Noi Nui
- ʻO ka hoʻoheheʻe ʻana i ka calcium carbide
- Ka hana ʻana o Carborundum
- ʻO ka hoʻomaʻemaʻe corundum
- ʻO nā metala kakaʻikahi e hoohehee ana
- Ferrosilicon mea kanu refractory
ʻO ka hāʻawi ʻana a me ka hoʻohana ʻana no nā Electrodes Graphite
1. E hoʻohana i nā mea hoʻokiʻekiʻe kūikawā i ke ola i ka electrode graphite e pale i ka pōʻino i ka wā o ka lawe ʻana. (e nānā i ka pic1)
2. Pono e mālama ʻia ka electrode Graphite mai ka hoʻomaʻemaʻe ʻana a i ʻole ka pulu e ka ua, ka hau, e mālama ʻia i maloʻo. (e ʻike i ka pic2)
3. E nānā pono ma mua o ka hoʻohana ʻana e hōʻoia i ke kumu a me ka nipple thread i kūpono no ka hoʻohana ʻana, me ka nānā ʻana no ka pitch, plug. (see pic3)
4. E hoʻomaʻemaʻe i ka nipple a me nā kumu i nā kaula me ka ea paʻa.
5. Ma mua o ka hoʻohana ʻana, pono e hoʻomaloʻo ʻia ka electrode graphite i loko o ka umu, ʻo ka mahana maloʻo e emi iho ma mua o 150 ℃, ʻoi aku ka manawa maloʻo ma mua o 30 mau hola. (ʻike i ka pic5)
6. Pono e hoʻopili pono ʻia ka electrode Graphite me ka torque paʻa pono.
7. No ka pale ʻana i ka haʻihaʻi electrode graphite, e kau i ka hapa nui ma ke kūlana haʻahaʻa a me ka hapa liʻiliʻi ma ke kūlana kiʻekiʻe.
