ʻElekoda grafit

ʻElekoda grafitHana nui ʻia me ka petroleum coke a me ka nila coke ma ke ʻano he mea maka a me ka lanahu asphalt ma ke ʻano he mea hoʻopaʻa ma o ka calcination, batching, kneading, molding, roasting, graphitization a me ka machining. He alakaʻi ia e hoʻokuʻu i ka ikehu uila ma ke ʻano o ka arc uila i loko o ka umu arc uila e hoʻomehana a hoʻoheheʻe i ka uku umu.

Wahi a kona helu kuhikuhi maikaʻi, hiki ke hoʻokaʻawale ʻia i ka electrode graphite mana maʻamau. ʻO ka electrode graphite mana kiʻekiʻe a me ka electrode graphite mana ultra-kiʻekiʻe. ʻO ka mea nui no ka hana ʻana i ka electrode graphite, ʻo ia ka petroleum coke. Hiki ke hoʻohui ʻia kekahi mau coke asphalt i ka electrode graphite mana maʻamau. ʻAʻole e ʻoi aku ka nui o ka sulfur o ka petroleum coke a me ka asphalt coke ma mua o 0.5%. Hoʻohui ʻia ka asphalt coke a me ka Needle coke e hana i ka electrode graphite mana kiʻekiʻe a i ʻole ka ultra-kiʻekiʻe. ʻO ka paʻakikī o ka geometry mold a me ka diversification o nā noi huahana e alakaʻi i nā koi kiʻekiʻe a kiʻekiʻe no ka pololei o ka hoʻokuʻu ʻana o ka mīkini spark.

ʻO nā pono o ka electrode graphite ka maʻalahi o ka mīkini ʻana, ka wikiwiki o ka wehe ʻana o EDM a me ka emi ʻana o ka pohō graphite. No laila, ʻo kekahi hui e hoʻokumu ana i nā mea kūʻai mīkini ʻālohilohi, e haʻalele i ka electrode keleawe a hoʻohana i ka electrode graphite. Eia kekahi, ʻaʻole hiki ke hana ʻia kekahi mau electrodes me nā ʻano kūikawā me ke keleawe, akā ʻoi aku ka maʻalahi o ka hiki ʻana i ka graphite, a he kaumaha ka electrode keleawe, ʻaʻole kūpono no ka hana ʻana i nā electrodes nui. Ma keʻano laulā, ʻoi aku ka wikiwiki o ka hana ʻana me ka electrode graphite ma mua o ka electrode keleawe. Ma kēia ʻano, ua hoʻemi nui ʻia ka manawa hana a ua hoʻemi ʻia ke kumukūʻai hana. ʻO kēia mau mea ke kumu o ka nui o nā mea kūʻai aku e hoʻohana i nā electrodes graphite.

ʻO ke kaʻina hana o ka electrode graphite mana maʻamau ma kahi o 45 mau lā, ʻoi aku ka nui o ke kaʻina hana o ka electrode graphite mana kiʻekiʻe ma mua o 70 mau lā, a ʻoi aku ka lōʻihi o ke kaʻina hana o ka hui electrode graphite e koi ana i ka impregnation he nui. Pono ka hana ʻana o ka electrode graphite mana maʻamau 1t ma kahi o 6000kW · h o ka ikehu uila, nā tausani mika cubic o ke kinoea a i ʻole ke kinoea kūlohelohe, a ma kahi o 1t o nā ʻāpana coke metallurgical a me ka pauka coke metallurgical.
