Nā noi o nā recarburizers like ʻole

ʻO Carburizer kahi mea kemika e hiki ke hoʻomaikaʻi maikaʻi i ka hopena carbonization o nā mea a me ke kaiapuni metallurgical.Nui nā carburizer i hoʻohana ʻia i ka ʻoihana hao a me ke kila.Loaʻa nā hopena like ʻole i nā recarburizers no nā kumu like ʻole.

1. Mea hana graphite recarburizer
ʻO ka mea nui o ka graphite artificial ʻo ia ka pauka calcined petroleum coke, kahi i hoʻohui ʻia ai ka pitch (a i ʻole ka pregelatinization organik maʻemaʻe) ma ke ʻano he binder, a hoʻohui ʻia kahi mea liʻiliʻi o nā mea kōkua.Me nā ʻano mea like ʻole, paʻi ʻia a hana ʻia, a laila hana ʻia i loko o kahi lewa non-oxidizing ma 2500-3000 ° C e hana i ka graphitized.Ma hope o ka mālama ʻana i ka wela kiʻekiʻe, hoʻemi nui ʻia ka ʻike o ka lehu, sulfur a me ke kinoea.

Ma muli o ke kumu kūʻai kiʻekiʻe o nā huahana graphite artificial, hoʻohana ka hapa nui o nā mea hoʻohana hou ʻana i nā mea hana hou e like me nā chips, nā electrodes a me nā poloka graphite i ka wā e hana ai i nā electrodes graphite i nā foundries e hōʻemi i nā kumukūʻai hana.I ka hoohehee ana i ka hao ductile, i mea e hana ai i ka maikai metala o ka mea hoolei hao, o ka recarburizer pono he graphite artificial.

Ka hoʻohana ʻana i ka graphite recarburizer: Hiki i ka Graphite recarburizer ke hoʻomaikaʻi i ke ʻano metallographic o nā castings, e hoʻohua koke i ka graphite core i ka hao hao, e hoʻopōkole i ka manawa carbonization, a hoʻomaikaʻi i ka hopena carbonization.

2. ʻO ka ʻaila coke recarburizer
ʻO ka Petroleum coke kahi recarburizer i hoʻohana nui ʻia, a ʻo ka petroleum coke kahi huahana o ka hoʻomaʻemaʻe ʻaila.Hiki ke hoʻohana ʻia ke koena o ka aila a me ka petroleum pitch i loaʻa ma ka kaomi ʻana a i ʻole ka hoʻoheheʻe ʻana i ka ʻaila ma ke ʻano he kumu waiwai no ka hana ʻana i ka petroleum coke, a hiki ke loaʻa ka petroleum coke ma hope o ka coking.ʻOi aku ka liʻiliʻi o ka ʻaila coke maka ma mua o ka nui o ka aila ʻaila, a ʻoi aku ka kiʻekiʻe o nā mea haumia o ka coke petroleum maka, no laila ʻaʻole hiki ke hoʻohana pololei ʻia e like me ka carburizer a pono e calcined mua.He ʻano ʻano spongy, nila, granular a me ka wai ʻōmaʻomaʻo coke petroleum coke.

Ka hoʻohana ʻana i ka petroleum coke recarburizer: Hiki i ka Petroleum coke recarburizer ke hoʻonui i ka wela o ka umu, ʻaʻole hiki ke hoʻonui wale i ka wela o ka umu, akā hoʻomaikaʻi hoʻi i ka hua metallurgical, hoʻomaikaʻi a hoʻomaikaʻi i ke kaiapuni metallurgical paʻakikī.

3. Coke a me Antracite

I loko o ke kaʻina hana hana kila arc arc, hiki ke hoʻohui ʻia ka coke a i ʻole anthracite ma ke ʻano he recarburizer.ʻAʻole hoʻohana pinepine ʻia ka induction smelting iron ma ke ʻano he recarburizer ma muli o kona lehu kiʻekiʻe a me ka ʻoluʻolu.Hoʻopili ʻia ka calciner me ka anthracite, a ʻo ka mahana calcination he 1200-1300.ʻEleʻele ʻeleʻele, ʻulaʻula metala, kalapona paʻa 85-93, ʻoluʻolu sulfur a me ka maʻiʻo nitrogen.
Hoʻohana i ka recarburizer lanahu calcined: ʻO ke kumu o ka recarburizer lanahu calcined e hoʻonui pono i ke kalapona a hoʻopōkole i ka manawa carbonization.Hiki i ka hoʻohana ʻana i ka calcined coal recarburizer ke mālama pono i ka manawa.
