A Ipu ʻōpala LF(ipu ʻōpala umu ladle) a i ʻoleIpu ʻōpala VD(ʻeke slag degassing vacuum) nā limaʻōpala hana- ʻaʻole ka ʻōpala wela kiʻekiʻe a ʻino mai EAF a i ʻole BOF, akā he hui pū ʻana o ka lime, fluorspar, a me nā mea hoʻohuihui i hoʻolālā ʻia e hoʻomaʻemaʻe i ke kila heheʻe.

He aha ka mea e ʻokoʻa ai nā ipu slag LF/VD?

1. ʻOi aku ka haʻahaʻa o ka mahana o ka slag (~1,500°C vs 1,650°C no EAF), akā ʻoi aku ka lōʻihi o ka manawa paʻa- i kekahi manawa he 60-90 mau minuke no kēlā me kēia wela. Pono ka ipuhao e kū i ke ahihoʻololi koloma ke ana wela kiʻekiʻe mau loa.

3. Hoʻokau ka Vacuum degassing (VD) i kahi koi kūikawā: hiki ke waiho ʻia ka ipuhao slag ma lalo o ka vacuum (0.5–1 torr) no nā manawa pōkole. Hiki i kekahi microporosity i loko o ka hoʻolei ʻana ke puka i waho o ke kinoea, e alakaʻi ana ika hoʻokumu ʻia ʻana o ka pehu i loko o ke kilaa i ʻole - ʻoi aku ka ʻino -ka pahū ʻana o ka ipuhaoinā loaʻa kahi lua nui.

Nā Nīnau i Nīnau Pinepine ʻia (FAQ) - LF/VD Kūikawā

Q: No ke aha he mea nui ka nui o ka hydrogen no nā ipu slag?
A: I ka wā o ka hoʻohemo ʻana i ke kinoea me ka vacuum, hiki i ka hydrogen i hoʻoheheʻe ʻia i loko o ka hoʻoheheʻe kila ke hoʻolaha a hui hou i loko o ka hydrogen molekala ma nā hoʻokomo ʻole metala. Hoʻokumu kēia i ke kaomi kūloko, e alakaʻi ana i ka blistering a i ʻole ka haki ʻana - i kekahi manawa i kapa ʻia ʻo "hydrogen flaking." He maʻalahi nā ipu LF/VD no ka mea ua paʻa lākou ma lalo o ka vacuum no nā manawa lōʻihi.

H: Hiki iā ʻoe ke hōʻoia i ka nui o ka hydrogen i <1.0 ppm?
ʻAe, akā koi ʻia ka hoʻomaʻamaʻa hoʻoheheʻe kūikawā (vacuum induction melting a i ʻole electroslag remelting) a ʻoi aku ke kumukūʻai. No ka hapa nui o nā noi, ua lawa ka 1.5 ppm.

Q: Ke hāʻawi nei ʻoe i ka hoʻāʻo leaka vacuum?
A: ʻAe, hana mākou i ka hoʻāʻo ʻana i ka liki helium ma ke noi a hoʻopuka i kahi palapala hōʻoia e like me ISO 20485. Hoʻohiki mākou i ka helu liki <1×10⁻⁶ mbar·l/s.

Q: Pehea ka pinepine e hoʻololi ʻia ai nā ipu LF slag?
A: ʻO ka maʻamau i kēlā me kēia 3-5 mau makahiki, ma muli o nā pōʻaiapuni. ʻO ke ʻano kolo ka mea nui e kaupalena ana i ke ola. Hiki i ka nānā ʻana o ka UT makahiki ke ʻike i nā lua kolo mua.

Q: Hiki iā ʻoe ke hoʻolako i nā ipu slag me kahi ʻaʻahu ea hoʻoluʻu?
A: No nā noi LF e pono ai ka hoʻomaʻalili wikiwiki ma mua o ka hoʻohana hou ʻana, hiki iā mākou ke hoʻolālā i kahi ʻaʻahu ea hoʻohui (pū kila waho me nā kahawai ea). Hoʻemi kēia i ka manawa hoʻomaʻalili mai 90 mau minuke a i 20 mau minuke.

Q: Ua kūlike anei kāu mau ipu hao LF me nā ʻōnaehana ʻike pae hao aunoa?
ʻAe. Hāʻawi mākou i kahi papa hoʻopaʻa pālahalaha ma ka lihi no kahi sensor radar a laser paha. A i ʻole, hiki iā mākou ke hoʻokomo i nā thermocouples no ka ʻike ʻana i ka papa slag.

Q: Ke hāʻawi nei ʻoe i ke aʻo ʻana no ka nānā ʻana i ka ipu LF?
ʻAe, hāʻawi mākou i hoʻomaʻamaʻa hoʻokahi lā ma kahi no kāu hui mālama: UT o nā trunnions, nā pae nānā maka, a me nā kaʻina hana hoʻoponopono māwae.

Q: He aha ka palapala hoʻokō maʻamau no ka ipuhao LF/VD?
A: 24 mahina a i ʻole 10,000 mau pōʻaiapuni - ʻo ka mea mua. No ka lawelawe vacuum (me ka hoʻāʻo leak), ua hoʻolōʻihi ʻia ka palapala hoʻokō i 36 mau mahina e kūʻē i ka haki ʻana o ka hydrogen.
