I kagraphite electrodeno ka hana kila a i ʻole anode paste no ka alumini a me ka magnesium (melting electrode), i mea e hoʻokō ai i ka coke petroleum (coke) i nā koi, ua calcined ka coke.Ua manaʻo ʻia ka mahana o ka calcination, ka petroleum coke volatiles.

(1) Wehe i ka makū a me nā mea maʻalahi mai nā mea maka

Hiki ke hoʻopauʻia ka maʻi maʻamau o nā mea maka e ka calcination, pēlā e hoʻonui ai i ka maʻi kalapona paʻa o nā mea maka.Hoʻopau ʻia ka wai i loko o nā mea maka e ka calcination, kahi kūpono i ka ʻoki ʻana, ka nānā ʻana a me ka hana wili, hoʻomaikaʻi i ka hana adsorption o nā kumu kalapona i ka binder, a hoʻomaikaʻi i ka maikaʻi o nā huahana.

(2) Hoʻonui i ka nui a me ka ikaika mechanical o nā mea maka

Ma hope o ka calcined, emi ka mea kalapona i ka leo, hoʻonui i ka nui a me ka ikaika ma muli o ka hoʻopau ʻana i nā volatiles, a loaʻa ka ʻoi aku ka maikaʻi o ka wela, no laila e hōʻemi ana i ka emi ʻana o nā huahana i ka wā calcination.

(3) E hoʻomaikaʻi i ka conductivity o nā mea maka

Ma hope o ka calcination, hoʻoneʻe ʻia nā volatiles, a hoʻololi pū ke ʻano molekala, e hōʻemi ana i ka resistivity uila a hoʻomaikaʻi i ka conductivity uila o nā mea maka.ʻO ka mea maʻamau, ʻoi aku ka kiʻekiʻe o ka calcination, ʻoi aku ka maikaʻi o ka conductivity o nā mea calcined.

(4) E hoʻomaikaʻi i ka pale ʻana o ka oxidation o nā mea maka

Ma hope o ka calcination, e like me ka piʻi ʻana o ka mahana o ka carbon raw material, e hoʻokuʻu ʻia nā mea haumia e like me ka hydrogen, oxygen a me ka sulfur ma o ke kaʻina pyrolysis a me ka polymerization, a e emi iho ka hana kemika a lilo nā waiwai kino a me nā kemika, pēlā e hoʻomaikaʻi ai i ka oxidation. kū'ē i nā mea maka.

Hoʻohana nui ʻia ka char Calcined i ka hana ʻana ographite electrode, nā huahana kalapona kalapona, carborundum, ʻoihana phosphorus meaʻai, ʻoihana metallurgical a me ka carbide calcium, ma waena o ka graphite electrode ka mea i hoʻohana nui ʻia.A hiki ke hoʻohana pololei ʻia ka coke me ka ʻole o ka puhi ʻana no ka calcium carbide ma ke ʻano he kumu nui, ka hana ʻana o ka silicon carbide a me ka boron carbide e like me nā mea wili, akā no ka hoʻolei ʻana me ka coke paʻa a me nā mea ʻē aʻe.
