ʻO ka wehewehe pōkole:

Hoʻohana ʻia nā electrodes graphite no nā kapuahi arc uila, nā kapuahi ladle a me nā kapuahi arc submerged. Ma hope o ka hoʻoulu ʻia ʻana i ka hana kila EAF, Ma ke ʻano he alakaʻi maikaʻi, hoʻohana ʻia ia e hana i kahi arc, a hoʻohana ʻia ka wela o ke arc e hoʻoheheʻe a hoʻomaʻemaʻe i ke kila, nā metala non-ferrous a me kā lākou mau ala. He mea alakaʻi maikaʻi i kēia manawa i ka umu ahi arc, ʻaʻole heheʻe a hoʻoheheʻe i nā wela kiʻekiʻe, a mālama i kahi ikaika mechanical. Aia ʻekolu ʻano:RP 、HP, aUHP graphite electrode.

He aha ka graphite electrode?

Hoʻohana nui ʻia ka graphite electrode no nā umu ahi arc a me nā umu wela a me ke kūpaʻa ma ke ʻano he alakaʻi maikaʻi. I ke kumukūʻai o ka umu ahi arc steelmaking, ʻo ka hoʻohana ʻana i nā electrodes graphite e pili ana i ka 10%.

Hana ʻia ia me ka coke petroleum a me ka pitch coke, a ua hana ʻia nā māka kiʻekiʻe a me nā māka kiʻekiʻe kiʻekiʻe me ka coke nila. He haʻahaʻa ka lehu maʻiʻo, ka conductivity uila maikaʻi, ka wela, a me ka pale ʻana i ka corrosion, a ʻaʻole e hoʻoheheʻe a hoʻoheheʻe paha i nā wela kiʻekiʻe.

E pili ana i nā māka electrode graphite a me nā anawaena.

He ʻokoʻa nā māka a me nā anawaena o JINSUN. Hiki iā ʻoe ke koho mai nā māka RP, HP a i ʻole UHP, hiki ke kōkua iā ʻoe e hoʻomaikaʻi i ka hana o ka umu ahi arc, hoʻonui i ka pono hana, a hoʻonui i nā pono waiwai. Loaʻa iā mākou nā anawaena like ʻole, 150mm-700mm, hiki ke hoʻohana ʻia no nā hana hoʻoheheʻe ʻana o nā kapuahi uila o nā tonages like ʻole.

He mea nui ke koho pololei o ke ʻano electrode a me ka nui. He mea nui kēia i ka hōʻoia ʻana i ka maikaʻi o ka metala i hoʻoheheʻe ʻia a me ka hana maʻamau o ka umu uila arc.

Pehea e hana ai i ka eaf steelmaking?

Hoʻokomo ka graphite electrode i ke au uila i loko o ke kapuahi hana kila, ʻo ia ke kaʻina hana hana kila arc. Hoʻouna ʻia ke au ikaika mai ka mea hoʻololi umu ma o ke kaula i ka mea paʻa ma ka hopena o nā lima electrode ʻekolu a kahe i loko.

No laila, ma waena o ka hopena electrode a me ka hoʻopiʻi e puka mai kahi hoʻokuʻu arc, a hoʻomaka ka hoʻoheheʻe ʻana me ka hoʻohana ʻana i ka wela i hana ʻia e ke arc a hoʻomaka ka hoʻoheheʻe. E like me ka mana o ka umu uila, e koho ka mea hana i nā diameters like ʻole no ka hoʻohana ʻana.

No ka hoʻohana mau ʻana i nā electrodes i ka wā o ka hoʻoheheʻe ʻana, hoʻopili mākou i nā electrodes ma o nā nipples threaded. No ka mea ʻoi aku ka liʻiliʻi o ka ʻāpana keʻa o ka nipple ma mua o ka electrode, pono e loaʻa i ka nipple ka ikaika compressive kiʻekiʻe a me ka resistivity haʻahaʻa ma mua o ka electrode.

Eia kekahi, aia nā ʻano nui a me nā māka, e pili ana i kā lākou hoʻohana a me nā koi kikoʻī o ke kaʻina hana eaf steelmaking.
