- Ka holomua o ka Calcining
ʻO ka calcining ka hana mua o ka mālama ʻana i ka wela coke petroleum. Ma lalo o nā kūlana maʻamau, ʻo ka mahana o ka mālama wela wela ma kahi o 1300 ℃. ʻO ke kumu o ka wehe ʻana i ka wai, nā mea hoʻoheheʻe, sulfur, hydrogen a me nā mea haumia ʻē aʻe i loko o ka petroleum coke, a e hoʻololi i ke ʻano a me nā waiwai physicochemical o nā mea kalapona like ʻole. Hiki i kēia ʻano hana ke hoʻemi i ka ʻike hydrogen o ka huahana coke petroleum regenerated, hoʻomaikaʻi i kona degere graphitization, a pēlā e hoʻomaikaʻi ai i kona ikaika mechanical, density, conductivity uila a me ka pale oxidation.
I kēia manawa, ʻo ka calcining o ka petroleum coke ma Kina e hoʻohana nui i ʻehā mau ala: rotary kiln forging furnace, pot forging furnace, rotary furnace a me ka uila forging furnace. Ma muli o ke ʻano ʻokoʻa o kekahi mau kumu hoʻohālike umu, he ʻokoʻa nui hoʻi ka ʻenehana. Hoʻokumu i kahi hoʻonohonoho piha o ka hale a me nā haole electrolytic alumini pre-baked anode a me nā ʻoihana hana mua i hoʻomoʻa ʻia i ka ʻoihana o ka petroleum coke tank calcine furnace, ʻo ka hapa nui o ka rotary kiln i calcine, ke ʻano pahu ʻano calcine furnace e hoʻohana i ka wela e hele mai ana. ʻO ka brick refractory no ka hoʻomehana ʻole, ke ʻano hoʻomehana o ka rotary kiln e hoʻomehana ʻia e ke puhi kinoea pili pololei me ka mea.
Inā hoʻohana ʻia nā poloka kalapona cathode graphitized i ka hana ʻana i ka petroleum coke ma hope o ka hoʻopaʻa ʻana, a i ʻole ka hoʻohana ʻana i ka poloka kalapona anode i kālua mua ʻia o ka coke petroleum calcined, ʻoiai he ʻokoʻa ko lākou koi no nā mea maka, akā like kā lākou hana hana, ʻo ia hoʻi. ʻaʻole e hoʻohui i nā mea ʻē aʻe, i loaʻa i ka calcine coke ma hope o ka hoʻopili ʻana, hiki ke hoʻomaikaʻi maikaʻi i nā waiwai kino o ka coke maka, e like me ka conductivity uila, density, etc.
ʻElua mau kaʻina hana maʻamau o ka coke petroleum calcined, rotary kiln a me ka umu ipu hao. ʻO ka hapa nui o nā ʻoihana petrochemical haole e hoʻohana i ka rotary kiln e hana ai i ka petroleum coke, aʻo ka hapa nui o lākou e hoʻohana i ka umu pahu e hana ai i ka petroleum coke ma Kina.
He mea maʻalahi kona kaʻina hana, ʻo ka mea nui e hoʻomalu i ka manawa wela a me ka mahana, hiki ke hana i nā ʻano ʻano coke petroleum, akā ʻaʻole hiki ke hana i ka hoʻoheheʻe kiʻekiʻe. Hiki ke hana ia me ka ipuhao.
ʻOi aku ka nui o nā ʻoihana e hana nei e hoʻomohala i nā kaʻina hana ʻoi aku ka maikaʻi o ka pahu pahu pahu, me ka hoʻonui ʻana i ka hiki ke hoʻomaikaʻi i ka automation, ka wela a me ka hoʻomaʻemaʻe kinoea. No laila ʻo ka ʻenehana hana o ka umu ipu hao ke kuhikuhi nui o ka hoʻomohala ʻana i ka umu i ka wā e hiki mai ana.
Ma nā ʻāina ʻē, ua hoʻopau ʻia ke kaʻina hana forging o ka coke petroleum i loko o kahi hoʻomaʻemaʻe aila, a hoʻopili pololei ʻia ka coke petroleum i loko o ka mea hana forging. He haʻahaʻa loa ke kumukūʻai o ka petroleum coke i hana ʻia e nā hale hoʻoheheʻe o Kina no ka mea ʻaʻohe mea hana forging a kiʻi pū. I kēia manawa, ʻo Kina ka ʻaila coke a me ka lanahu forging ka mea nui i ka ʻoihana metallurgical, e like me nā mea kanu carbonization, nā mea kanu alumini a pēlā aku.
