Mabasa e tundish nozzles

Tundish nozzle inoshandiswa kunyungudutsa simbi uye kudurura mu tundish. Kana ichinge ichishandiswa, inoda kumira tembiricha yakakwira uye inoshingirira kune yakanyungudutswa iron corrosion, kuitira kuderedza kukuvadzwa kune tundish nozzle. Kune akawanda marudzi uye zvigadzirwa zve tundish nozzle, uye zvakajairika zvinhu zve tundish nozzle is oxidation knot. Izvi zvinodaro nekuti oxidizer ine yakanaka yakakwirira tembiricha kuramba uye corrosion kuramba, iyo inogona kuvharira zvizere kukanganisa kwesimbi yakanyungudutswa.

Mabasa e tundish nozzle uye zvaanoda kune refractory zvinhu:

(1) Tundish inonyanya kuve mudziyo wekugamuchira, kuchengetedza uye kugoverazve mvura yeladle. Tundish metallurgy tekinoroji senge kugadzirisa tembiricha, kugadzirisa trace alloying zvinhu uye kuvandudza inclusions inogadzirwa zvishoma nezvishoma.

(2) Refractory zvinhu zvinodiwa kuti ive yakaderera refractoriness, asi inosungirwa kusapinda mukuora kwesimbi yakanyungudutswa slag uye yakanyungudutswa slag, ine yakanaka yekupisa kuvhundutsa kuramba, kuve nediki diki yekupisa, kuita kwakanaka kwekushisa kwekushisa, haina kusvibiswa kunyunguduka. simbi, uye zvive nyore kuisa uye kubvisa.
