Refractory tundish nozzles uye zvivharo tsvimbo

Stopper tsvimbo: Pa tundish yeanoramba achikanda michina, akabatanidzwa plugs anoshandiswa zvakanyanya. Iyo inert inodzivirira gasi inoburitsa kubva mugomba diki mumusoro weplug tsvimbo, iyo inogona kudzivirira iyo aluminium oxide kuti isaisa pedyo nenzvimbo yekuvharira yechiteshi chemvura, kana kuderedza kuunganidzwa kwayo, uye kufambisa nzvimbo yekuunganidzira pasi. Kuti uwedzere hupenyu hwemusoro we plug kuti ufambise kudira kwakawanda-choto kunoramba kuchidurura, plug misoro ine zirconia multilayer kana yakazara zirconia plug rods inoshandiswa pane tundish ye slab caster.
Tudish nozzles: Zvinhu zvetundish nozzles zvinosarudzwa zvichienderana nerudzi rwesimbi yakadirwa, kana uchidira general carbon simbi, unogona kushandisa mullite nozzle ine Al2O3 70 ~ 75%. Pakudurura simbi yakareruka, magnesium oxide kana zirconia nozzles inogona kushandiswa. Paunenge uchidira yakakwira manganese simbi, yakakwira aluminium graphite kana zirconia nozzles inogona kushandiswa.
