Lokacin da ake ƙara carbon a cikin ƙarfe mai ductile, ya kamata a zaɓi coke mai siffar graphitized petroleum ko kwal mai siffar calcined?

[] Ana ba da shawarar a zaɓi coke mai siffar graphitized a matsayin carburizer don ƙarfe mai ductile saboda waɗannan dalilai:

1. Mafi kyawun sinadaran abun da ke ciki:
   • Coke mai siffar man fetur: Yawanci yana ɗauke da fiye da kashi 99.5% na carbon da ƙasa da kashi 0.05% na sulfur. Yawan carbon da ƙarancin sulfur suna taimakawa wajen ƙara yawan carbon da ke cikin ƙarfe mai ductile yayin da suke rage mummunan tasirin sulfur akan nodularization da graphitization, ta haka ne ke hana lahani a cikin simintin.
   • Carburizer na anthracite da aka yi da calcined: Gabaɗaya yana da sinadarin carbon na kashi 90-93% da kuma sinadarin sulfur na kashi 0.3-0.5%. Ƙarancin sinadarin carbon da kuma yawan sinadarin sulfur na iya ƙara yawan sinadarin sulfur a cikin simintin, wanda hakan ke shafar tasirin nodularization da kuma halayen simintin.
2. Ingantaccen amfani da sha:
   • Coke mai siffar man fetur: Idan aka yi amfani da maganin graphitization mai zafi sosai, ana shirya ƙwayoyin carbon a cikin tsari, suna samar da tsarin flake graphite. Wannan yana sauƙaƙa narkewa da sha cikin sauri a cikin ƙarfe mai narkewa, wanda ke haifar da ingantaccen amfani da carburization da kuma ƙara yawan carbon ɗin da ke cikin ƙarfe mai narkewa yadda ya kamata.
   • Calcined anthracite carburizer: Da ƙarancin sinadarin carbon, yana narkewa a hankali kuma yana da ƙarancin ingancin sha, wanda zai iya tsawaita lokacin narkewar abinci da kuma ƙara yawan amfani da makamashi.
3. Tasirin nodularization da graphitization:
   • Coke mai siffar graphitized: Ƙarancin sinadarin sulfur yana rage tsangwama ga sinadarin nodularizing, yana taimakawa wajen cimma sakamako mai kyau na nodularization da kuma yanayin graphite, ta haka ne ke inganta halayen injiniya na ƙarfe mai aiki.
   • Calcined anthracite carburizer: Yawan sinadarin sulfur na iya tsoma baki ga tsarin nodularization, yana shafar nucleation da girma na graphite, wanda ke haifar da lalacewar halayen siminti.
4. Ingancin siminti:
   • Coke mai siffar graphitized: Amfani da shi yana haifar da ingantaccen ingancin ƙarfe na simintin ƙarfe, yana haɓaka ƙarfi da tauri na ƙarfe mai ƙarfi da rage lahani kamar porosity da raguwar nauyi, ta haka yana inganta ƙimar cancantar samfurin.
   • Calcined anthracite carburizer: Saboda yawan sinadarin sulfur da ke cikinsa, yana iya haifar da porosity a cikin simintin kuma yana rage halayen injiniya, wanda ke shafar ingancin simintin.
5. Kudin amfani:
   • Coke mai siffar graphitized: Duk da cewa farashinsa na iya ɗan fi na anthracite carburizer mai ƙamshi, ingancinsa mai yawa na carburization yana rage adadin carburizer da ake buƙata, wanda ke rage farashin narkewa. Bugu da ƙari, yana inganta ingancin samfura kuma yana rage ƙimar sharar gida, wanda ke haifar da ƙarancin farashin amfani gabaɗaya.
   • Calcined anthracite carburizer: Duk da cewa farashinsa ya yi ƙasa kaɗan, ƙarancin ingancin shan sa na iya buƙatar ƙarin amfani, kuma yana iya shafar ingancin siminti, wanda ke haifar da ƙarin farashin sarrafawa daga baya.
