Hoʻohana ʻia ʻo Carburizing agent i ka ʻoihana kila a me ka hoʻolei ʻana, no ka carburizing, desulfurization a me nā mea kōkua ʻē aʻe. ʻO ka mea nui loa i hoʻohana nui ʻia i ka ʻoihana hoʻoheheʻe hao a me ke kila, ʻo ia ka hana ʻana i ke kalapona i puhi ʻia i ke kaʻina o ka hao a me ka hoʻoheheʻe kila a me ka hoʻohui ʻana i nā mea i loaʻa i ke kalapona.
I ka hoʻoheheʻe ʻana o nā huahana hao a me ke kila, pinepine no ka manawa o ka hoʻoheheʻe ʻana, ka manawa paʻa, ka manawa overheating a me nā kumu ʻē aʻe, hoʻonui ka hoʻoheheʻe ʻana o nā mea kalapona i ka hao wai, ka hopena i ka emi ʻana o ke kalapona o ka hao wai. ʻAʻole hiki i ka ʻike kalapona o ka hao wai ke loaʻa i ka waiwai theoretical i manaʻo ʻia o ka hoʻomaʻemaʻe. No laila, pono e hoʻohui i nā huahana carburizing e hoʻoponopono i ka ʻike kalapona o ke kila, kahi mea hoʻohui kōkua koʻikoʻi no ka hana ʻana i ke kila kiʻekiʻe.
ʻO ka carburizing agent e like me ka hana ʻana o nā mea maka hiki ke hoʻokaʻawale ʻia i: carbon carbon, carbon carbon, coke carbon, graphite.
1. Kalapona laau
2. Kāpona ʻano lanahu
* ʻO ka mea hoʻoheheʻe lānahu calcining maʻamau: He huahana ia o ka lehu haʻahaʻa a me ka liʻiliʻi sulfur holoi holoi anthracite i loko o ka umu calcination ma hope o 1250 ℃ kiʻekiʻe wela calcination, hana nui ʻia ma Ningxia, Inner Mongolia. ʻO 90-93% ka nui o ke kalapona. Hoʻohana nui ʻia ia i nā ʻoihana hana kila, a hoʻohana ʻia kekahi mau ʻoihana hoʻolei i ka hao hina hina. Ma muli o ke ʻano paʻa o kāna mau molekala kalapona, ua lohi ke kaʻina hana hoʻoheheʻe wela a lōʻihi ka manawa.
* Asphalt coking carburizer: kahi huahana o ka lanahu tar hydrogenation e hana ai i ka aila. He kalapona kiʻekiʻe, haʻahaʻa sulfur a haʻahaʻa nitrogen carburizer i unuhi ʻia mai ke kā. Aia ka ʻike kalapona ma waena o 96-99.5%, haʻahaʻa ka haʻahaʻa haʻahaʻa, paʻa ke ʻano, ʻoi aku ka kiʻekiʻe o ka ikaika mechanical a me ka pale ʻana o nā ʻāpana, maʻalahi ka graphitization.
* Metallurgical coke carburizing agent: coking lanahu puhi, mea maʻamau cupola me ka nui coke, ma ka hoʻoheheʻe 'ana, akā, ua hoʻohana 'ia no ka metala uku carburizing.
3. Coke (petroleum coke) kalapona
* Calcined coke carburizer: He huahana ia i hana ʻia me ka liʻiliʻi sulfur petroleum coke e like me ka mea maka, i hana ʻia i loko o ka umu calcination ma 1300-1500 degere ma hope o ka wehe ʻana i ka moisture, volatiles a me nā haumia. ʻO ka maʻiʻo kalapona paʻa ka mea maʻamau ma kahi o 98.5%, a ʻo ka nui o ka sulfur ma lalo o 0.5% a i ʻole 1%. ʻAʻole maʻalahi ka decompose, a ʻo kona manawa hoʻohana he ʻano. Hoʻokumu nui ʻia ka hana ma Shandong, Liaoning, Tianjin. Ma muli o kāna kumukūʻai a me ka hāʻawi ʻana i nā ʻāpana he nui o ka carburizing agent he pono, ʻoi aku ka nui o ka mākeke.
* Graphitic petroleum coke carburizing agent: petroleum coke i ka graphitic smelting furnace ma hope o 3000 degere o ke kiʻekiʻe wela hana o graphitic huahana, me ka wikiwiki absorption, kiʻekiʻe kalapona a me ka haʻahaʻa sulfur pono. ʻO 98-99% kona kalapona, ʻoi aku ka haʻahaʻa o ka sulfur content index ma mua o 0.05% a i ʻole 0.03%, nā wahi hana i hoʻopaʻa ʻia ma Inner Mongolia, Jiangsu, Sichuan a pēlā aku. ʻO kekahi ala mai ka graphite electrode ʻoki ʻōpala, no ka mea, ʻo ka graphite electrode ponoʻī ma hope o ka mālama ʻana i ka graphitization, hiki ke hoʻohana ʻia ka ʻōpala e like me ka carburizing agent no nā wili kila.
* Semi-graphitic petroleum coke carburizer: ʻaʻole kiʻekiʻe ka mahana o ka graphitic e like me ka carburizer graphitic, ʻoi aku ka nui o ke kalapona ma mua o 99.5, ʻoi aku ka nui o ka sulfur ma mua o ka carburizer graphitic, ma lalo o 0.3%.
4. ʻAno graphite
* E like me ka honua graphite carburizing agent: ʻo ia ka hoʻohana ʻana o ka honua-like graphite i ka hao a me ke kila hoʻoheheʻe ʻana a i ʻole ka hoʻolei ʻana i ka carburizing, kona wahi hana nui ma Hunan, ʻo ia ka hoʻohana pono ʻana o ka lepo e like me ka graphite pauka, ka maʻamau kalapona ma 75-80 %, hiki ke hoʻomaʻemaʻe ʻia e hoʻonui i ka ʻike kalapona huahana.
* ʻO ka graphite carburizing agent: ka mea nui i ka flake graphite, carbon content i 65-99%, haʻahaʻa haʻahaʻa, hoʻohana maʻamau i nā wili kila.
* Composite carburizing agent: graphite pauda, coke pauka, petroleum coke a me na mea wawae e ae, e hoʻohui i nā mea hoʻopaʻa like ʻole me ka mīkini hiki ke paʻi ʻia i ke ʻano, no ke koʻokoʻo granular. ʻO ka maʻiʻo kalapona ma waena o 93 a me 97%, a ʻaʻole paʻa loa ka ʻike sulfur, ma waena o 0.09 a me 0.7.
