Carburizing kaihoko, Kei te whakamahia i roto i te maitai me te makanga ahumahi, mo te carburizing, desulfurization me etahi atu rauemi awhina. Ko te mea tino whakamahia i roto i te ahumahi whakarewa rino me te rino ko te hanga mo te ihirangi waro i tahuna i roto i te tukanga o te whakarewa rino me te rino me te taapiri i nga matū kei roto.
I roto i te tukanga whakarewa o nga hua rino me te rino, he maha nga wa o te whakarewatanga, te wa e mau ana, te wa wera me etahi atu mea, ka nui ake te ngaro o nga huānga waro i roto i te rino wai, ka puta te heke o te ihirangi waro o te rino wai, e kore e taea e te ihirangi waro o te rino wai te eke ki te uara whakaaro o te whakamahine. Na reira, he mea tika ki te taapiri i nga hua carburizing ki te whakatika i te ihirangi waro o te rino, he taapiri awhina nui mo te hanga o te maitai-kounga teitei.
Carburizing kaihoko rite ki te hanga o te rauemi mata e taea te wehea ki: waro rakau, waro waro, coke waro, graphite.
1. Waro rakau
2. Waro momo waro
* Wao waro carburizer General: He hua o te pungarehu iti me te iti whanariki pai horoi anthracite i roto i te oumu calcination i muri i te 1250 ℃ teitei calcination pāmahana, te nuinga hua i roto i Ningxia, Inner Mongolia. Ko te ihirangi waro whānui ko te 90-93%. Kei te nuinga whakamahia te reira i roto i te hanga maitai hinonga, a ka whakamahia etahi hinonga maka ana i roto i te rino maka hina. Na te hanganga kiato o ona ngota ngota waro, he puhoi te whakamaarama wera, he roa te waa.
* Ko te waro kawa: he hua-a-hua o te waro tar hydrogenation hei whakaputa hinu. He waro teitei, iti whanariki me te iti hauota carburizer i tangohia mai i te ta. Ko te ihirangi waro kei waenga i te 96-99.5%, he iti te ihirangi wariu, he matotoru te hanganga, he teitei te kaha o te miihini me te whakakakahu i nga matūriki, he ngawari te whakamaarama.
* Ko te kaikawe carburizing kaihoko: te pupuhi waro, he kapu me te coke nui, hei taapiri atu ki te whakarewa, engari ka whakamahia ano hoki mo te waro utu whakarewa.
3. Coke (petroleum coke) waro
* Ko te carburizer coke calcined: He hua i hangaia mai i te iti-sulfur petroleum coke hei rauemi mata, ka tukatukahia i roto i te oumu calcination i te 1300-1500 nga nekehanga i muri i te tango i te makuku, te wariu me te poke. Ko te nuinga o nga wa e noho pumau ana i te 98.5%, a ko te nuinga o te waa he iti iho i te 0.5%, 1%. He kiato tona kiato, e kore e ngawari ki te pirau, me tona wa whakamahi he reo. Ko te nuinga o te whakaputanga i Shandong, Liaoning, Tianjin. Na tona utu me te tuku i roto i nga waahanga maha o te kaihoko carburizing he painga, he nui ake te whakamahi i te maakete.
* Kaihoko hinu kohukohu graphitic: kohi hinu i roto i te oumu whakarewa kauwhata i muri i te 3000 nga nekehanga o te whakangao teitei o nga hua graphitic, me te tere o te whakauru, te waro teitei me nga painga whanariki iti. Ko tona ihirangi waro he 98-99%, he iti iho te taupae ihirangi whanariki i te 0.05% ranei 0.03%, ko nga waahanga whakaputa kei roto i roto i Mongolia, Jiangsu, Sichuan me etahi atu. Ko tetahi atu huarahi ka puta mai i te graphite electrode tapahi ururua, no te mea ko te graphite electrode ano i muri i te maimoatanga graphitization, ka taea hoki te whakamahi i te para hei kaihoko carburizing mo nga mira maitai.
* Semi-graphitic petroleum coke carburizer: graphitic temperature is not as high as graphitic carburizer, carbon content is usually greater than 99.5, content sulfur is higher than graphitic carburizer, below 0.3%.
4. Momo kauwhata
* He rite ki te whenua-rite graphite carburizing kaihoko: ko te tono o te whenua-rite graphite i roto i te rino me te rino whakarewa whakarewa carburizing ranei, tona rohe whakaputa matua i roto i Hunan, ko te tono tika o te whenua-rite graphite paura, te nuinga o te waro ihirangi i roto i 75-80 %, ka taea te purea hei whakanui ake i te ihirangi waro hua.
* Kaitohu carburizing graphite taiao: te nuinga ki te graphite tihorea, ihirangi waro i roto i te 65-99%, iti pūmautanga, te tikanga whakamahia i roto i te mira maitai.
* Te kaihoko carburizing hiato: te paura graphite, te paura coke, te petroleum coke me etahi atu taputapu waewae, me te taapiri i nga here rereke me te miihini ka taea te pehia ki te ahua, mo te rakau kowhatu. Ko te nuinga o te waro kei waenga i te 93 me te 97%, a ko te whanariki he tino koretake, i waenga i te 0.09 me te 0.7.
