge tembiricha yekushanda, rudzi rwemhepo muchoto, mashandisirwo chaiwo echoto, uye kufunga zvine chekuita nemutengo uye kuwanikwa. Simbi imwe neimwe ine zvakanakira uye zvisingakwanisi, uye kusarudzwa kwezvinhu kunoenderana nezvinodiwa zvechoto uye chinangwa chekushandisa.
