Pehea e hiki ai i ka graphite ke pani i ke keleawe ma ke ʻano he electrode? Kaʻana like ʻia eʻO ka ikaika mechanical kiʻekiʻe Graphite Electrode Kina.
I nā makahiki 1960, ua hoʻohana nui ʻia ke keleawe ma ke ʻano he mea electrode, me ka helu ʻana o ka hoʻohana ʻana ma kahi o 90% a ʻo ka graphite ma kahi o 10% wale nō. I ke kenekulia 21, ua hoʻomaka ka nui o nā mea hoʻohana e koho i ka graphite ma ke ʻano he mea electrode. Ma ʻEulopa, ʻoi aku ma mua o 90% o ka mea electrode he graphite. ʻO ke keleawe, ʻo ia ka mea electrode nui i ka wā ma mua, ua aneane nalowale kona lihi ma luna o ka graphite. He aha ke kumu o kēia loli nui? ʻOiaʻiʻo, he nui nā pono o ka electrode graphite.
(1) ka wikiwiki o ka hana ʻana: ma ke ʻano laulā, ʻo ka wikiwiki o ka hana ʻana o ka mīkiniʻElekoda Graphite no ke kūʻai akuhiki ke 2 ~ 5 mau manawa wikiwiki ma mua o ke keleawe; Eia nō naʻe, ʻo ka edm he 2 ~ 3 mau manawa wikiwiki ma mua o ke keleawe, a ʻoi aku ka liʻiliʻi o ka mea i ka deformation. ʻO ke kiko palupalu o ke keleawe ma kahi o 1000 degere, a maʻalahi ke deformed e ka wela. ʻO ka mahana sublimation graphite he 3650 degere; ʻO ke coefficient o ka hoʻonui wela he 1/30 wale nō o ke keleawe.
(2) ʻoi aku ka māmā o ke kaumaha: ʻo ka nui o ka graphite he 1/5 wale nō o ke keleawe, hiki ke hoʻemi pono i ke kaumaha o ka mīkini hana (EDM) ke hana ʻia nā electrodes nui e ka hoʻokuʻu ʻana; ʻOi aku ka kūpono no ka hoʻopili ʻana o ka ʻōpala nui.
(3) ʻoi aku ka liʻiliʻi o ka hoʻohana ʻana i ka hoʻokuʻu ʻana; ʻOiai aia pū kekahi mau ʻātoma C i loko o ka ʻaila huna, i ka wā o ka hana hoʻokuʻu ʻana, ʻo ke kiʻekiʻe o ka mahana e hoʻopau ai i nā ʻātoma C i loko o ka ʻaila huna, kahi e hana ai i kahi ʻili pale ma luna o ka ʻili o ka electrode graphite, e uku ana no ka nalowale o ka electrode graphite.
(4) ʻaʻohe burrs; Ma hope o ka hana ʻia ʻana o ka electrode keleawe, pono e ʻoki lima ʻia e wehe i nā burrs, ʻoiai e hana ʻia ana ka graphite e kaHale hana ʻelektrika Graphiteme ka ʻole o nā burrs, kahi e mālama ai i nā kumukūʻai he nui a maʻalahi hoʻi ka hana ʻakomi
(5) ʻoi aku ka maʻalahi o ka graphite e wili a hoʻowali; ʻOiai ʻo ka graphite he hapakolu wale nō o ke kūpaʻa ʻoki o ke keleawe, ʻoi aku ka maʻalahi o ka wili a hoʻowali me ka lima
(6) ke kumukūʻai haʻahaʻa a me ke kumukūʻai paʻa; Ma muli o ka piʻi ʻana o ke kumukūʻai keleawe i nā makahiki i hala iho nei, ʻoi aku ka haʻahaʻa o ke kumukūʻai o ka graphite isotropic ma mua o ke keleawe. Ma lalo o ka nui like, ʻo ke kumukūʻai o nā huahana graphite maʻamau o ke kalapona toyo he 30% ~ 60% haʻahaʻa ma mua o ke keleawe, a ʻoi aku ka paʻa o ke kumukūʻai, ʻoi aku ka liʻiliʻi o ka loli o ke kumukūʻai pōkole.
Ma muli o kēia pono hoʻohālikelike ʻole ʻia, ua pani mālie ka graphite i ke keleawe ma ke ʻano he mea makemake ʻia no ka electrode EDM.
