Ama-nozzles we-refractory tundish nama-stopper rods

Izinti zokumisa: Ku-tundish yemishini yokuphonsa eqhubekayo, ama-plug abalulekile asetshenziswa kabanzi. Igesi evikelayo engenzi lutho ikhipha imbobo encane ekhanda le-plug rod, engavimbela i-aluminium oxide ukuthi ifakwe eduze kwendawo yokuvala yembobo yamanzi, noma yehlise inani layo lokuhlanganisa, futhi ihambise indawo yokunqwabelana phansi. Ukuze kwandiswe impilo yekhanda lepulaki ukuze kube lula ukuthululwa kwe-multi-furnace okuqhubekayo, amakhanda epulaki ane-zirconia multilayer noma izinduku ezigcwele ze-plug zirconia zisetshenziswa ku-tundish ye-slab caster.
Imibhobho ye-Tudish: Impahla yama-nozzles e-tundish ikhethwa ngokusho kohlobo lwensimbi ethelwe, lapho uthela i-carbon steel evamile, ungasebenzisa i-mullite nozzle equkethe i-Al2O3 70 ~ 75%. Lapho kuthululwa insimbi esike kalula, i-magnesium oxide noma i-zirconia nozzles ingasetshenziswa. Lapho uthela insimbi ephezulu ye-manganese, i-aluminium graphite ephezulu noma i-zirconia nozzles ingasetshenziswa.
