Upper nozzles yog muab tso rau hauv lub qhov dej blocks hauv qab ladle los yog tundish hauv qab. Nws yog hloov ua ke nrog zoo blocks thaum kho cov ladles thiab tundish yog xav tau.
Ladle sab saum toj nozzles yog ua ke nrog swb rooj vag phaj thiab collector nozzle; Tundish Upper nozzles yog ua ke nrog cov nozzles qis.
Hom: Feem ntau muaj ob hom --- sab sauv nozzles rau swb rooj vag teeb thiab sab sauv nozzles rau tundish exchangeable nozzle.
Khoom siv:
Sab saum toj nozzle rau swb rooj teeb --- alumina carbon cov khoom
Upper nozzle rau exchangeable tundish nozzle - alumina carbon cov ntaub ntawv nrog zirconia ntxig
Txhawm rau ua tau raws li qhov xav tau sib txawv ntawm kev pabcuam lub neej thiab kev ua haujlwm, cov ntaub ntawv raug kho qee zaum. Cov ntaub ntawv hauv qab no yog txuas rau siv.
Muaj nuj nqi refractories rau nruam casting steel yog ib yam ntawm advanced refractories tsom rau cov hlau huv si. Nrog rau kev ua haujlwm refractories, molten steel txaus tswj tau zoo dua, thiab tuaj yeem tiv thaiv Oxygen thaum lub sij hawm casting.
Muaj nuj nqi refractories rau steel nruam casting feem ntau muaj xws li refractories los ntawm steel Ladle rau Tundish thiab Tundish rau tooj liab Mould Tube.
Muaj nuj nqi refractories feem ntau ua ke nozzles tsis muaj tus neeg sawv cev khi, yog li qhov ntev thiab qhov chaw ntawm cov refractories yog nruj me ntsis tswj kom phim ib leeg nruj.
Kev ua haujlwm ntawm kev ua haujlwm refractories feem ntau yog los ntawm steel Mechanism, raws li teev hauv qab no:
