ʻO ka graphite electrode

ʻO ka graphite electrodehana nui ia me ka petroleum coke a me ka nila coke e like me nā mea maka a me ka asphalt lanahu e like me ka mea hoʻopaʻa ma o ka calcination, batching, kneading, molding, roasting, graphitization and machining. He mea alakaʻi ia e hoʻokuʻu i ka ikehu uila ma ke ʻano o ka uila i loko o ka umu ahi arc e wela a hoʻoheheʻe i ka uku o ka umu.

E like me kāna helu helu maikaʻi, hiki ke hoʻokaʻawale ʻia i ka mana graphite electrode High power graphite electrode a me ka ultra-high power graphite electrode ʻO ka mea nui no ka hana graphite electrode ka petroleum coke. Hiki ke hoʻohui ʻia kekahi o nā coke asphalt i ka electrode graphite mana maʻamau. ʻAʻole ʻoi aku ka nui o ka sulfur o ka coke petroleum a me ka asphalt coke ma mua o 0.5%. Hoʻohui ʻia ka coke asphalt a hoʻohana ʻia ʻo Needle coke e hana i ka mana kiʻekiʻe a i ʻole ka mana kiʻekiʻe kiʻekiʻe graphite electrode. ʻO ka piʻi ʻana o ka paʻakikī o ka mold geometry a me ka hoʻololi ʻana o nā noi huahana e alakaʻi i nā koi kiʻekiʻe a kiʻekiʻe aʻe no ka hoʻokuʻu pololei ʻana o ka mīkini spark.

ʻO nā mea maikaʻi o ka graphite electrode he maʻalahi machining, kiʻekiʻe kiʻekiʻe o ka wehe ʻana o EDM a me ka liʻiliʻi o ka graphite. No laila, hāʻawi kekahi hui i hoʻokumu i nā mea kūʻai aku i ka mīkini uila, a hoʻohana i ka electrode graphite. Eia hou,ʻaʻole hiki ke hanaʻia kekahi mau electrodes me nāʻano kūikawā i ke keleawe, akā,ʻoi aku ka maʻalahi o ka graphite, a ua kaumaha ka electrode keleawe,ʻaʻole kūpono i ka hanaʻana i nā electrodes nui. Ma keʻano laulā, ʻoi aku ka wikiwiki o ka hana me ka graphite electrode 58% ma mua o kēlā me ka electrode keleawe. Ma kēia ala, hoʻemi nui ʻia ka manawa hana a hoʻemi ʻia ke kumukūʻai hana ʻO kēia mau mea e hoʻonui ai i nā mea kūʻai aku e hoʻohana i nā electrodes graphite.

ʻO ka pōʻaiapili hana o ka electrode graphite maʻamau ma kahi o 45 mau lā, ʻoi aku ka lōʻihi o ka hana ʻana o ka ultra-high power graphite electrode ma mua o 70 mau lā, a ʻoi aku ka lōʻihi o ka hana ʻana o ka graphite electrode hui e koi ana i ka impregnation lehulehu. Pono ka electrode ma kahi o 6000kW · h o ka ikehu uila, mau tausani cubic mika o ke kinoea a i ʻole kinoea maoli, a ma kahi o 1t o ka coke metallurgical. nā ʻāpana a me ka pauka coke metallurgical.
