550mm kiʻekiʻe mana graphite electrode
Hana ʻia ʻo HP graphite electrode i ka coke petroleum a me ka coke needle, hiki iā ia ke lawe i ka nui o kēia manawa 18-25A/cm2. Hoʻolālā ʻia ia no ka hana kiʻekiʻe uila arc furnace steel-making.
ʻO nā ʻano hana hana kila o kēia wā ka mea nui i ka hana hao mea hoʻololi a me ka hana hao umu uila. ʻO ka ʻokoʻa koʻikoʻi ma waena o ke ʻano hana hao umu uila a me ke ʻano hana hoʻololi ʻana ʻo ia ka hoʻohana ʻana i ka ikehu uila e like me ke kumu wela, a ʻo ke ʻano hana hana hao uila ka mea maʻamau.
Hoʻokumu ʻia ka EAF steelmaking ma ka uila arc i hana ʻia e ka hoʻokuʻu ʻana ma waena o ka electrode a me ka hoʻopiʻi, e hoʻohuli i ka ikehu uila i ka ikehu wela i ke kukui arc, a hoʻohana i ka hana pololei o ka radiation a me ka arc e wela a hoʻoheheʻe i ka metala a me ka slag e honi. kila a me nā huila like ʻole.

graphite electrode haku mele
1. He ʻeleʻele a porous ka Petroleum coke, ʻo ke kalapona ka mea nui, a he haʻahaʻa loa ka ʻike lehu, ma lalo o 0.5%.
Hiki ke hoʻokaʻawale ʻia ʻo Petroleum coke i ʻelua ʻano o ka coke maka a me ka coke calcined e like me ka mahana mālama wela. Loaʻa i ka mea mua ka nui o nā mea volatile a he haʻahaʻa ka ikaika mechanical. Loaʻa ka coke calcined ma ka calcining i ka coke maka.
Hiki ke hoʻokaʻawale ʻia ka Petroleum coke i loko o ka coke sulfur kiʻekiʻe (me ka sulfur content ma luna o 1.5%), ka coke sulfur medium (me ka sulfur content 0.5% -1.5%), a me ka coke sulfur haʻahaʻa (me ka sulfur ma lalo o 0.5%) e like me ka pae sulfur. Hana ʻia nā electrodes graphite a me nā huahana graphite artificial me ka hoʻohana ʻana i ka coke sulfur haʻahaʻa.
2.Needle coke he ʻano coke kiʻekiʻe me ka ʻike kikoʻī fiber, ʻoi aku ka haʻahaʻa haʻahaʻa haʻahaʻa hoʻonui a me ka maʻalahi graphitization. No laila, ʻo ka nila coke he mea kī nui no ka hana ʻana i nā electrodes graphite kiʻekiʻe a i ʻole ultra-kiʻekiʻe i hōʻike ʻia me ka resistivity haʻahaʻa, liʻiliʻi ka hoʻonui ʻana i ka wela, a me ke kūpaʻa haʻalulu maikaʻi.
ʻO 3.Coal pitch kekahi o nā huahana nui o ka coal tar ma hope o ka hana hohonu. He hui ia o ka nui hydrocarbons. Hoʻohana ʻia ka pitch lanahu ma ke ʻano he mea hoʻopaʻa a hoʻopuʻi. He hopena nui kāna hana i ka maikaʻi o nā electrodes graphite.
