I. Inganta Tsarin Carbon: Tsalle Mai Inganci daga "Hatsi Mai Tsami" zuwa "Shinkafa Mai Tsabta"
Ƙarin sinadarin carbon na yau da kullun (kamar coke mai ƙamshi) yana da tsarin atom na carbon mara tsari, tare da ƙimar sha na kashi 60% kawai. Sabanin haka, coke mai ƙamshi, wanda aka yi wa magani mai zafi a 2800℃, yana samar da tsari mai layi na graphite na yau da kullun kamar "katunan wasa masu tarin yawa." Wannan tsari yana ba shi damar narkewa cikin sauri a cikin ƙarfe mai narkewa, tare da ƙimar sha yana ƙaruwa zuwa sama da kashi 90%. Misali, lokacin da ake narkar da ƙarfe mai ɗauke da ƙarfe (GCr15), dole ne a sarrafa adadin carbon daidai gwargwado a cikin kewayon 1.05%-1.15%. Yin amfani da ƙarin carbon mai ɗauke da graphitized yana tabbatar da daidaiton ƙimar sha na kashi 92%, tare da canjin abun cikin carbon bai wuce ±0.02% ba, don haka hana karyewar karyewa ko rashin taurin bearings da ke haifar da karkacewar abun cikin carbon.
II. Tsarin Daidaita Tsarin Gina Jiki: Keɓance "Tsarin Abinci" don Karfe Mai Kyau
- Ƙarancin Tsabta: Tsarin graphitization yana canza sulfur, nitrogen, da sauran ƙazanta zuwa iskar gas da ke narkewa, yana rage yawan sinadarin sulfur zuwa ƙasa da 0.05% da kuma yawan sinadarin nitrogen zuwa ƙasa da 0.01%. Misali, ƙarfen silicon mara tsari wanda ake amfani da shi a cikin sabbin gidajen motocin makamashi yana buƙatar yawan sinadarin carbon da ke ƙasa da 0.005%, wanda ke buƙatar amfani da ƙarin sinadarin carbon mai graphitized mai tsafta. Hakazalika, ƙarfen nickel da ke amfani da shi don na'urorin fitar da iskar nukiliya dole ne ya kasance yana da yawan sinadarin nitrogen wanda bai wuce 0.01% ba, buƙatar da ƙarin sinadarin carbon na yau da kullun ba zai iya cika ba.
- Tsarin Daidaita Daidaito: Ta hanyar daidaita adadin ciyarwa da sigogin sarrafawa, ana iya sarrafa abubuwan da ke cikin abubuwan da ke cikin ƙarfe mai narkewa daidai. Misali, a cikin narkewar tanda ta lantarki, ana ƙara coke mai mai hoto tare da tarkacen ƙarfe da sauran kayan caji don guje wa yawan iskar shaka da ke haifarwa sakamakon yawan ciyarwa, yana tabbatar da cewa yawan carbon da ke cikin simintin ya cika ƙa'idodi.
III. Inganta Ingancin Ƙarfe: Daga "Rashin narkewar abinci" zuwa "Shan Ruwa Mai Inganci"
- Ƙara Yawan Shaye-shayen Carbon: Yawan shaye-shayen Carbon na coke mai siffar graphitized ya fi kashi 30% sama da na abubuwan da ake ƙarawa a cikin carbon na yau da kullun, ma'ana cewa ga kowane jin 10 na carbon da aka ƙara, ingantaccen sha yana ƙaruwa da jin 3. Wannan yana rage asarar carbon sosai yayin aikin ƙarfe kuma yana rage farashin samarwa.
- Rage Gurɓataccen Iska: Ƙarfin halayen sulfur da nitrogen na coke ɗin man fetur mai siffar graphitized yana rage fitar da sinadarin sulfur dioxide da nitrogen oxides yayin narkewa, wanda hakan ke daidaita buƙatun kiyaye makamashi da rage fitar da hayaki. Misali, amfani da coke ɗin man fetur mai siffar graphitized zai iya rage fitar da sinadarin sulfur oxide a cikin kamfanonin ƙarfe da fiye da kashi 50%.
IV. Biyan Bukatun Masana'antu Masu Kyau: Tsallakewa daga "Gidan Wutar Lantarki na Karfe" zuwa "Babban Ikon Karfe"
- Tallafawa Samar da Kayayyaki Masu Kyau: Coke mai siffar petroleum mai siffar graphitized muhimmin abu ne na samar da ƙarfe mai ƙarfi mai launin toka, ƙarfe mai silikon da ba a haɗa shi da tsari ba, gami da nickel, da sauran kayayyakin ƙarfe masu tsada. Misali, ƙera kayayyakin "hardcore" kamar flanges na injin turbine na iska da bututun wutar lantarki na nukiliya ya dogara ne akan tsarkinsa mai girma da kuma halayensa na yawan shan ruwa.
- Inganta Masana'antu: Yayin da masana'antar ƙarfe ta China ke canzawa zuwa ci gaba mai kyau da kore, "maye gurbin coke na man fetur mai siffar graphitized a cikin gida" yana ƙaruwa. Amfani da shi ba wai kawai yana haɓaka ingancin kayayyakin ƙarfe ba, har ma yana haɓaka ci gaban fasaha a duk faɗin sarkar masana'antu. Misali, wani kamfanin ƙarfe ya rage canjin yanayin carbon na ƙarfe mai ɗaukar nauyi daga ±0.05% zuwa ±0.02% ta hanyar amfani da coke na man fetur mai siffar graphitized, wanda ya haifar da ƙaruwar ƙimar cancantar samfura da kashi 15%.
V. Nazarin Shari'a: Tasirin "Hardcore" na Coke na Man Fetur Mai Graphitized
- Samar da Karfe Mai Lantarki: Bayan amfani da coke mai siffar graphitized, wani kamfani ya rage yawan canjin sinadarin carbon a cikin ƙarfe mai ɗaukar kaya daga ±0.05% zuwa ±0.02%, ya ƙara ƙimar cancantar samfurin da 15%, kuma ya ceci sama da yuan miliyan goma a asarar shara ta shekara-shekara.
- Sabbin Gidajen Motocin Mota Masu Makamashi: Ta hanyar amfani da man fetur mai siffar graphitized mai tsarki, yawan sinadarin carbon da ke cikin ƙarfen silicon mara tsari ya daidaita ƙasa da kashi 0.005%, wanda ya inganta ingancin motar da kashi 3% kuma ya ƙara yawan tuƙi da kashi 5%.
- Masu Tace Ƙarfin Nukiliya: An sarrafa sinadarin nitrogen a cikin ƙarfen nickel ƙasa da kashi 0.01%, wanda hakan ya hana lalacewar kayan da ke cikin sinadarin nitrogen mai yawa, sannan kuma ya tsawaita rayuwar kayan aiki da shekaru 20.
